Interactions between your drugs
magnesium salicylate hyaluronidase
Applies to: magnesium salicylate / phenyltoloxamine, hyaluronidase / ocrelizumab
Larger amounts of hyaluronidase may be required to achieve equivalent dispersing effects if patients are concomitantly receiving large doses of salicylates, cortisone, ACTH, estrogens, or antihistamines. These drugs may render tissues partially resistant to the dispersing action of hyaluronidase.

Drug and food interactions
phenyltoloxamine food
Applies to: 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.

magnesium salicylate food
Applies to: 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.
