Valtrex 500mg, while generally well-tolerated, can cause side effects. The most common include headache, nausea, and diarrhea. These are usually mild and temporary, often resolving without intervention. Drink plenty of fluids to help alleviate nausea and diarrhea. Over-the-counter pain relievers, like acetaminophen, can manage headache pain.
Less Common Side Effects
Less frequent side effects encompass dizziness, fatigue, and stomach upset. If you experience dizziness, avoid driving or operating machinery until it subsides. Fatigue may respond to increased rest. Persistent stomach upset might benefit from smaller, more frequent meals. For any concerning side effects, contact your doctor immediately.
Serious Side Effects: Seek Immediate Medical Attention
Although rare, serious reactions include severe allergic reactions (rash, swelling, difficulty breathing), confusion, and seizures. These necessitate immediate medical help. Do not delay seeking treatment; your health is paramount.
