Acyclovir is an antiviral medication used to treat infections caused by herpes viruses, including genital herpes, cold sores, shingles, and chickenpox. According to the sources provided, there are some potential side effects of acyclovir that patients should be aware of.
The most common side effects of acyclovir include nausea, vomiting, diarrhea, and headache [2]. These side effects are generally mild and go away on their own. However, if they persist or become severe, patients should contact their healthcare provider.
Less common but more serious side effects of acyclovir include allergic reactions, which can cause hives, difficulty breathing, and swelling of the face, lips, tongue, or throat [3]. Patients who experience any of these symptoms should seek medical attention immediately.
Acyclovir can also cause changes in kidney function, especially in patients with pre-existing kidney disease or those who are taking other medications that can affect kidney function [1]. Patients should inform their healthcare provider if they have a history of kidney problems or are taking any other medications.
Finally, acyclovir can interact with other medications, including probenecid and cimetidine, which can increase the levels of acyclovir in the blood and increase the risk of side effects [1]. Patients should inform their healthcare provider of all medications they are taking, including over-the-counter medications and supplements.
In summary, while acyclovir is generally well-tolerated, there are some potential side effects that patients should be aware of. The most common side effects include nausea, vomiting, diarrhea, and headache, while less common but more serious side effects include allergic reactions and changes in kidney function. Patients should inform their healthcare provider of any pre-existing medical conditions or medications they are taking to avoid potential interactions.
