Birth Control Method
Hormonal
Description
Lunelle contains a combination of two hormones, progestin and estrogen, in an injectable form. The shot is injected into a muscle in the arm, buttocks or thigh, once per month.
How It Works
The first injection of Lunelle is usually taken during the first 5 days of a woman's menstrual cycle. Lunelle contains a fraction of the progestin found in Depo-Provera, and less estrogen than is found in birth control pills (the Pill). Both hormones are slowly released during the course of a month. Progestin causes the cervical mucus to become thicker, so sperm cannot reach the egg, and also changes the lining of the uterus so implantation of a fertilized egg cannot occur. Estrogen helps to regulate the menstrual cycle, and helps to keep eggs from being released from the ovaries.
Should You Use It?
Lunelle is a good contraceptive choice for women who like hormonal methods, but have trouble remembering to take a pill each day. It is a good choice for women who like to be discreet about their method of use, as well as for women who are intimate with uninfected, monogamous partners. It is a good alternative for most women who experience nausea while using the Pill.
Effectiveness
The number of pregnancies expected per 100 women per year using Lunelle is less than one.
STI Protection
Lunelle does not protect against the transmission of sexually transmitted infections (STIs), including HIV. If you have a monogamous partner who has tested negative for STIs, or you consistently and correctly use condoms, Lunelle may be a good method for you.
