Interactions between your drugs

Moderate

pseudoephedrine sevoflurane

Applies to: Poly-Vent IR (guaifenesin / pseudoephedrine) and sevoflurane

Consumer information for this interaction is not currently available.

GENERALLY AVOID: The administration of volatile general anesthetics during therapy with indirect-acting sympathomimetics (e.g. methylphenidate, ephedrine) or their derivatives may increase the risk of hypertension and/or cardiac arrhythmias. The proposed mechanism is anesthetic-induced myocardial sensitization to the stimulation caused by sympathomimetics.

MANAGEMENT: Until more information is available, caution is advisable if volatile general anesthetics are administered concomitantly with indirect-acting sympathomimetics or any of their derivatives. If the combination is required, dosage adjustments are recommended, and the patient's hemodynamic status should be closely monitored. When surgery is planned, it is recommended that indirect-acting sympathomimetics or their derivatives be discontinued prior to the day of surgery. Prescribing information for individual products should be consulted.

Drug and food interactions

Moderate

pseudoephedrine food

Applies to: Poly-Vent IR (guaifenesin / pseudoephedrine)

Both pseudoephedrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
