Like any medicines, Imigran Nasal Spray can cause side effects, but not everybody may experience them. Some symptoms may be caused by the migraine itself.
Common side effects of Imigran Nasal Spray include pain, heaviness, pressure or tightness in the chest, throat or other parts of the body, or unusual sensations, including numbness, tingling and warmth or cold. These effects may be intense but generally pass quickly. Some people also experience nausea, dry mouth and drowsiness. These side effects are usually mild and improve on their own.
