Check whether ibuprofen is suitable first
NHS lists circumstances in which ibuprofen may be unsuitable and interactions with medicines such as anticoagulants, steroids and some blood-pressure treatments. Follow the exact package directions and ask a pharmacist when uncertain. Adding vitamin C does not cancel those risks. [1]
More vitamin C does not protect the stomach
NIH describes nausea, diarrhea and abdominal cramps with high vitamin C intake. The inspected evidence does not establish vitamin C as protection against ibuprofen-related ulcers or bleeding. Do not increase either product because the other is being taken. [2][1]
Avoid duplicate pain medicines
NHS advises against taking ibuprofen with other NSAIDs such as naproxen or aspirin without appropriate advice. A combined cold remedy can complicate the regimen. Check its pain-relief ingredients as well as the vitamin content. [1]
Respond to serious symptoms rather than changing supplement timing
Imagine stomach pain appears during regular ibuprofen use. Review the medicine promptly; signs of stomach bleeding require urgent care. The useful response is assessment of the symptom and regimen, not an unsupported rule to move vitamin C a few hours later. [1]
