What if I am taking other drugs?

Always provide your doctor with a list of all other drugs you are taking (including over-the-counter medications and herbal/natural products) as they may interact with and/or may change the safety or effectiveness of either drug. Inform your doctor if you are taking any of the following medications:

  • Medications in the classes of amphetamines, epinephrine, phenylephrine, or [pseudoephedrine] - may increase the risk of side effects . Many nonprescription products contain these medications (e.g., diet pills and medications for colds). Talk to your doctor or pharmacist
  • Beta blockers (e.g. metoprolol, timolol, propranolol, labetalol, carvedilol, nadolol, pindolol, sotalol) - may reduce the effects of fenoterol.
  • Theophylline, prednisone, methylprednisolone, dexamethasone, furosemide, hydrochlorothiazide – may increase risk of having low blood potassium
  • Other short-acting drugs that help with breathing (e.g. Salbutamol or Ventolin, terbutaline) – duplication of effect - increased risk of side effects such as heart palpitations, tremor and nervousness
  • Long-acting drugs that help with breathing (e.g. salmetrol, formoterol) – using fenoterol regularly with these drugs may increase risk of side effects such as heart palpitations, tremor and nervousness
  • Ma huang, ephedra, certain types of ginseng, caffeine – may increase risks of having tremors, difficulty sleeping, racing heart
  • amiodarone, quinidine, disopyramide, sotalol, propafenone, procainamide, thioridazine, haloperidol - may increase your chances of having heart rhythm problems
  • Monoamine oxidase inhibitors (MAOIs) e.g. phenelzine (brand name Nardil), tranylcypromine (brand name Parnate), moclobemide (brand name Manerix, generics available) isocarboxazid (available in the U.S.A. under the brand name Marplan) – risk of a serious rise in blood pressure – be aware of this while taking an MAOI or until 14 days after stopping an MAOI

Your doctor may need to make changes or monitor you more closely. If in doubt ask your doctor or pharmacist to review your list of medications.
