The side effects of cytarabine sodium are mainly gastrointestinal adverse reactions, so taking it after meals can reduce the stimulation of the gastric mucosa, reduce the side effects on the stomach, and at the same time, it can slow down the speed of gastric emptying, which is conducive to the body’s absorption of the drug. Cytarabine Sodium belongs to the drugs that nourish cerebral nerves, and has a wide range of benefits for conditions related to neurological dysfunction symptoms.
