Astwin 1mg Injection belongs to the class of drugs called vasopressin receptor agonists used for the treatment of bleeding oesophageal varices and the emergency treatment of type 1 hepatorenal syndrome (rapidly progressive kidney failure) in patients with ascites (abdominal swelling due to accumulation of fluid) and liver cirrhosis (scarring of the liver). Bleeding oesophageal varices occur when there is bleeding from dilated veins in the food pipe leading to your stomach.

Astwin 1mg Injection contains Terlipressin, a synthetic pituitary hormone that breaks down in the body to release a substance called lysine vasopressin that is used to stop bleeding from leaking varicose veins in the food pipe. It works by narrowing the affected blood vessels and restricting the blood flow through them. Thus, it helps to control bleeding.

Astwin 1mg Injection will be administered by a healthcare professional; do not self-administer. Sometimes, Astwin 1mg Injection may cause common side effects such as headache, diarrhoea, abdominal cramps, high or low blood pressure, too slow heart rate, pale skin, and insufficient blood circulation in arms, legs and skin. Most of these side effects of Astwin 1mg Injection do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

If you are allergic to Terlipressin or other medicines, please tell your doctor.

Bleeding oesophageal varices: These occur when varices (swollen veins) in the lower oesophagus (food pipe) rupture and bleed. When liver blood flow is obstructed, blood builds up in other blood vessels nearby, including those in the lower oesophagus. This causes blood vessels to dilate and swell as a result of the increased blood flow. The swollen veins are known as oesophageal varices which may leak blood and rupture eventually. Often, it does not cause any symptoms until they rupture and bleed. If the bleeding is mild, the symptoms include black, tarry stools, and if the bleeding is severe, the symptoms include stomach pain, blood in your vomit, rectal bleeding, lightheadedness, and bloody stools.
