 The key significance of this study is the analysis of the effect that cyproheptadine has on stimulating weight gain and improving behaviors associated with feeding. In addition, it will help give clear comparison between the use of continuous versus cycled cyproheptadine. Cyproheptadine has been suspected to have tachyphylaxis after a couple weeks and many practitioners implement cycling of medication without clear evidence supporting this practice. Investigators expect after this study to be able to design a protocol regarding use of cyproheptadine in feeding team patients.
