Whether you’re managing cold sores, shingles, or genital herpes, understanding the cost of acyclovir at major pharmacies can help you plan and save. Access to affordable treatment is essential, whether you’re filling a prescription for the first time or managing ongoing outbreaks. Here’s a snapshot of typical prices at CVS, Walgreens, and Walmart, along with tips on how to get the best deal.
The price of acyclovir can vary between pharmacies, with CVS generally priced around $1.20 per pill, Walgreens at approximately 70 cents, and Walmart offering the most affordable option at 45 cents per pill.
Acyclovir, sold under the brand names Sitavig and Zovirax, is prescribed to treat outbreaks of cold sores, genital herpes, and shingles that are caused by members of the herpes family of viruses. Cold sores are most often attributed to herpes simplex 1, while genital herpes is associated with the herpes simplex virus 2.
Herpes Zoster Causes Shingles
Shingles, which occurs most often in adults who are 50 or over, is caused by herpes zoster, which is the name attached to an adult-onset reactivation of the varicella-zoster virus that causes chickenpox in childhood.
No virus in the herpes family has a cure, which means that once you contract one of these viruses, it will remain in your body for life. The viruses alternate between active and dormant phases. During an active phase, they take up residence in nerve cells.
What Is Acyclovir?
Also called aciclovir, acyclovir was hailed as a major step forward for antivirals when it was discovered in the 1970s within the cells of a sea sponge in the Caribbean. Before acyclovir, anti-viral treatments were extremely dangerous; they destroyed cells indiscriminately and killed any microorganism they found, hostile or benign.
Acyclovir was first made available in 1981. Since then, it has become one of the world’s essential medicines, with over 3 million prescriptions in the U.S. alone. In addition to shingles, cold sores, and genital herpes, acyclovir is used to treat herpes simplex encephalitis and herpes or shingles in the eyes. Today, patients can find it widely available at major pharmacies, with acyclovir at CVS often noted for its accessibility as well as its frequent use in outbreak treatment plans.

Acyclovir can also be used to treat or prevent herpes transmission between mother and newborn as well as other viral infections during pregnancy that might threaten both mother and child.
Acyclovir is usually taken as a pill, although it’s also available in intravenous form. Cream preparations are also available, for outbreaks on the skin.
Acyclovir works by helping stop viral cells from multiplying, typically happens during an active phase of the virus. Limiting this replication reduces the severity of outbreaks as well as how many you’ll experience.
Another common medication, valacyclovir, is a prodrug that turns into acyclovir as the body breaks down the drug.
Acyclovir Side Effects
In most cases, the most common side effects of acyclovir, affecting 1% to 10% of people who take it, include:
- Nausea and vomiting
- Headache
- Diarrhea
If you need to take intravenous acyclovir, go over your medical history closely and discuss the possibility of extremely rare side effects with your doctor.
Acyclovir and Pregnancy
Acyclovir is classified as a Class B drug for pregnancy, which means animal studies have shown no signs of birth defects but that there have been no studies in humans. Therefore pregnant people, or people who might become pregnant, can take acyclovir, and it’s recommended by the CDC to treat varicella in people who are pregnant.
If you’re breast-feeding, you may need to discontinue as acyclovir is expressed in breast milk.
Acyclovir Contraindications (Who Should Not Take Acyclovir)
Some people are resistant to acyclovir. If you’re taking immunosuppressants as part of an organ transplant procedure or if you have HIV or AIDS, speak with your doctor before you take acyclovir or related medications. Acyclovir is often included to prevent opportunistic outbreaks by herpes viruses for immunocompromised people, but it may interact with HIV/AIDS treatments, such as interferon, and antiretrovirals, such as zidovudine.
If you have liver or kidney concerns, be careful when taking acyclovir. With the liver, there’s concern that the liver may not fully break it down, while in the kidneys, especially in high concentrations, acyclovir can precipitate into crystals that then need to pass from the body. If you’re experiencing discomfort while urinating or other signs of kidney problems, see a doctor immediately.
If you’re taking probenecid to treat gout or hyperuricemia (elevated levels of uric acid in the blood), don’t take acyclovir unless your doctor clears it. Probenecid can increase how long acyclovir lingers in the body and in turn, it limits how effective probenecid is at clearing uric acid from the body. This effect is most pronounced if they’re taken together, so if you need to take both, stagger the times according to medical advice.
While allergic reactions to acyclovir are rare, they are possible. If you’ve had allergic reactions to antivirals in the past, request an allergy screen before taking acyclovir.
Are There Generic Versions of Acyclovir Available, and How Do They Compare in Price?
Yes, acyclovir is widely available in generic form, and that’s one of the main reasons it remains an affordable treatment option for herpes-related conditions. The generic version contains the same active ingredient as the brand-name drugs Zovirax or Sitavig, meaning it works just as effectively but usually costs less.
Generic acyclovir can be purchased at most major pharmacies in pill, cream, or ointment form. At some locations, including CVS, the generic is often priced lower than the brand-name alternatives. For patients tracking acyclovir CVS availability, generic options tend to provide the best value without compromising safety or effectiveness.
Acyclovir Pricing at Major Pharmacies
The cost of acyclovir can vary depending on the pharmacy, dosage, and whether you choose a brand-name or generic version. Here’s a general overview to help you plan:
- Acyclovir CVS – CVS often offers competitive pricing for both generic and brand-name acyclovir. Prices can also be reduced if you use their prescription discount programs or CVS CarePass benefits.
