Is Acyclovir Still Hard to Get in 2026?

If you depend on Acyclovir for herpes, shingles, or another viral condition, you've probably heard the word "shortage" more times than you'd like. The question on every patient's mind is: Is Acyclovir still in shortage in 2026?

The short answer is: it depends on which form you need. The injectable (IV) form of Acyclovir has been experiencing intermittent shortages since 2020 and continues to have supply fluctuations. Oral Acyclovir — the tablets, capsules, and liquid that most patients take — is generally available, but individual pharmacies may still run out due to uneven distribution and increased demand.

In this article, we'll give you the full picture of what's happening with Acyclovir supply, what it costs in 2026, and how to make sure you can still get your medication.

The Acyclovir Shortage: A Timeline

Understanding how we got here helps explain the current situation:

• 2020-2021: The injectable form of Acyclovir began experiencing shortages due to manufacturing issues and increased demand during the pandemic. Oral forms were largely unaffected.
• 2022-2023: IV Acyclovir shortages continued. The FDA and ASHP (American Society of Health-System Pharmacists) added Acyclovir injection to their official shortage lists. Some hospitals had to ration IV Acyclovir or switch to oral alternatives when possible.
• 2024: Conditions began improving. Fresenius Kabi and other manufacturers increased production of Acyclovir sodium injection. ASHP noted that some presentations were back to full availability by November 2024. GlaxoSmithKline also boosted production of oral Acyclovir tablets.
• 2025-2026: The IV shortage is ongoing but improving. Oral Acyclovir is generally available at most pharmacies, though spot shortages at individual locations still occur due to demand-supply imbalances.

Why Is Acyclovir Hard to Find?

Several factors contribute to ongoing availability challenges:

Limited Manufacturers

Acyclovir is an older, off-patent medication with low profit margins. Few companies are willing to invest in manufacturing it, especially the injectable form. When one manufacturer has a production issue, the entire supply chain feels it.

Rising Demand

The number of Acyclovir prescriptions has been climbing steadily. Contributing factors include:

• Better awareness and testing for herpes simplex virus
• Growing use of suppressive therapy for genital herpes
• An aging population more susceptible to shingles
• Expanded telehealth access making prescriptions easier to obtain

Distribution Inequities

Even when Acyclovir is being manufactured in sufficient quantities, it doesn't reach every pharmacy equally. Large chains may get priority allocations from wholesalers, while smaller or rural pharmacies may face longer waits.

How Much Does Acyclovir Cost in 2026?

One positive aspect of Acyclovir is that it remains one of the more affordable prescription medications, especially as a generic:

• Average retail (cash) price: $70 to $105 for 60 tablets of 400 mg
• With a discount card (SingleCare, GoodRx): As low as $8 to $15 for the same quantity
• 800 mg tablets: Starting around $9.46 for 10 tablets with a coupon
• Brand Zovirax cream: $400+ without insurance (the generic cream is much cheaper)
• IV Acyclovir sodium: Around $4 to $25 per vial depending on the supplier

If you're paying out of pocket, a discount card can make a dramatic difference. Check our full guide on how to save money on Acyclovir in 2026.

New Options for Patients in 2026

While Acyclovir itself hasn't changed, the landscape around it has improved:

Telehealth Access

Getting an Acyclovir prescription has never been easier. Telehealth platforms can diagnose herpes infections and prescribe antivirals in a single virtual visit, often sending the prescription directly to a pharmacy with stock. Learn more about finding a prescriber near you.

Alternative Medications

If Acyclovir is unavailable, Valacyclovir (Valtrex) and Famciclovir (Famvir) are widely available and treat the same conditions. Valacyclovir is especially popular because it's taken less frequently and has better oral absorption. See our alternatives guide for details.

Online Pharmacies

Mail-order and online pharmacies like Cost Plus Drugs, Amazon Pharmacy, and Honeybee Health often maintain better stock levels for generic medications. They can ship Acyclovir directly to your home, which is ideal for patients on daily suppressive therapy.

Final Thoughts

The Acyclovir shortage situation in 2026 is better than it was a few years ago, but it's not fully resolved — especially for the injectable form. For oral Acyclovir, most patients can find their medication with a bit of effort, the right tools, and some flexibility.

The key is to plan ahead: don't wait until your last pill to refill, know your alternatives, and use resources like Medfinder to stay one step ahead of supply disruptions. And if cost is a barrier, discount cards and patient assistance programs can bring the price down to under $15 a month.
