Interactions between your drugs

Minor

magnesium salicylate carvedilol

Applies to: Mag-Phen (magnesium salicylate / phenyltoloxamine) and carvedilol

High doses of salicylates may blunt the antihypertensive effects of beta-blockers. The proposed mechanism is inhibition of prostaglandin synthesis. Low-dose aspirin does not appear to affect blood pressure. In addition, beta-blockers may exert an antiplatelet effect, which may be additive with the effects of some salicylates. Metoprolol may also increase aspirin absorption and/or plasma concentrations of salicylates; however, the clinical significance of this effect is unknown. Data have been conflicting. Until more information is available, patients who require concomitant therapy should be monitored for altered antihypertensive response whenever a salicylate is introduced or discontinued, or when its dosage is modified.

Drug and food interactions

Moderate

phenyltoloxamine food

Applies to: Mag-Phen (magnesium salicylate / phenyltoloxamine)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

magnesium salicylate food

Applies to: Mag-Phen (magnesium salicylate / phenyltoloxamine)

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
