Summary
Brief summary

This study will review the intervention of administration of oral propranolol tablets to patients with HHT (Hereditary Haemorrhagic Telangiectasia) . Patients will be monitored to see if Propranolol helps reduce epistaxis (nosebleeds) . The most common symptom of HHT is having recurrent, spontaneous nosebleeds. Propranolol has been used for a similar purpose in another group of patients with good effect. If it should work it would be a very simple and cost effective way to reduce patient symptoms and approve quality of life for these patients..
