Your doctor has information on how to recognise and treat an overdose. Ask your doctor if you have any concerns.

While you are having Leucovorin Calcium Injection

Things you must do

If you become pregnant while taking this medicine, tell your doctor immediately.

If you are about to have any blood tests, tell your doctor that you have been given this medicine. It may interfere with the results of some tests.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may do some tests on your blood and urine to make sure the medicine is working.

Things you must not do

Do not have Leucovorin Calcium Injection to treat any other complaints unless your doctor tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how Leucovorin Calcium Injection affects you. This medicine may cause fainting or seizures in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
