I used to have head ache and vomiting often atleast once a week due to bile(pitham). Before I took any of the painkillers such as saridon, nicip plus and naproxen when I am having extreme headache. Now I am taking cold act tablet if I have that problem. It is giving relief from headache and body pain too and am not getting the issue for the next 1 week. Will there be any side effects for this medication. I couldn't find the exact cause of headaches.
