Aciclovir oral tablets help treat viral infections and quicken the healing of blisters or sores for people suffering from chickenpox, herpes zoster, shingles, or genital herpes.
Aciclovir tablets are used to treat viral infections, including varicella-zoster (shingles), genital herpes, and chickenpox. Aciclovir is usually a part of combination therapy, so you might need to take it with other medication. But, this drug doesn’t cure herpes infections since the herpes virus can stay in your body for a long time and symptoms can manifest again later.
The herpes virus can manifest as cold sores in the mouth or as sores or blisters on your genitals, bottom, anus, or thighs if it is a genital herpes infection. Aciclovir belongs to a class of drugs called antivirals, and it works by lowering the ability of the herpes virus or other viral infections to multiply in the body. It does this by targeting the enzyme that the herpes virus needs to replicate and grow. This prevents the virus from creating red sores or blisters on your body.
This treats the symptoms of your infection but doesn’t work on eliminating the virus. The virus may continue to live on in your body even after finishing the prescribed course of this medication. The medication works best when there is a constant amount of medicine in your body. It is important to take the dose at regular intervals and at the same time every day.
Aciclovir is highly effective at treating and preventing viral infections, especially those caused by the herpes simplex virus, including genital herpes.
The recommended dose of Aciclovir for genital herpes is 400mg, and it works best if you take it at the first sign of symptoms of herpes-like sores or blisters. The recommended dose for Aciclovir is 400mg three times a day for 5 days. For suppressing genital herpes, Aciclovir 400mg should be taken twice a day. But this can vary according to your case and the doctor will prescribe you the medicine keeping in mind what's best for you.
