I am 51 and have been taking singulair for a few months. Recently, I have been having trouble concentrating and felt overwhelmed by stress at work and in my home life. I even started seeing a counselor to see what was going on and learn stress and relaxation techniques to help. She said from the sound of it I was mildly depressed. All sounds good, but was getting no better. Last night, I was getting ready for bed and out of the corner of my eye I spotted a sticker on my singulair prescription that said may cause depression or suicidal thoughts. May not be related, but the timing is pretty much the same for me - for switching allergy medications and my feelings of anxiety and depression. I will stop taking singulair and see if that does anything. Maybe the heartburn I have been having will get better too.
