Why is this medicine prescribed?
Lefamulin is used to treat community acquired pneumonia (a lung infection that developed in a person who was not in the hospital) caused by certain types of bacteria. Lefamulin is in a class of medications called pleuromutilin antibiotics. It works by slowing the growth or killing bacteria that cause infections.
Antibiotics such as lefamulin will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Lefamulin comes as a tablet to take by mouth. It is usually taken every 12 hours on an empty stomach (at least 1 hour before or 2 hours after a meal) for 5 days or for the remaining days of treatment after receiving this medication intravenously (into a vein). Take lefamulin at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lefamulin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole with a glass (6 to 8 oz) of water; do not split, chew, or crush them.
You should begin to feel better during the first few days of treatment with lefamulin. If your symptoms do not improve or get worse, call your doctor.
Take lefamulin until you finish the prescription, even if you feel better. If you stop taking lefamulin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
What special precautions should I follow?

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Keep all appointments with your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
