I am giving azithral 200 and piriton and maxtra, should i continue this or and this medicine combination is perfect for treatment? [/INST] Hey there, Thank you for your question and welcome to Chat Doctor. First off, why is your daughter having difficulty breathing? Is it due to the nasal congestion or because her tonsils are enlarged? The sound that she makes while sleeping could be due to the stuffy nose. She is having to compensate for air so she's mouth breathing. You are probably also hearing chest congestion if she has a cold. If you hear a high pitch whistle sound called wheezing, then I would recommend a visit back to the doctor to make sure her airway isn't being affected by her swollen tonsils. The medications that you listed are exactly what I would want to see given to her. Strep throat is treated with antibiotics and that is what the literal is for. Remember, with any antibiotics, it will take 2-3 days before her symptoms start to resolve. The fever, sore throat and ulcers will usually still be present during the first 24-36 hours. The two other medications you listed are to make her comfortable in terms of her nasal congestion and other cold symptoms. I would have to agree with the doctor who prescribed the medications and say that it is a good treatment plan. Hopefully your little one will start to feel better quickly. Have a good day! </s>
