A common side effect of ibuprofen is irritation of the gastric mucosa and ibuprofen should be avoided in patients with existing gastric pathology, such as ulcers, gastritis, or upper GI bleeding. Ibuprofen is not recommended as an analgesic in this patient due to his actively bleeding ulcer. Consultation with the treating physician to explore alternative pain control strategies is appropriate. Saying that you will administer the ibuprofen immediately is not appropriate. Naproxen is also an NSAID. Recommended treatments for tension headaches do include relaxation, meditation and oral rehydration, however analgesic drugs are a first-line therapeutic option.
