ibuprofen diclofenac

Applies to: famotidine / ibuprofen and Voltaren (diclofenac)

GENERALLY AVOID: Concomitant use of more than one nonsteroidal anti-inflammatory drug (NSAID) at a time may increase the potential for serious gastrointestinal toxicity including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, or intestines. These events can occur at any time during NSAID use, with or without warning symptoms. The risk is dependent on both dosage and duration of therapy. Patients with a prior history of peptic ulcer disease and/or GI bleeding have a greater than 10-fold increased risk of developing a GI bleed during NSAID use compared to patients without a history. Additional risk factors include old age, alcohol use, smoking, and poor general health status.

MANAGEMENT: Concomitant use of more than one NSAID at a time should generally be avoided. Some authorities consider the concomitant use of more than one NSAID at a time to be contraindicated due to the absence of any evidence demonstrating synergistic benefits and the potential for additive adverse reactions (AU,UK). Patients treated with an NSAID should be advised to take it with food and to immediately report signs and symptoms of GI ulceration and bleeding such as severe abdominal pain, dizziness, lightheadedness, and the appearance of black, tarry stools. The selective use of prophylactic anti-ulcer therapy (e.g., antacids, misoprostol, proton pump inhibitors) may be considered in high risk patients.

Minor

ibuprofen famotidine

Applies to: famotidine / ibuprofen and famotidine / ibuprofen

H2 antagonists may alter the disposition of nonsteroidal anti-inflammatory drugs (NSAIDs), resulting in increased or decreased plasma concentrations. Data are varied, even for the same NSAID. The mechanism may be related to inhibition of metabolism, changes in gastric pH that decrease absorption, and/or reduced urinary elimination. Statistically significant changes have been small and of limited clinical significance. Clinical monitoring of patient response and tolerance is recommended.

Drug and food interactions

Moderate

ibuprofen food

Applies to: famotidine / ibuprofen

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.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

H2 antagonists may reduce the clearance of nicotine. Cimetidine, 600 mg given twice a day for two days, reduced clearance of an intravenous nicotine dose by 30%. Ranitidine, 300 mg given twice a day for two days, reduced clearance by 10%. The clinical significance of this interaction is not known. Patients should be monitored for increased nicotine effects when using the patches or gum for smoking cessation and dosage adjustments should be made as appropriate.

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.

Duplication

Nonsteroidal anti-inflammatories

Therapeutic duplication

The recommended maximum number of medicines in the 'nonsteroidal anti-inflammatories' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'nonsteroidal anti-inflammatories' category:

  • famotidine/ibuprofen
  • Voltaren (diclofenac)

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
