Hello.Thanks for your query. Homonal therapy is indicated for acne resistant to treatment by other methods and is of benefit in controlling the acne by the effects of the component hormones on their receptors.Such women experience increased acne lesions on the lower one-third of the face, including the jawline and upper neck, and a tendency for the development of painful nodules. A tendency toward peri-menstrual flares or an exacerbation of acne in the one to two weeks prior to menstruation also indicates a hormonal influence. You should visit a dermatologist to switch over to other methods of acne control before you stop the pill.Any agent for acne control requires 4-6 weeks to start showing an effect, hence starting prior is necessary. It is not necessary to wean off these pills; nor there are standardized regimens to do so.If you have to stop taking them, you simply have to stop that. Hope this is helpful,take care!
