Pivmecillinam

Pivmecillinam is used for the treatment of certain types of urinary tract infections (UTIs; infection of the bladder or kidney) in adult female patients. Pivmecillinam is in a class of medications called penicillins. It works by killing bacteria.

Pivmecillinam comes as a tablet to take by mouth. It is usually taken with or without food three times a day for 3 to 7 days. Take pivmecillinam at around the same times 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 pivmecillinam exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

You should begin to feel better during the first few days of treatment with pivmecillinam. If your symptoms do not improve or get worse, call your doctor.

Take pivmecillinam until you finish the prescription, even if you feel better. If you stop taking pivmecillinam too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

• tell your doctor if you have carnitine deficiency from an inherited disorder (something you were born with) such as methylmalonic aciduria or propionic acidemia or porphyria (disorder resulting from build up of certain chemicals related to red blood cell proteins).

Keep this medication in the blister pack 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. https://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 (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Keep all appointments with your doctor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

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.
