INTRODUCTION

XIDORIN contains Midodrine which belongs to the group of medicines called Alpha -1 Selective Adrenergic Receptor Agonist. It is used to treat low blood pressure (hypotension) in adults. Symptoms of low blood pressure include blurred or fading vision, dizziness or light-headedness, fainting, feeling sick, difficult in concentrating.

Midodrine acts on the blood vessels via the sympathetic nervous system (part of nervous system that cause increase in heart rate, blood pressure, breathing rate, and dilatation of pupil) to correct imbalances of blood distribution, such as preventing too much blood pooling in the legs when standing up which may cause low blood pressure. Your doctor may regularly monitor the blood pressure when you are lying down and when you are standing up as there may be a risk of your blood pressure rising when you lie down (Ex. at night).

XIDORIN is not recommended for use in patients having severe heart disease. XIDORIN should be used with caution in patient having severe kidney disease, liver problems. Consult your doctor for advice before taking XIDORIN, if you are pregnant or breast-feeding. XIDORIN is not recommended for use in children and adolescents below the age of 18 years. The most common side effects of taking XIDORIN are increased blood pressure when lying down, headache, nausea (feeling sick), vomiting, heartburn. Consult your doctor if the symptom worsens.
