Faq for PHENOXYBENZAMINE - ORAL

Phenoxybenzamine is an oral medication that belongs to a class of drugs called alpha blockers. It is used to treat high blood pressure, certain urinary problems, and an adrenal gland tumor called pheochromocytoma.

Phenoxybenzamine works by relaxing and widening the blood vessels, allowing blood to flow more easily. This helps to lower blood pressure and improve urinary symptoms.

The most common side effects of phenoxybenzamine include dizziness, drowsiness, lightheadedness, nasal congestion, headache, nausea, and vomiting. These side effects are usually mild and go away on their own.

Phenoxybenzamine is usually taken orally with or without food. The dosage and frequency will be determined by your doctor based on your condition. It is important to follow your doctor's instructions and not exceed the prescribed dose.

Phenoxybenzamine is not recommended for use during pregnancy unless absolutely necessary. It may harm the unborn baby. It is also not known if the drug passes into breast milk, so it is advised to consult with your doctor before taking this medication while breastfeeding.

Phenoxybenzamine may interact with other medications, including certain antidepressants, antipsychotics, and blood pressure medications. It is important to inform your doctor about all the medications you are taking, including over-the-counter drugs and herbal supplements, to avoid any potential interactions.

Phenoxybenzamine may take several weeks to reach its full effect in treating high blood pressure. It is important to continue taking the medication as prescribed by your doctor, even if you do not notice immediate results.

No, you should not stop taking phenoxybenzamine suddenly without consulting your doctor. Abruptly discontinuing the medication may cause a sudden rise in blood pressure, leading to serious complications. Your doctor will advise you on the proper way to taper off the medication if necessary.

Phenoxybenzamine may cause drowsiness and dizziness, so it is important to avoid activities that require mental alertness, such as driving or operating machinery. It is also important to limit alcohol consumption as it can worsen these side effects.
