Aciclovir generally has a good safety profile, but some people experience side effects. Headaches are common, alongside nausea and vomiting. Less frequently, you might notice diarrhea or abdominal pain. Skin reactions, such as itching or rash, are also possible. In rare cases, more serious side effects, including neurological issues like confusion or seizures, can occur. These are more likely with high doses or in individuals with kidney problems.
Kidney Function
Aciclovir is processed by your kidneys. If you have pre-existing kidney disease, your doctor will likely adjust your dosage or monitor your kidney function closely. Adequate hydration is important to help your kidneys flush out the medication. Drink plenty of fluids while taking aciclovir.
Drug Interactions
Aciclovir can interact with other medications, particularly those that are also processed by the kidneys. Always inform your doctor or pharmacist about all medications, supplements, and herbal remedies you’re taking to prevent potential drug interactions. This includes over-the-counter drugs.
Pregnancy and Breastfeeding
Discuss aciclovir use with your doctor if you are pregnant, breastfeeding, or planning a pregnancy. The potential benefits and risks need to be carefully weighed. The drug may pass into breast milk.
