Aspirin and aspirin-caffeine in postpartum pain relief.
In two double-blind randomized, balanced, single oral dose studies with 140 women, a combination of 800 mg aspirin and 64 mg caffeine (aspirin-caffeine) was compared to 650 mg aspirin and to placebo. In patients with moderate to severe uterine or episiotomy pain, there was greater analgesic response with active drugs when the initial pain intensity was more severe. In patients with severe episiotomy pain, aspirin-caffeine was more effective than 650 mg aspirin (p less than 0.05) at the second and third hours. There was no difference between analgesic effects of aspirin and aspirin-caffeine in women with severe uterine pain.
