Tums Dual Action (calcium carbonate / famotidine / magnesium hydroxide) Disease Interactions

There are 3 disease interactions with Tums Dual Action (calcium carbonate / famotidine / magnesium hydroxide):

Major

H2 Antagonists (Includes Tums Dual Action) ↔ Gi Bleeding

Severe Potential Hazard, Moderate plausibility

Applies to: Gastrointestinal Hemorrhage

Histamine H2 receptor antagonists should not be used in the presence of vomit with blood, or bloody or black stools. These might be serious conditions and the diagnosis needs to be ruled out.

Major

Magnesium Salts (Includes Tums Dual Action) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Magnesium is eliminated by the kidney. The serum concentration of magnesium is increased in patients with renal impairment. Magnesium toxicity includes CNS depression, muscular paralysis, respiratory depression, hypotension and prolonged cardiac conduction time. Disappearance of the patellar reflex is a useful clinical sign of magnesium intoxication. Therapy with magnesium should be administered cautiously and dosages should be modified in patients with compromised renal function. Clinical monitoring of serum magnesium levels is recommended.

Moderate

Famotidine (Includes Tums Dual Action) ↔ Renal Dysfunction

Moderate Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Famotidine is partially eliminated by the kidney as unchanged drug, the extent of which is dependent upon the route of administration (25% to 30% oral; 65% to 70% intravenous). The elimination half-life of famotidine may be prolonged considerably in patients with severe renal impairment (CrCl < 10 mL/min), possibly exceeding 20 hours and approaching approximately 24 hours in anuric patients. Since central nervous system adverse effects such as grand mal seizures and psychic disturbances have been reported in patients with moderate (CrCl < 50 mL/min) and severe renal impairment, dosage adjustments are recommended for these patients. Reducing the normally recommended dosage by one-half or prolonging the dosing interval to 36 to 48 hours may be appropriate, depending on the patient's clinical response.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

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.
