Dianette® is licensed for severe acne but increases the risk of VTE- the risk is 1.5 to 2 times higher than for COCs with levonorgestrel and may be similar to the risk with contraceptives containing gestodene , desogestrel or drospirenone. Yasmin is also considered to be a good choice but POPs worsen acne.
Topical retinoids and tetracyclines including oral formulations are contra-indicated in pregnancy. Females of child bearing age must use effective contraception ( oral progestogen-only contraceptives not considred effective ) BNF
