ibuprofen
GENERIC
NAME: ibuprofen
BRAND NAME: Advil,
Children's Advil/Motrin, Medipren, Motrin, Nuprin,
Pediacare Fever etc.
DRUG CLASS AND MECHANISM:
Ibuprofen belongs to a class of drugs called
non-steroidal anti-inflammatory drugs (NSAIDs). Other
members of this class include naproxen (Aleve),
indomethacin (Indocin), nabumetone (Relafen) and several
others. These drugs are used for the management of mild
to moderate pain, fever, and inflammation.
Prostaglandins are chemicals that are made by the body
and are responsible for causing pain, fever and
inflammation. Ibuprofen blocks the enzyme that makes
prostaglandins (cyclooxygenase), resulting in lower
levels of prostaglandins. As a consequence,
inflammation, pain and fever are reduced. The FDA
approved ibuprofen in 1974.
PRESCRIPTION: Yes and
no
GENERIC AVAILABLE:
Yes
PREPARATIONS: Tablets of 200, 400,
600, and 800 mg; Chewable tablets of 50 and 100 mg;
Capsules of 200 mg; Suspension of 100 mg/2.5 ml and 100
mg/5 ml; Oral drops of 40
mg/ml.
STORAGE: Ibuprofen should be
stored at room temperature, between 15-30°C (59-86°F).
PRESCRIBED FOR: Ibuprofen is used
for the treatment of mild to moderate pain, inflammation
and fever.
DOSING: For minor aches, mild to
moderate pain, menstrual cramps and fever the usual
adult dose is 200 or 400 mg every 4 to 6 hours.
Arthritis is treated with 300 to 800 mg 3 or 4 times
daily. When under the care of a physician, the maximum
dose of ibuprofen is 3.2 g daily. Otherwise, the maximum
dose is 1.2 g daily. Individuals should not use
ibuprofen for more than 10 days for the treatment of
pain or more than 3 days for the treatment of a fever
unless directed by a physician.
Children 6 months to 12 years of age
usually are given 5-10 mg/kg of ibuprofen every 6-8
hours for the treatment of fever and pain. The maximum
dose is 40 mg/kg daily. Juvenile arthritis is treated
with 20 to 40 mg/kg/day in 3-4 divided doses.
Ibuprofen should be taken with
meals.
DRUG INTERACTIONS: Ibuprofen is
associated with several suspected or probable
interactions that can affect the action of other drugs.
Ibuprofen may increase the blood levels of
lithium (Eskalith) by
reducing the excretion of lithium by the kidneys.
Increased levels of lithium may lead to lithium
toxicity. Ibuprofen may reduce the blood
pressure-lowering effects of drugs that are given to
reduce blood pressure. This may occur because
prostaglandins play a role in the regulation of blood
pressure. When ibuprofen is used in combination with
aminoglycosides (e.g., gentamicin) the blood levels of
the aminoglycoside may increase, presumably because the
elimination of aminoglycosides from the body is reduced.
This may lead to aminoglycoside-related side effects.
Individuals taking oral blood thinners or anticoagulants
(e.g., warfarin) should avoid ibuprofen because
ibuprofen also thins the blood, and excessive blood
thinning may lead to bleeding.
PREGNANCY: There are no adequate
studies of ibuprofen in pregnant women. Therefore,
ibuprofen is not recommended during
pregnancy.
NURSING MOTHERS: Most NSAIDs are
excreted in breast milk. In general, mothers who breast
feed should avoid the use of NSAIDs because of possible
effects on the fetus.
SIDE EFFECTS: The most common side
effects from ibuprofen are rash, ringing in the ears,
headaches, dizziness, drowsiness, abdominal pain,
nausea, diarrhea, constipation and heartburn. Ibuprofen
may cause ulceration of the stomach or intestine, and
the ulcers may bleed. Sometimes, ulceration and bleeding
can occur without abdominal pain, and black tarry
stools, weakness, and dizziness upon standing
(orthostatic hypotension) may be the only signs of a
problem. NSAIDs reduce the flow of blood to the kidneys
and impair function of the kidneys. The impairment is
most likely to occur in patients with preexisting
impairment of kidney function or congestive heart
failure, and use of NSAIDs in these patients should be
done cautiously. People who are allergic to other
NSAIDs, including aspirin, should not use ibuprofen.
Individuals with asthma are more likely to experience
allergic reactions to ibuprofen and other
NSAIDs.
