Interactions between your drugs
mesoridazine evening primrose
Applies to: mesoridazine, Primrose Oil (evening primrose)
Some clinicians have suggested that evening primrose and borage oil, both of which contain the omega-6 fatty acid gamma linolenic acid (GLA), may lower the seizure threshold and increase the risk of seizures during co-administration with other epileptogenic agents. However, data regarding the effect of gamma linolenic acid on seizure threshold are conflicting and limited.

Drug and food interactions
mesoridazine food
Applies to: mesoridazine
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.
