Precautions and Warnings With Naratriptan

Some Precautions and Warnings With Naratriptan

Some naratriptan warnings and precautions to be aware of include the following:
 
  • Naratriptan has been reported to increase the risk of a heart attack or a life-threatening change in a person's heart rhythm (arrhythmia). You should not take naratriptan if you have heart disease or a history of a heart attack or chest pain (see Amerge and Heart Problems for more information)
If you have risk factors for heart disease (see Heart Disease Risk Factors), it is also strongly recommended that you take your first dose of naratriptan in your healthcare provider's office so he or she can monitor your heart. You should also have your heart checked periodically while taking naratriptan.
  • In some cases, a stroke or transient ischemic attack ("mini stroke") can be misdiagnosed as a migraine. Your healthcare provider should make sure you are not having a stroke, especially if you have never had migraines in the past (see Stroke Symptoms for more information on the symptoms of a stroke).
     
  • If you have chest pain or tightness in the jaw or neck after taking naratriptan, contact your healthcare provider immediately. These side effects are fairly common with naratriptan and are not usually serious. However, your healthcare provider may need to make sure you are not having heart problems.
     
  • Medications like naratriptan can cause blood vessels to spasm, including in the arms, legs, or colon (large intestine). This can cause a decrease in blood flow to these areas. Symptoms will vary based on the location. For example, a spasm in the colon can lead to severe abdominal pain (or stomach pain) or bloody diarrhea.
     
  • Taking naratriptan with certain antidepressants, including selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs), can increase your risk of a dangerous group of symptoms called serotonin syndrome. Do not use naratriptan with depression medications without first discussing it with your healthcare provider. Contact your healthcare provider immediately if you have any possible symptoms of serotonin syndrome, including:

 

    • Confusion
    • Seeing or hearing things that are not really there (hallucinations)
    • A fast heartbeat (tachycardia)
    • Feeling faint
    • Fever
    • Sweating
    • Muscle spasms
    • Difficulty walking
    • Diarrhea. 

 

  • Naratriptan can cause an increase in blood pressure. You should not take naratriptan if you have untreated high blood pressure (hypertension).
     
  • Naratriptan is considered a pregnancy Category C medication. This means that naratriptan may not be safe for use during pregnancy. Talk to your healthcare provider before using naratriptan if you are pregnant (see Amerge and Pregnancy for more information).
     
  • It is not known if naratriptan passes through breast milk. Therefore, if you are breastfeeding or plan to start, be sure to talk with your healthcare provider about this.
     
  • Tell your healthcare provider if you have liver problems (including liver failure or cirrhosis) before taking naratriptan. Naratriptan is removed from the body through the liver. Therefore, people with severe liver problems should not take naratriptan.
     
  • Naratriptan can interact with certain medications (see Drug Interactions With Naratriptan).
