This product contains a potent xanthine (i.e., caffeine and caffeine-like stimulants) mixture, about 220 mg per regular 2-capsule serving. Therefore, Leptopril is not intended for use by pregnant or nursing women. Not for use by individuals under the age of 18 unless directed by a doctor. Consult your physician before use if you are sensitive to stimulants. If you or your health-care provider have any questions, please call our customer service department at: 1-800-564-9146. A recent report discussed a genetic abnormality that prevents the body from assimilating xanthines (including caffeine). If you suffer from this genetic abnormality, do not take any product containing xanthines. Keep out of reach of children. Use only as directed. Individual results will vary. Use in conjunction with any sensible diet and exercise program. For persons sensitive to the effects of xanthines (i.e., caffeine and caffeine-like stimulants) start by taking only 1 capsule as directed above and do not exceed a total of 2 capsules per day. Limit the use of caffeine-containing medications, foods, or beverages while taking this product because too much caffeine may cause nervousness, irritability, sleeplessness, and occasionally rapid beat. Do not exceed 4 capsules per day. Not to be used as a casual diet-aid. Before starting this or any weight-control program, check with your health-care provider to make sure you are in overall good health.
