This medicine is used for the treatment of benign prostatic hyperplasia or BPH (enlarged prostate). Tamsulosin often improves male urinary symptoms due to BPH in as little as one week. It has been shown to maintain long-term symptom relief. Flomax is also indicated to treat urinary tract and kidney stones (to help with the passage of kidney stones), chronic prostatitis, for urinary retention and overactive bladder. It works by relaxing muscles in the prostate and bladder neck. This improves urine flow and reduces BPH symptoms. Tamsulosin HCl may be used alone or in combinations with other urological drugs, such as finasteride, dutasteride, tolterodine or solifenacin.

  • Retention of urine - R33


    Indications and usage:

    Flomax (Tamsulosin Hydrochloride) is an alpha1 adrenoceptor antagonist indicated for treatment of the signs and symptoms of benign prostatic hyperplasia.

    Flomax capsules are not indicated for the treatment of hypertension.


    Dosage and administration:

  • Tamsulosin 0.4 mg once daily taken approximately one-half hour following the same meal each day. Flomax capsules should not be crushed, chewed or opened.
  • Can be increased to 0.8 mg once daily for patients who fail to respond to the 0.4 mg dose after 2 to 4 weeks of dosing.
  • If discontinued or interrupted for several days, therapy should start again with the 0.4 mg once-daily dose.


    Dosage forms and strengths:

    Flomax (Tamsulosin Hydrochloride) capsules 0.2 mg and 0.4 mg.


    Overdosage:

    Should overdosage of Tamsulosin capsules lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, then administration of intravenous fluids should be considered. If necessary, vasopressors should then be used and renal function should be monitored and supported as needed. Laboratory data indicate that tamsulosin hydrochloride is 94% to 99% protein bound; therefore, dialysis is unlikely to be of benefit.


    Contraindications:

    Contraindicated in patients known to be hypersensitive to tamsulosin hydrochloride or any component of Flomax capsules.


    Warnings and precautions:

  • Advise patients about the possibility of symptoms related to postural hypotension and to avoid situations where injury could result should syncope occur.
  • Should not be used in combination with strong inhibitors of CYP3A4. Use with caution in combination with moderate inhibitors of CYP3A4, with strong or moderate inhibitors of CYP2D6, in patients known to be CYP2D6 poor metabolizers, or in combination with other cytochrome P450 inhibitors.
  • Should not be used in combination with other alpha adrenergic blocking agents.
  • Exercise caution with concomitant administration of warfarin.
  • Advise patients about the possibility and seriousness of priapism.
  • Intraoperative Floppy Iris Syndrome has been observed during cataract and glaucoma surgery in some patients. Advise patients considering cataract or glaucoma surgery to tell their ophthalmologist that they have taken Flomax capsules.
  • Advise patients to be screened for the presence of prostate cancer prior to treatment and at regular intervals afterwards.


    Adverse reactions, side effects:

    The most common adverse events ( >= 2% of patients and at a higher incidence than placebo) with the 0.4 mg dose or 0.8 mg dose were headache, dizziness, rhinitis, infection, abnormal ejaculation, asthenia, back pain, diarrhea, pharyngitis, chest pain, cough increased, somnolence, nausea, sinusitis, insomnia, libido decreased, tooth disorder, and blurred vision.

    To report suspected adverse reactions, contact Boehringer Ingelheim company or U.S. FDA.


    Drug interactions:

  • Flomax (Tamsulosin Hydrochloride) capsules 0.4 mg should not be used with strong inhibitors of CYP3A4 (e.g., ketoconazole). This medication should be used with caution in combination with moderate inhibitors of CYP3A4 (e.g., erythromycin), in combination with strong (e.g., paroxetine) or moderate (e.g., terbinafine) inhibitors of CYP2D6, or in patients known to be CYP2D6 poor metabolizers, particularly at a dose higher than 0.4 mg (e.g., 0.8 mg).
  • Concomitant use of PDE5 inhibitors with tamsulosin can potentially cause symptomatic hypotension.


    Use in specific populations:

  • Pediatric use: tamsulosin is not indicated for use in pediatric populations.
  • Geriatric use: no overall differences in efficacy or safety vs younger patients, but greater sensitivity of some older adults cannot be ruled out.
  • Renal impairment: has not been studied in patients with end-stage renal disease.
  • Hepatic impairment: has not been studied in patients with severe hepatic impairment.


    Patient counseling information:

  • Hypotension: advise the patient about the possible occurrence of symptoms related to postural hypotension, such as dizziness, when taking Flomax capsules, and they should be cautioned about driving, operating machinery, or performing hazardous tasks.
  • Drug interactions: advise the patient that Tamsulosin HCl should not be used in combination with strong inhibitors of CYP3A4.
  • Priapism: advise the patient about the possibility of priapism as a result of treatment with Tamsulosin Hydrochloride (Flomax) capsules and other similar medications. Patients should be informed that this reaction is extremely rare, but if not brought to immediate medical attention, can lead to permanent erectile dysfunction (impotence).
  • Screening for prostate cancer: prostate cancer and BPH frequently co-exist; therefore, screen patients for the presence of prostate cancer prior to treatment with Flomax capsules and at regular intervals afterwards.
  • Intraoperative floppy iris syndrome: advise the patient when considering cataract or glaucoma surgery to tell their ophthalmologist that they have taken Tamsulosin capsules.
  • Administration: advise the patient that Flomax (Tamsulosin Hydrochloride) capsules should not be crushed, chewed or opened.
