Neurotoxin from Clostridium botulinum; prevents ACh release from presynaptic membrane, causing temporary calming of muscle contractions by blocking the transmission of nerve impulses. Botulinum Toxin Type A blocks the signals between the nerve & its muscle. When this happens a lot of the limb tightness disappears which in tum, allows the muscle a better chance to grow normally. Just as important, Botulinum Toxin Type A therapy can put off surgery a little longer. By encouraging normal movement, child's body is given the chance to grow.

There are no known drug interactions and none well documented.

As with other immunoglobulin preparations, it should not be used in individuals with a prior history of severe reaction to other human immunoglobulin preparations. Individuals with selective immunoglobulin A deficiency have the potential for developing antibodies to immunoglobulin A and could have anaphylactic reactions to the subsequent administration of blood products that contain immunoglobulin A.

Serious adverse reactions were not observed in clinical trials. The most common adverse reaction was skin rash. Other reactions such as chills, muscle cramps, back pain, fever, nausea, vomiting, and wheezing were the most frequent adverse reactions observed during the clinical trials of similarly-prepared human IGIV products.

Pregnancy Category C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Patient Monitoring for Administration Patients should be well hydrated prior to the initiation. Assess renal function, including the measurement of blood urea nitrogen (BUN) or serum creatinine prior to the initial infusion. Periodic monitoring of renal function tests and urine output is particularly important in patients judged to have a potential risk for developing acute renal failure. Increases in serum creatinine and BUN have been observed as soon as one to two days following treatment with other IGIV products. During administration, monitor the patient's vital signs continuously and observe the patient carefully for any associated symptoms.
