Tamsulosin capsules
What do tamsulosin capsules do?
TAMSULOSIN (Flomax(R)) is used to treat enlargement of the prostate gland in men (benign prostatic hyperplasia or BPH). It is not for use in women. Tamsulosin works by relaxing muscles in the prostate and bladder neck at the site of the obstruction. This improves urine flow and reduces BPH symptoms.
What should my health care professional know before I take tamsulosin?
They need to know if you have any of the following conditions:
• kidney disease
• liver disease
• low blood pressure
• prostate cancer
• an unusual or allergic reaction to tamsulosin, other medicines, foods, dyes, or preservatives
How should I take this medicine?
Always take tamsulosin capsules by mouth after a meal, about 30 minutes after the same meal every day. Follow the directions on the prescription label. Swallow the capsules whole with a drink of water; do not crush, chew, or open capsules. Do not take your medicine more often than directed. Do not stop taking except on your prescriber's advice.
Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.
What if I miss a dose?
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
