MRCP2-4245

A 27-year-old female patient has come for a follow-up on her asthma management. She reports that her asthma control has deteriorated lately and she is using her Ventolin inhaler once or twice a week. She confirms that she is not taking any other medication for asthma control. She denies any recent sickness, but she does mention that her symptoms worsen in colder temperatures and during physical activity. What would be the most appropriate course of action to take next?
