Ibuprofen is an effective and safe treatment for febrile children. Until recently ibuprofen was available only in tablets suspension and as a liquid gel. All these dosage form are administered orally. Rectal suppositories are often essential for treating febrile children who cannot take medications by mouth (e.g vomiting). In the current study we aim to compare the effect on fever of ibuprofen given as suspension with ibuprofen suppositories.
