Generally Merlin and Cephalexin can be taken together. Because the adverse reactions of cephalosporin and merlin are very small, there are no adverse consequences when the two are applied together. Most of the cephalosporins are first generation cephalosporins or second generation cephalosporins, or even third generation cephalosporins, and their safety is still relatively good. Merrill is composed of ibuprofen, which has a slight effect on liver and kidney function, and has very little effect on children within the normal dose range. In summary, Merlin and cephalosporin can be taken together. Cephalosporin should be taken 2-3 times a day, and Merlin should be taken when necessary. Merlin does not need to be taken three times a day. Only children with body temperature above 38.5℃ under the axilla should take Merlin for symptomatic treatment.
