Acetazolamide Shortage Update: What Patients Need to Know in 2026

If you take Acetazolamide — whether for glaucoma, altitude sickness, intracranial hypertension, or another condition — you may have heard about supply issues over the past few years. This guide gives you the latest information on Acetazolamide availability in 2026, what's changed since the shortage began, and what you can do right now.

Is Acetazolamide Still in Shortage?

Here's the good news: the most serious Acetazolamide shortage — the injectable (IV) form — has been resolved. In October 2022, the American Society of Health-System Pharmacists (ASHP) reported a shortage of Acetazolamide Sodium injection (500 mg vials). By February 2024, all marketed presentations of the injectable form were back in supply.

Oral tablets (125 mg, 250 mg) and extended-release capsules (500 mg) have generally remained available throughout the shortage period. However, some patients still report sporadic difficulty finding them at specific pharmacies. This isn't a formal shortage — it's more of a stocking and distribution issue.

Why Has Acetazolamide Been Hard to Find?

Even though the official shortage has been resolved, several factors can make Acetazolamide tricky to track down:

• Niche medication: Acetazolamide is prescribed for specialized conditions, so many pharmacies don't stock it in large quantities. A few prescriptions filling at the same time can empty a pharmacy's supply.
• Multiple manufacturers, uneven distribution: Generic Acetazolamide is made by Teva, Taro, Zydus, Lannett, and others. When one manufacturer has a production hiccup, pharmacies that rely on that supplier can run short.
• Seasonal demand spikes: Acetazolamide is the go-to medication for altitude sickness prevention. Demand rises during spring and summer hiking seasons, particularly near mountain destinations.
• Supply chain ripple effects: The broader pharmaceutical supply chain has been under strain. Even resolved shortages can leave lingering gaps as manufacturers and distributors rebuild stock levels.

How Much Does Acetazolamide Cost in 2026?

Price is another concern for patients. Here's what you can expect:

• Retail price (no insurance): A 30-day supply of generic Acetazolamide 250 mg (60 tablets) averages around $100 to $185 at retail.
• With a discount card: GoodRx can bring the cost down to as low as $16 to $25 for the same supply. SingleCare offers similar savings.
• With insurance: Most plans cover generic Acetazolamide as a Tier 1 or Tier 2 drug, with copays typically ranging from $0 to $15.
• Extended-release (500 mg capsules): These tend to cost more, starting around $21 to $40 with a discount card.

What If I Can't Find Acetazolamide at All?

If you've exhausted your options and truly cannot find Acetazolamide, talk to your doctor about alternatives.

Final Thoughts

The worst of the Acetazolamide shortage is behind us. The injectable form is back in supply, and oral formulations are widely available from multiple generic manufacturers. That said, individual pharmacies may still run out from time to time — it's the nature of a medication that's important but not widely stocked.

Your best strategy: plan ahead, use Medfinder to check stock before making the trip, and keep your doctor in the loop if you're having persistent trouble finding your medication. With a little planning, you can stay on top of your treatment without the stress.
