What it is used for
- Helping ovulation in some people who are not ovulating regularly, including some with polycystic ovary syndrome
- Investigation and treatment of certain types of infertility (under specialist care)
How it works
It acts on the brain's hormone signals to encourage the ovaries to develop and release an egg, helping ovulation occur in some people who do not ovulate regularly.
How it is taken
Taken as a tablet for a set number of days early in the menstrual cycle, under medical supervision. Take it exactly as your fertility clinician directs, often with monitoring such as scans or blood tests.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
