Black, tarry, or bloody stools. Severe heartburn or indigestion. Precautions Use coated tablets, which may lessen stomach irritation. Avoid drinking alcoholic beverages while taking medicines. Take medicines with a full glass of water or milk or with food, which may reduce irritation.
Some medicines cause nerve and muscle activity to slow down in the stomach.
This slowing down causes the contents of the stomach to empty at a slower rate than normal. Drugs that may cause this delay include anticholinergics and drugs used to treat Parkinson's disease and depression. Warning signs Nausea. Feeling of fullness. Vomiting of food eaten many hours earlier.
