Acyclovir and Valtrex are probably the most effective medications when it comes to treating herpes simplex virus (HSV). Although they both are effective in the treatment of this condition, they vary a lot in terms of structure, application, dosage, chemical ingredients, constitution and even price. Both of them are the primary choice for treating genital herpes. They can quickly contain and reduce the growth of the virus.

You have a better chance of treating the condition effectively when you start taking the medications right at the onset of the disease. The symptoms of herpes are fairly obvious which makes it all the more convenient to start your medications on time. Symptoms include tingling and pain in the genital area. If you observe these symptoms, it is best to consult a doctor immediately.

Comparing Valtrex and Acyclovir

Acyclovir, the older of the two have been in use since 1982 whereas Valtrex came into existence in 1995. Both are FDA approved and are widely available in the US. If you take a closer look, you will realize that Valtrex is a prodrug of Acyclovir. This means that when consumed, Valtrex is automatically converted into Acyclovir by the body. This ensures easier absorption and hence the results are faster and more pronounced. Therefore, you have to take lesser dosage of Valtrex when compared to taking Acyclovir directly.


While both Valtrex and Acyclovir are primarily used in the treatment of genital herpes, the former is also used for treating recurrent genital herpes. They work by reducing the virus’s reproductive capacity. Both of these are generally considered safe and no notable side effects have been reported. Doctors prescribe the medication taking into a wide array of factors including the patient’s current and past medical history, current medications, allergies, history of herpes etc.

Both are highly effective when used in the nascent stages of the infection. However, because Valtrex has a higher chance of getting absorbed and requires lesser dosage, some doctors prescribe it over Acyclovir. For episodic treatments, it has been observed that Valtrex is able to heal the sores much faster. When taken timely, it can even prevent the formation of blisters.

From the above, it is quite clear that there is no telling apart buying Valtrex and Acyclovir since their benefits and side effects are more or less the same. Still, differences exist in terms of dosage, price, application etc. It is best to consult a doctor before starting on either one of the two.
