What is Tamsulosin?

Tamsulosin (active ingredient: tamsulosin) is a type of medicine called an alpha blocker. Tamsulosin works by blocking alpha receptors that are found in the muscle in the prostate gland. This action causes the muscle in the prostate to relax, which relieves pressure on the urethra and allows urine to flow freely past the prostate gland. This makes it easier to pass urine. To order Tamsulosin online, go to a Dokteronline.com partner pharmacy. Tamsulosin is a prescription-only medicine that can be obtained through an online consultation. Once a prescription is issued, it is sent to one of our affiliated pharmacies for immediate shipment.

What is Tamsulosin used for?

Tamsulosin is used to relieve the urinary symptoms of an enlarged prostate gland (benign prostatic hyperplasia or BPH). The prostate is a gland found only in men. It often enlarges with advancing age, pressing on the urethra and obstructing the flow of urine from the bladder. This can cause various urinary symptoms, such as difficulty passing urine, dribbling of urine after urinating, and needing to pass urine more often or urgently. Tamsulosin relaxes the smooth muscle in the prostate and urethra. This makes it easier to pass urine and empty the bladder, which in turn, reduces the urinary symptoms.

How to use Tamsulosin

One Tamsulosin capsule should be taken once a day, preferably after breakfast. Swallow the capsule whole with plenty of liquid. If you have forgotten to take a dose, you may take the missed dose unless it is almost time for your next scheduled dose. Never take a double dose to make up for the forgotten one.
