Headache is a common side effect of Valtrex (valacyclovir), with some studies indicating it is one of the most frequently reported adverse effects. Fortunately, there are several effective strategies and precautions you can take to manage and potentially get rid of a Valtrex headache. This guide covers safe remedies and medical advice to help you feel better while continuing your treatment.

While Valtrex (valacyclovir) is generally well-tolerated by most healthy individuals, it can be a high-risk medication for certain vulnerable populations due to potentially severe side effects. The risk depends heavily on the patient's underlying health conditions, particularly kidney function and immune system status.

While generally well-tolerated, postmarketing reports confirm that valacyclovir can cause hives (urticaria) as part of an allergic reaction. Hives are a known, though not frequent, side effect of this widely used antiviral medication.
