Interactions
Ergometrine (Maleate) is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementAdrenalineCoadministration increases blood pressure by vasoconstriction due to alpha adrenergic agonist activity of ergot alkaloids.ModerateCoadministration is not recommended. If use then close clinical monitoring of response, tolerance and excessive vasoconstriction is recommended.EphedrineBoth agents acts additively and synergistically to produce vasoconstriction results in increased blood pressure.ModerateConcomitant use is considered contraindicated. Closely monitor for response and tolerance of patient. ErythromycinCoadministration increases concentration of ergotamine in the plasma causing untoward peripheral vasoconstrictionModerateCoadministration is not recommended. If use then close clinical monitoring of response, tolerance and excessive vasoconstriction is recommended.HalothaneHalothane decreases the oxytcic effects of ergonovine.MinorClosely monitor for change in efficacy during coadministration.Ketamine (HCl)MifepristoneOral contraceptive increase platelet aggregability and promote thrombus formationModeratesimultaneous use of ergometrine with oral contraceptives should be avoidedOxprenolol (HCl)simultaneous use of ergometrine and b- adrenoceptor blocker may increase peripheral vascular resistance. increase risk of vascular occlusion . simultaneous use of ergometrine and b- adrenoceptor blocker should be avoidedOxytocin These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required.
