What is succimer?
Succimer is used to treat lead poisoning.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I take succimer?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
If you cannot swallow a capsule whole, open it and sprinkle the medicine into a spoonful of soft food. Swallow the mixture right away without chewing. Do not save it for later use.
You may also empty the medicine beads into a spoon, swallow all of the beads, and then drink a glass of juice or fruit-flavored drink.
Drink plenty of liquids to keep your kidneys working properly so they can help eliminate the lead from your body.
Succimer is usually given daily for 19 days in a row. You may need to receive more than one course of treatment. Use succimer regularly to get the most benefit.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the lead is completely cleared from your body.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using succimer.
Call your doctor if your symptoms do not improve, or if they get worse while using succimer.
