A subdermal implant can always be used during the cycle. However, if unprotected sex has taken place during the last month, another contraceptive method should be applied simultaneously until a pregnancy by a negative pregnancy test or by subsequent onset of menses can be reliably excluded. If the implant is inserted in the first 5 days of the menstrual cycle, no additional contraception is needed. When used outside of this period, for safety’s sake should be applied another method of contraception for at least 3 days. The implant can be used independently of any breastfeeding immediately after a spontaneous or induced abortion or directly after delivery.

Only a progestin implant is available in the US; it is a 4 cm long, size-adjusted single-rod implant, which is inserted subdermally in the groove between the biceps and triceps through a trocar. A skin incision is required. The implant is etonogestrel (a progestin) with an average of 50 ug / day from 12 months. It is an effective contraception for up to 3 years. Before inserting or removing this implant, the doctor must complete a three-hour training at the manufacturer. The currently available implant is bioequivalent to the previously used implant, but is radio-opaque, in order to better locate it at the time of collection. Also, the applicator for insertion can be easier to operate, so that the implant is rarely used too deep. A subdermal implant can always be used during the cycle.

The implant can be used independently of any breastfeeding immediately after a spontaneous or induced abortion or directly after delivery. The most common adverse side effects are similar to those of other comparable progestins (irregular vaginal bleeding, amenorrhea, headache). At least 3 years after the insertion of the implant must be removed; this one incision is required. After removal of the implant, the ovarian function normalized immediately. Other implants are available in other countries.
