**Question:** True about household emetics are all, except: DNB 08

A. They are effective only in small doses
B. They require a prescription
C. They are used to treat poisoning
D. They are safe for long-term use

**Core Concept:** Emetics are substances that induce vomiting when administered, either voluntarily or involuntarily, and are used for therapeutic or diagnostic purposes. They can be divided into two categories: pharmacological emetics (pharmacologically induced vomiting) and physical emetics (induced by external factors like mechanical pressure, cold stimuli). True about household emetics refers to the properties of pharmacological emetics.

**Why the Correct Answer is Right:** The correct answer, D, states that household emetics are not safe for long-term use. This is true, as repeated vomiting can lead to complications such as electrolyte imbalances, malnutrition, dehydration, and damage to the gastrointestinal tract.

**Why Each Wrong Option is Incorrect:**

A. False: Small doses of pharmacological emetics can be effective in inducing vomiting for therapeutic purposes, such as removing foreign bodies or treating poisoning.
B. False: In most cases, household emetics do not require a prescription, as they are available over-the-counter. However, some may need a prescription in certain jurisdictions or for specific indications.
C. False: Household emetics are not typically used to treat poisoning; instead, they are used for therapeutic purposes like removing foreign bodies or treating poisoning, but not specifically for poisoning treatment.

**Clinical Pearl:** When using household emetics, it is crucial to consider potential complications and consult a healthcare professional if unsure about dosage, frequency, or indications. Emesis should be reserved for therapeutic indications, and prompt medical evaluation is advised in case of poisoning or severe ingestion.
