<s>[INST] I have started taking 2mg Coversyl and low dose asprin daily.  Since then I have not had a firm erection. Is the medicine responsible?  I'm 63 years old and over weight (40% body fat) but that has never effected me before. This problem is current with the start of the medication. [/INST] Helloyes, Coversyl can cause ED. I suggest you to start physical exercise and eat healthy food with adequate proteins . It should be helped in 4-6 weeks or ask your doctor to change the medicine.DR SAATIISH JHUNTRRAA </s>
