Ciprofloxacin

Taking ciprofloxacin increases the risk that you will develop tendinitis (swelling of a fibrous tissue that connects a bone to a muscle) or have a tendon rupture (tearing of a fibrous tissue that connects a bone to a muscle) during your treatment or for up to several months afterward. These problems may affect tendons in your shoulder, your hand, the back of your ankle, or in other parts of your body. Tendinitis or tendon rupture may happen to people of any age, but the risk is highest in people over 60 years of age. Tell your doctor if you have or have ever had a kidney, heart, or lung transplant; kidney disease; a joint or tendon disorder such as rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function); or if you participate in regular physical activity. Tell your doctor and pharmacist if you are taking oral or injectable steroids such as dexamethasone, methylprednisolone (Medrol), or prednisone (Rayos). If you experience any of the following symptoms of tendinitis, stop taking ciprofloxacin, rest, and call your doctor immediately: pain, swelling, tenderness, stiffness, or difficulty in moving a muscle. If you experience any of the following symptoms of tendon rupture, stop taking ciprofloxacin and get emergency medical treatment: hearing or feeling a snap or pop in a tendon area, bruising after an injury to a tendon area, or inability to move or to bear weight on an affected area.

Taking ciprofloxacin may cause changes in sensation and nerve damage that may not go away even after you stop taking ciprofloxacin. This damage may occur soon after you begin taking ciprofloxacin. Tell your doctor if you have ever had peripheral neuropathy (a type of nerve damage that causes tingling, numbness, and pain in the hands and feet). If you experience any of the following symptoms, stop taking ciprofloxacin and call your doctor immediately: numbness, tingling, pain, burning, or weakness in the arms or legs; or a change in your ability to feel light touch, vibrations, pain, heat, or cold.

Taking ciprofloxacin may affect your brain or nervous system and cause serious side effects. This can occur after the first dose of ciprofloxacin. Tell your doctor if you have or have ever had seizures, epilepsy, cerebral arteriosclerosis (narrowing of blood vessels in or near the brain that can lead to stroke or ministroke), stroke, changed brain structure, or kidney disease. If you experience any of the following symptoms, stop taking ciprofloxacin and call your doctor immediately: seizures; tremors; dizziness; lightheadedness; headaches that won't go away (with or without blurred vision); difficulty falling asleep or staying asleep; nightmares; not trusting others or feeling that others want to hurt you; hallucinations (seeing things or hearing voices that do not exist); thoughts or actions towards hurting or killing yourself; feeling restless, anxious, nervous, depressed, memory changes, or confused, or other changes in your mood or behavior.

Taking ciprofloxacin may worsen muscle weakness in people with myasthenia gravis (a disorder of the nervous system that causes muscle weakness) and cause severe difficulty breathing or death. Tell your doctor if you have myasthenia gravis. Your doctor may tell you not to take ciprofloxacin. If you have myasthenia gravis and your doctor tells you that you should take ciprofloxacin, call your doctor immediately if you experience muscle weakness or difficulty breathing during your treatment.

Talk to your doctor about the risks of taking ciprofloxacin.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ciprofloxacin. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs) or the manufacturer's website to obtain the Medication Guide.

Ciprofloxacin is used to treat or prevent certain infections caused by bacteria such as pneumonia; gonorrhea (a sexually transmitted disease); typhoid fever (a serious infection that is common in developing countries); infectious diarrhea (infections that cause severe diarrhea); and infections of the skin, bone, joint, abdomen (stomach area), and prostate (male reproductive gland), Ciprofloxacin is also used to treat or prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack) and inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack). Ciprofloxacin may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and sinus infections, or certain types of urinary tract infections if there are other treatment options. Ciprofloxacin extended-release (long-acting) tablets are used to treat kidney and urinary tract infections; however, some types of urinary tract infections should only be treated with ciprofloxacin extended release tablets if no other treatment options are available. Ciprofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.

Antibiotics such as ciprofloxacin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Ciprofloxacin comes as a tablet, a suspension (liquid), and an extended-release tablet to take by mouth with or without food. The tablets and suspension are usually taken twice a day, and the extended-release tablets are usually taken once a day. When used to treat gonorrhea, the tablets and suspension may be given as a single dose. Take ciprofloxacin at around the same time(s) every day. The length of your treatment depends on the type of infection you have. Your doctor will tell you how long to take ciprofloxacin. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ciprofloxacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

One type of ciprofloxacin cannot be substituted for another. Be sure that you receive only the type of ciprofloxacin that was prescribed by your doctor. Ask your pharmacist if you have any questions about the type of ciprofloxacin you were given.

Do not take ciprofloxacin with dairy products or calcium-fortified juices alone. However, you may take ciprofloxacin with a meal that includes these foods or drinks.

Swallow the tablets whole; do not crush, or chew them. If you doctor tells you to to split the 250-mg or 500-mg tablet, it may be broken in half along the scored line. Swallow the extended-release tablets whole; do not split, crush, or chew them. If you cannot swallow tablets or extended-release tablets whole, tell your doctor.

If you are taking the suspension, shake the bottle very well for 15 seconds before each use to mix the medication evenly. Swallow the correct dose without chewing the granules in the suspension. Close the bottle completely after each use. Do not give the suspension to a patient through a feeding tube.

You should begin feeling better during the first few days of your treatment with ciprofloxacin. If your symptoms do not improve or if they get worse, call your doctor. If you are being treated for a urinary tract infection, call your doctor if you develop fever or back pain during or after your treatment. These symptoms may be signs that your infection is worsening.

Take ciprofloxacin until you finish the prescription, even if you feel better. Do not stop taking ciprofloxacin without talking to your doctor unless you experience certain serious side effects listed in the IMPORTANT WARNING and SIDE EFFECTS sections If you stop taking ciprofloxacin too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

In the event of biological warfare, ciprofloxacin may be used to treat and prevent dangerous illnesses that are deliberately spread such as tularemia and anthrax of the skin or mouth. Ciprofloxacin is also sometimes used to treat cat scratch disease (an infection that may develop after a person is bitten or scratched by a cat), Legionnaires' disease (type of lung infection), chancroid (genital sores caused by bacteria), granuloma inguinale (donovanosis; a sexually transmitted disease), and infections of the outer ear that spread to the bones of the face. Ciprofloxacin may also be used to help treat tuberculosis and Crohn's disease (condition in which the immune system attacks the lining of the digestive tract causing pain, diarrhea, weight loss, and fever). Ciprofloxacin is also sometimes used to prevent traveler's diarrhea in certain patients and to prevent infections in patients who have fever and are at high risk for infection because they have very few white blood cells, people who are having certain types of surgery, and those people in close contact with someone who is sick with meningitis. Talk to your doctor about the risks of using this medication for your condition.

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

Ciprofloxacin may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (https://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store the tablets and extended-release tablets at room temperature and away from excess heat and moisture (not in the bathroom). Store the suspension in the refrigerator or at room temperature, closed tightly, for up to 14 days. Do not freeze ciprofloxacin suspension. Discard any suspension that is left over after 14 days.

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 and the laboratory. Your doctor may order certain lab tests to check your body's response to ciprofloxacin. If you have diabetes, your doctor may ask you to check your blood sugar more often while taking ciprofloxacin.

Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish taking ciprofloxacin, call 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.
