Yes, there are products available at pharmacies that could help with eczema in infants. It is recommended to speak to a pharmacist to see if there are any suitable options for treating the dry and red patches on your 5-month-old child. If the current cream you are using does not show improvement in 3 weeks, you may need a product that contains a small amount of corticosteroids. It's important to seek professional advice to ensure the best treatment for your child's condition.
