Pronunciation: /əˌbɔːtɪˈfeɪʃ(ə)nt/ · Part of speech: noun (also used as an adjective) · Field: obstetrics / pharmacology

Definition. An abortifacient is a drug or instrument that provokes an abortion — that is, an agent or device used to bring about the ending of a pregnancy before the fetus is fully developed. The word can also function as an adjective describing something that has this effect (an abortifacient agent).

Two broad types. The dictionary definition reflects that an abortifacient may be either pharmacological or mechanical:

• Drugs — substances that act on the body, for example by altering the hormones that maintain pregnancy or by causing the uterus to contract and expel its contents.
• Instruments — physical devices or surgical tools used to end a pregnancy.

In both cases, the defining feature is the capacity to provoke an abortion.

How drug abortifacients work (in general terms). Pharmacological abortifacients typically act through one of a few mechanisms: interfering with the hormonal support a pregnancy depends on, or stimulating contraction of the uterine muscle so that the uterus empties. The specific medicines, their use, and their regulation vary considerably by country and clinical context, and they are administered only under appropriate medical and legal frameworks.

Related terminology. The verb to abort means to end a pregnancy before full development; the noun abortion names the event or procedure; and abortive can describe something incompletely developed or a treatment that halts a process early. Abortifacient specifically names the agent or instrument that causes the abortion.

Clinical and safety relevance. This is a sensitive area with important medical, legal, and ethical dimensions that differ widely between jurisdictions. The safe and lawful use of any such agent depends entirely on professional medical supervision and on the laws that apply in a given region. Attempting to end a pregnancy without qualified medical care can carry serious health risks. For this reason, questions in this area are properly directed to a qualified healthcare professional working within the applicable legal framework.

Distinction from related terms. A contraceptive prevents pregnancy from beginning and is therefore different in purpose and mechanism from an abortifacient, which acts after a pregnancy has been established. An emmenagogue is a substance that stimulates menstrual flow; some such agents have been historically associated with attempts to induce abortion, but the categories are not identical. “Abortifacient” denotes specifically that which provokes an abortion.

Etymology. From Latin abortus (a miscarriage, from aboriri, “to miscarry”) combined with faciens, “making” or “causing” (from facere, “to make, to do”) — literally, “causing abortion.”
