Zeltacin is a medicine that gives you extra calcium if you have low calcium in your blood and symptoms like numbness or muscle cramps.
Your doctor will decide the right dose for you or your child to bring calcium levels back to normal, usually starting with 10 ml for adults.
This medicine is given as a slow injection into a vein (intravenously) while you are lying down, with your heart carefully monitored.
Your doctor will decide the maximum amount you can have each day based on your calcium levels.
