A minor surgical procedure is necessary for removal. Menstrual irregularities are common.  Other adverse effects including headache, breast tenderness and moodiness are less common.  Irregular bleeding may be improved with NSAIDS or a short-term course of low-dose combined oral contraceptives or estrogen.

Another FDA-approved implant is the 2-rod levonorgestrel system, termed Norplant II or Jadelle. Each rod is 4.4 cm long and contains a cured homogenous mixture of the drug and a polydimethylsiloxane elastomer covered by silicone tubing. Norplant II is approved for 5 years of use. Studies have shown Norplant II to have release rates, pregnancy rates, and adverse effect profiles similar to Norplant. At this time, Norplant II is not currently being marketed in the United States. Jadelle is currently available in both developed and developing nations around the world.
