Wesom 40mg Injection

Esomeprazole injection is a proton pump inhibitor (PPI) that lowers the amount of acid your stomach makes. It is used for a short time when treatment by mouth is not possible, for example to:

• treat acid reflux (GORD), where stomach acid comes up into the food pipe and causes pain and heartburn
• treat or prevent stomach ulcers caused by anti-inflammatory painkillers (NSAIDs)
• help stop bleeding from a stomach or duodenal ulcer coming back after an endoscopy

It can be used in adults and in children aged 1 to 18 for reflux.

This medicine is given by a doctor or nurse in hospital or a clinic.

• It is given as an injection or a drip (infusion) into a vein.
• Your doctor decides how much you need and for how long. It is only used for a short time, while you cannot take medicine by mouth.
• Tell the nurse if you notice pain or swelling where the needle goes in.
• If you think you have been given too much, tell your doctor straight away.
