What should you know about Propecia from Boots?

Finasteride changes the conversion of testosterone into a hormone that can shrink susceptible scalp follicles. It is intended for particular patterns of hair thinning, not every cause of hair loss. A receding hairline or diffuse shedding may also reflect another condition, so the pattern, scalp appearance, medical history and medicines matter.

Buying through a pharmacy does not replace an assessment. Tell the prescriber about liver problems, previous mood symptoms, sexual concerns and all medicines or supplements. Finasteride is not suitable for everyone, and tablets should not be handled by people who are pregnant or may become pregnant if crushed or broken.

Use only the product and schedule supplied for you; do not borrow tablets or combine hair treatments without advice. Keep a baseline record of the hairline and crown in consistent lighting, because gradual change is difficult to judge day to day. Discuss topical minoxidil if finasteride is unsuitable or if a different plan is preferred.

Benefits require continued use and may take time to assess. Report new sexual difficulties, breast changes, testicular pain, allergic symptoms or changes in mood to the prescriber. Do not stop or restart repeatedly without discussing what happened and what alternative is appropriate.

Seek urgent medical help for facial or throat swelling, breathing difficulty, faintness or a rapidly spreading blistering rash. Arrange prompt clinical review for severe low mood, thoughts of self-harm, a breast lump or discharge, or sudden patchy hair loss with scalp pain or scaling.

Ask whether your pattern fits androgenetic alopecia, how progress will be assessed, which side effects need reporting, and whether topical minoxidil or another option fits your health history.
