Indications
Therapeutic Class
Pharmacology
Dosage & Administration
The recommended dosage is 1 capsule (0.5 mg Dutasteride and 0.4 mg Tamsulosin Hydrochloride) taken once daily approximately 30 minutes after the same meal each day.
The capsules should be swallowed whole and not chewed or opened. Contact with the contents of the capsule may result in irritation of the oropharyngeal mucosa.
Interaction
Dutasteride-Tamsulosin combination capsules are used with caution because it-
- Can occur orthostatic hypotension and syncope
- Reduces serum prostate-specific antigen (PSA) concentration by approximately 50%
- Do not use with strong inhibitors of cytochrome P450 (CYP) 3A4 (e.g. Ketoconazole)
- Exercise caution with concomitant use of PDE-5 inhibitors, as this may increase the risk of hypotension
- Drugs that contain Dutasteride, may increase the risk of high-grade prostate cancer
- Women who are pregnant or could become pregnant should not handle due to potential risk to a male fetus
- Advise patients about the possibility and seriousness of priapism
- Patients should not donate blood until 6 months after their last dose
- Intraoperative Floppy Iris Syndrome has been observed during cataract surgery after alpha adrenergic antagonist exposure
- Exercise caution with concomitant use of Warfarin
Contraindications
Side Effects
Pregnancy & Lactation
Tamsulosin & Dutasteride combination is contraindicated for use by women. There have been no studies to investigate the effect of Tamsulosin & Dutasteride combination on pregnancy, lactation and fertility. The following statements reflect the information available from studies with the individual components. Fertility: Dutasteride has been reported to affect semen characteristics (reduction in sperm count, semen volume, and sperm motility) in healthy men. The possibility of reduced male fertility cannot be excluded. Effects of Tamsulosin Hydrochloride on sperm counts or sperm function have not been evaluated.
Pregnancy: As with other 5 alpha reductase inhibitors, Dutasteride inhibits the conversion of testosterone to dihydrotestosterone and may, if administered to a woman carrying a male foetus, inhibit the development of the external genitalia of the foetus. Small amounts of Dutasteride have been recovered from the semen in subjects receiving Dutasteride. It is not known whether a male foetus will be adversely affected if his mother is exposed to the semen of a patient being treated with Dutasteride. As with all 5 alpha reductase inhibitors, when the patient’s partner is or may potentially be pregnant it is recommended that the patient avoids exposure of his partner to semen by use of a condom. Administration of Tamsulosin Hydrochloride to pregnant female rats and rabbits showed no evidence of foetal harm.
Lactation: It is not known whether Tamsulosin or Dutasteride are excreted in human milk.
Precautions & Warnings
Dutasteride-Tamsulosin combination capsules are used with caution because it-
- Can occur orthostatic hypotension and syncope
- Reduces serum prostate-specific antigen (PSA) concentration by approximately 50%
- Do not use with strong inhibitors of cytochrome P450 (CYP) 3A4 (e.g. Ketoconazole)
- Exercise caution with concomitant use of PDE-5 inhibitors, as this may increase the risk of hypotension
- Drugs that contain Dutasteride, may increase the risk of high-grade prostate cancer
- Women who are pregnant or could become pregnant should not handle due to potential risk to a male fetus

- Intraoperative Floppy Iris Syndrome has been observed during cataract surgery after alpha adrenergic antagonist exposure

Use in Special Populations
Renal impairment: The effect of renal impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied. No adjustment in dosage is anticipated for patients with renal impairment.
Hepatic impairment: The effect of hepatic impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied so caution should be used in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the use of Tamsulosin & Dutasteride capsule is contraindicated.
