Acyclovir

How is this medication used?

Acyclovir is usually taken with or without food, according to the directions on the prescription label, typically 2 to 5 times a day for 5 to 10 days, depending on the condition being treated. For the most effective results, it is often recommended to start taking acyclovir at the first sign of an outbreak as directed by your doctor. The dosage and length of treatment are based on your medical condition and response to treatment. For children, the dosage may also be based on weight.

What are the possible side effects?

Common side effects of acyclovir include nausea, diarrhea, headache, vomiting, and tiredness. Serious side effects can also occur and may include kidney problems (little to no urination, painful or difficult urination, swelling in your feet or ankles), easy bruising or bleeding, and a red or blistering skin rash. Get medical help right away if you experience any serious side effects.

What are the potential interactions?

Acyclovir can interact with other medications, herbs, or vitamins you might be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well. To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking. To find out how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.
