Finasteride Use Is Associated with Higher Odds of Obstructive Sleep Apnea: Results from the US Food and Drug Administration Adverse Events Reporting System

Finasteride can cause sleep disturbances, but these often improve over time. Some users experience side effects like reduced libido and brain fog, while others see hair regrowth and manage side effects by adjusting dosage or switching to topical treatments.

A user reports experiencing insomnia as a side effect of taking finasteride for hair loss, which takes 1 to 2 hours to fall asleep and results in only about 5 hours of sleep per night. They suspect the cause is related to the downregulation of neurosteroids due to finasteride.

A medical student experienced hair loss slowing with Finasteride but developed severe, treatment-resistant insomnia. They tried various medications with little effect, suspecting Post-Finasteride Syndrome, and others suggested the insomnia might be linked to Finasteride's impact on neurosteroids.

Finasteride may cause sleep disturbances, with some users experiencing insomnia. Reducing the dosage, switching brands, or trying Dutasteride might help.

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

Finasteride may affect prostate sensation and size, with some users reporting easier urination. Concerns exist about prostate shrinkage even at lower doses.
