Flomax for Prostatitis – Side Effects and Warnings

Flomax (FLO-maks)

Flomax (tamsulosin hydrochloride [tam-SOO-loe-sin HIGH-droe-KLOR-ide]) is an alpha-adrenergic blocker (also called an alpha blocker). This medication relaxes prostate and bladder muscles to enable easier urination.

Flomax Warnings

Flomax has been shown to cause dizziness and vertigo. In patients taking Flomax (tamsulosin) for prostatitis or other alpha blockers, there is a potential risk for fainting. When starting treatment with Flomax, patients should avoid situations where injury may occur as a result of fainting. There is risk of severe hypotension especially in the first few weeks of taking Flomax.

On very rare occasions, Flomax and other alpha blockers have been linked to penile erection pain that can last over four hours and is unrelated to sexual activity (priapism). Patients should seek immediate medical attention for this condition, as it may lead to permanent impotence if not treated properly.

Sexual side effects may include erectile dysfunction, loss of libido, reduced sperm count, reduce semen volume, and movement of sperm, ejaculation problems, and abnormal orgasm.

Do not use this medication to treat high blood pressure.

Talk to you doctor if you are having cataract surgery, as Flomax is associated with serious complications.

Why Is Flomax Prescribed for Prostatitis?

Flomax and other alpha blockers may decrease the risk of acute urinary retention and improve lower urinary tract symptoms, including pain. Flomax may help control prostatitis, but it will not cure it.

In cases of acute bacterial prostatitis, Flomax or other alpha blockers may be used to improve disruptive, irritating symptoms of urination.

In cases of chronic bacterial prostatitis, this medication or other alpha blockers may reduce the risk of recurrence.

In cases of chronic pelvic pain syndrome (CPPS), Flomax or other alpha blockers may improve urinary symptoms and symptoms of pain and discomfort.
