Not to be taken if any of the following apply:
You have Hypersensitivity to the active substance(s) or to any of the excipients or trace residuals in finasteride 1mg tablets. See section 2 and 6.1 of the relevant SmPC.
• You are Under 18 years of age.
• You are Female
• If taking finasteride 5 mg or any other 5α-reductase inhibitor for benign prostatic hyperplasia or any other condition
.•You have severe liver disease.
• You have Chronic medical conditions which may be associated with hair loss - i.e. cancer and chemotherapy.

• You are using any medications associated with hair loss.
• If taking taking medications that would contraindicate the supply of finasteride 1mg tablets (see 2. Product interactions)
Psychiatric disorders
• Treatment is not recommended if you have a history of psychiatric disorders. Mood alterations including depressed mood, depression and, less frequently, suicidal ideation have been reported in patients treated with finasteride 1 mg.
• You should report any signs of depression during treatment. If signs of depression are exhibited, treatment must be discontinued immediately, and seek medical advice.
Partners of pregnant women
• Crushed or broken tablets of finasteride should not be handled by women when they are or may potentially be pregnant because of the possibility of absorption of finasteride and the subsequent potential risk of abnormalities to a male foetus. Finasteride tablets are coated to prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.
• Small amounts of finasteride have been recovered from the semen in subjects receiving finasteride 5 mg/day. It is not known whether a male foetus may be adversely affected if his mother is exposed to the semen of a patient being treated with finasteride. If your sexual partner is or may potentially be pregnant you must wear a condom during sexual intercourse with your partner whilst taking Finasteride.
PSA levels
• In clinical studies with finasteride 1mg in men 18-41 years of age, the mean value of serum prostate-specific antigen (PSA) decreased from 0.7 ng/ml at baseline to 0.5 ng/ml at month 12. If you requires a PSA assay, doubling the PSA level when taking finasteride should be considered before evaluating this test result.
Breast cancer
• Breast cancer has been reported in men taking finasteride 1 mg during the post-marketing period. We advise you to promptly report any changes in your breast tissue such as lumps, pain, gynaecomastia or nipple discharge when taking this medicine.
Fertility
• Long-term data on fertility in humans are lacking, and specific studies in subfertile men have not been conducted. The male patients who were planning to father a child were initially excluded from clinical trials. Although, animal studies did not show relevant negative effects on fertility, spontaneous reports of infertility and /or poor seminal quality were received post-marketing. In some of these reports, patients had other risk factors that might have contributed to infertility. Normalisation or improvement of seminal quality has been reported after discontinuation of finasteride.
Effectiveness of treatment
• Finasteride 1 mg is more effective in the early course of androgenetic alopecia development and is much less effective when alopecia is established.
• Efficacy of treatment in bitemporal recession and end-stage hair loss has not been established.
• Some medicinal products contain lactose-monohydrate. You should not take this medicine if you have rare hereditary problems of galactose intolerance, the total lactase deficiency or glucose-galactose malabsorption.
Dose
One tablet should be taken each day with a glass of water, either before or after meals. Do not crush the tablet before swallowing. If a dosage is missed, do not take two tablets the following day.
Missing a tablet will not affect the results. Remember that hair growth is a slow process and you will not see instant results when taking this form of treatment. It can take between three and six months for results to be seen. Some people may only see a visible difference in hair growth after 12 months.
Finasteride should be taken continuously for as long as you want to prevent hair loss. If you stop taking the medication, you will likely start to experience hair loss once more.

No drug interaction of clinical importance has been identified. [ABPI, 2018; Joint Formulary Committee, 2021]
• Although the risk for finasteride to affect the pharmacokinetics of other drugs is estimated to be small, it is probable that inhibitors and inducers of cytochrome P450 3A4 will affect the plasma concentration of finasteride. However, based on established safety margins, any increase due to concomitant use of such inhibitors is unlikely to be of clinical significance
• Due to lacking data for the concomitant use of finasteride and topical minoxidil in male pattern hair loss the combination is not recommended.
As with any medication, there is a risk of side-effects when taking Finasteride, such as:
- Decreased sex drive
- Problems achieving an erection
- Problems with ejaculation, such as little or no semen
