Giving 0.3 ml of Asthalin Respiratory Solution twice a day to your 10-month-old baby is usually safe when prescribed by a paediatrician based on your baby’s weight, health, and breathing condition. It is vital not to change the dose or give the medicine on your own. Give it exactly as instructed and watch for side effects such as shaking, fast heartbeat, or unusual fussiness. If you notice any of these, contact your doctor immediately.
