Singulair and synthroid

Hi,

I just found this site, as I am looking for an explanation for the extreme joint pain that I am having, along with swollen ankles/feet. I have been dealing with some type of chronic contact dermatitis that no one has been able to solve, since last July. I have been on numerous steroids, then on Cyclosporine, for several months, which can play havoc with your kidneys. I also started taking Singulair for the itching, which is one of the few things that has really helped. Since November, I was taking Singulair on and off. But, as I recall, I began taking it daily since around late January. Around late February, I began having joint pain, which still continues, and lately, is becoming excruciating! When it first began, I blamed it on the Cyclosporine and kidney breakdown. But, since I have been off that, the pain has continued to worsen. Then I thought it may have something to do with the Doxepin, which I also take at night for the itching. I stopped taking that two nights ago, but the pain continues to worsen.

Now, from what I am reading, these blogs make me believe it could be the Singulair. Can anyone tell me how long it takes for the pain to go away once you stop taking the Singulair????? I will gladly stop taking it if this pain will go away. In fact I will be thrilled, because I was suppose to begin testing next weak for possible Lupus, because it doesn't seem that the Physicians who prescribe Singulair, are well aware of these issues.

I would appreciate anyone who can give information as to how long it takes for the side effects to subside. Thank you!!!

Our son started taking Singulair when he was 2 for severe allergic rhinitis and cough variant asthma (in addition to Zyrtec, which didn’t control all of his symptoms). He is 5 now. For the last three years, he has been an increasingly violent, difficult, defiant, argumentative, volatile child who has intense mood swings--one minute he’s laughing uncontrollably, the next he’s weeping over nothing. His doctor and therapist recommended that we see a psychiatrist to have him evaluated for bipolar disorder, which used to be unknown in children. Because he has such chronic sleep problems, the doctor also suggested we take him off Singulair (and increase his Zyrtec dose) to see if it improved his sleep issues. Within a week, he was sleeping much better and was a calmer, happier, gentler boy. He suddenly could take “no” for an answer without flipping out and trying to hurt me. We thought that we were just in an unusual, calm window that would shift either to mania or intense sadness or both, any minute. We also thought that his behavior change might be due to sleeping better. We were enjoying the rare reprieve. Over the last weekend, his springtime allergies really flared up. We gave him Singulair on Monday and by noon, he was completely out of control. I had to strap him into his car seat at one point to keep him from hurting either me or himself. It finally occurred to me that Singulair might be causing his “bipolar” disorder. Of course, we stopped the Singulair. After two days he was a new boy. Yesterday, I Googled “Singulair bipolar children” and got a few hits. I am stunned to read how similar other families’ experiences have been to ours and I feel sick that we gave this drug to our child for three years.
