Generic Name: Succinylcholine (suk-sin-il-KOE-leen)
Brand Name: Anectine and Quelicin

Quelicin has been associated with rapid muscle breakdown resulting in life-threatening heart rhythms, cardiac arrest, and death in children. Male children younger than 8 years of age seem to be at a higher risk, but cases have also been reported in adolescents. Because it is hard to determine which children may be at risk, Quelicin should only be used in an emergency situation.

Quelicin is used for:

Relaxing muscles during surgery or when using a breathing machine (ventilator). It is also used to induce anesthesia or when a tube must be inserted in the windpipe. It may also be used for other conditions as determined by your doctor.

Quelicin is a depolarizing muscle relaxant. It works by keeping muscles from contracting, which causes paralysis of the muscles in the face and those used to breathe and move.

Do NOT use Quelicin if:

• you are allergic to any ingredient in Quelicin
• you have recently had a severe burn, trauma, nerve damage, or upper body movement injury
• you have or have a family history of muscle disease or malignant hyperthermia (a life-threatening state that includes high body temperatures)

Contact your doctor or health care provider right away if any of these apply to you.
