When the medicine is taken shortly after ingestion of food, there may be an increase in the amount of drug which is absorbed, a decrease in maximum concentration and a lengthening in the time to maximum concentration. Maximum levels occur about one hour after ingestion if drug is taken on an empty stomach or two hours after dosing when taken with food.

Elimination. In some patients, trazodone may accumulate in the plasma.
