Ibuprofen belongs to a class of drugs called non-steroidal anti-inflammatory
drugs (NSAIDs). 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. Ibuprofen should be taken with meals.
Availability of Ibuprofen
Ibuprofen is available in 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.
What conditions is Ibuprofen used for?
Ibuprofen is used for the treatment of mild to moderate pain, inflammation and fever.
Although both ibuprofen and acetaminophen reduce menstrual pain, ibuprofen
appears to have more potent effects.
Ibuprofen Dosage
For minor aches, mild to moderate pain, menstrual cramps and fever the
usual adult dose is ibuprofen 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 2 grams 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 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.
Ibuprofen for children
The first head-to-head study of three common painkillers found that ibuprofen
works best, at least for kids with broken bones, bruises and sprains. Available
generically and under the brand names Advil and Motrin, ibuprofen beat generic
acetaminophen and codeine in an emergency room study of 300 children treated at
a Canadian hospital. The youngsters, aged 6 to 17, were randomly assigned to
receive standard doses of one of the three medicines. They then periodically
rated their pain. Half an hour later, ratings were similar in the three groups.
But starting an hour after taking the medicine, children who got ibuprofen
reported substantially greater pain relief than the other two groups.
Ibuprofen and
Pregnancy
There are no adequate studies of
ibuprofen in pregnant women.
Therefore, ibuprofen is not recommended during pregnancy.
Ibuprofen and Breastfeeding
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.
Ibuprofen Side Effects
The most common ibuprofen side effects are rash, ringing in the ears, headaches, dizziness, drowsiness, abdominal pain, nausea, diarrhea, constipation and heartburn. Serious Ibuprofen side effect is 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. Renal ibuprofen side effects include reduction of blood flow to the kidneys and impaired 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 ibuprofen 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.
Ibuprofen, Aspirin, and Stroke
There is a drug-drug interaction between ibuprofen and aspirin, with
ibuprofen affecting aspirin's ability to inhibit platelet clumping or
aggregation that can lead to fatal blood clots. Researchers compared the extent
and duration of platelet clumping with aspirin 325 mg alone, with ibuprofen
alone and with aspirin 325 mg given two hours after ibuprofen 400 mg in 12
healthy subjects. Duration of inhibition of platelet aggregation with aspirin
alone was 72 to 96 hours. This was significantly longer than the inhibition of
only 4 to 6 hours with aspirin followed by ibuprofen, and with ibuprofen alone.
Thus, it appears the presence of ibuprofen prevents the irreversible inhibition
of platelet clumping produced by aspirin needed for secondary prevention of
stroke.
Ibuprofen questions
Q. Is hearing loss an ibuprofen side effect?
A. A serious ibuprofen side effect when used daily for
prolonged periods is ringing in the ear which could lead to hearing loss.
Q. At times, not always, my testicles become very small
and my libido becomes shot. I have a varicocele on each testicle and doctors
have told me that varicoceles only effect fertility and not testosterone or
libido. But I disagree. varicoceles are not always that apparent but sometimes I
think when they do become very apparent is when my testicles shrink and my
testosterone production or sperm production hinders and my libido suffers. this
is just my theory but recently i started taking about 600 mg of ibuprofen for my
sore throat and hat did i notice, my varicoceles not only became very unapparent
but my testicles became fuller as well, returning my libido. Then when I went
about 4 days without ibuprofen the same problems came back. when i then took
another high dose of ibuprofen it helped
again. I was just wondering if you might know why this may be? maybe I'm way off
and it's just a coincidence but it seems like 600 mg of ibuprofen seems to help
me with my situation.
A. We have not heard of the effect of ibuprofen on libido before,
but unusual reactions can occur in some people.
