Proper Use

Drug information provided by: Merative, Micromedex®

You should not take more of this medicine, or take it more often, than your doctor ordered. You should also make sure that you get enough protein in your diet. This is especially important in infants. Infants who get too much racemethionine and not enough protein may not gain weight as they should. If you have any questions about this, ask your health care professional.

Take racemethionine with, or just after, meals.

For patients taking racemethionine capsules:

  • If you are unable to swallow the capsule, the contents may be added to juice, water, or warm milk or infant formula.

For patients taking racemethionine oral solution:

  • Use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.

Make certain your health care professional knows if you are on any special diet, such as a low-protein diet.
