Acyclovir Pills: Five Things You Should Know

Acyclovir, commonly manufactured by Zovirax, is used to treat infections caused by herpes viruses like genital herpes, cold sores around the mouth (herpes simplex), shingles (herpes zoster), and, in some cases, chickenpox. So, Acyclovir is antiviral, but it does not kill the virus rather it reduces the spread of infection, forming up of new spores, pain related to spores, and stuff like that. It can also increase your immunity to fight viruses.

In 2017, Acyclovir was the 166th most prescribed medicine in the USA with 3 million prescriptions. Howard Scheffer coinvented the drug Acyclovir while studying acycloadenosine as an antiviral drug with Robert Vince, S. Bittner, and S. Gurwara. Later, Schaeffer continued his work on acyclovir with Elion in Burroughs Wellcome. The U.S. patent of acyclovir was registered in 1979. The prescriptions started in 1981 onwards.

What are Acyclovir pills and how to use them?

So, every cell of our body has genetic material which is generally DNA. Similarly, herpes virus and poxvirus have DNA too. This DNA is composed of four nitrogenous bases Adenine, Guanine, Thymine, and Cytosine.

All these bases are mandatory for the formation of DNA and therefore all living life. Now, Acyclovir mimics viral Guanine. That is to say, when the virus comes in contact with Acyclovir, it misunderstands Acyclovir as Guanine and so, Acyclovir is added to the viral DNA chain instead of Guanine.

This stops the formation of the DNA chain, thus controlling the spread of the infection.

Doctors usually prescribe oral doses 2-5 times a day. Drinking plenty of fluids becomes necessary when taking any antiviral medicine (unless the doctor says otherwise). Also, by the mechanism mentioned above, you might’ve guessed that this medicine affects quantitatively. So, skipping doses is not a good idea. Always follow the doctor’s prescription regularly.
