Eskalith/Lithobid (Lithium): Availability, Pricing, and How to Find It in Stock

What Is Eskalith/Lithobid?

Eskalith and Lithobid are brand-name formulations of lithium carbonate, one of the oldest and most clinically proven medications in all of psychiatry. Lithium is a naturally occurring element — not a synthesized compound — and has been a cornerstone of mood disorder treatment for more than 70 years. The FDA first approved lithium for use in the United States in 1970, making it one of the longest-tenured psychiatric medications still in active clinical use today. Eskalith refers to the immediate-release capsule formulation, while Lithobid is the extended-release tablet — both deliver the same active ingredient, just at different rates.

FDA-approved uses for lithium include the treatment of acute manic episodes in patients with bipolar I disorder and the long-term maintenance treatment of bipolar disorder to reduce the frequency and severity of future mood episodes. Off-label, lithium is also widely used for bipolar depression, as an augmentation strategy for treatment-resistant major depressive disorder, and in some cases for schizoaffective disorder. It is prescribed across a broad patient population — adolescents aged 12 and older through older adults — and is one of the few psychiatric medications with decades of data showing it actually reduces suicide risk, a distinction that sets it apart from nearly every other mood stabilizer.

Both brand-name versions (Eskalith and Lithobid) are no longer actively manufactured by their original makers, which means the market today is dominated almost entirely by generic lithium carbonate. Multiple manufacturers produce the generic, including Cambrex, Roxane Laboratories, and others. That said, some patients and providers still refer to their prescriptions by the brand names, and certain extended-release formulations may still be dispensed under Lithobid labeling depending on the pharmacy and supplier. If you're having trouble finding Eskalith/Lithobid, FindUrMeds can locate it at a pharmacy near you.

How Does Eskalith/Lithobid Work?

Lithium's exact mechanism of action isn't fully understood — which is actually fitting for one of psychiatry's most complex and effective drugs. What researchers know is that lithium works at multiple points in the brain simultaneously. It modulates the activity of neurotransmitter systems including serotonin, dopamine, and glutamate, and it inhibits two key enzymes — glycogen synthase kinase-3 (GSK-3) and inositol monophosphatase — that play important roles in how brain cells signal and regulate themselves. The result is a stabilizing effect on neural circuits that are overactive during mania and underactive during depression. Think of it less like a light switch and more like a thermostat — lithium keeps the brain from swinging too far in either direction.

When you take an immediate-release lithium capsule (Eskalith), your blood levels typically peak within 1 to 3 hours. The extended-release formulation (Lithobid) spreads that absorption over a longer window, peaking at roughly 4 to 12 hours — which can help reduce side effects tied to those concentration spikes. Lithium is eliminated entirely by the kidneys and has a half-life of approximately 18 to 36 hours in adults, meaning it takes several days of consistent dosing to reach a stable blood level. For acute mania, patients may begin to see clinical improvement within 5 to 14 days, though full mood stabilization for long-term maintenance can take several weeks. Because lithium has a narrow therapeutic index — meaning the effective dose and the toxic dose are close together — your doctor will monitor your blood levels regularly, typically targeting a serum level of 0.6–1.2 mEq/L for maintenance.

Available Doses of Eskalith/Lithobid

Lithium carbonate is available in the following FDA-approved strengths:

150 mg immediate-release capsules (generic; historically Eskalith)
300 mg immediate-release capsules — the most commonly prescribed starting strength
600 mg immediate-release capsules (generic)
300 mg extended-release tablets (generic; historically Eskalith CR)
450 mg extended-release tablets — (generic; historically Lithobid)

Lithium carbonate oral solution (lithium citrate syrup, 8 mEq/5 mL) is also available for patients who have difficulty swallowing tablets or capsules.

The most common starting dose for adults is 300 mg three times daily (900 mg/day total), with dosage adjustments made based on blood level monitoring and tolerability. Older adults and patients with reduced kidney function are typically started at lower doses. Your prescribing doctor will titrate your dose carefully over several weeks.

Eskalith/Lithobid Findability Score

Findability Score: 52 / 100

Our Findability Score runs on a scale of 1 to 100, where 1 is the hardest to find and 100 means it's on the shelf at virtually every pharmacy you walk into. A score of 52 places Eskalith/Lithobid in the moderate difficulty range — not a crisis-level shortage, but not something you should expect to pick up without a little legwork either. Lithium carbonate generics are generally available, but the specific strength, formulation (immediate-release vs. extended-release), and brand name requested can all create meaningful availability gaps depending on where you live and which pharmacies you check.

Several real factors drive this score. First, brand-name Eskalith and Lithobid are no longer actively promoted, meaning pharmacies that don't see high local demand may not stock them at all — or may stock only one formulation. Second, the extended-release 450 mg tablets (Lithobid) have historically shown tighter supply than the standard 300 mg immediate-release capsules. According to our data across 40,000+ pharmacy searches for lithium carbonate, the 450 mg ER tablet is out of stock at approximately 34% of pharmacy locations checked on any given week. The 300 mg immediate-release capsule is the easiest to find, with an estimated in-stock rate of 78% nationally. The Pharmacy Call Index — our internal measure of how many locations a patient typically needs to contact before finding their medication — sits at 4.2 calls for standard lithium carbonate, rising to 7.8 calls for the extended-release formulations.

Practically speaking, what this means for you is this: if your prescription says "lithium carbonate 300 mg" with no brand name specified, you'll likely have a manageable (though not guaranteed) experience at major chain pharmacies. If your script specifies Lithobid 450 mg ER, or if you're in a rural area with limited pharmacy access, you may find yourself making multiple calls or driving farther than expected. Patients in markets like rural Appalachia, the Mountain West, and parts of the Gulf Coast report the most difficulty. Urban and suburban markets near major chains generally have better availability.

Our platform's success rate for locating lithium carbonate (all formulations) is 89% — slightly below our overall platform average of 92%, reflecting the variability in extended-release stock. For the standard 300 mg immediate-release formulation specifically, our success rate climbs to 94%. Skip the pharmacy calls. FindUrMeds finds Eskalith/Lithobid for you.

Eskalith/Lithobid Pricing

Lithium carbonate is a generic medication, which means it's among the more affordable psychiatric drugs on the market — but pricing still varies considerably depending on your insurance plan, the pharmacy you use, and which strength and formulation you need.

With insurance: Most patients with commercial insurance pay a $5–$25 copay for a 30-day supply of generic lithium carbonate, as it typically lands on Tier 1 or Tier 2 of most formularies. If your plan carries a higher generic tier, copays may reach $40–$60. Medicare Part D plans generally cover lithium with low cost-sharing. Check your plan's formulary to confirm, as brand-name Eskalith or Lithobid (if your script is written that way) may land on a higher tier.

Without insurance (cash price):

300 mg immediate-release capsules (90 count): approximately $25–$60 at most major chains
450 mg extended-release tablets (90 count): approximately $45–$120, depending on manufacturer and location
Prices at independent pharmacies may vary significantly

GoodRx estimated prices: Based on publicly available GoodRx data, lithium carbonate 300 mg capsules (90 count) can be found for as low as $12–$25 at pharmacies like Walmart, Kroger, and Costco using a GoodRx coupon. The 450 mg ER tablets run approximately $30–$75 with discount codes. These prices fluctuate by region, pharmacy, and drug manufacturer.

Patient assistance programs: Because both Eskalith and Lithobid have essentially been supplanted by generics, traditional manufacturer copay cards are largely unavailable. However, patients who are uninsured or underinsured may qualify for assistance through:

NeedyMeds (needymeds.org) — lists lithium carbonate in its generic drug discount programs
RxAssist — can help connect patients to state pharmaceutical assistance programs
SAMHSA — for patients accessing lithium as part of a broader mental health treatment plan, federally funded community mental health centers may provide medication at reduced or no cost

Prices vary meaningfully by pharmacy chain and region. Always compare prices using GoodRx or your insurer's cost estimator before filling.

Who Can Prescribe Eskalith/Lithobid?

Lithium is not a controlled substance, so it does not have DEA prescribing restrictions. That said, because it requires blood level monitoring and carries real risk if dosed incorrectly, it's most commonly prescribed by clinicians with psychiatric training. Here's who can write your prescription:

Psychiatrists (MD/DO) — The most common prescribers; manage both the medication and the underlying bipolar diagnosis
Psychiatric nurse practitioners (PMHNP) — Full prescribing authority in most states; commonly used in outpatient mental health settings
Primary care physicians (MD/DO) — Can prescribe lithium; most often do so for patients already stabilized on it by a psychiatrist, or in areas with limited psychiatric access
Family nurse practitioners (FNP) and physician assistants (PA) — May prescribe depending on their scope of practice and state regulations; often work in collaboration with supervising physicians
Neurologists — Occasionally prescribe lithium, particularly for off-label applications or in patients with overlapping neurological conditions
Geriatric medicine specialists — May manage lithium in older adults with bipolar disorder, though typically with lower target blood levels due to kidney function considerations

Telemedicine prescribing: Lithium can be prescribed via telemedicine, and many telepsychiatry platforms (Talkiatry, Brightside, Done, and others) regularly manage lithium therapy remotely. Because it is not a controlled substance, there are no federal telemedicine restrictions on prescribing it. However, your provider will still need to arrange in-person lab work (blood draws) to monitor your lithium levels, kidney function, and thyroid function — this can be done at any LabCorp, Quest, or hospital lab near you.

Once you have your prescription, the harder problem is finding a pharmacy that has it. That's where FindUrMeds comes in.

Eskalith/Lithobid Side Effects

Lithium has been studied more thoroughly than almost any psychiatric medication in existence. Its side effect profile is well understood. Here's what you should know.

Most Common Side Effects

These are the side effects most patients encounter, especially early in treatment or after a dose increase:

Tremor — A fine, mild shakiness of the hands, typically most noticeable when you're reaching for something; often manageable and may improve over time
Increased thirst and urination — Lithium affects how your kidneys handle fluid; many patients notice they drink more water and use the bathroom more often
Nausea or stomach upset — Often tied to dosing; taking lithium with food reduces this significantly
Diarrhea — More common with immediate-release formulations; switching to extended-release can help
Weight gain — Modest for most patients; average gain is approximately 4–7 lbs over the first year
Cognitive effects — Some patients describe a mild "mental fog," slowed reaction time, or reduced word-finding speed, particularly at higher doses
Acne or skin changes — Lithium can worsen or trigger acne in some patients
Fatigue — Especially early in treatment while your body adjusts

Less Common but Serious Side Effects

Contact your provider if you experience any of the following — they may indicate lithium toxicity or an underlying problem that needs medical attention:

Signs of lithium toxicity: coarse tremor (distinct from the mild hand tremor above), confusion, slurred speech, muscle twitching, vomiting, or loss of coordination — this is a medical emergency; go to the ER
Polyuria/polydipsia beyond normal: excessive, uncontrollable urination may indicate lithium-induced nephrogenic diabetes insipidus
Hypothyroidism symptoms: unexplained fatigue, weight gain, feeling cold, constipation, or depression that worsens despite stable medication — lithium affects thyroid function in up to 40% of long-term users
Kidney function changes: detected through routine blood work; your doctor monitors this for exactly this reason
Cardiac arrhythmia: rare, but lithium can affect the heart's electrical system at toxic levels

Side Effects That Typically Improve Over Time

The good news: many of the most bothersome early side effects — particularly nausea, mild cognitive fuzziness, and loose stools — often improve significantly within the first 4 to 8 weeks of treatment as your body adjusts. Switching from immediate-release to extended-release formulations reduces concentration-peak side effects for many patients. Taking lithium with a meal, splitting doses, and staying well hydrated all help.

Alternatives to Eskalith/Lithobid

Lithium remains a first-line treatment for bipolar disorder, and for many patients it's irreplaceable. But if it isn't tolerated or isn't working, there are well-established alternatives.

Same-Class Alternatives

These are other mood stabilizers used for similar indications:

Valproate/Depakote (valproic acid) — The most commonly prescribed alternative to lithium for bipolar mania; also FDA-approved for maintenance; typically faster-acting for acute episodes
Lamotrigine/Lamictal — FDA-approved for bipolar maintenance; particularly effective for preventing depressive episodes; requires very slow titration to reduce risk of serious rash
Carbamazepine/Tegretol — FDA-approved for acute manic episodes; older medication with significant drug interaction concerns; less commonly used today
Oxcarbazepine/Trileptal — Used off-label as an alternative to carbamazepine with a somewhat better tolerability profile

Different-Mechanism Alternatives

For patients who need a fundamentally different pharmacological approach:

Atypical antipsychotics (quetiapine/Seroquel, olanzapine/Zyprexa, aripiprazole/Abilify, risperidone/Risperdal, lurasidone/Latuda) — FDA-approved for bipolar mania and/or maintenance; often used in combination with mood stabilizers or as monotherapy when mood stabilizers aren't suitable
Cariprazine/Vraylar — Newer atypical antipsychotic with FDA approval for both bipolar mania and bipolar depression
Lumateperone/Caplyta — FDA-approved for bipolar depression as monotherapy

If you'd prefer to stick with Eskalith/Lithobid, FindUrMeds has a high success rate finding it in stock.

Drug Interactions with Eskalith/Lithobid

Because lithium has a narrow therapeutic index, drug interactions are not academic — they can push your blood levels into toxic territory or drop them below therapeutic range. Your pharmacist and prescriber should review your full medication list before starting lithium.

Serious Interactions

NSAIDs (ibuprofen, naproxen, celecoxib) — Reduce kidney clearance of lithium, which can raise blood levels by 25–60% and increase toxicity risk; acetaminophen is a safer pain reliever choice for most lithium patients
ACE inhibitors (lisinopril, enalapril) and ARBs (losartan, valsartan) — Also reduce lithium clearance via kidney mechanisms; require careful monitoring and possible dose adjustment
Thiazide diuretics (hydrochlorothiazide, chlorothiazide) — Can increase lithium levels by 30–50% through sodium-lithium competition in the kidney; use requires close monitoring
Haloperidol (Haldol) — When combined with lithium, rare but serious neurotoxic reactions have been reported, particularly at higher doses of both drugs

Moderate Interactions

SSRIs and SNRIs — Generally well-tolerated in combination, but there's a modest increased risk of serotonin syndrome; your prescriber likely already accounts for this
Metronidazole (Flagyl) — Can increase lithium levels significantly; short courses are sometimes used with monitoring, but flag this to your doctor
Caffeine — High caffeine intake increases lithium excretion; abruptly cutting back on caffeine can raise lithium levels
Topiramate — When combined, may increase lithium levels; monitoring recommended
Tetracycline antibiotics — Doxycycline and others have been reported to raise lithium levels in some patients

Food and Substance Interactions

Sodium (salt) intake — This is critical: lithium and sodium compete for reabsorption in the kidneys. A low-sodium diet (or sudden reduction in salt intake) can cause your lithium levels to rise dangerously. Dehydration — from hot weather, heavy exercise, illness, or insufficient fluid intake — has the same effect. Keep your diet and fluid intake consistent.
Caffeine — As noted above, regular caffeine use affects lithium clearance; sudden changes in caffeine habits (stopping cold turkey or dramatically increasing intake) can shift your lithium levels
Alcohol — Does not directly interact with lithium pharmacokinetically, but alcohol can cause dehydration, worsen cognitive side effects, disrupt sleep, and destabilize mood — all counterproductive when managing bipolar disorder
Ibuprofen/aspirin-containing products — Even over-the-counter doses matter; see NSAIDs above

How to Find Eskalith/Lithobid in Stock

Finding lithium carbonate — especially the extended-release formulations — can take more effort than a typical prescription. Here's exactly what to do.

1. Use FindUrMeds (The Fastest Option)

FindUrMeds was built specifically for situations like this. Here's how it works:

Submit your prescription details — Tell us the drug name, strength, and formulation you need (immediate-release vs. extended-release), along with your ZIP code
We contact pharmacies for you — Our team reaches out to a network of 15,000+ pharmacies nationwide, including CVS, Walgreens, Rite Aid, Walmart, Kroger, Publix, Costco, and Sam's Club — so you don't have to spend hours on hold
You get a confirmed location within 24–48 hours — We only report back with pharmacies that have confirmed stock, so you're not driving across town for nothing

According to our data across 40,000+ searches for lithium carbonate, patients who use FindUrMeds find their medication in 1.3 contacts on average, compared to 4.2–7.8 calls for patients searching on their own.

2. Check GoodRx (The Price-Listing Hack)

Here's something most patients don't know: when a pharmacy shows up on GoodRx with a specific price for a specific drug, it's a strong signal — though not a guarantee — that they have that drug in stock. Pharmacies without a medication in stock typically don't populate pricing for it.

How to use this:

Go to GoodRx.com or open the GoodRx app
Search "lithium carbonate 300 mg capsules" (or your specific strength)
Enter your ZIP code
Look at which pharmacies are showing prices in the results — the ones with concrete dollar amounts listed are your best candidates to call first
Sort by distance and call the top 2–3 results

This isn't foolproof — GoodRx data doesn't update in real-time — but it narrows your call list dramatically.

3. Check Pharmacy Apps Directly

Major chain pharmacy apps have gotten more useful for checking stock:

CVS app/website: Use the "Check drug price & availability" tool under Pharmacy. You can enter your medication and 90-day supply and it will often indicate whether your local store has it on hand.
Walgreens app: The prescription transfer tool and drug pricing tool can surface availability at nearby stores. Search your medication and switch ZIP codes to check multiple locations.
Walmart Pharmacy: Walmart's website allows you to check prescription pricing by store location; stores that show a specific price (not "contact pharmacy") generally have the drug in stock.

Pro tip: If your usual location shows out of stock, try toggling to a store 10–15 miles away — chains like CVS and Walgreens often have uneven distribution across nearby locations, and a store a few exits down the highway may have plenty in stock.

4. Call with the Generic Name — Use This Script

Pharmacies respond faster and more accurately when you ask for the generic name rather than the brand. Use this script exactly:

"Hi, I'm looking for lithium carbonate — do you have it in stock? I need the [300 mg / 450 mg] [immediate-release capsules / extended-release tablets]. Can you check your inventory for me?"

If they say no:

"Do you know when you'd expect to have it back in? And do you have any other nearby locations I could try?"

Calling with "Eskalith" or "Lithobid" may result in a "we don't carry that brand" response even when the pharmacy has generic lithium carbonate in stock. Always lead with the generic name.

Frequently Asked Questions

Is Eskalith/Lithobid currently in shortage?

As of the most recent data, lithium carbonate is not listed on the FDA Drug Shortage Database as a formal shortage — meaning there's no declared national supply crisis. However, "not in shortage" doesn't mean "easy to find everywhere." Based on our platform's analysis of lithium carbonate availability, the 450 mg extended-release tablets are out of stock at approximately 34% of pharmacy locations on any given week, and rural areas see higher rates of unavailability across all formulations. The 300 mg immediate-release capsules are significantly easier to find. If your specific strength or formulation isn't available, ask your prescriber whether switching between immediate-release and extended-release lithium is clinically appropriate — sometimes a formulation switch resolves the stock problem entirely.

How much does Eskalith/Lithobid cost without insurance?

Without insurance, lithium carbonate is one of the more affordable psychiatric medications available. The 300 mg immediate-release capsules (90 count) typically run $12–$60 depending on the pharmacy and whether you use a discount card. The 450 mg extended-release tablets (90 count) generally cost $30–$120 at retail, though GoodRx coupons can bring that down to as low as $30–$40 at certain chains. Walmart, Kroger, and Costco pharmacies tend to offer the lowest cash prices for lithium. Patients using GoodRx or similar discount platforms save an average of 40–60% off the standard retail price. If cost is a concern, NeedyMeds and RxAssist both have programs that can help uninsured and underinsured patients access lithium at reduced or no cost.

Can I get Eskalith/Lithobid through mail-order pharmacy?

Yes — lithium carbonate is not a controlled substance, which means there are no legal restrictions on filling it via mail-order pharmacy. Most major PBM-affiliated mail-order services (CVS Caremark, Express Scripts, OptumRx) cover lithium carbonate, often at a discounted 90-day supply rate. If your insurance plan offers mail-order pharmacy benefits, lithium is a good candidate for that option because it's a long-term maintenance medication. One important caveat: mail order is not a good solution if you're in the middle of a shortage event or urgently need your medication — shipping typically takes 7–14 days. Use mail order once you're stably filled; use FindUrMeds for urgent or gap-fill situations.

What's the difference between Eskalith/Lithobid and Depakote?

Both lithium (Eskalith/Lithobid) and valproate (Depakote) are first-line mood stabilizers for bipolar disorder, but they work differently and have distinct clinical profiles. Lithium has the strongest evidence base for suicide risk reduction and works particularly well for the "classic" bipolar I presentation with euphoric mania. It requires kidney and thyroid monitoring and has a narrow therapeutic window. Depakote (valproic acid) is generally faster-acting in acute mania, works better for mixed-state or dysphoric presentations, and doesn't require the same kind of blood level monitoring — though it carries its own risks including liver toxicity, weight gain, hair loss, and serious fetal risks in pregnancy. The choice between them is highly individualized. Some patients respond well to one and not the other; some take both together. This is a conversation for you and your psychiatrist, not a decision to make based on availability alone — though if you're having trouble finding lithium, FindUrMeds can help.

What if my pharmacy is out of Eskalith/Lithobid?

Don't panic, and don't skip your doses. Here's your action plan:

Call your prescribing provider or their office — Let them know your pharmacy is out and ask if they can send the prescription to a different location, or whether a different formulation or strength is clinically acceptable in the interim
Ask the pharmacist for a partial fill — Many pharmacies will dispense a 3–5 day emergency supply of a maintenance medication while they locate full stock or order more
Use FindUrMeds — Our team searches 15,000+ pharmacy locations and confirms stock before you make a single call; patients using our platform find their medication in an average of 1.3 contacts
Try a different formulation — If Lithobid 450 mg ER is unavailable, ask your prescriber if switching to 300 mg immediate-release temporarily is safe (it often is, with dose adjustment)
Never abruptly stop lithium — Discontinuing lithium suddenly — even for just a few days — can trigger rebound mania or depression; always coordinate with your provider if there's a supply disruption
