Albuterol Also indexed as: Albuterol Inhaled, Proventil, Ventolin
Albuterol is a short-acting, beta-adrenergic bronchodilator drug used for relief and prevention of bronchospasm. It is also used to prevent exercise-induced bronchospasm. While albuterol is available in tablet form, it is most commonly used by oral inhalation into the lungs.
Summary of Interactions with Vitamins, Herbs, and Foods
In some cases, an herb or supplement may appear in more than one category, which may seem contradictory. For clarification, read the full article for details about the summarized interactions.
 May Be Beneficial: Depletion or interference—The medication may deplete or interfere with the absorption or function of the nutrient. Taking these nutrients may help replenish them. | Calcium* Magnesium* Phosphate* Potassium* |
| May Be Beneficial: Supportive interaction—Taking these supplements may support or otherwise help your medication work better. | Coleus* |
 Check: Other—Before taking any of these supplements or eating any of these foods with your medication, read this article in full for details. | Digitalis |
| Side effect reduction/prevention | None known |
| Reduced drug absorption/bioavailability | None known |
| Adverse interaction | None known |
An asterisk (*) next to an item in the summary indicates that the interaction is supported only by weak, fragmentary, and/or contradictory scientific evidence.
Interactions with Dietary Supplements
Minerals
Therapeutic amounts of intravenous salbutamol (albuterol) in four healthy people were associated with decreased plasma levels of calcium, magnesium, phosphate, and potassium.1 Decreased potassium levels have been reported with oral,2 intramuscular, and subcutaneous albuterol administration.3 How frequently this effect occurs is not known; whether these changes are preventable through diet or supplementation is also unknown.
Interactions with Herbs
Digitalis (Digitalis lanata, Digitalis purpurea)
Digitalis refers to a family of plants (commonly called foxglove) that contain digitalis glycosides, chemicals with actions and toxicities similar to the prescription drug digoxin.
In a small study of salbutamol (albuterol) in people receiving digoxin, albuterol was associated with decreased serum digoxin levels.4 No interactions between albuterol and digitalis have been reported. Until more is known, albuterol and digitalis-containing products should be used only under the direct supervision of a doctor trained in their use.
Coleus
A test tube study demonstrated that the bronchodilating effects of salbutamol (albuterol) were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii.5 The results of this preliminary research suggest that the combination of forskolin and beta-agonists such as albuterol might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with albuterol without the supervision of a doctor.
Interactions with Foods and Other Compounds
Food
Albuterol may be taken with food to prevent stomach upset.6
