Overview
Microval was a progestogen-only 'minipill'. Like other minipills, it contained just one hormone - progestogen - and was taken 365 days of the year.
The minipill
The minipill was a welcome innovation for women who couldn’t take the combined pill – including diabetics, migraine-sufferers, and breastfeeding mothers.
When taken correctly, the minipill is nearly as effective as the combined pill, with its dual dose of progestogen and oestrogen.
