Generally, after pushing the button on the PCA, initial relief of discomfort can begin in as little as five minutes. The PCA medication kicks in quickly, but usually lasts for only a few hours â a much shorter time period than oral pain pills. Oral pain pills dissolve in the stomach and take between 30-45 minutes to start working from the time they are swallowed. Because these pills dissolve slowly in the stomach, they generally work to control pain for 3-4 hours at a time.
