Albuterol and Potassium, a caution.
Albuterol can temporarily lower serum potassium, especially with repeated nebulizer treatments, continuous therapy, or high-dose use during asthma or COPD exacerbations. This is not true potassium loss from the body; it is a shift of potassium into cells, so symptoms and lab values can change quickly. Risk is higher if your potassium is already low, you use diuretics, or you have heart rhythm disease.

Caution
What is happening. Albuterol can temporarily lower serum potassium, especially with repeated nebulizer treatments, continuous therapy, or high-dose use during asthma or COPD exacerbations. This is not true potassium loss from the body; it is a shift of potassium into cells, so symptoms and lab values can change quickly. Risk is higher if your potassium is already low, you use diuretics, or you have heart rhythm disease.
Mechanism. Beta-2 adrenergic stimulation from albuterol increases cyclic AMP signaling and stimulates sodium-potassium ATPase activity in skeletal muscle. This drives potassium from the bloodstream into cells and can lower measured serum potassium without reducing total-body potassium stores.
Recommendation. Do not try to correct frequent albuterol-related tremor, weakness, or palpitations by increasing potassium supplements on your own. If you are using albuterol repeatedly or continuously, ask for potassium monitoring, especially if you also take diuretics or have heart disease. Seek urgent care for severe weakness, fainting, chest pain, or sustained palpitations.
