Yes, these medications are safe and appropriate. Ondansetron controls vomiting, Lansoprazole reduces stomach acid to soothe throat or stomach irritation (which often causes tiny streaks of blood during forceful vomiting), and Paracetamol manages the fever. Precautions to take: 1. Keep your baby hydrated by offering frequent, very small sips of oral rehydration solution (ORS), breastmilk, or formula. 2. Follow the exact dosages prescribed by your pediatrician. 3. Monitor closely: seek immediate medical care if you notice signs of dehydration (like no wet diapers for 6 hours, dry mouth, or no tears when crying), extreme lethargy, or if the vomiting or blood worsens.

A temperature of 99.9 degrees F is a low-grade fever and usually does not require medication unless your child is uncomfortable. Giving Crocin (paracetamol) every 4 hours is too frequent and risks liver toxicity. Do not increase the dose. If your child is distressed and an alternative is needed, Ibuprofen suspension can be considered, but only after consulting your pediatrician to get the correct dosage based on your child's weight. For now, keep your child hydrated, dress them in light clothing, and use lukewarm water sponging. Please visit your pediatrician before switching medications to ensure safety.
