Medication Guidelines for Erectile Dysfunction (ED)

Your doctor may prescribe a medication for erectile dysfunction (ED). Medication needs vary for each person. Whatever the treatment protocol prescribed to you, it is a good idea to keep the following guidelines in mind when you're taking medication for ED:

Know the name of your erectile dysfunction drug and how it works. Know the generic and brand name, dosage, and side effects of your medication. Always keep a list of your medications with you.
Take your medication as directed. Do not exceed the dosage recommended by your doctor. Follow doctor guidelines in terms of taking the medication in relation to meals or other medications you may already be using.
Oral ED drugs should never be taken if you are on nitroglycerin or a medication containing nitrates. Serious and even lethal interactions may occur if they are combined. Make sure your doctor has a complete list of your current medications when he or she is prescribing medication for ED.
Keep a medicine calendar and note every time you take a dose of your ED drug. Your prescription label tells you how much to take at each dose, but your doctor may change your dosage periodically, depending on your response to the medication. On your medication calendar, you can list any changes in your medication dosage as prescribed by your doctor.
Do not take any over-the-counter drugs or herbal therapies unless you ask your doctor first.
Ask your pharmacist any questions you have about refilling your prescription. Do not wait until you are completely out of medication before filling your prescriptions.
When traveling, keep your medications with you so you can take them if needed.
Before having surgery with a general anesthetic, including dental surgery, tell the doctor or dentist in charge what medications you are taking. This applies to emergency care, as well. Always tell the attending doctor what medications you are taking before they administer care.
