• Ketoprofen capsules cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids.
• Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including ketoprofen capsules. Such patients should be closely monitored, and a reduction of dosage should be anticipated to avoid high blood levels of ketoprofen and/or its metabolites.
• Anemia is sometimes seen in patients receiving NSAIDs, including ketoprofen capsules. Patients receiving ketoprofen capsules who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored.
• Patients with asthma may have aspirin-sensitive asthma. ketoprofen capsules should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma.
• Advise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their health care provider immediately.
• Ketoprofen capsules, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death.
• Advise patients to stop taking ketoprofen capsules immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible.
• Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur.
• Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy.
• Patients should be informed of the signs of an anaphylactoid reaction (e.g., difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help
• Ketoprofen has been linked to a low rate of serum enzyme elevations during therapy and to rare instances of clinically apparent acute liver injury.

• lethargy
• drowsiness

• hypotension
• hypertension
• acute renal failure

Management of overdosage:

• Patients should be managed by symptomatic and supportive care following an NSAID overdose.
• There are no specific antidotes.

• This should be accomplished via emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) with a saline cathartic or sorbitol added to the first dose.
• Forced diuresis, alkalinization of the urine, hemodialysis or hemoperfusion would probably not be useful due to ketoprofen's high protein binding.

Can this medicine be used in pregnancy?
