Am suffering from asthma. Please advice medicine. Currently, am using symbicort (budesonide and formoterol). Thank you sir.

Type of asthma? Your are currently taking a product that combines a steroid and long acting "beta agonist" and called a "controller". Are you also taking a "rescue" inhaler like albuterol? Have you tried to eliminate the likely "triggers" in your home, car, workplace? This is important. Talk over the "triggers" issue with your physician.
