| Pharmacokinetics | IUDs do not have a pharmacokinetic profile in the traditional sense. They work by preventing fertilization or implantation. Their mechanism of action is based on physical barrier and, in some cases, hormonal release. |
| suggested dosage | N/A. IUDs are a one-time placement, not a daily/regular dosage. Different IUDs have varying durations of effectiveness. |
| indications | | 1 | Contraception | | 2 | Treatment of menorrhagia (heavy bleeding) in some cases | | 3 | Possible use in certain types of pelvic pain | | 4 | Prevention of ectopic pregnancy |
|
| Safety in pregnancy | IUDs are *contraindicated* in pregnancy. Their presence during pregnancy is dangerous to the fetus and would need to be removed if discovered. |
| Safety in breastfeeding | Generally safe for breastfeeding mothers. A woman's doctor can recommend an appropriate IUD for her circumstances. |
| side effects | | 1 | Initial cramping and/or bleeding (first few weeks to months) | | 2 | Increased menstrual bleeding or cramping (in some cases) | | 3 | Infection risk (rare, but important) | | 4 | Expulsion (rare, but needs follow-up) | | 5 | Perforation (rare, but severe complication) | | 6 | Pelvic pain | | 7 | Spotting or breakthrough bleeding |
