    Symbicort Inhaler Dosage and Side Effects

    Symbicort Inhaler (Budesonide/Formoterol) is a prescription medication that is used to treat asthma and Chronic Obstructive Pulmonary Disease (COPD).

    There are two active ingredients in Symbicort called budesonide and formoterol. The budesonide belongs to a family of medication called inhaled corticosteroids which work to decrease inflammation in the lungs. Formoterol helps to relax and open the airways which allows you to breather more comfortably. Both of these active ingredients aim to provide 24-hour coverage to prevent and relieve COPD symptoms like shortness of breath.

    To buy Symbicort Inhaler online, or even generic Symbicort, a prescription must be submitted to process your order. There are two  dosage forms available: Symbicort 80/4.5 mcg and Symbicort 160/4.5 mcg. Both of these inhalers are manufactured by AstraZeneca.

    There are 120 doses in each inhaler and the usual 3 month supply is 360 doses. To help save on Symbicort price, be sure to use coupon code SYM20 to save an additional $20 on your order from our trusted Canadian Pharmacy.
