tamsulosin
Summary
Tamsulosin is used to treat benign prostatic hyperplasia, which is an enlarged prostate causing urinary symptoms like difficulty starting urination, weak stream, and frequent urination, especially at night.
Tamsulosin works by blocking alpha-1 receptors in the muscles of the prostate and bladder neck, which relaxes these muscles, improving urine flow and reducing symptoms of an enlarged prostate.
The usual starting dose of Tamsulosin for adults is 0.4 mg once daily, taken about 30 minutes after the same meal each day. If needed, the dose may be increased to 0.8 mg daily.
Common side effects of Tamsulosin include dizziness, headache, and a runny nose, which occur in less than 10% of people taking the medication.
Tamsulosin can cause a sudden drop in blood pressure, leading to dizziness or fainting, especially when standing up quickly. It should not be used if you are allergic to it or have severe liver or kidney problems.
