Flomax (Tamsulosin)

• The dosage of Flomax is based on the individual's medical condition and response to treatment.
• Flomax capsules are usually taken once a day, approximately 30 minutes after the same meal each day.
• The capsules should be swallowed whole and should not be crushed, chewed, or opened.
• Take Flomax regularly to derive the most benefit from it. To help remember, it should be taken at the same time each day.
• If a dose is missed, it should be taken as soon as remembered. However, if it is almost time for the next dose, the missed dose should be skipped, and the regular dosing schedule should be continued. Extra medicine should not be taken to make up for a missed dose.
• If Flomax has not been taken for several days, contact your healthcare provider to determine if restarting at a lower dose is necessary.
• It may take up to 4 weeks before symptoms improve. If the condition does not improve or worsens, inform your healthcare provider.

Flomax should not be used if there is an allergy to tamsulosin or similar medicines such as alfuzosin, doxazosin, prazosin, silodosin, or terazosin.

Flomax should not be used in combination with strong inhibitors of CYP3A4, such as ketoconazole.

Patients should be informed about the possibility of priapism as a rare but serious side effect of treatment with Flomax and similar medications. Immediate medical attention is necessary to prevent permanent erectile dysfunction (impotence).

Prostate cancer and benign prostatic hyperplasia (BPH) frequently coexist. Patients should be screened for the presence of prostate cancer before treatment with Flomax capsules and at regular intervals afterward.

Patients considering cataract or glaucoma surgery should inform their ophthalmologist that they have taken Flomax capsules to prevent potential complications.

Flomax can cause orthostatic hypotension, leading to a drop in blood pressure when moving from a sitting to a standing position. This is more likely during initiation of Flomax or when increasing the dose.

Patients should inform their healthcare provider about all medical conditions, especially liver disease, kidney disease, or prostate cancer, as Flomax may not be suitable for individuals with these conditions.

Always consult your healthcare provider for personalized advice and guidance regarding the use of Flomax.
