Give this medication exactly as directed by your veterinarian. Simplicef should be given with food to increase absorption in the body. Keep plenty of water available for your pet to drink. Do not give Simplicef at the same time as giving antacids such as Maalox or other stomach acid reducers such as Tagamet as this may decrease the absorption of Simplicef. Give all of the Simplicef even if your pet appears to be better. Symptoms may improve before the infection is completely treated. Store tablets at room temperature away from moisture or heat.
