Q: I am a 24 years old male having a lot of pimples on my back. How to get rid of them?

A:Mild acne can be treated successfully with topical gels which contain clindamycin, benzoyl peroxide and retinoids, usually given in combination. Stubborn cases require oral antibiotics. Very bad cases or those who relapse frequently or who are poor responders may need oral isotretinoin. Proper clinical assessment is required before a particular medicine is selected.
