Flomax CR (tamsulosin) 0.4 mg, while effective for relieving benign prostatic hyperplasia (BPH) symptoms, can cause side effects. Common side effects include dizziness, lightheadedness, and a stuffy or runny nose. These usually subside as your body adjusts to the medication. However, report any persistent or worsening symptoms to your doctor.
Serious Side Effects
Less common, but more serious, are side effects such as fainting, rapid heartbeat, and allergic reactions (rash, itching, swelling). Seek immediate medical attention if you experience these. Furthermore, Flomax can lower blood pressure, so inform your doctor about all medications you take, especially those affecting blood pressure.
Precautions
Before starting Flomax CR, discuss any pre-existing conditions, such as liver or kidney problems, or a history of fainting. Avoid driving or operating machinery until you know how the medication affects you. Sudden, significant drops in blood pressure are possible, particularly when standing up quickly. Consider changing position slowly. Also, be aware that Flomax may interact with other medications. Consult your doctor or pharmacist for a complete medication review.
Intraoperative Floppy Iris Syndrome (IFIS)
If you are scheduled for cataract surgery or other eye procedures, inform your ophthalmologist that you are taking Flomax. This medication can increase the risk of IFIS, a condition that can complicate eye surgery.
