What Should I Do If I Miss a Dose of Dutasteride/Tamsulosin?
If you forget to take a dose of dutasteride/tamsulosin, take it later in the day, 30 minutes after your next meal. If it is almost time for your next dose, simply skip your missed dose and continue with your regular dosing schedule. Do not take two doses of this medicine on the same day.
How Does It Work?
Dutasteride, one of the active components of dutasteride/tamsulosin, is a 5-alpha reductase inhibitor. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT). This decreases the amount of DHT in the body. Because DHT is responsible for enlarging the prostate, using dutasteride/tamsulosin to reduce DHT levels can help shrink an enlarged prostate and relieve symptoms of the condition.
Tamsulosin, the other component, belongs to a class of drugs called alpha blockers. It works by blocking alpha-1 receptors. These receptors are found in several places of the body, including the prostate gland. Blocking alpha-1 receptors in the prostate gland helps to relax the muscles of the prostate and the bladder neck (where urine leaves the bladder), helping to relieve enlarged prostate symptoms.
