About finasteride
Tipo di medicinale | 5-alpha reductase inhibitor |
Utilizzato per | Enlargement of the prostate gland in men |
Chiamato anche | Proscar® |
Disponibile come | Compresse |
The prostate gland commonly becomes larger in older men. L'ingrossamento della ghiandola prostatica è anche chiamato iperplasia prostatica benigna (IPB). The prostate gland is situated close to the bladder, so its enlargement can cause problems with passing urine. Common symptoms that are experienced are having to wait before your urine starts to flow, taking longer at the toilet, dribbling urine, and a feeling that your bladder is not quite empty.
Finasteride works by blocking the conversion of the hormone testosterone to the more potent hormone dihydrotestosterone. It does this by blocking an enzyme called 5-alpha reductase. Dihydrotestosterone is partly responsible for making the prostate enlarge. Therefore, a reduced amount of dihydrotestosterone in the prostate causes it to shrink. This helps you to pass urine more easily.
Small doses of finasteride are prescribed for men with hair loss. A completely different brand of finasteride tablet is prescribed for men with this condition. There is more information about the tablets used for this in a medicine leaflet called Finasteride for male pattern baldness.
Before taking finasteride
Torna ai contenutiSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking finasteride it is important that your doctor knows:
Se hai mai avuto una reazione allergica a un medicinale.
Se stai assumendo o utilizzando altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione, così come i medicinali a base di erbe e complementari.

How to take finasteride
Torna ai contenutiBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about finasteride and will provide you with a full list of the side-effects which you may experience from taking it.
Take finasteride exactly as your doctor tells you to. Take one 5 mg tablet each day.
You can take the tablet either before or after a meal, but try to take it at the same time of day each day. This will help you to remember to take your doses regularly.
If you forget to take a dose on time, take it when you remember. If you do not remember until the following day, skip the missed dose. Do not take two doses together to make up for a forgotten dose.
Ottenere il massimo dal tuo trattamento
Torna ai contenutiYour symptoms may start to improve within a few weeks although it can take up to six months for you to notice the full benefit. This is because it takes time for the prostate gland to gradually shrink. Because of this, it is important that you continue to take the tablets regularly, even if you don't feel a benefit straightaway.
Remember to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
Consider reducing or stopping the amount of caffeine you drink (commonly found in tea, coffee and cola) and alcohol. These can make your symptoms worse, so drinking less of these things may benefit you.
If you are a smoker, stopping smoking may significantly improve your symptoms. This is because nicotine irritates the bladder. Ask your doctor for advice on quitting.
Each time you collect a new supply of tablets from your pharmacy, make sure they look to be the same as you have had before. This is because there is a low-dose brand of finasteride tablet available for the treatment of a different condition. If you are unsure that you have the correct tablets, ask your pharmacist to check for you.
Finasteride may cause harm to an unborn baby. Because of this, women who are pregnant should not handle the tablets. Also, small amounts of finasteride will be in your semen while you are taking this medicine, and it is therefore recommended that you use a barrier method of contraception (such as a condom) if your partner could become pregnant. If you need further advice about this, speak with your pharmacist or doctor.
If you are having an operation or any medical treatment, tell the person carrying out the treatment that you are taking finasteride. This is because it can interfere with a blood test used to detect prostate cancer, so you must tell your doctor about taking finasteride if you need this test.

Can finasteride cause problems?
Torna ai contenutiAlong with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with finasteride. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
Common finasteride side-effects (these affect fewer than 1 in 10 men) | Cosa posso fare se sperimento questo? |
Reduced desire to have sex, inability to get an erection, breast tenderness | Se uno di questi diventa problematico, parla con il tuo medico |
Importante: if you develop any pain or lumps in your breast area, or any discharge from your nipples, you should tell your doctor. This is because there have been a few rare reports of breast cancer in men taking 5-alpha reductase inhibitors like finasteride and dutasteride.
Importante: there have been reports of depression in men taking finasteride, and in rare cases, thoughts of self-harming. Patient alert cards are now included with your medicine alerting you to this fact. You should share this information with your family or friends so that they can be alert for any changes in your mood. If you develop any segni della depressione whilst being treated with finasteride, or you have any concerns about your mood, make an appointment to see your doctor.
If you are taking finasteride for prostate problems, you should continue to take your medication until you have spoken with your doctor and agreed a plan.
If you are taking finasteride (Propecia) for male pattern baldness, you should stop taking this medication and make an appointment to see your doctor.
In addition, taking finasteride has caused problems with sexual function in some men, including loss of libido and problems maintaining an erection. This has sometimes continued after stopping treatment. Speak with your doctor if you are concerned about this.
Se si verificano altri sintomi che ritieni possano essere dovuti al medicinale, parla con il tuo medico o farmacista per ulteriori consigli.
