Side Effects
Comments Sex/Age/

broken sleep, suicidality, disconnected, muscle or joint pain, apathy, dream abnormalities, inability to concentrate, depression

Though my breathing difficulties and chest tightness did improve with this medication, the side effects started right away and worsened quickly each day. I was willing to keep taking it to see if side effects might subside, but on day 4 the muscle and joint pain during and after exercising was excruciating. I apparently just cannot tolerate this drug. .... Read More

social withdrawal, fainting, anger, depression, agitated

My son began taking Singulair when he was 7. We were warned about behavioral issues (ADD like symptoms, insomnia, irritability, etc.) and didn't really notice any change. We recently noticed that my son was hiding it and not taking it (chalk it up to being 12?). Oddly, this surly, angry, frustrated tween I've been dealing with for 2 years went away and my son is back to his silly, funny, not perfect but fun self. He's not as obsessive and introverted (e.g., hooked on video games) and is back out playing basketball with his brother, volunteering to help with his dad, etc. We thought, for a moment, he grew out of being a surly pre-teen. But no...the day we realized he stopped taking it (mid spring-flowering trees, of course), we asked, and he insisted it was an accident and took it in front of us. He fainted at school. Come to find out that fainting is a rare but side effect of singulair. Meanwhile, I add that together with this "normal" kid who is back in our lives and I realize that something happens pre-puberty where kids just don't process it the same. If your kid is on Singulair and you're noticing the "teen angst" -- consider it might be his meds. .... Read More

stomach ache, decreased sex drive, insomnia, sweating, lightheadedness, constipation, weakness, fatigue, diarrhea, muscle cramps or muscle spasm, nausea, headache

It works pretty well for reducing the effects of allergies, but the side effects got in the way of work which isn't acceptable.
