JALYN (dutasteride and tamsulosin hydrochloride) capsules are indicated for the treatment of symptomatic BPH in men with an enlarged prostate.
Dutasteride-containing products, including JALYN, are not approved for the prevention of prostate cancer.
The recommended dosage of JALYN 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 JALYN capsule may result in irritation of the oropharyngeal mucosa.
No data are available with regard to overdosage with JALYN. The following text reflects information available for the individual components.
In volunteer trials, single doses of dutasteride up to 40 mg (80 times the therapeutic dose) for 7 days have been administered without significant safety concerns. In a clinical trial, daily doses of 5 mg (10 times the therapeutic dose) were administered to 60 subjects for 6 months with no additional adverse effects to those seen at therapeutic doses of 0.5 mg.
There is no specific antidote for dutasteride. Therefore, in cases of suspected overdosage symptomatic and supportive treatment should be given as appropriate, taking the long half-life of dutasteride into consideration.
Should overdosage of tamsulosin lead to hypotension [see Warnings and Precautions (5.1), Adverse Reactions (6.1)], support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, then administration of intravenous fluids should be considered. If necessary, vasopressors should then be used and renal function should be monitored and supported as needed. Laboratory data indicate that tamsulosin is 94% to 99% protein bound; therefore, dialysis is unlikely to be of benefit.
Store at 25°C (77°F); excursions permitted 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature]. Capsules may become deformed and/or discolored if kept at high temperatures.
Dutasteride is absorbed through the skin. JALYN capsules should not be handled by women who are pregnant or who could become pregnant because of the potential for absorption of dutasteride and the subsequent potential risk to a developing male fetus [see Warnings and Precautions (5.6)].
