I am a 55 year old male, active and mostly physically fit. I have been taking Singulair for 10 years and my asthma has been reasonably well controlled most of the time. Already after 6 months of taking the drug I noticed a tendency of easy bruising, fragile skin and bleeding but my doctor never thought this had anything to do with Singulair but rather because of my prolonged usage of steroid creams for my eczema. However, the bruising never seemed to coincide with the areas of my body where I had mainly used steroid cream. About three weeks ago I decided to stop taking Singulair and I also discovered that bruising and bleeding are mentioned as possible side effects of the drug.
After I stopped taking Singulair I have not had any further bruises and my skin seems stronger.
