What adverse effect is commonly associated with cyclosporine treatment?

The correct choice is that hirsutism, or excessive hair growth, is a notable adverse effect associated with cyclosporine treatment. Hirsutism occurs due to the drug's influence on hormonal balance and its potential effects on hair follicle activity. Cyclosporine is an immunosuppressant commonly used in transplant patients and for autoimmune disorders. While it can cause various side effects, the hormonal activity it influences can lead to hirsutism, making it a recognizable outcome for patients undergoing this treatment.

While nephrotoxicity is also a known concern with cyclosporine—reflecting its potential for causing kidney damage—it is not the most recognized side effect compared to hirsutism in some patient populations. Similarly, infections are a significant risk due to immune suppression. Hyperlipidemia may occur, but it is considered less prominent than hirsutism in patients treated with this medication. Given the context of assessing the most commonly reported side effect, hirsutism stands out distinctly in relation to cyclosporine.
