Desomono works to prevent pregnancy by thickening the mucus in your cervix to stop sperm from reaching an egg. It works this way thanks to its active ingredient desogestrel, which is a type of progestogen. This acts in the same way as the natural hormone progesterone. It contains 75 micrograms of desogestrel, which also prevents you from releasing an egg every month.
How long does Desomono last?
Desomono lasts for as long as you take it. There are no breaks between packs, which means it will continue to work for as long as you use it. The contraceptive pill is usually safe to be taken for a long time, as long as there are no medical reasons why you cannot take Desomono.
After you stop taking Desomono, you will begin ovulating again within 48 hours to 4 weeks.
How long does Desomono take to work?
Desomono will start working straight away if you have regular periods and take it on the first day of your period. If you start taking it after day 5 of your period, you will need to use another form of contraception (like condoms) for your first 2 days of taking it.
If you’re on another type of contraception such as the combined pill, transdermal patch, or vaginal ring and start taking Desomono the day after stopping using them it should work straight away, provided you’ve taken them as instructed for the previous 7 days. If you have had a break in between contraception, it may take up to 2 days before you’re protected, so use another form of contraception like condoms during this period if you have sex.
If you’re changing from another progesterone only pill (POP) or mini-pill to Desomono, it will work straight away as long as you don’t take a break in between.
How effective is Desomono
When used correctly, Desomono is over 99% effective. But it is most effective when taken at the same time every day. Sometimes life can get in the way of remembering to take your pill on time, so on average Desomono is 91% effective in preventing pregnancy.
