Indocin (indomethacin) and Indocin IV (indomethacin) for Injection is a nonsteroidal anti-inflammatory drug (NSAID) used to treat severe rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, acute gouty arthritis, bursitis, and tendinitis. The brand name Indocin is no longer available in the U.S. but may be available as a generic termed indomethacin. Common side effects of Indocin (indomethacin) and Indocin IV (indomethacin) for Injection include:
- upset stomach,
- a feeling of bowel fullness,
- rectal irritation,
- skin rash,
- itching, or
- blurred vision.
Indocin is available in capsules in strengths of 25 and 50 mg, in suspension strength of 25 mg per 5 ml and as a suppository in strength of 50 mg per suppository. Initial doses usually start at 25 mg three times daily. Indocin IV (indomethacin) for Injection Sterile Vial contains 1 mg Indocin and is used by specialists in infants to close a patent ductus arteriosus in the heart and is not commonly prescribed. Indocin (indomethacin) ordinarily should not be prescribed for pediatric patients under 15 years old. In late pregnancy, Indocin (indomethacin and other NSAIDs) should be avoided because it may cause premature closure of the ductus arteriosus. Serious side effects of Indocin may include heart attack, stroke, skin changes (paleness, blisters, rash, and hives), weight gain, swelling, shortness of breath, tachycardia, unusual bleeding (including GI bleeding), jaundice, stomach pain, and pain with urination, bloody urine, blurry vision, and back pain. Patients with asthma that are aspirin-sensitive should avoid use of this drug. Indocin may reduce the effectiveness of ACE inhibitors and increase lithium (Eskalith, Lithobid) levels; use with aspirin or similar agents is not recommended. Caution is advised as Indocin may react with a number of other drugs so the prescribing physician will need a list of current medications. Indocin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus and infant; it is not recommended for use in breastfeeding women.
Our Indocin and Indocin, IV (indomethacin) for Injection Sterile Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving INDOCIN Capsules than in the group taking INDOCIN Suppositories or placebo.
In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with INDOCIN Suppositories or Capsules was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group.
The adverse reactions for INDOCIN Capsules listed in the following table have been arranged into two groups: (1) incidence greater than 1%; and (2) incidence less than 1%. The incidence for group (1) was obtained from 33 double-blind controlled clinical trials reported in the literature (1,092 patients). The incidence for group (2) was based on reports in clinical trials, in the literature, and on voluntary reports since marketing. The probability of a causal relationship exists between INDOCIN and these adverse reactions, some of which have been reported only rarely.
The adverse reactions reported with INDOCIN Capsules may also occur with use of the suspension.

Causal relationship unknown: Other reactions have been reported but occurred under circumstances where a causal relationship could not be established. However, in these rarely reported events, the possibility cannot be excluded. Therefore, these observations are being listed to serve as alerting information to physicians:
Hematologic: Although there have been several reports of leukemia, the supporting information is weak
Genitourinary: Urinary frequency
A rare occurrence of fulminant necrotizing fasciitis, particularly in association with Group Aβ hemolytic streptococcus, has been described in persons treated with nonsteroidal anti-inflammatory agents, including indomethacin, sometimes with fatal outcome
