No, Self-medication is not good for health. A little side effect is dangerous to health. We don't know, how many drugs suit our health. I think without Doctor advice, we shouldn't take any type of medicines.
Self medication could be dangerous. It could have some side effects or may lead to some other problems. It is better to consult a doctor for any health issues. But some basic self medication is acceptable with the continued improvement in people's education and general knowledge.
