There are a number of side effects with naratriptan that you should report to your healthcare provider. These include, but are not limited to:
- Severe chest pain or tightness (see Amerge and Heart Problems)
- Shortness of breath
- Sudden, severe abdominal pain (or stomach pain)
- Bloody diarrhea
- Changes in vision, including loss of vision
- Dizziness, lightheadedness, or fainting
- Signs of an allergic reaction, including unexplained skin rashes, itching, hives, wheezing or shortness of breath, and unexplained swelling.
Taking naratriptan with certain antidepressants can increase your risk of a group of dangerous symptoms called serotonin syndrome. Contact your healthcare provider immediately if you have the following symptoms of serotonin syndrome:
