Medical Care: " Dietary adjustment is the primary form of therapy. o Advise patients to reduce or restrict products containing lactose. o Prehydrolyzed milk (LACTAID) is available and is effective. o Yogurt and fermented products, such as cheeses, are better tolerated than regular milk. o Soya-based milk or food products are well tolerated. " Commercially available lactase enzyme preparations (LACTAID or Lactrase) are effective in reducing symptoms; however, they may not be effective in some patients, partially due to insufficient dosing. " Supplemental calcium should also be recommended. " In secondary lactase deficiency, treatment is directed at the underlying cause. Diet: " Avoid or reduce intake of lactose-containing foods. " Most patients who are lactose intolerant can ingest as much as 240 mL of milk without an exacerbation of their symptoms. " Certain medications and foods contain hidden lactose, such as breads, margarine, salad dressings, and candies. DRUG TREATMENT : 1. DIGESTIVE ENZYMES : - LACTASE ENZYMES
