Thanks for posting your query.
You have been prescribed norethisterone
for prolonged periods
). Side effects rarely occur with doses of 15mg daily.Your doctor knows all about side effects and benefits of drug he/she prescribes, all drugs have side effects which occur rarely. Your doctor always evaluates Benefit over Risk. There are many alternatives like hormonal
therapy/OCPs but all of them will have some side effects which may rarely occur.
For further information, contact your doctor.
