5mg a day was too much and he was having bad side effects, extreme lethargy, he stopped eating,and drinking and his diarrhea actually got worse. Half a pill ever other day was not enough his stool was normal the first day then back to diarrhea the second. Half a pill mg a day seems to be the formula that works for him. He tolerates it well,and his stool remains normal. Mischief is much more active and healthy now,and is actually gaining weight. I am very pleased. Like I said I think it saved his life. Also the drug is very inexpensive $10 bucks a month
Several brands of IVIG have been approved by the Food and Drug Adminsitration (FDA) (see table in Appendix). There is a lack of reliable evidence that any one brand of IVIG is more effective than other brands. However, immune globulin products may differ from each other in ways that may be important in a particular patient. Different manufacturers then use various combinations of precipitation and/or chromatography steps to obtain a final preparation that consists of greater than 95 % IgG in all currently available products. The various manufacturers also use different final purification steps and stabilizers to obtain their final products, which may then vary in storage requirement and shelf life. In several currently available products, stabilizers include sugars, such as sucrose, glucose, or maltose. Other products contain amino acids such as glycine and proline. The sodium content of different products also varies.
