Acyclovir
About Acyclovir
Acyclovir belongs to a class of antiviral medication used to treat viral infections such as cold sores (an inflamed blister in or near the mouth, caused by infection with the herpes simplex virus), genital herpes (a common sexually transmitted infection marked by genital pain and sores), and herpes zoster (a viral infection that causes a painful rash). In addition to this, it is also used to treat chickenpox. Acyclovir does not cure herpes but prevents the infection spread and treats its symptoms.
Acyclovir contains acyclovir, which is an antiviral medication. Acyclovir prevents the multiplication of viruses in human cells by acting on its DNA, resulting in decreased viral overload. Acyclovir kills or stops the growth of fungi and treats the infection.
The dose and duration will depend on your condition and how you respond to Acyclovir. In some cases, you may experience headaches, dizziness, nausea, vomiting, diarrhoea, and sensitivity of the skin to sunlight. Most of these side effects of Acyclovir are temporary, do not require medical attention, and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.
Do not take Acyclovir if you are allergic to acyclovir or any of its ingredients. Check with your doctor if you are pregnant, currently breastfeeding, or taking other prescribed or non-prescribed medicines. Use protection while having sexual intercourse to avoid the transfer of genital herpes (a sexually transmitted disease) to your partner. If you have a weak immune system, please inform your doctor before taking Acyclovir as you may require a dose adjustment.
