What is indomethacin?

Indomethacin is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Indomethacin works by reducing hormones that cause inflammation and pain in the body.

Indomethacin is used to treat pain or inflammation caused by many conditions such as arthritis, gout, ankylosing spondylitis, bursitis, or tendinitis.

Indomethacin may also be used for purposes not listed in this medication guide.

What is the most important information I should know about indomethacin?

This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use indomethacin. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking indomethacin. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Do not drink alcohol while taking indomethacin. Alcohol can increase the risk of stomach bleeding caused by indomethacin. Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar toindomethacin (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen.

How should I take indomethacin?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Take indomethacin with food or milk to lessen stomach upset. Do not crush, chew, break, or open an extended-release capsule. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time. Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

If you take indomethacin for a long period of time, your doctor may want to check you on a regular basis to make sure this medication is not causing harmful effects. Do not miss any scheduled visits to your doctor.

This medication can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are using indomethacin.

Store indomethacin at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze.

What happens if I miss a dose?

If you are taking indomethacin on a regular schedule, take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose.

If you are taking indomethacin as needed, take the missed dose if it is needed, then wait the recommended or prescribed amount of time before taking another dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of an indomethacin overdose may include nausea, vomiting, stomach pain, drowsiness, black or bloody stools, coughing up blood, shallow breathing, fainting, or coma.

What should I avoid while taking indomethacin?

Do not drink alcohol while taking indomethacin. Alcohol can increase the risk of stomach bleeding caused by indomethacin. Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to indomethacin (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen. Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Indomethacin can make your skin more sensitive to sunlight and sunburn may result. Use a sunscreen (minimum SPF 15) and wear protective clothing if you must be out in the sun.

What is the shelf life of the pills?

• The expiry date is mentioned on each blister. It is different for different batches. The shelf life is 2 years from the date of manufacture and would differ from batch to batch depending on when they were manufactured.

Other Useful Information:

Calcium: A mineral found mainly in the hard part of bones, where it is stored. Calcium is added to bones by cells called osteoblasts and is removed from bones by cells called osteoclasts. Calcium is essential for healthy bones. It is also important for muscle contraction, heart action, nervous system maintenance, and normal blood clotting. Food sources of calcium include dairy foods, some leafy green vegetables such as broccoli and collards, canned salmon, clams, oysters, calcium-fortified foods, and tofu. According to the National Academy of Sciences, adequate intake of calcium is 1,200 milligrams a day (four glasses of milk) for men and women 51 and older, 1,000 milligrams a day for adults 19 through 50, and 1,300 milligrams a day for children 9 through 18. The upper limit for calcium intake is 2.5 grams daily.

Cavities: Holes in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Small cavities may not cause pain, and may be unnoticed by the patient. Larger cavities can collect food, and the inner pulp of the affected tooth can become irritated by bacterial toxins, foods that are cold, hot, sour, or sweet - causing toothache.

Naturopathy: A system of therapy based on preventative care, and on the use of heat, water, light, air, and massage as primary therapies for disease. Some naturopaths use no medications, either pharmaceutical or herbal. Some recommend herbal remedies only. A few who are licensed to prescribe may recommend pharmaceuticals in those cases where they feel their use is warranted.

Naturopathy is an American healthcare profession. It was founded in the US as a formal healthcare system at the turn of the 20th century by medical practitioners from various natural therapeutic disciplines. By the early 1900s, more than 20 naturopathic medical schools existed, and naturopathic physicians were licensed in most States. Today there are more than 1,000 licensed naturopathic doctors in the US.

As practiced today, naturopathic medicine integrates traditional natural therapeutics -- including botanical medicine, clinical nutrition, homeopathy, acupuncture, traditional oriental medicine, hydrotherapy, and naturopathic manipulative therapy -- with modern scientific medical diagnostic science and standards of care. The medical research base of naturopathic practice consists of empirical documentation of treatments using case history observations, medical records, and summaries of practitioners' clinical experiences.

At present, the two accredited naturopathic medical schools in the US have active research departments. Naturopathic researchers have investigated the pharmacology and physiological effects of nutritional and natural therapeutic agents, and naturopathic physicians have been active in the investigation of new homeopathic remedies and in the natural treatment of women's health problems. The most recently completed naturopathic study in women's health tested the clinical and endocrine effects of a botanical formula as an alternative to estrogen replacement therapy.

Blood: The familiar red fluid in the body that contains white and red blood cells, platelets, proteins, and other elements. The blood is transported throughout the body by the circulatory system. Blood functions in two directions: arterial and venous. Arterial blood is the means by which oxygen and nutrients are transported to tissues while venous blood is the means by which carbon dioxide and metabolic by-products are transported to the lungs and kidneys, respectively, for removal from the body.

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".

Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres."

Disease: Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.

Doctor: In a medical context, any medical professional with an MD, a PhD, or any other doctoral degree. The term doctor is quite nonspecific. A doctor may, for example, be a physician, psychologist, biomedical scientist, dentist, or veterinarian. In a nonmedical context, a professor of history might be addressed as doctor, an eminent theologian might be named a doctor of a church, and a person awarded an honorary doctorate by a college or university might also be called a doctor.

The word "doctor" comes from the Latin "docere" meaning to teach. A doctor was a teacher, especially a learned or authoritative one.
