Patient Medication Information: uses, side effects, how to take - Ratio-Tamsulosin
ABOUT THIS MEDICATION
What this medication is used for:
- ratio-TAMSULOSIN is for use by men only.
Your physician has prescribed ratio-TAMSULOSIN because you
have a medical condition called benign prostatic hyperplasia or BPH. This occurs only in men.
What it does:
ratio-TAMSULOSIN acts by relaxing muscles in the prostate and bladder neck at the site of the obstruction, resulting in improved urine flow, and reduced BPH symptoms.
What is BPH? BPH is an enlargement of the prostate gland. After age 50, most men develop enlarged prostates. The prostate is located below the bladder. As the prostate enlarges, it may slowly restrict the flow of urine. This can lead to symptoms such as:
- having a weak urinary system;
a sensation of not emptying your bladder completely after you
finish urinating;
- pushing or straining to begin urination;
- stopping and starting again several times when urinating;
- urinating again less than 2 hours after you finish urinating;
- finding it difficult to postpone urination;
- frequent sleep interruption caused by a need to urinate.

You should not use ratio-TAMSULOSIN if you are allergic (hypersensitive) to tamsulosin or any of the other ingredients in ratio- TAMSULOSIN. Hypersensitivity may present as sudden local swelling of the soft tissues of the body (e.g. the throat or tongue), difficult breathing and/or itching and rash (angioedema).
