The standard treatment for acne is a course of oral antibiotics such as Oxytetracycline 250mg twice daily and a topical retinoid such as Differin (adapalene).
Female acne patients will also benefit from taking a combined oral contraceptive pill such as Yasmin or Diane35. The oestrogen in these pills blocks the action of acne-causing hormones on the skin. These are commonly prescribed to teenage girls to clear acne, even if they are not sexually active.
Avoid progesterone-only pills (mini-pills) and the depot shot, as these can make acne worse.
