DRUG INTERACTIONS: Midodrine may cause a decrease in the heart rate. Caution should be used when midodrine is given in other medications that may also reduce the heart rate such as cardiac glycosides, tricyclic antidepressants, beta blockers, and other agents.
Medications which have similar stimulatory effects on alpha-adrenergic receptors may enhance the pressor effects of midodrine. Examples of such medications include phenylephrine, pseudoephedrine, ephedrine, phenylpropanolamine, dihydroergotamine, and other agents that cause vasoconstriction.
Midodrine may compete with drugs such as metformin (Glucophage), cimetidine (Tagamet), ranitidine (Zantac), procainamide (Pronestyl), triamterene (Dyrenium), flecainide (Tambocor), and quinidine for elimination by renal tubular secretion (clearance through the kidneys). Caution should be used if midodrine must be used with any of these agents.
