Zynac Injection 1ml
Description
Zynac injection is used to relieve short-term pain, especially after surgery or injury. It helps reduce inflammation, swelling, and discomfort. It contains aceclofenac as an active ingredient. It works by blocking the action of certain chemicals in the body that cause pain and swelling.
It should not be used if you have allergies to it or its ingredients, a history of stomach ulcers, severe kidney problems, or during pregnancy or breastfeeding. It is also not suitable if you have had allergic reactions to similar pain relievers.
Some people may experience side effects like nausea, dizziness, stomach pain, or diarrhoea. More serious effects can include liver or kidney issues, especially in older adults or people with existing health problems.
The medicine can interact with other drugs like lithium, blood thinners, diabetes medicines, and other painkillers. Always tell your doctor about all medicines you're taking before using them.
Inform your doctor if you have liver, kidney, or stomach problems, or if you experience symptoms such as black stools or a skin rash. Also, avoid driving if you feel dizzy and limit alcohol intake while on this medicine.
