I started taking singulair about two months ago and as the weeks have gone by my asthma has been better controlled but I am lacking in energy, have aches and pains and have a very fast heartbeat every night. I would love to stay on singulair for the asthma benefits but wondered if anyone else has experienced the rapid heartbeat and general wakefulness at night? I use seretide, an anti histamine, plus numerous meds for other conditions. The only recent change has been the singulair.
Our house has a lot of black mould which I am allergic to and if I try to clean it off the walls I seem to be a lot worse. The building work next door is quiet for now so I have fewer allergens coming from there. As a result of the cleaner air I am planning on giving the singulair a miss for a couple of nights to see if it helps.
I hope someone can shed some light on this problem.
