Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include: bronchodilators/decongestants/stimulants (such as epinephrine, pseudoephedrine, methylphenidate, amphetamine).

If you also take "triptan" migraine drugs (e.g., sumatriptan, rizatriptan), you will need to separate your "triptan" dose from your dose of this medication to reduce the risk of serious side effects. Ask your doctor how long you should wait between your doses of these drugs.

Some products have ingredients that could raise your heart rate or blood pressure. Tell your pharmacist what products you are using, and ask how to use them safely (especially cough-and-cold products, diet aids, or other migraine medications).
