Certainly didn't mean to suggest they are, especially not without professional medical advice. (Not just to check the dose or have a different one prescribed, but for a PPI to protect stomach lining from taking a lot of ibuprofen for example.) The non-prescription doses on the packaging are suitable short-term, for a one-off headache or to manage a fever, but continued use (a bad injury meaning your taking it several days even) should be with advice, that might differ.
