I have received inquiries whether Ibuprofen is banned and if so the details.
FDA has been cagey.It is banned , but it is not said in so many words.
‘
Ibuprofen is produced industrially as a racemate. The compound, like other 2-arylpropionate derivatives (including ketoprofen, flurbiprofen, naproxen, etc.), does contain a stereocenter in the α-position of the propionate moiety. So two enantiomers of ibuprofen occur, with the potential for different biological effects and metabolism for each enantiomer. Indeed, the (S)-(+)-ibuprofen (dexibuprofen) was found to be the active form both in vitro and in vivo.
It was logical, then, to consider the potential for improving the selectivity and potency of ibuprofen formulations by marketing ibuprofen as a single-enantiomer product (as occurs with naproxen, another NSAID). Further in vivo testing, however, revealed the existence of an isomerase (alpha-methylacyl-CoA racemase), which converted (R)-ibuprofen to the active (S)-enantiomer.[40][41][42]‘ ( Wiki)
Obuprofen action and composition is identical.
These cause skin, allergy, Blisters,Male Dysfunction,Kidney Failure.
‘SIDE EFFECTS AND SPECIAL PRECAUTIONS
The most frequent side effects occurring with Ibuprofen are gastro-intestinal disturbances; reactions range from abdominal discomfort, nausea and vomiting, and abdominal pain to serious gastro-intestinal bleeding or activation of peptic ulcer.
CNS-related side effects include headache, dizziness, nervousness, tinnitus, depression, drowsiness, and insomnia. Hypersensitivity reactions may occur less frequently and include fever and rashes. Hepatotoxicity and aseptic meningitis which occur less frequently may also be hypersensitivity reactions. Ibuprofen can provoke bronchospasm in patients with asthma. Ibuprofen may cause cystitis and haematuria. They may also cause acute renal failure, interstitial nephritis, and nephrotic syndrome.
Other side effects include anaemias, thrombocytopenia, neutropenia, eosinophilia, agranulocytosis, abnormalities in liver function tests, blurred vision, changes in visual colour perception, and toxic amblyopia.
Precautions: Brufen should be given with care to the elderly, to patients with asthma or bronchospasm, bleeding disorders, cardiovascular disease, a history of peptic ulceration, and in liver or renal failure. Patients with congestive heart failure, cirrhosis, diuretic-induced volume depletion, or renal insufficiency require local synthesis of vasodilating prostaglandins to maintain renal perfusion, and therefore these patients are at greater risk of developing renal dysfunction due to NSAID-induced inhibition of renal prostaglandin synthesis.
Care is required in those who are also receiving coumarin anticoagulants. Patients who are sensitive to aspirin or other NSAIDs should generally not be given Ibuprofen.
Ibuprofen should be discontinued in patients who experience blurred or diminished vision, or changes in colour vision. Patients with collagen disease may be at increased risk of developing aseptic meningitis.’

In a confused sort of way it is banned .
The Drug Companies are very powerful and they will not easily let go.
