Tiagabine Hydrochloride Tablet shortage
Tiagabine Hydrochloride Tablet is currently listed in shortage by the FDA. The FDA lists 4 affected products. This page was last refreshed from FDA data on Sep 23, 2026.
Teva is permanently stopping production of tiagabine hydrochloride tablets. Other makers — including Sun Pharmaceutical and Novadoz — have not reported a shortage and still list 2 mg and 4 mg strengths, though 12 mg and 16 mg tablets have no available source reported from any manufacturer.
Don’t stop or change your therapy on your own — talk with your prescriber about the plan that fits you, and ask your pharmacist what’s actually available (see options).

These rows are manufacturer reports to the FDA for Tiagabine Hydrochloride 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. That’s the basis for the Where else can I get Tiagabine Hydrochloride Tablet? options further down this page.
Why is Tiagabine Hydrochloride Tablet in shortage?
Teva Pharmaceuticals has reported to the FDA that they are permanently stopping the manufacturing of their tiagabine hydrochloride tablets. This affects all four strengths they made — the 2 mg, 4 mg, 12 mg, and 16 mg tablets — all in 30-count bottles. This isn't a temporary delay or a supply hiccup; Teva has stated this is a full discontinuation of these products.
It's worth knowing that the FDA did not share a specific public reason for why Teva made this business decision. Also, this report only covers Teva's products — it doesn't speak to what other manufacturers may be doing with their own versions of this medicine.

What should I do if I take Tiagabine Hydrochloride Tablet?
Tiagabine Hydrochloride tablets are currently on the FDA drug-shortage list, and I want to walk you through what this means so you can plan calmly.
This report covers all four strengths — 2 mg, 4 mg, 12 mg, and 16 mg (30-count bottles). Right now none of these strengths have an available source from the manufacturer that filed this report, Teva Pharmaceuticals. The reason given is that Teva is discontinuing manufacture of the drug. Because this is a discontinuation rather than a temporary delay, this particular supply may not return, so a conversation with your prescriber is a sensible next step. Keep in mind this report reflects only Teva — other makers may still supply this same medicine.
Please do not stop, skip, or change your dose on your own. Here is how to approach it:
- Ask your pharmacy to check wholesalers and other manufacturers for your strength.
- This same medicine (tiagabine) is also listed from Sun Pharmaceutical, Cephalon, and Novadoz. Your pharmacy may be able to source one of these, though it may not be in local stock right away.
- If your exact strength cannot be found, ask your prescriber or pharmacist about options, such as a clinician-chosen alternative.
Manufacturer contact numbers are listed on this page for reference; pharmacies usually handle those calls.
This is general information from national FDA data and may not match your local pharmacy's actual stock.
- 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.

Where else can I get Tiagabine Hydrochloride Tablet?
FDA shortages are manufacturer-reported — a company only shows up on the shortage list if it told the FDA it has a supply problem, so not every maker of Tiagabine Hydrochloride Tablet is necessarily short. Below we pull together the other still-marketed options that are not reported in shortage: the same medicine from manufacturers that haven’t reported a problem, and alternative dosage forms. These may still be out of stock at your pharmacy, and only your prescriber or pharmacist can decide what’s right for you.
