Further information

Dibenyline 10mg Capsules belong to a group of medicines known as alpha blockers. These interfere with messages
sent through nerves to control blood pressure.
Dibenyline 10mg Capsules are used to treat high blood pressure caused by a tumour of the adrenal glands called
phaeochromocytoma. There are two adrenal glands, one on top of each kidney. In phaeochromocytoma, certain
substances are released from the adrenal glands into the bloodstream in large quantities, causing high blood pressure.
Your medicine is normally used when other alternative treatments are not appropriate.

DO NOT take Dibenyline 10mg Capsules if:
• You know that you are allergic to Phenoxybenzamine Hydrochloride or any of the other ingredients (listed in Section
6 at the end of this leaflet), or to any other medicine that is used to lower blood pressure.
• You have ever had a stroke.
• You have had a heart attack (coronary thrombosis) within the last month.
Speak to your doctor before you take this medicine if one of these applies to you.
Take special care with Dibenyline 10mg Capsules if:
• You are being treated for shock, or your blood pressure is abnormally low and unable to maintain an adequate supply
of blood around your body.
• You have angina (chest pains).
• You know that you have heart disease or heart failure (e.g. swelling of the ankles).
• You know that you have thickening of the arteries including those in the brain
• You have ever had kidney problems which damaged your kidneys.
Speak to your doctor before you take this medicine if one of these applies to you.

pressure such as:

calcium channel blockers (e.g. amlodipine, lacidipine).
