About phenoxybenzamine
दवा का प्रकार | An alpha-adrenoceptor blocker (also called an alpha-blocker) |
के लिए उपयोग किया जाता है | High blood pressure caused by phaeochromocytoma |
के रूप में उपलब्ध | Capsules |
Phaeochromocytoma is a tumour of your adrenal glands. With phaeochromocytoma, large quantities of chemicals are released from your adrenal glands, which narrow (constrict) your blood vessels. This causes episodes where your blood pressure increases significantly.
The treatment of choice for phaeochromocytoma is removal of the tumour by surgery. Phenoxybenzamine is sometimes prescribed as a short-term option in preparation for the surgery. It works by blocking sites on your blood vessels, known as alpha receptors. This blocking action reduces your उच्च रक्तचाप.

अक्सर पूछे जाने वाले प्रश्न
What is the main reason phenoxybenzamine is prescribed?
Phenoxybenzamine is primarily prescribed as a short-term treatment for high blood pressure that is caused by a phaeochromocytoma. This is a tumour that releases large amounts of chemicals, causing blood vessels to narrow and blood pressure to rise significantly. It's used to manage your blood pressure before surgery to remove the tumour.
How does phenoxybenzamine help with high blood pressure?
Phaeochromocytoma causes chemicals to be released which constrict your blood vessels, leading to high blood pressure. Phenoxybenzamine works by blocking specific sites, called alpha receptors, on your blood vessels. This blocking action helps to reduce your high blood pressure.
Can I take phenoxybenzamine if I have other health conditions?
Before starting phenoxybenzamine, it's important to inform your doctor about any existing health conditions. This includes kidney problems, heart disease, if you've had a heart attack or stroke, or if you have a rare inherited blood disorder called porphyria. Your doctor needs this information to ensure the medicine is suitable for you.
Is it important to take phenoxybenzamine at a specific time in relation to meals?
You can take phenoxybenzamine either before or after a meal. The most important thing is to try and take your doses at the same time each day to help you remember to take them regularly.
What should I do if I feel dizzy or faint after taking phenoxybenzamine?
Feeling dizzy or faint, especially when getting up, is a common side-effect. Try getting up more slowly from a lying or sitting position. If you start to feel dizzy, lie down to prevent fainting, and then sit for a few moments before standing. You should avoid driving or operating machinery if you are affected by dizziness.
What should I do if I miss a dose of phenoxybenzamine?
If you forget to take a dose, take it as soon as you remember. However, if you don't remember until the next day, you should skip the missed dose from the previous day and take your next dose as normal. Do not take two doses at the same time to compensate for a forgotten dose.
Can I take other medicines, including over-the-counter ones, with phenoxybenzamine?
It is crucial to inform your doctor about all medicines you are taking, including those available without a prescription, as well as herbal and complementary medicines. If you buy any new medicines while on phenoxybenzamine, always check with a pharmacist if they are suitable to take alongside it.
