Amino acids injection is used for nutritional support of newborn babies (including babies with low birth weight) and children requiring total parenteral nutrition (TPN). It may also be used to treat negative nitrogen balance in the blood. This medicine may be also used together with dextrose to provide a more complete profile of amino acids for protein synthesis.
This medicine is to be given only by or under the direct supervision of your doctor.
Before Using
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:
