My son and daughter have taken Singulair off and on several times...

My son and daughter have taken Singulair off and on several times now. My son is on it again because his allergies are acting up because of volcanic fog (vog). Neither of my children have experienced any noticeable side effects from this drug. My daughter, in fact, had no reaction since Singulair doesn't work on all people. I think the fact their pediatrician only placed them on this drug when they needed it and monitored it closely (1 month at a time) may be why they never had any side effects. My son has never been on it for longer than 3 months at a time. My son has done well on this drug and it has amazed me how well it works on his allergies and wheezing. Just because some people have bad reactions doesn't mean the drug needs to be pulled from the market. I certainly don't doubt that people have had bad side effects from this medication though. I am very sensitive to all kinds of medications, even natural herbs and medications that have been around for longer than I have been alive. By just giving me a higher dose of something, I can get numerous side effects like dizziness, mood swings, nausea, stomach problems, and one drug, Ambien, even damaged my sense of smell. My doctors are always giving me the lowest possible doses of medications, and sometimes I am given half of the lowest possible dose. Why? Because I have a sensitive system, and this may be the case with your children or with your own experience. As with any medication, you have to weigh the risks and benefits. Singulair has made a positive difference in my son's life and as long as he is only on it for short periods of times (usually during allergy and/or cold season), I will continue to let him take it.
