2. What you need to know before you take Dutasteride Viatris

Do not take Dutasteride Viatris

• If you are allergic to dutasteride, other 5-alpha reductase inhibitors, soy, peanuts, or any of the other ingredients of this medicine (listed in section 6).
• If you have severe liver disease.

If you think you may be in one of these situations, do not takethis medicine until you have consulted your doctor.

This medicine is for men only. It must not be taken by women, children, or adolescents.

Warnings and precautions

Talk to your doctor before taking Dutasteride Viatris.

- In some clinical studies, there were more patients taking dutasteride and another medicine called an alpha-blocker, such as tamsulosin, who experienced heart failure compared to patients who took only dutasteride or only an alpha-blocker. Heart failure means that your heart does not pump blood as it should.

- Make sure your doctor knows if you have liver problems. You may need some additional checks during your treatment with Dutasteride Viatris if you have any liver disease.

• Women, children, and adolescents must avoid contact with leaking Dutasteride Viatris capsules, as the active ingredient can be absorbed through the skin. If there is any contact with the skin, the affected area should be washed immediately with water and soap.
• Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking dutasteride. If your partner is pregnant or thinks she may be pregnant, she should avoid exposure to your semen because dutasteride may affect the normal development of a male baby.

Dutasteride has been shown to decrease sperm count, sperm motility, and semen volume. This may reduce fertility.

• Dutasteride affects the blood test for PSA (prostate-specific antigen) used to detect prostate cancer. Your doctor may still use this test to detect prostate cancer, but must be aware of this effect. If you have a blood test for PSA, tell your doctor that you are taking Dutasteride Viatris. Men taking Dutasteride Viatris should have regular PSA tests.

In a clinical study in men at high risk of prostate cancer, men who took dutasteride were more likely to have a type of prostate cancer that was more serious than those who did not take dutasteride. The effect of dutasteride on these more serious types of prostate cancer is not clear.

• Dutasteride Viatris may cause breast tenderness or enlargement. If this causes you discomfort, or if you notice lumps or nipple discharge, talk to your doctor, as these changes can be signs of a serious disease, such as breast cancer.

Talk to your doctor or pharmacist if you have any questions about taking Dutasteride Viatris.

Mood changes and depression

Depressed mood, depression, and, less frequently, suicidal thoughts have been reported in patients treated with another medicine in the same therapeutic group (oral 5-alpha-reductase inhibitor). If you experience any of these symptoms, contact your doctor for additional medical advice as soon as possible.

Taking Dutasteride Viatris with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Certain medicines may interact with Dutasteride Viatris, which can increase the risk of you experiencing side effects. Some of these medicines are:

• verapamil or diltiazem (for high blood pressure)
• ritonavir or indinavir (for HIV)
• itraconazole or ketoconazole (for fungal infections)
• nefazodone (an antidepressant)
• other alpha-blockers (for enlarged prostate or high blood pressure).

Tell your doctorif you are taking any of these medicines. It may be necessary to reduce the dose of Dutasteride Viatris.

Taking Dutasteride Viatris with food and drink

Dutasteride Viatris can be taken with or without food.

Pregnancy, breast-feeding, and fertility

Pregnant women (or women who may be pregnant) must avoid contact with leaking capsules. Dutasteride is absorbed through the skin and may affect the normal development of a male baby. This risk is especially important during the first 16 weeks of pregnancy.

Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking dutasteride. If your partner is pregnant or thinks she may be pregnant, she should avoid exposure to your semen.

Dutasteride has been shown to decrease sperm count, sperm motility, and semen volume. This may reduce fertility.
