Glycine — Uses, Dosage, Side Effects & Safety

Drug class: Amino Acid (Irrigating Solution/Adjunctive Therapy)

Overview

Glycine is an amino acid that is used medically as a sterile, non-electrolyte irrigating solution during surgical procedures, especially in urology (such as transurethral resection of the prostate or bladder). It helps to clear the surgical field and prevent tissue dehydration. Glycine also plays a role as a dietary supplement and is sometimes used as an adjunct in the management of certain metabolic disorders. In the body, glycine is involved in protein synthesis and acts as a neurotransmitter in the central nervous system. Key points for patients: Glycine irrigation is not absorbed in significant amounts when used as directed during surgery, but if absorbed systemically, it may cause side effects. Always use under medical supervision. Oral glycine supplements should only be taken as advised by a healthcare provider.
