What is succimer?
Succimer is a chelating (KEE-late-ing) agent that is used to remove a heavy metal (such as lead) from the body. Succimer binds to lead in the blood and allows it to be passed out in the urine.
Succimer is used to treat lead poisoning.
Succimer may also be used for purposes not listed in this medication guide.

How should I take succimer?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
To make swallowing easier, you may open the succimer capsule and sprinkle the medicine into a spoonful of soft food. Swallow right away without chewing. Do not save the mixture for later use.
You may also open the capsule and 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. Get your prescription refilled before you run out of medicine completely.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the lead is completely cleared from your body.
While using succimer, you may need frequent blood tests. Your blood work will help your doctor determine how long to treat you with succimer. Your kidney function may also need to be checked.
Call your doctor if your symptoms do not improve, or if they get worse while using succimer.
Succimer can lower blood cells that help your body fight infections. This can make it easier for you to get sick from being around others who are ill. Your blood cells may need to be tested often.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
