Celebrex 200 mg (Celecoxib) and Valtrex 500 mg (Valaciclovir): interaction and safety
This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
Systemic NSAIDs may impair renal perfusion, adding to valaciclovir renal toxicity and facilitating aciclovir accumulation.
Clinical significance and safety
Celebrex 200 mg (Celecoxib) and Valtrex 500 mg (Valaciclovir): This is a precaution about potentially nephrotoxic medicines, not a measured risk rate for every individual pair. Dehydration, older age and kidney impairment increase concern. Check additional non-prescription painkillers with a clinician or pharmacist; kidney-function monitoring may be needed. Do not stop prescribed treatment yourself.
