It's understandable to be concerned after accidentally giving an incorrect dose of medication. Budicort (budesonide) is an inhaled corticosteroid, and while giving an entire 5-respule dose (2.5 mg in total) is significantly higher than the typical single dose for an infant, it's reassuring that your baby has taken normal feeds and is sleeping well without any immediate side effects. In most cases, a one-time higher-than-normal dose of budesonide is unlikely to cause severe harm, but it’s essential to monitor your baby closely for any signs of potential side effects such as: Increased irritability or unusual sleepiness Changes in breathing patterns or difficulty breathing Vomiting or a decrease in feeding
