You may be interested at these reviews (Write a review):

  • Prednisone relieves anosmia
    Having had anosmia for 15 years now the only thing that ever relieves it, albeit temporarily, is prednisone. I have done 2 surgeries to remove polyps (and won't do it again, waste of time and money - the polyps returned within a year), every herb and other "guaranteed cure" (bogus) on the Internet and the only thing that gives me my smell back is prednisone. Have also done allergy injections, nebulizers, neti-pots, Flonase, etc. None of these things work.
    Being without smell is subtly debilitating. It takes away your drive, your pleasures of life and leads to depression. I wish the medical community would apply as much effort here as they do to the loss of hearing or sight since this is in many ways just as debilitating although in more subtle ways.
  • 1 year old fainting after taking singulair
    My 1 year old girl has asthma like breathing issues when she gets colds.she had been taking singulair and has fainted about 5 times after she mildly hurts herself.(bumps head usually) then screams out forcefully without breathing in then looses consciousness for a few seconds.all incidents after taking singulair.over the course of a few months she is not taking anymore for about 2 weeks but has not passed out recently even after screaming pretty hard .it's hard to say if she has really hurt herself in a similar matter or worse but they are pretty minor incidents that she gets worked up about .
  • Singulair to the rescue
    Antihistamines , even in small amounts, cause my prostate to swell immensely. Several months ago my allergies reached the point I had to take something. I had a physician's sample of 10 mg Singulair, so I took one. To my amazement, I got quick relief from extreme allergies, but my prostate SHRUNK as much as it did on finesteride. Since then I take my usual 2 mg hytrin each morning and my 10 mg Singulair at night and the combo has all but done away with my prostatic hyperplasia. NEVER HEARD OF THIS BEFORE, SO I THOUGHT I WOULD PASS MIT ON.
  • Eczema and birth control-microgestin
    I started getting eczema over the last year and recently decided it may be from the birth control as well, which I started taking @ 2 months before I got the eczema and skin started breaking out...weight gain, etc. I am on singulair, westcort cream, moisture/kenalog, exederm cream, cerevue wash, cetaphil moisturizer, and started using the black soap which is apparently helping. I started a vegetarian diet and eat mainly the same foods daily to monitor anything for allergies. I stopped taking the pill 3 days ago and I am optimistic. I am hoping others have had positive experiences.
  • Nasalcrom caused potential anxiety attacks
    I have a sinus infection that did not go away with a ten day course of Cefuroxime. I went back to the doctor and was subscribed a two week course of Cefuroxime, plus Montelukast for allergy, and NasalCrom for inflamed sinuses. Since I began the NasalCrom, I have been experiencing anxiety attacks. They have been increasing in severity over the last four days of use. The first dose today, day four, may have caused such a severe anxiety attack that I had to leave my job, return home, and function at a very low level with limited stimulus. I have not taken any more doses today and plan to contact my doctor in the morning.
