Valacyclovir generally has a good safety profile, but some individuals experience side effects. Commonly reported reactions include headache, nausea, and abdominal pain. These are usually mild and temporary.
More serious, though less frequent, side effects include dizziness, fatigue, and allergic reactions such as skin rashes. If you notice any severe or persistent side effects, discontinue use and contact your doctor immediately.
Certain precautions are necessary. Kidney problems can affect how your body processes valacyclovir. Inform your doctor about any kidney issues before starting treatment. Similarly, if you have a history of neurological disorders, discuss this with your physician.
Valacyclovir might interact with other medications. Provide your doctor with a complete list of your current medications, supplements, and herbal remedies to avoid potential interactions. This includes prescription drugs, over-the-counter medicines, and even vitamins.
