These rows are manufacturer reports to the FDA for Isocarboxazid Tablet — they do not necessarily cover every manufacturer that makes this drug. A company appears here only if it told the FDA it has a supply problem, so other makers may still have stock.

Why is Isocarboxazid Tablet in shortage?
Right now, the 10 mg Isocarboxazid (Marplan) tablets — specifically the 100-count bottle made by Lifsa Drugs LLC — are in limited supply. The FDA has this listed under the reason category of "Other," which basically means the specific cause of the shortage hasn't been publicly shared. Unfortunately, Lifsa Drugs LLC also hasn't given a timeline for when things will get back to normal — their estimated recovery date is listed as "to be determined."
So to put it simply, we know there's a supply problem with this particular product from this manufacturer, but we don't yet know exactly why or when it will be resolved. That's not a lot of information, I know, and I wish I could give you more details — but that's all that's been reported to the FDA at this time.

What should I do if I take Isocarboxazid Tablet?
Isocarboxazid tablets are currently on the FDA drug-shortage list. If you take this medicine, please keep taking it as prescribed while supply steadies.
This medicine comes in one strength, 10 mg, and that strength still has an available source. The manufacturer on this record, Lifsa Drugs LLC, reports it as limited availability, so your pharmacy may need a little extra time to order it. No strength is listed as completely unavailable right now.
The reported reason is listed only as "Other," and an estimated recovery date has not yet been set. One manufacturer is currently supplying this medicine, so it has not stopped being made — it is simply harder to get in the short term.
Here are practical steps you can take:
- Do not stop, skip, or change your dose on your own.
- Ask your pharmacy to order the 10 mg tablets; they can check wholesalers and manufacturers for available stock.
- If your pharmacy cannot locate it soon, ask your prescriber or pharmacist about your options rather than going without.
- Manufacturer contact numbers are listed on this page for reference, though your pharmacy usually handles those calls.
This is general, national information from FDA data and may not match your local pharmacy's stock, so please check with them directly.
- Don’t stop or change the medication on your own — talk to your prescriber first.
- If this is part of an ongoing or essential regimen (for example HIV treatment or prevention, seizure, heart, transplant, diabetes or mental-health medicines), do not skip or ration doses — contact your pharmacist or prescriber right away to arrange continued supply before you run out.
- Ask your pharmacy to check other manufacturers, strengths, package sizes, and nearby stores.
- Ask your prescriber whether a different strength, formulation, or the brand/generic version is appropriate.
