Which statement about adverse effects of finasteride is accurate?

• A. Finasteride may cause sexual side effects and fetal risks; minoxidil may cause scalp irritation and unwanted hair growth beyond treated areas
• B. Finasteride has no sexual side effects; minoxidil has no scalp irritation
• C. Both drugs are free of adverse effects
• D. Finasteride cures baldness instantly

Answer: (A)

Understanding adverse effects of hair loss medicines helps you weigh safety alongside effectiveness. Finasteride is a 5-alpha-reductase inhibitor that lowers dihydrotestosterone (DHT). Lowering DHT can help with hair loss, but it can also cause sexual side effects such as reduced libido, erectile dysfunction, and ejaculation problems. There's also a fetal risk concern because exposure to finasteride during pregnancy can affect male fetal development, so pregnant women should avoid handling the medication if tablets are broken or crushed. Minoxidil, used topically for hair results, can irritate the scalp in some people, causing local reactions like redness or itching. If it gets absorbed systemically in larger amounts, it can stimulate hair growth in areas beyond the treated scalp, leading to unwanted or excessive hair in those regions. So the accurate statement is that finasteride may cause sexual side effects and fetal risks, while minoxidil may cause scalp irritation and unwanted hair growth beyond treated areas. The idea that there are no adverse effects, or that the cure is instant, doesn’t fit what’s known about these drugs.
