Before taking Methionine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

This medicine has been tested in children and, in effective doses, has not been shown to cause different side effects or problems than it does in adults.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of racemethionine in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.

Interactions with Medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

How to use Methionine

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.
