Mechanism

The contraceptive implant works by releasing progestogen, which interferes with ovulation, thickens the cervical mucus and thins the lining of the uterus.

Features

The contraceptive implant is a small flexible rod that is inserted subdermally by a healthcare professional.

• It works for 3 years but can be taken out sooner. When removed, fertility returns to normal quickly.
• Does not require daily adherence to a medication regimen.
• Periods may stop, become irregular or last longer. Acne may occur or worsen.
• It is important to warn the patient that a small procedure is required to fit and remove the implant, and a local anaesthetic should be used in order to fit the device
• There may be some tenderness, bruising and swelling at the site of insertion.
