Flomax capsules are indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia such as poor urine flow and frequent visits to the bathroom.

 

Flomax Dosage and treatment

Flomax capsule 0.4 mg once daily is recommended as the dose for the treatment of the signs and symptoms of BPH. It should be administered once daily following a meal. For those patients who fail to respond to the Flomax 0.4 mg dose after two to four weeks of dosing, the dose of Flomax capsules can be increased to 0.8 mg once daily. If Flomax capsules administration is discontinued or interrupted for several days at either the 0.4 mg or 0.8 mg dose, therapy should be started again with the 0.4 mg once daily dose.

Expert Opin Drug Saf. 2014. Cardiovascular and ocular safety of α1-adrenoceptor antagonists in the treatment of male lower urinary tract symptoms. α1-Adrenoceptor antagonists (α-blockers) represent first-line drug treatment for male lower urinary tract symptoms. Their adverse events (AEs) include asthenia, dizziness, nasal congestion, arterial (orthostatic) hypotension and intraoperative floppy iris syndrome (IFIS). This report focuses on cardiovascular and ocular AEs of α-blockers as related to their mechanism of action and subtype selectivity. The incidence of hypotension differs between α-blockers. It is greatest with doxazosin or terazosin, but others including tamsulosin can also lead to hypotension especially upon treatment initiation. Concomitant antihypertensive medication increases the incidence of hypotension with some α-blockers. Use of α(1A)-selective blockers, evening dosing and drug intake after a meal can reduce the risk of hypotension. IFIS can occur with all drugs exerting α(1)-adrenoceptor antagonist properties and has especially been reported for tamsulosin. It makes cataract surgery more challenging but does not constitute a health risk to patients. IFIS seems to result from inhibition of iris dilator muscle contraction and occurs in men or women, even after α-blockers have been discontinued. To reduce the risk of IFIS, the authors suggest taking a careful drug history, postponing α-blocker treatment for patients with scheduled cataract surgery and careful counseling of patients taking α-blockers.

Questions
Q. Is saw palmetto as effective as Flomax for BPH symptoms?
   A. Flomax is much more powerful than saw palmetto. However, it is possible to alternate every other day the use of Flomax with prostate herbs such as saw palmetto or a combination such as Prostate Power Rx. This way the side effects from Flomax would be less and the effectiveness should still be good.

 

Q. I'd like to know, what are the real differences between Avodart and Flomax? I'm currently taking Flomax and I believe that both medicines reduce semen. Is there something that I can take, while continuing to use either medication, that would be able to improve this situation without diminishing to effects of either medication?
   A. Avodart is a medication that blocks the 5alpha-reductase inhibitor enzymes thus blocking the formation of the hormone DHT. Flomax, tamsulosin hydrochloride, is an antagonist of alpha1A adrenoceptors in the prostate and does not effect testosterone or DHT levels. See sperm for suggestions on how to improve semen and sperm quality and quantity.

 

I have just been diagnosed with BPH, had several test and and a cystoscopy because of several urinary tract infections, was put on antibiotics for the infection and Flomax 4Mg for the prostate enlargement about 2 weeks later I was put on 8 Mg of Flomax because I still have some burning weak urine flow. Is there something natural I can use and get off perscription drugs. You can't talk to your doctor about natural products, they look at you like you crazy. Please Help and advise what I can use in place of Flomax. I do have confidence in you and your advise. I have used your products over the years and found them to exceptional. Your advise will be very much appreciated. I am a 70 year old male and I am taking blood pressure medication which is under control with Exforge and a hydrachloridedyasize.
    Perhaps the page on prostate health will help you.

 

Can I take an herbal natural prostate health formula with the 8 mg of Flomax which I would like to discontinue.
    This is a decision you are your doctor would need to make. It is possible the the use of a natural prostate pill can lower the required dosage of the medication, but it is not possible to make accurate predictions.
