You should not use this medication if you are allergic to dutasteride (Avodart) or tamsulosin (Flomax).

Do not take dutasteride and tamsulosin if you are also taking alfuzosin (Uroxatral), doxazosin (Cardura), prazosin (Minipress), silodosin (Rapaflo), tamsulosin (Flomax), or terazosin (Hytrin).

Dutasteride and tamsulosin should never be taken by a woman, a child, or a teenager. Dutasteride can be absorbed through the skin, and women or children should not be permitted to handle dutasteride and tamsulosin capsules.

To make sure you can safely take this medication, tell your doctor if you have any of these other conditions:

• low blood pressure;
• high blood pressure (hypertension);
• liver disease;
• severe kidney disease;
• a history of prostate cancer; or
• if you are allergic to sulfa drugs or to finasteride (Propecia, Proscar).

Although dutasteride and tamsulosin is not for use by women, this medication can cause birth defects if a woman is exposed to it during pregnancy. Dutasteride and tamsulosin capsules should not be handled by a woman who is pregnant or who may become pregnant.

If a woman accidentally comes into contact with this medication from a leaking capsule, wash the area with soap and water right away.

Tamsulosin can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using this medication. Do not stop using dutasteride and tamsulosin before surgery unless your surgeon tells you to.

How should I take dutasteride and tamsulosin (Jalyn)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Dutasteride and tamsulosin is usually taken once a day, approximately 30 minutes after a meal. Try to take this medication at the same time each day.

Do not crush, chew, or open a dutasteride and tamsulosin capsule. Swallow it whole. A broken or leaking dutasteride and tamsulosin capsule can irritate your lips, mouth, or throat.

Tamsulosin lowers blood pressure and may cause dizziness or fainting, especially when you first start taking dutasteride and tamsulosin. Call your doctor if you have severe dizziness or feel like you might pass out.

It may take up to 6 months before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

To be sure this medication is helping your condition and not causing harmful effects, your blood may need to be tested often. Your doctor will also test your prostate specific antigen (PSA) to check for prostate cancer. Visit your doctor regularly.

Store at room temperature away from moisture and heat. Do not use a capsule that has been exposed to high heat, which can cause the capsule to change shape or color.
