Review at 3–6 months
Compare standardised photographs and discuss tolerance. Do not judge response after only a few weeks or raise the dose without medical advice.
Side effects
Hormonal and sexual effects
Breast tenderness, reduced libido, sexual symptoms, or menstrual changes may occur. Report a breast lump or nipple discharge promptly.
Mood and allergy symptoms
Low mood or anxiety has been reported with finasteride. Facial swelling, hives, or breathing difficulty can indicate a serious allergic reaction.
04 · When to contact your doctor
Contact your doctor if
- Pregnancy occurs, a period is unexpectedly late, or contraception fails — stop and contact the prescriber promptly
- A breast lump, nipple discharge, severe low mood, or a serious allergic reaction
- Persistent sexual, menstrual, or other effects concern you
Storage
Keep in the original package, away from moisture and direct heat, and out of children's reach. Follow the temperature limit on your pack and do not use it after the expiry date.
What to expect
Hair treatment is gradual. Early shedding can occur, and photographs taken in the same light are more useful than day-to-day checking. The doctor normally reviews tolerance and progress after several months; continue only while the balance of benefit and risk remains appropriate.
