CompositionKCl Injection is used to treat and prevent low potassium levels in the blood (hypokalaemia). It is a single-ingredient medicine containing potassium chloride, and belongs to a group of medicines called electrolyte replacements.
This medicine is used when potassium is low because of illness, heavy vomiting or diarrhoea, certain medicines or other fluid losses, and tablets are not suitable. Potassium is essential for normal heart rhythm, muscles and nerves. It must always be diluted and given by a healthcare professional as a slow drip into a vein, never as an undiluted injection, and your blood potassium will be checked during treatment.
Once you are well enough to eat, potassium-rich foods such as bananas, oranges, potatoes, tomatoes and pulses can help maintain healthy levels, if your doctor agrees.
Before treatment, tell your doctor if you have kidney disease, heart disease, high potassium levels, or dehydration, and about all other medicines you take, especially certain blood pressure medicines and water tablets. Tell your doctor if you are pregnant or breastfeeding. Tell your healthcare team straight away if you notice pain or swelling at the drip site, muscle weakness, tingling, or a slow or irregular heartbeat. Do not stop the treatment unless your doctor advises you to do so.
