Migranal Side Effects

Migranal Side Effects : an introduction

As with any medicine, Migranal can cause side effects. Generally, Migranal is tolerated well by most people; however certain people may not be able to safely use Migranal because they have certain medical conditions. In clinical studies, 1.4% of people stopped the drug because of side effects.

The most common reported side effects of Migranal are:

  • Nasal congestion or irritation
  • Altered sense of taste
  • Soreness around the site of nasal spray application
  • Nausea
  • Vomiting
  • Dizziness

Migranal has been reported to rarely cause a very serious (and possibly fatal) lack of blood supply to the hands, feet or brain. Signs include muscle pain, numbness, and coldness, color draining from your skin or blueness in your fingers or extremities. If you experience these symptoms, seek immediate medical attention.
