Lovima is one of the first contraceptive pills to be approved for sale over the counter. It contains the active ingredient desogestrel 75 mcg and is a type of pill called a progestogen-only pill. This means that Lovima can be suitable for women who can’t take pills containing oestrogen. Combined pills that contain oestrogen can’t be taken by some women, for example, women who are very overweight or women who smoke and are aged 35 and over. Lovima can be used by women who are breast-feeding.
If taken correctly, progestogen-only pills are more than 99% effective. However, with typical use (how it’s taken by a lot of women in real life) it’s thought to be about 91% effective. Lovima is taken once daily and there is no need to take a break between packs. The active ingredient is desogestrel, which is a synthetic version of the hormone progesterone. Desogestrel works primarily by stopping ovulation, which means it stops the ovaries from releasing an egg every month. It also thickens the mucus in the neck of the womb to stop sperm from reaching an egg.
Because of the way Lovima works, you may experience irregular vaginal bleeding while taking this medicine. It may be slight staining or heavier bleeding, and some women won’t experience any bleeding at all. After a few months of taking Lovima, the bleeding tends to become less frequent or stop completely. If you think the bleeding is frequent, heavy or prolonged, or you’re worried about the bleeding, contact your doctor or pharmacist for medical advice.
You should tell your pharmacist if you experience any side effects, especially if they’re persistent or severe. Common side effects include mood changes, reduced sex drive, breast pain, nausea, headache, and irregular or no periods. These may affect up to 1 in 10 women.ф
Evidence shows that taking a combined pill (which contains oestrogen) slightly increases the risk of developing breast cancer. This increased risk is being researched for progestogen-only pills, like Lovima, but the evidence of an increased risk is less certain than it is for combined pills. The NHS page on how to check your breasts is a good source of information on what signs to look out for.
There is evidence that combined pills increase the risk of developing blood clots, but there is currently no established link between progestogen-only pills and blood clots.
There have been reports of some ectopic pregnancies in women who are taking desogestrel. You should be aware of the symptoms of an ectopic pregnancy whilst taking this medicine, such as severe pain in the lower stomach. See the NHS information on ectopic pregnancy symptoms for further information.a
