What is Lampit?
Lampit (nifurtimox) is an antiprotozoal medicine. Antiprotozoal medicines kill or prevent the growth of organisms known as protozoans.
Lampit is a prescription medicine used to treat Chagas disease, a condition caused by the parasite Trypanosoma cruzi. Chagas disease occurs most commonly in Mexico, Central America, and South America.
Lampit is for use in children from birth through their 17th year. A child must weigh at least 5.5 pounds (2.5 kilograms) before taking this medicine.
It is not known if Lampit is safe and effective in children weighing less than 5.5 pounds (2.5 kg).
Do not drink alcohol while taking Lampit. Alcohol may increase the frquency and severity of side effects experienced when taking nifurtimox.
Before taking this medicine
Your child should not use Lampit if he or she is allergic to nifurtimox.
Tell your child's doctor if the child has ever had:
a brain injury;
mental illness or psychosis;
kidney disease (or if the child is on dialysis);
liver disease; or
porphyria (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system).
Nifurtimox can harm an unborn baby if the mother or the father is using this medicine. Sexually active females and males should use effective birth control.
If you are female, you may need to have a negative pregnancy test before starting this treatment. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 6 months after your last dose.
If you are male, use effective birth control if your sex partner is able to get pregnant. Keep using birth control for at least 3 months after your last dose.
Tell your doctor right away if a pregnancy occurs while either the mother or the father is using Lampit.
If you are breastfeeding, tell your doctor if you notice symptoms in the nursing baby such as fussiness, decreased appetite, vomiting, rash, or fever.
How should I use Lampit?
Take Lampit exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your child's dose.
The usual dosage of Lampit is 3 times per day with food, taken for 60 days. Follow your doctor's dosing instructions very carefully.
Each tablet should be swallowed whole or split in half. You may split a tablet by breaking it along scored line with your fingertip. Do not split a Lampit tablet using a tablet-cutting device.
If the child cannot swallow a tablet whole, place the tablet into 1/2 teaspoon of water. Allow the tablet to completely dissolve (in about 30 seconds). Give the mixture right away with food.
