Acyclovir (Zovirax)

What is acyclovir?

Acyclovir is a selective drug, a nucleoside analogue related to cytarabine, idoxuridine, trifluridine and vidarabine, active against herpesvirus 4 types (herpes simplex types 1 and 2, chicken pox (type 3), cytomegalovirus (type 4)). It slows down the growth and spread of the herpes virus in the body, by affecting their viral cells at the DNA level. This drug does not completely cure herpes, but reduces the symptoms of the infection and its acute course.
Acyclovir is used both for therapeutic treatment and for the prevention of relapses. It effectively eliminates skin rashes and foci of inflammation around it, prevents the spread of a viral pathogen (contamination), and reduces the complications of herpes.
The effect of acyclovir therapy is maximal when treatment is started early, especially with non-primary infection, which, as a rule, has a shorter course than the primary episode. Long-term prophylactic oral drug in patients with frequent episodes of genital herpes simplex completely suppresses relapses in most patients; as with other acyclovir-responsive infections, the viral latency period is not eradicated and the pre-treatment relapse rate returns after treatment is stopped.

Side effects of acyclovir

skin allergic manifestations (itching, soreness of the skin when touched, rashes);

nausea, which may be accompanied by vomiting, indigestion (diarrhea);

headaches and/or dizziness;

pain in the mouth when transbuccal (on the cheek) taking an acyclovir tablet.

Usually, cases of overdose with drug were recorded extremely rarely, but common manifestations are allergic reactions that entail a number of such symptoms:

hives, blisters, itching;

confusion and/or loss of consciousness;

numbness, burning or tingling in the upper and lower extremities;

temporary inability to move body parts.
