Interactions between your drugs

Major

diclofenac valdecoxib

Applies to: diclofenac and valdecoxib

GENERALLY AVOID: Concomitant use of COX-2 inhibitors with other nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the potential for serious gastrointestinal toxicity including inflammation, bleeding, ulceration, and perforation. The risk is dependent on both dosage and duration of therapy.

MANAGEMENT: Concomitant use of COX-2 inhibitors with non-aspirin NSAIDs should generally be avoided. Some authorities consider this combination to be contraindicated due to the absence of any evidence demonstrating synergistic benefits and the potential for additive adverse reactions (AU,UK).

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
