About PHENOXYBENZAMINE
PHENOXYBENZAMINE belongs to a group of medicines called antihypertensives used to treat hypertension (high blood pressure) caused by phaeochromocytoma (tumour of the adrenal glands). Hypertension is a condition in which the force of blood against the artery walls is very high. It will be an addition to the workload of the heart and arteries.
PHENOXYBENZAMINE contains Phenoxybenzamine, an alpha-blocker that opposes certain hormones produced by the tumour of the adrenal gland that constricts and narrows blood vessels. Thereby, it relaxes and widens blood vessels and lowers high blood pressure.
Take PHENOXYBENZAMINE as prescribed by your doctor. You are advised to take PHENOXYBENZAMINE for as long as your doctor has prescribed it for you based on your medical condition. In some cases, you may experience dizziness, lightheadedness, blocked nose, diarrhoea, tiredness, narrowing of the pupil of the eye or ejaculation failure during intercourse. Most of these side effects of PHENOXYBENZAMINE do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.
If you are allergic to PHENOXYBENZAMINE or any other medicines, please tell your doctor. PHENOXYBENZAMINE is not recommended for children unless advised by a doctor. If you are pregnant or breastfeeding, please consult a doctor. Avoid taking PHENOXYBENZAMINE if you ever had a heart attack or stroke. You are recommended to avoid alcohol consumption with PHENOXYBENZAMINE as it may increase the risk of dizziness or fainting. Drive only if you are alert as PHENOXYBENZAMINE may cause dizziness or light-headedness.

Patients Concern
Disease/Condition Glossary
Blood pressure is the measurement of the heart's force to pump blood to all parts of the body. Hypertension is a chronic condition in which blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg and, diastolic pressure is 90 mm of Hg. Normal blood pressure lies in between 90/60 mm of Hg and 120/80 mm of Hg. If the blood pressure is 140/90 mmHg or greater, it is considered high blood pressure.
