Final answer:
Acne medications, antibiotics, some antidepressants, and synthetic estrogen can function as teratogens during pregnancy.
Step-by-step explanation:
Teratogens are compounds that can permanently deform the function or structure of a developing embryo or fetus. In the case of prescription drugs, several types can function as teratogens including:
Acne medications: Certain acne medications, such as isotretinoin (Accutane), have been known to cause various abnormalities.
Antibiotics: Some antibiotics, like tetracycline, can lead to dental and skeletal abnormalities in the developing fetus.
Some antidepressants: Certain antidepressants like selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased risk of birth defects.
Synthetic estrogen: High doses of synthetic estrogen, such as those found in hormone replacement therapy, can increase the risk of birth defects.
