Symbicort Turbuhaler 160 mcg/4.5 mcg is a prescription inhaler with a higher dose of Budesonide (compared to the 80 mcg formulation), combined with Formoterol, used for the regular treatment of asthma and COPD. Due to the potent combination and higher steroid content, this inhaler requires a valid doctor's prescription and careful instruction on its use. Consult your physician to determine if this higher-strength Symbicort Turbuhaler is appropriate for your respiratory condition.
