It is very important that you or your child take all the medicines that the doctor prescribes. A common mistake is to stop taking controller asthma medications when the symptoms improve. Symptom improvement is due to the medication, it does not mean the asthma is gone! Leaving asthma untreated has much bigger risks than any risks associated with the medications. Asthma may improve or worsen with changes in season and exposure to asthma triggers, therefore it is important to have regular check-ups to evaluate and monitor your asthma as medication changes are necessary from time to time.
Monoamine oxidase inhibitors (phenelzine, isocarboxazid), clonidine , selegiline , guanethidine, and ergotamines (ergotamine tartrate, dihydroergotamine mesylate) may increase blood pressure when used at the same time as ephedrine. Methyldopa or reserpine may reduce ephedrine levels in the blood and thereby lessen the effectiveness of ephedrine. Tricyclic antidepressants ( desipramine , amitriptyline , doxepin , and imipramine ) may block the effect of ephedrine. The carbonic anhydrase inhibitors acetazolamide and dichlorphenamide may increase ephedrine blood levels and the risk of side effects from ephedrine. Patients taking any medications should consult with their physician or pharmacist before starting OTC ephedrine.
