Generic Acyclovir Price: What You Really Pay and Where to Save

When you need generic acyclovir, a widely used antiviral drug for treating herpes simplex and shingles. Also known as acyclovir tablets or capsules, it’s one of the most common prescriptions for cold sores, genital herpes, and shingles outbreaks. Most people don’t realize how much the price can vary—$5 at one pharmacy, $80 at another—just because of where you buy it and whether you’re paying cash or using insurance.

The herpes virus, a common infection that causes recurring outbreaks of blisters doesn’t care how much you pay, but your wallet does. Generic acyclovir works the same as the brand-name Zovirax—it blocks the virus from multiplying, shortens outbreak duration, and reduces severity. But unlike Zovirax, which can cost $100+ for a 30-day supply, generic versions often run under $15, even without insurance. You’ll find the lowest prices at large chain pharmacies, online pharmacies that verify prescriptions, or through mail-order services that offer bulk discounts.

It’s not just about the pill price, though. People often overlook how dosage affects cost. A 200mg tablet is cheaper per dose than a 400mg tablet if you need to take more pills. And if you’re treating frequent outbreaks, your doctor might prescribe daily suppressive therapy—this changes how much you buy at once and how often you refill. Some patients save hundreds a year by switching from brand to generic and ordering 90-day supplies instead of 30-day ones.

Don’t fall for the trap of thinking "cheap" means unsafe. The FDA requires generic acyclovir to match the brand in strength, purity, and how fast it works. The only difference? The label and the price tag. Look for FDA-approved manufacturers like Teva, Mylan, or Accord. Avoid websites that sell it without a prescription—those are scams or worse, counterfeit meds.

And if you’re treating shingles, time matters. The sooner you start acyclovir after the rash appears, the better the results. Delaying because you’re waiting for a prescription or trying to find the cheapest option can mean more pain and longer healing. That’s why knowing your options ahead of time—like which pharmacies carry the lowest prices or if your insurance covers generics—isn’t just smart, it’s practical.

There’s also a big gap between what people expect to pay and what they actually pay. Many assume insurance will cover it fully, but copays can still hit $20–$40. Others think online pharmacies are risky, but hundreds of thousands of people safely buy generic acyclovir online every year—when they pick licensed, verified pharmacies. The key is knowing how to spot the real ones.

Below, you’ll find real comparisons and buying guides from people who’ve been there—how they cut their acyclovir costs, which pharmacies they trust, what dosage works best for outbreaks versus prevention, and how to avoid the common mistakes that lead to overpaying. No theory. No fluff. Just what works.
