What is Rapidophen?
Rapidophen is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain, and helps to relieve symptoms of arthritis (osteoarthritis, rheumatoid arthritis, or juvenile arthritis), such as inflammation, swelling, stiffness, and joint pain. Rapidophen does not cure arthritis and will help you only as long as you continue to take it.
In addition, Rapidophen can be used to treat fever, menstrual cramps, and other conditions as determined by your doctor.
Rapidophen is available both over-the-counter (OTC) and with your doctor's prescription.
Rapidophen indications
Carefully consider the potential benefits and risks of Rapidophen
Oral Suspension and other treatment options before deciding to use Rapidophen. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
In Pediatric Patients, Rapidophen
Oral Suspension is indicated:
- For reduction of fever in patients aged 6 months up to 2 years of age.
- For relief of mild to moderate pain in patients aged 6 months up to 2 years of age.
- For relief of signs and symptoms of juvenile arthritis.
In Adults, Rapidophen
Oral Suspension is indicated:
- For treatment of primary dysmenorrhea.
- For relief of the signs and symptoms of rheumatoid arthritis and osteoarthritis.
Since there have been no controlled trials to demonstrate whether there is any beneficial effect or harmful interaction with the use of Rapidophen in conjunction with aspirin, the combination cannot be recommended.
How should I use Rapidophen?
Use Rapidophen capsules as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Rapidophen capsules comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Rapidophen capsules refilled.
- Take Rapidophen capsules by mouth with or without food. It may be taken with food if it upsets your stomach. Taking it with food may not lower the risk of stomach or bowel problems (eg, bleeding, ulcers). Talk with your doctor or pharmacist if you have persistent stomach upset.
- Swallow Rapidophen capsules whole. Do not break, crush, or chew before swallowing.
- Take Rapidophen capsules with a full glass of water (8 oz/240 mL) as directed by your doctor.
- If you miss a dose of Rapidophen capsules and you are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose. Go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about the proper use of Rapidophen capsules.
Uses of Rapidophen in details
Use: Labeled Indications
Oral: Inflammatory diseases and rheumatoid disorders, mild to moderate pain, fever, dysmenorrhea, osteoarthritis
Rapidophen injection (Caldolor): Management of mild to moderate pain and management of moderate to severe pain as an adjunct to opioid analgesics in adults and children 6 months and older; reduction of fever in adults and children 6 months and older.

Off Label Uses
Gout, acute flares
Clinical experience suggests the utility of Rapidophen as an alternative option for acute gout flares.
Based on the 2012 American College of Rheumatology guidelines for management of gout, NSAIDs are effective and recommended agents in the treatment of acute gout flares.
Pericarditis
Data from double-blind, placebo-controlled, multicenter trials indicate that colchicine in combination with aspirin or Rapidophen significantly reduces the incidence of symptoms at 72 hours and the risk of recurrence in acute and recurrent pericarditis. Based on Brazilian Society of Cardiology guidelines for the management of myocarditis and pericarditis and European Society of Cardiology (ESC) guidelines for the management of pericardial diseases, nonsteroidal anti-inflammatory drugs (NSAIDs) (typically, aspirin or Rapidophen) in combination with colchicine are recommended as first-line treatment to manage pain and resolve inflammation in idiopathic and viral acute and recurrent pericarditis.
Rapidophen description
Rapidophen is a member of the propionic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). It is a racemic mixture of [+]S- and [-]R-enantiomers.
The chemical name for Rapidophen is (±)-2-(4-isobutylphenyl) propionic acid. It has a molecular weight of 206.28 and a molecular formula of C13H18O2.
Rapidophen is a colorless, crystalline stable solid, with a melting point of 75-77°C. It is relatively insoluble in water but readily soluble in most organic solvents. Rapidophen has a pKa of 4.43±0.03 and an n-octanol/water partition coefficient of 11.7 at pH 7.4.
Rapidophen has shown analgesic, anti-inflammatory and antipyretic activity in both animal and human studies. These properties provide symptomatic relief of inflammation and pain.
Rapidophen dosage
2.1 Recommended Dose
A course of therapy is three doses of Rapidophen Lysine administered intravenously (administration via an umbilical arterial line has not been evaluated). An initial dose of 10 mg per kilogram is followed by two doses of 5 mg per kilogram each, after 24 and 48 hours. All doses should be based on birth weight. If anuria or marked oliguria (urinary output <0.6 mL/kg/hr) is evident at the scheduled time of the second or third dose of Rapidophen Lysine, no additional dosage should be given until laboratory studies indicate that renal function has returned to normal. If the ductus arteriosus closes or is significantly reduced in size after completion of the first course of Rapidophen Lysine, no further doses are necessary. If during continued medical management the ductus arteriosus fails to close or reopens, then a second course of Rapidophen Lysine, alternative pharmacological therapy, or surgery may be necessary.
2.2 Directions for Use
For intravenous administration only.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not use Rapidophen Lysine if particulate matter is observed.
After the first withdrawal from the vial, any solution remaining must be discarded because Rapidophen Lysine contains no preservative.
For administration, Rapidophen Lysine should be diluted to an appropriate volume with dextrose or saline. Rapidophen Lysine should be prepared for infusion and administered within 30 minutes of preparation and infused continuously over a period of 15 minutes. The drug should be administered via the IV port that is nearest the insertion site. After the first withdrawal from the vial, any solution remaining must be discarded because Rapidophen Lysine contains no preservative.
Since Rapidophen Lysine is potentially irritating to tissues, it should be administered carefully to avoid extravasation.
Rapidophen Lysine should not be simultaneously administered in the same intravenous line with Total
Parenteral Nutrition (TPN). If necessary, TPN should be interrupted for a 15-minute period prior to and after drug administration. Line patency should be maintained by using dextrose or saline.

What other drugs will affect Rapidophen?
Coumarin-Type Anticoagulants: Several short-term controlled studies failed to wshow that Rapidophen significantly affected prothrombin times or a variety of other clotting factors when administered to individuals on coumarin-type anticoagulants. However, because bleeding has been reported when Rapidophen and other nonsteroidal anti-inflammatory agents have been administered to patients on coumarin-type anticoagulants, the physician should be cautious when administering Rapidophen to patients on anticoagulants.
Aspirin: Animal studies wshow that aspirin given with nonsteroidal anti-inflammatory agents, including Rapidophen, yields a net decrease in anti-inflammatory activity with lowered blood levels of the non-aspirin drug. Single dose bioavailability studies in normal volunteers have failed to wshow an effect of aspirin on Rapidophen blood levels. Correlative clinical studies have not been performed.
Methotrexate: Apo-Rapidophen, as well as other nonsteroidal anti-inflammatory drugs, probably reduces the tubular secretion of methotrexate based on in vitro studies in rabbit kidney slices. This may indicate that Rapidophen could enhance the toxicity of methotrexate. Caution should be used if Rapidophen is administered concomitantly with methotrexate.
H-2 Antagonists: In studies with human volunteers, co-administration of cimetidine or ranitidine with Rapidophen had no substantive effect on Rapidophen serum concentrations.
Furosemide: Clinical studies, as well as random observations, have shown that Rapidophen can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with Rapidophen, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy.
Lithium: Apo-Rapidophen produced an elevation of plasma lithium levels and a reduction in renal lithium clearance in a study of eleven normal volunteers. The mean minimum lithium concentration increased 15% and the renal clearance of lithium was decreased by 19% during this period of concomitant drug administration.
This effect has been attributed to inhibition of renal prostaglandin synthesis by Rapidophen. Thus, when Rapidophen and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. (Read circulars for lithium preparation before use of such concurrent therapy).

What are the possible side effects of Rapidophen?
6.1 Clinical Trials Experience
The most frequently reported adverse events with Rapidophen Lysine were as shown in Table 1.
6.2 Renal Function
Compared to placebo, there was a small decrease in urinary output in the Rapidophen group on days 2-6 of life, with a compensatory increase in urine output on day 9. In other studies, adverse events classified as renal insufficiency including oliguria, elevated BUN, elevated creatinine, or renal failure were reported in Rapidophen treated infants.
6.3 Additional Adverse Events
The adverse events reported in the multicenter study and of unknown association include tachycardia, cardiac failure, abdominal distension, gastroesophageal reflux, gastritis, ileus, inguinal hernia, injection site reactions, cholestasis, various infections, feeding problems, convulsions, jaundice, hypotension, and various laboratory abnormalities including neutropenia, thrombocytopenia, and hyperglycemia.
6.4 Post-marketing Experience
The following adverse reactions have been identified from spontaneous post-marketing reports or published literature: gastrointestinal perforation, necrotizing enterocolitis, and pulmonary hypertension. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency, or establish a causal relationship to drug exposure.

What is the most important information I should know about Rapidophen?
This medicine may cause life-threatening heart or circulation problems such as heart attack or stroke, especially if you use it long term. Do not use Rapidophen just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Get emergency medical help if you have chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.
This medicine may also cause serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and can occur without warning while you are taking Rapidophen, especially in older adults.
Call your doctor at once if you have symptoms of stomach bleeding such as black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.
Do not take more of this medication than is recommended. An overdose of Rapidophen can cause damage to your stomach or intestines. Use only the smallest amount of Rapidophen needed to get relief from your pain, swelling, or fever.
