Zovirax, while generally safe, can cause side effects. Common reactions include headache, nausea, and diarrhea. Less frequent but more serious side effects involve kidney problems. Report any significant side effects to your doctor immediately.
Drug interactions are a concern. Zovirax may affect the efficacy of some medications, particularly those processed by the kidneys. Consult your physician about all medications you are taking, including over-the-counter drugs and supplements, before starting Zovirax treatment. This helps prevent potentially harmful combinations.
For example, concurrent use with probenecid can increase Zovirax levels in your blood, potentially leading to increased side effects. Similarly, concurrent use with mycophenolate mofetil can reduce its effectiveness. Always provide your physician with a complete medication history.
