My 3 years old daughter was on Singulair for 8 months, that was prescribed by her Pedestrian from the Asthma clinic in Canada, Quebec. Lately, some of the symptoms of adverse effects are surfacing in her, including depression, action very emotional, constant having bad dreams (which causes tiredness), crying almost whole day in the daycare, refusing to eat and drink, refusing to join her favorite activities... Her Pedestrian told us there is no side effect on Singulair when she renewed the prescription 2 days ago. Because of my doubt about that, I started research on the web and found out that the early communication was issued by FDA. Of course, I took my daughter off from Singulair right away.
I work in the drug development clinical research field. I know that nothing the FDA or Health Canada will pursue until a lot of cases on adverse events (side effects) reported to them. Please everyone, if you or your child has had developed any side effects on this particular drug (Singulair), please report to FDA at once. It got me so upset is that this drug is constantly and widerly prescribed to children, and the Pedestrians are not caution enough to tell the parents. I definitely do not want to see other children suffer the same symptoms as my daughter had.
