<s>[INST] I am prescribed by doctor to take Etova- p 400 1tab twice a day for 7 days for pain in muscles in buttock on both side of the anus. There is no pain in the lower tip of vertibra. Should I use it for relief or their is danger of its side effects as I find in the website? Please advise. [/INST] Hi Every medicine has some side effects- what has to be decided is whether the side effects are more or the problem is more. In your case Taking Etova -P for a period of 7 days is not likely to cause any major side effects and it will relieve your pain. So go ahead and take the medicine as prescribed </s>
