Symbicort Turbuhaler is a prescription inhaler containing a combination of budesonide (160mcg) and formoterol (4.5mcg). This inhaler provides 120 doses of inhalation powder used to treat asthma and chronic obstructive pulmonary disease (COPD). The device delivers medication directly to the airways to help control symptoms and prevent flare-ups. The Turbuhaler is a breath-activated dry powder inhaler that does not require a propellant. Each dose contains 160 micrograms of budesonide (an inhaled corticosteroid that reduces inflammation) and 4.5 micrograms of formoterol (a long-acting beta2-agonist bronchodilator that relaxes airway muscles). The inhaler features a dose counter to track remaining medication. The medication should be stored at room temperature away from moisture. This is a prescription-only medication that should be used as directed by a healthcare provider.
