Hi there . I am taking 6 puffs of symbicort daily . My doctor wants to add Spireva due to low lung function but I’m concerned about side effects since I’m already on a higher than usual dose of symbicort . He hopes I can back it down to 4 puffs symbicort plus Spireva but if i can’t do that I am concerned about adding the Spireva could be too much medication . Is anybody out there on 6 puffs of symbicort plus Spireva ? Any side effects ? Thank you kindly .
