Package Insert: Information for the Patient

Neomyx 0.5 mg/0.4 mg Hard Capsules

Dutasteride/hydrochloride of tamsulosin

Read this package insert carefully before starting to take this medication, as it contains important information for you.

• Keep this package insert, as you may need to refer to it again.
• If you have any questions, consult your doctor or pharmacist.
• This medication has been prescribed only for you, and you should not give it to others who have the same symptoms as you, as it may harm them.
• If you experience any adverse effects, consult your doctor or pharmacist, even if they are not listed in this package insert. See section 4.

Neomyx (dutasteride/tamsulosin) is used in men to treat an enlarged prostate (benign prostatic hyperplasia) - a non-cancerous growth of the prostate caused by excessive production of a hormone called dihydrotestosterone, in patients already controlled with dutasteride and tamsulosin administered together.

This medication is a combination of two different medications called dutasteride and tamsulosin. Dutasteride belongs to a group of medications called 5-alpha reductase inhibitors and tamsulosin belongs to a group of medications called alpha blockers.

As the prostate enlarges, it may produce urinary problems such as difficulty in urinating and a need to urinate more frequently. It may also cause the urine stream to be smaller and less forceful. If benign prostatic hyperplasia is not treated, there is a risk of complete blockage of the urine flow (acute urinary retention). This requires immediate medical treatment. In some cases, surgery may be necessary to reduce the size of the prostate or remove it.

Dutasteride reduces the production of dihydrotestosterone, which helps to reduce the size of the prostate and alleviate symptoms. This reduces the risk of acute urinary retention and the need for surgery. Tamsulosin acts by relaxing the muscles of the prostate, making urination easier and rapidly improving symptoms.

Do not take Neomyx

• if you are allergic (hypersensitive) to dutasteride, other 5-alpha reductase enzyme inhibitors, tamsulosin, soy, peanuts, or any other component of this medication (listed in section 6).
• if you experience dizziness due to a decrease in blood pressure when changing position (orthostatic hypotension).
• if you have a severe liver disease.
• if you are a woman, child, or adolescent.

Consult your doctorif you think you are in any of these situations.

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

Warnings and precautions

Consult your doctor before starting to take this medication:

• in some clinical studies, the number of patients who experienced heart failure was higher in those who took dutasteride and another medication called an alpha blocker, such as tamsulosin, than in those who took only dutasteride or only an alpha blocker. Heart failure means that your heart is not pumping blood as it should.

• if you have liver problems. If you have any disease that affects your liver, you may need additional checks during your treatment with this medication.

• if you have kidney problems.

• if you are about to undergo cataract surgery, inform your eye doctor that you are taking or have previously taken this medication. Your eye doctor will need to take the necessary precautions to avoid complications during the surgery.

• women, children, and adolescents should avoid contact with broken dutasteride/tamsulosin capsules, as the active ingredient can be absorbed through the skin. If there is any skin contact, 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/tamsulosin. If your partner is pregnant or thinks she may be pregnant, you should avoid exposing her to your semen, as dutasteride may affect the normal development of the male fetus. Dutasteride causes a decrease in sperm count, motility, and semen volume, which may reduce male fertility.

• this medication affects the PSA blood test (prostate-specific antigen) used sometimes to detect prostate cancer. Your doctor may still use this test to detect prostate cancer, but they should be aware of this effect. If you have a blood test to determine your PSA, inform your doctor that you are taking this medication. Men taking this medication should have regular PSA checks.

• in a clinical study conducted in men at high risk of developing prostate cancer, men who took dutasteride presented with more frequent severe prostate cancer than those who did not take dutasteride. The effect of dutasteride on this type of severe prostate cancer is unclear.

• this medication may cause breast enlargement and tenderness. If this causes you discomfort, or if you notice lumps in your breast or nipple discharge, consult your doctor, as these changes may be signs of a serious disease, such as male breast cancer.

Use of Neomyx with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication. This includes any medication purchased without a prescription.

Do not take Neomyx with these medications:

• other alpha blockers(for enlarged prostate or high blood pressure).

Do not take Neomyx with these medications:

• ketoconazole(used to treat fungal infections).

Certain medications may interact with Neomyx, which may increase the risk of adverse effects. Some of these medications are:

• PDE5 inhibitors(used to achieve or maintain an erection) such as vardenafil, sildenafil citrate, and tadalafil
• verapamil or diltiazem(for high blood pressure)
• ritonavir or indinavir(for HIV)
• itraconazole or ketoconazole(for fungal infections)
• nefazodone(an antidepressant)
• cimetidine(for stomach ulcers)
• warfarin(for blood clotting)
• erythromycin(an antibiotic used to treat infections) in combination with paroxetine (an antidepressant) or in combination with terbinafine (used to treat fungal infections)
• terbinafine(for fungal infections)
• diclofenac(used to treat pain and inflammation).

Inform your doctorif you are taking any of these medications.

Taking Neomyx with food and drinks

You should take this medication 30 minutes after the same meal every day.

Do not take Neomyx with alcoholic beverages. Alcohol may worsen the adverse effects of this medication.

Pregnancy, breastfeeding, and fertility

Women who are pregnant (or may be pregnant) should avoid contact with broken capsules. Dutasteride is absorbed through the skin and may affect the normal development of the male fetus. This risk is especially important in the first 16 weeks of pregnancy.

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

Dutasteride/tamsulosin has been shown to decrease sperm count, motility, and semen volume, which may reduce male fertility.

Consult your doctorif a pregnant woman has been in contact with dutasteride/tamsulosin.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medication.
