The progestogen-only pill offers effective contraception with fewer side effects, but requires strict adherence and doesn't protect against STIs.
Contraceptive pill types and benefits
The contraceptive pill is a hormone-based medication sold in blister packs. It prevents pregnancy and may offer additional benefits, such as reducing acne, making periods lighter and more regular, or decreasing menstrual cramps. Two main types of contraceptive pills
There are two types of contraceptive pills: combined pills, which contain both estrogen and progestogen, and progestogen-only pills, which contain only a synthetic progestogen hormone. Progestogen-only pills do not contain estrogen. Mechanism of progestogen-only pills
Progestogen-only pills work by modifying the endometrium (the lining of the uterus) to prevent implantation, altering cervical mucus to block sperm, and possibly preventing ovulation. Their effectiveness depends on the specific progestogen used and the dosage. Types of progestogen-only pills
There are three types of progestogen-only pills, each differing by the progestogen used: levonorgestrel, desogestrel, and drospirenone. Levonorgestrel is the oldest and has a smaller missed dose window of three hours, while drospirenone, the most recent, has a 24-hour window. How to use progestogen-only pills
Progestogen-only pills are taken daily, starting on the first day of menstruation, without interruption. The blister pack contains 24 active tablets and four placebo tablets. They should be taken at the same time each day to maintain effectiveness. Who can use progestogen-only pills
Progestogen-only pills are often recommended for women who cannot tolerate estrogen or have vascular conditions such as diabetes, migraines, or phlebitis. A healthcare provider can help choose the most suitable contraceptive based on medical history and personal factors. Effectiveness and limitations
Progestogen-only pills are highly effective in preventing pregnancy when started on the first day of menstruation. However, they do not protect against sexually transmitted infections (STIs). Using a condom alongside the pill is recommended for protection against STIs. Cost and availability
Progestogen-only pills are available by prescription in pharmacies. Some are partially reimbursed by the Social Security, while others are not. Prices vary between 1.88 and 14 euros per box. In some countries, they are available without a prescription, but this may reduce opportunities for regular health check-ups. Missed dose guidelines
If a dose is missed within three hours, it should be taken as soon as possible and the schedule continued. If missed for longer, emergency contraception may be needed, depending on the type of pill and the timing of sexual activity. Weight gain and other concerns
No studies have found a direct link between contraceptive pill use and significant weight gain. Any weight changes are typically minimal, if present at all.
