The increased loading dose can be repeated as many times as required, titrated against the patient's pain level and the side effects of the opioid.Patient weight is a useful guide in initiating PCA dosing, even though the correlation between analgesic requirement and weight is poor.

Patient-controlled analgesia (PCA) is a method of providing analgesia using a computerized pump that allows patients to self-administer predetermined doses of opioids.
The delivery of small, frequent intravenous boluses of opioids results in reasonably constant serum concentrations of the opioid.
Since there is marked inter-patient variability in the amount of analgesic required for pain relief, the loading dose must be titrated to effect.
Many studies have demonstrated a five fold variability in the quantity of intravenous opioid required to produce equivalent analgesia after surgery.
