Interactions between your drugs
trimeprazine hyaluronidase
Applies to: trimeprazine, Rituxan Hycela (hyaluronidase / rituximab)
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
trimeprazine food
Applies to: trimeprazine
GENERALLY AVOID: Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment. Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines. The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.
MANAGEMENT: Patients should be advised to avoid alcohol during phenothiazine therapy.
