Tamsulosin
(Flomax, United States and Canada)

More drugs used for BPH.

Use:

Tamsulosin or Flomax is used for benign prostatic hypertrophy.

How It Works:

Tamsulosin or Flomax is an alpha blocker meaning that it blocks a specific part of the nervous system - the alpha part. This blockage reduces the nervous system messages sent to muscles in the urinary tract specifically the bladder neck and the prostate. This results in relaxation of these areas and enables voiding.

Side Effects:

Tamsulosin or Flomax is generally well tolerated and side effects are not common. However, Tamsulosin or Flomax can cause a drop in blood pressure resulting in syncope or fainting. Other reported side effects include dizziness, headache, nasal congestion, and heart palpitations.

Cautions for People:

Because Tamsulosin or Flomax has the ability to affect blood pressure control, it must be used with caution by people who have low blood pressure or who are taking blood pressure medication. Older people are more at risk for blood pressure problems and should be closely followed. Not all men with benign prostatic hypertrophy or BPH are suitable candidates for the drug and care must be used to ensure that it is used in the appropriate instances.

Drug Interactions:

Tamsulosin or Flomax has the ability to alter the effectiveness of blood pressure medication.
