PCOS - drug/herb interactions?

[Guest guest]

I have a new patient with diagnosed PCOS. She is on 2 grams of metformin per

day, the maximum dose, and is also taking Fersaday iron supplement, and the

progestogen-only contraceptive Cerazette. Her initial prescription includes

Paeonia lactiflora and Glycyrrhiza glabra.

After one week she has stopped the herbal medicine because she says she has

tummy upsets. I would be most grateful for any advice on treating a patient for

PCOS who is on prescribed medication from the GP. I have prepared a letter for

her GP but have not sent it yet. Obviously, I cannot suggest that she reduce her

dose of prescribed medication.

Thanks,

Ruth
