Valtrex, while generally well-tolerated, can cause side effects. The most common include headache, nausea, and diarrhea. These usually are mild and resolve without treatment. If they persist or worsen, contact your doctor.
Less Common Side Effects
Less frequent side effects involve dizziness, fatigue, and stomach pain. Some individuals experience changes in their blood counts, requiring monitoring. Rarely, Valtrex can affect the nervous system, leading to confusion or tremors. Allergic reactions, such as skin rash or itching, though uncommon, necessitate immediate medical attention.
Specific Considerations
Kidney problems can be exacerbated by Valtrex, so individuals with pre-existing kidney conditions should discuss this medication with their physician before use. Similarly, those with a history of neurological issues require careful assessment. Always inform your healthcare provider of all medications you’re taking to prevent potential interactions.
