How does it work?

Tamsulosin, the active ingredient in Flomax, belongs to a class of medicines called alpha-1A blockers.

Tamsulosin relaxes the muscles in the prostate. This helps dilate the urethra and make urination easier.

How is it used?

One 0.4 mg hard capsule is taken approximately 30 minutes after the first meal daily, ideally at the same time each day. Take the capsule standing or sitting with enough liquid. The hard capsules should not be chewed.

The effects of the medicine are usually felt within the first 48 hours. If the 0.4 mg dose does not provide relief, it can be increased to 0.8 mg once a day. Never increase the dose without consulting your doctor.

Why to buy Flomax?

Tamsulosin (trade name Flomax) is a drug used to treat enlarged prostate and chronic prostatitis. It was approved by the FDA in 1997. In 2009, the manufacturer Boehringer Ingelheim lost its patent for the drug molecule. As a result, numerous inexpensive generic drugs are now available.

Tamsulosin belongs to a class of drugs known as alpha-blockers, which relax both the bladder neck muscles and the muscle of the prostate itself.

The drug Flomax (tamsulosin) is used to treat a number of common conditions in men, including:

  • benign prostatic hyperplasia (BPH), a common age-related enlargement of the prostate
  • chronic prostatitis not associated with bacterial infection
  • passage of kidney stones
  • urinary retention

Flomax (tamsulosin) is not approved for use in women or children.

Tamsulosin is only available as 0.4 mg hard capsules.

The effect occurs in 2 to 6 weeks of regular use. Call your doctor if your urination doesn't improve within two weeks or if you experience serious, persistent, or worsening side effects, such as a rash, priapism, or fainting.

What are the side effects of the drug Flomax?

Although tamsulosin (Flomax) is considered a safe drug for long-term use, there are a number of side effects that should be considered. Common side effects include headache, breast pain, abnormal ejaculation, rhinitis, weakness, drowsiness, cough, rash, nausea, blurred vision, decreased libido, and priapism.

Other undesirable effects include dizziness, orthostatic dysregulation and fainting. These are the symptoms of orthostasis, which usually appear within the first eight weeks of treatment. Because of the possible effects on blood pressure, patients with low blood pressure, heart problems, or heart failure should be closely monitored while taking Flomax.

How is the effect of Flomax pills affected by alcohol consumption?

Caution should be exercised when taking Flomax pills with alcohol beverages. Drinks containing alcohol can increase the effects of Flomax and lower blood pressure. When blood pressure is too low, patients may experience dizziness and weakness.

The drug Flomax does not typically affect blood pressure, and manufacturers do not provide formal advice on alcohol consumption. However, ethanol has been clinically proven to potentiate the antihypertensive effects of alpha-blockers, including selective ones like Flomax. Some experts advise the patient to limit alcohol consumption while using this drug.

How does Flomax interact with other medicines?

Before starting treatment with Flomax (tamsulosin), you should tell your doctor about all prescription drugs and herbal products you are taking.

Simultaneously taking tamsulosin with sexual enhancers can lead to a severe drop in blood pressure.

The effect of Flomax is not affected by simultaneous administration with the painkillers paracetamol, ibuprofen, co-codamol and aspirin. This means that you can safely combine the drug Flomax with these pain relievers.

CYP3A4 and CYP2D6 are two enzymes in the liver that break down tamsulosin. The drugs like cimetidine, ketoconazole, erythromycin, terbinafine and paroxetine inhibit CYP3A4 and CYP2D6, which increases the plasma level of tamsulosin. This can increase the risk of low blood pressure and fainting.

Taking Flomax (tamsulosin) concomitantly with antihypertensive drugs may increase the risk of orthostatic hypotension.

Contact the doctor if you combine any of the following drugs with Flomax pills and feel dizzy: baclofen; alprostadil; medicines used to treat high blood pressure such as ramipril, bisoprolol and candesartan; anesthetics; nitrates such as glyceryl trinitrate; benzodiazepines such as diazepam; other alpha blockers such as prazosin; levodopa; tizanidine.

Voriconazole, verapamil, ritonavir, aprepitant, ketoconazole, boceprevir, erythromycin, clarithromycin, itraconazole, paroxetine, telithromycin and cobicistat - all of these drugs can increase plasma concentrations of tamsulosin. This increases the risk of side effects after taking tamsulosin.

Boceprevir, ombitasvir, paritaprevir, ritonavir and dasabuvir can lead to serious consequences when used in combination with tamsulosin.

A very good drug that eliminates the signs of a cold or flu. Flomax helped me. After three days of taking this drug, my condition has really disappeared. The only thing I didn't like is a bitter taste. All in all, I can only recommend Flomax.


Flomax is an excellent non-steroidal anti-inflammatory drug with an optimal price-performance ratio. It has a rapid onset of action and the minimal effect on the gastrointestinal tract when taken after a meal.
