GlaxoSmithKline | Amerge (Medication)
Amerge is a headache medicine that narrows blood vessels around the brain. Amerge also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.
Amerge is used to treat migraine headaches. Amerge will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Amerge should not be used to treat a common tension headache, a headache that causes loss of movement on one side of your body, or any headache that seems to be different from your usual migraine headaches. Use this medication only if your condition has been confirmed by a doctor as migraine headaches. ...
Flushing, sensations of tingling/numbness/prickling/heat, weakness, drowsiness, or dizziness may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Chest/jaw/neck tightness can commonly occur shortly after using naratriptan. Only rarely are these signs of a serious condition. However, you may not be able to tell this apart from a serious reaction related to a lack of blood flow to the heart, brain or other parts of the body. Seek immediate medical attention if any of these unlikely but very serious (rarely fatal) side effects occur:chest pain, jaw/left arm pain, fainting, fast/irregular/pounding heartbeat, vision changes, weakness on one side of the body, confusion, slurred speech, sudden or severe stomach/abdominal pain, bloody diarrhea.
Tell your doctor immediately if any of these unlikely but serious side effects occur:blue fingers/toes/nails, cold sensation of hands/feet, hearing changes, mental/mood changes, seizures.
This medication may rarely cause a very serious condition called serotonin syndrome. The risk increases when this medication is taken with certain other drugs such as other triptans used to treat migraine headaches (e. g. , sumatriptan, zolmitriptan), certain antidepressants including SSRIs (e. g. , citalopram, fluoxetine, paroxetine) and NSRIs (e. g. , duloxetine, venlafaxine), or a certain drug to treat obesity (sibutramine).
In the unlikely event you have a serious allergic reaction to this drug, seek immediate medical attention. Symptoms of a serious allergic reaction include:rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. ...
Before taking Amerge, tell your doctor or pharmacist if you are allergic to naratriptan; or to other triptan migraine drugs; or it you have other allergies.
Prior to using this medication, consult your doctor or pharmacist if you have a history of:heart disease (e. g. , chest pain, heart attack), decreased blood flow in the brain (e. g. , stroke, transient ischemic attack), blood circulation disease (e. g. , ischemic bowel disease), uncontrolled high blood pressure (hypertension), certain types of headaches (hemiplegic or basilar migraine), kidney disease, liver disease.
Tell your doctor if you have the following risk factors for heart disease:diabetes, family history of heart disease, high blood pressure (controlled), high cholesterol, overweight, smoker, female after menopause, male over age 40.
This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.
The risk of heart disease, liver disease, and high blood pressure increases with age. The manufacturer does not recommend the use of naratriptan in the elderly since they may be more sensitive to the side effects, especially to an increase in blood pressure.
Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking naratriptan, call your doctor. If you are having surgery, including dental surgery, tell your doctor or dentist that you are taking naratriptan. ...
