naratriptan

What is the most important information I should know about naratriptan?

Do not take naratriptan within 24 hours before or after using another migraine headache medicine.

What is naratriptan?

Naratriptan is a headache medicine that narrows blood vessels around the brain. Naratriptan also reduces substances in the body that can trigger headache pain, sensitivity to light and sound, and other migraine symptoms.

Naratriptan is used to treat migraine headaches. Naratriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.

Naratriptan may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using naratriptan?

• severe or uncontrolled high blood pressure;
• past or present heart problems;
• history of coronary artery disease, heart attack, or stroke, including "mini-stroke";
• Wolff-Parkinson-White syndrome or other heart rhythm disorder;
• a blood vessel disorder or circulation problems that cause a lack of blood supply within the body;
• severe liver or kidney disease; or
• a headache that seems different from your usual migraine headaches.

To make sure naratriptan is safe for you, tell your doctor if you have:

• liver or kidney disease;
• high blood pressure, a heart rhythm disorder; or
• coronary heart disease (or risk factors such as diabetes, menopause, smoking, being overweight, having high cholesterol, having a family history of coronary artery disease, being older than 40 and a man, or being a woman who has had a hysterectomy).

How should I use naratriptan?

Your doctor may want to give your first dose of this medicine in a hospital or clinic setting to quickly treat any serious side effects that occur.

Follow all directions on your prescription label. Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.

Take naratriptan as soon as you notice migraine symptoms.

Do not take the second tablet until at least 4 hours have passed since you took the first tablet. Do not take more than 5 milligrams (mg) of naratriptan in 24 hours.

Tell your doctor if you have more than four headaches in one month (30 days).

Naratriptan can raise blood pressure to dangerous levels. Your blood pressure may need to be checked often while you are using this medicine. If you use naratriptan long-term, your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).

What happens if I miss a dose?

Since naratriptan is used as needed, it does not have a daily dosing schedule. Call your doctor if your symptoms do not improve after using naratriptan.

What happens if I overdose?
