A high fever in an 8-month-old baby should be carefully monitored, especially if vomiting prevents the medicine from staying down. Lotemp syrup contains paracetamol, which is commonly used to reduce fever in infants. Sometimes babies may vomit because of the taste, stomach irritation, or the illness itself, rather than the medicine alone. If your daughter vomits immediately after taking the syrup, you should speak to a paediatrician before giving another dose. Doctors may sometimes recommend paracetamol suppositories, which are placed in the rectum and can help when a child cannot keep oral medicine down. In some cases, ibuprofen may be considered for babies older than 6 months, but the dose must be based on the child?s weight and medical condition, so it should only be given after medical advice. Meanwhile, keep her well hydrated with breast milk, formula, or small amounts of fluids frequently. Dress her in light clothing and avoid overwrapping. Seek medical care immediately if the fever is very high, lasts more than a day or two, or is associated with breathing difficulty, poor feeding, excessive sleepiness, seizures, rash, or repeated vomiting.
