I hope you reported to the FDA.

Thank you for your comment! You actually opened my eyes! I have been very nauseous and feeling lightheaded like fainting for a week now and the doctors insist this is stress related panic attack. I am still recovering from a sudden alergic asthma crisis and I am on Singulair, Seretide and Spiriva. Reading your message realised that panic attacks and feeling sick could be due to the medicine I am on. Please advise on any the symptoms you had from Singulair.

I would rather breathe. Without Singulair, I would be on inhalers which were more harmful for me. This drug is helpful to the asthmatic. To the common allergy sufferer, take allegra or benadryl
