**Question:** Drugs contraindicated in pregnancy are all EXCEPT

A. Aspirin
B. Paracetamol
C. Beta-blockers
D. Fluconazole

**Core Concept:** Contraindications in pregnancy refer to medications that should be avoided or used with caution during pregnancy due to potential risks to the developing fetus. Understanding these risks is crucial for healthcare professionals to provide safe and effective care for pregnant patients.

**Why the Correct Answer is Right:** Paracetamol is a safe analgesic and antipyretic drug to use during pregnancy, as it has minimal risk to the fetus. It is considered a Category B drug, meaning that animal studies have not shown any negative effects on pregnancy, and there is no convincing evidence of human risk.

**Why Each Wrong Option is Incorrect:**

A. **Aspirin** is a non-steroidal anti-inflammatory drug (NSAID) and is contraindicated in pregnancy due to the risk of major congenital malformations, premature delivery, and intrauterine growth restriction.

B. **Paracetamol (Option C)** is a safer alternative to aspirin and is classified as a Category B drug.

C. **Beta-blockers** are a class of drugs used to lower blood pressure and heart rate. While some beta-blockers may be used in specific cases, the overall risk-benefit ratio is unfavorable, making them contraindicated in pregnancy.

D. **Fluconazole** is an antifungal drug with potential teratogenic risks, making it contraindicated in pregnancy.

**Clinical Pearl:** When prescribing medications during pregnancy, healthcare professionals should consider the category assigned by the FDA or equivalent system in their respective country. Category B drugs pose minimal risk to the fetus, while other categories (A, B, C, D, X) indicate higher risks. Adequate counseling of pregnant patients about the risks involved is essential, along with providing safer alternative options when available.
