Amerge oral Warnings
Amerge oral Uses
This medication is used to treat migraines. It helps to relieve headaches, pain and other symptoms of migraines, including sensitivity to light/sound, nausea, and vomiting. Prompt treatment allows you to get back to your normal routine and may decrease your need for other pain medications. Naratriptan does not prevent future migraines or reduce how often you may get a headache.
Naratriptan belongs to a group of drugs called triptans. It affects a certain natural chemical (serotonin) that constricts blood vessels in the brain. It may also block other pain pathways in the brain.How to use Amerge oral
Read the Patient Information Leaflet available from your pharmacist before you start using naratriptan and each time you get a refill. Ask your doctor or pharmacist if you have any questions.
Take one tablet by mouth with or without food, at the first sign of a migraine, or as directed by your doctor. Do not take naratriptan to prevent a migraine. If there is no improvement in your symptoms, do not take any more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may take a second dose after 4 hours or as directed by your doctor. Do not take more than 5 milligrams in a 24-hour period.
If you have never taken this medication before and you have risk factors for heart disease (see Precautions), you may be advised to take your first dose in your doctor's office in order to monitor for rare but serious heart problems (e.g., heart attack).
Your dosage is based on your medical condition and response to therapy. Tell your doctor if your condition does not improve or if it worsens.
Overuse of drugs to treat sudden migraine attacks can lead to worsening of headache (medication overuse headache) or rebound headache. Therefore, do not use this medication more often or for longer than prescribed. Tell your doctor if you need to use this medication more often, if the medication is not working as well, or if you have more frequent or worse headaches. Your doctor may need to change your medication and/or add a separate medication to help prevent the headaches.
Amerge oral Side Effects
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.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
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.
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
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.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Amerge oral Interactions
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.
If you also take any ergotamine medication (e.g., dihydroergotamine or methysergide) or any other "triptan" drugs (e.g., zolmitriptan, rizatriptan), you will need to separate your naratriptan dose from your dose of these other medications in order to lessen the chance of serious side effects. Ask you doctor how long you should wait between your doses of these drugs.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy,"St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
Also report the use of drugs which might increase seizure risk (decrease seizure threshold) when combined with naratriptan such as isoniazid (INH), phenothiazines (e.g., thioridazine), theophylline, or tricyclic antidepressants (e.g., amitriptyline), among others. Consult your doctor or pharmacist for details.
