She's 5.5. Last week we thankfully had a consultant appointment to review her asthma but she's had a cold leading up the appointment which had gone to her chest so he had a listen and said infection. Gave three days of antibiotics and steroids both are finished but her cough is still very wet. Obviously still going with the inhaler/montelukast regime. How long do the antibiotics keep working in the body? Wondering if it's time to call him as she finished them on Friday. Thanks.
