Patient's Query
Hello doctor,
I want to know what the horizontal lines on my fingertips are. They appeared within a couple months, along with more lines on my hands than ever before.
Hi,
Welcome to icliniq.com.
I have seen images attached here (attachment removed to protect patient identity). It does not signify any health issue. It seems to be normal flexor creases. The Finasteride drug that you were taking can lead to the following side effects:
For further investigations, I suggest you undergo the following tests:

Patient's Query
Hello doctor.
Thank you for the reply.
I would have agreed with you regarding normal flexor creases, except for the fact that these appeared within a few months and are now present on every fingertip.
I am concerned that Propecia may have disrupted my hormonal system in some way, possibly affecting my thyroid function.
There have been reports of some people developing elevated reverse T3 levels after taking Propecia (Finasteride). In addition to routine blood work, I am planning to have a comprehensive thyroid panel done, including a reverse T3 test.
Please help.
Hi,
Welcome back to icliniq.com.
I appreciate your attention to your health.
You are essentially asking whether these skin changes could represent a cutaneous manifestation of thyroid disease.
In hyperthyroidism, the skin is often warm, moist, and sometimes flushed or red. Facial flushing can occur. Therefore, the changes you describe do not fit the typical pattern seen in hyperthyroidism.
In hypothyroidism, the skin may become excessively dry, rough, or scaly. However, increased fingertip creases are not usually considered a characteristic feature.
Propecia (Finasteride) works by inhibiting the 5-alpha reductase enzyme and is commonly used for conditions such as prostate enlargement and hair loss. It is not generally known to have significant effects on thyroid function.
Regarding dermatological side effects, Finasteride may occasionally cause skin rashes, itching, allergic reactions, urticaria, or vasculitis-like reactions.
For your peace of mind, if you are concerned about a possible association between Finasteride and thyroid function, it would be reasonable to undergo thyroid testing, including:
Free T4 (free thyroxine).
Reverse T3 (reverse triiodothyronine).
Free T3 (free triiodothyronine).
Serum TSH (thyroid-stimulating hormone).
I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.
Thank you.
