1. What Penester is and what it is used for

Finasteride, the active substance of Penester, is a 5-alpha reductase inhibitor, an enzyme that converts testosterone (male sex hormone) into a more potent dihydrotestosterone (DHT). Penester reduces the volume of the prostate gland.
Penester is used to treat a condition called benign prostatic hyperplasia. The prostate gland, located in the area of the initial fragment of the urethra, has enlarged.
As a result of the enlargement of the gland, difficulties in urinating have appeared.
The medicine is indicated for the treatment of benign prostatic hyperplasia (BPH) to:
relieve symptoms,
reduce the risk of acute urinary retention,
reduce the risk of needing a transurethral resection of the prostate (TURP) and (or) prostatectomy (surgical removal of the prostate gland),
reduce the enlarged prostate gland, improve urine flow, and reduce symptoms associated with prostate enlargement.

2. Important information before taking Penester

Penester is not indicated for use in women or children.

When not to take Penester

if you are allergic to the active substance or any of the other ingredients of this medicine (listed in section 6).
in women who are pregnant or breastfeeding (see below).

Warnings and precautions

Before starting treatment with Penester, discuss it with your doctor.
Benign prostatic hyperplasia is a condition that develops over a long period. In some patients, relief of symptoms occurs shortly after starting therapy. However, it may be necessary to take the medicine for at least 6 months to achieve significant improvement. Regardless of whether symptoms improve, taking Penester may reduce the risk of acute urinary retention and delay the need for surgical treatment. To monitor the progress of treatment, the patient should remain under constant medical supervision.
Benign prostatic hyperplasia is not a tumor, nor does it lead to the development of a tumor, but these conditions can occur simultaneously. Only a doctor can properly assess the symptoms and their likely cause.
Tell your doctor about all diseases that are currently present or have occurred in the past and about any allergies.
The medicine affects the results of PSA (prostate-specific antigen) blood tests. Patients undergoing PSA testing should inform their doctor about taking Penester.
Penester is intended for use only in men for the treatment of benign prostatic hyperplasia.

Mood changes and depression

In patients taking Penester, mood changes, such as depressive mood, and depression, as well as suicidal thoughts, have been reported. If any of these symptoms occur, seek medical advice immediately.

Children

Penester is not indicated for use in children.

Penester and other medicines

Tell your doctor about all medicines you are currently taking or plan to take. Penester usually does not affect the action of other medicines taken.

Penester with food and drink

The medicine can be taken with or without food.

Pregnancy and breastfeeding

Pregnancy
Women who are pregnant or breastfeeding should not take Penester. Pregnant or breastfeeding women, or those who suspect they may be pregnant, should not even touch broken or crushed Penester tablets due to the possible absorption of finasteride and the associated risk to the male fetus.
If the active substance of the medicine penetrates the body (after oral administration or through skin contact) of a pregnant woman carrying a male fetus, it may cause developmental disorders of the genital organs in the fetus. In case of contact between a pregnant woman and the active substance of Penester, inform your doctor. Penester tablets are film-coated, which prevents direct contact with the active substance, provided that the tablets are not damaged.
If your partner is pregnant or may be pregnant, it is recommended that you minimize your partner's exposure to semen (e.g., by using condoms).
Your doctor can provide more information on this.
Breastfeeding
It is not known whether finasteride passes into human milk.

Driving and using machines

There is no data indicating that the medicine impairs the ability to drive or operate machines.

If you have previously been diagnosed with intolerance to some sugars, you should consult your doctor before taking this medicine.
