Long-term treatment of bronchoconstriction associated with COPD, including chronic bronchitis and emphysema.

Long-acting β2-adrenergic agonists recommended as maintenance therapy in patients with moderate (e.g., forced expiratory volume in 1 second [FEV1] ≥50 but <80% of predicted) to very severe COPD (e.g., FEV1 <30% of predicted or <50% of predicted plus chronic respiratory failure) who have persistent symptoms not relieved by as-needed therapy with short-acting bronchodilators (e.g., ipratropium, β2-adrenergic agonist).

Regular treatment with long-acting bronchodilators more effective and convenient than treatment with short-acting bronchodilators. Superiority of one long-acting bronchodilator over another currently not established. If inadequate response, may use a combination of long-acting bronchodilators, such as a long-acting inhaled anticholinergic agent (tiotropium) and a long-acting β2-adrenergic agonist.

In patients with severe (e.g., FEV1 <50% of predicted, history of repeated exacerbations) to very severe COPD, add regular treatment with an inhaled corticosteroid to long-acting bronchodilator therapy. If inadequate response or limiting adverse effects occur, add or substitute extended-release oral theophylline.

Not to be used for immediate relief of acute exacerbations of COPD. Use short-acting inhaled β2-agonist intermittently (as needed) for acute symptoms of COPD. (See Acute Exacerbations of COPD under Cautions.) Efficacy and safety of long-acting bronchodilators, with or without inhaled corticosteroids, during acute exacerbations of COPD not established.

Leucovorin is a form of folic acid (a type of vitamin B). Folic acid helps your body produce and maintain new cells, and also helps prevent changes in DNA that may lead to cancer. A lack of folic acid in the body can cause anemia, a decrease in red blood cells that carry oxygen through your blood to your tissues and organs.

Leucovorin is used to treat anemia (low red blood cells) caused by a lack of natural folic acid in the body.

Leucovorin is also used to prevent serious side effects caused by large doses or accidental overdose of medications that can reduce the effects of folic acid in the body. This includes methotrexate, pyrimethamine, and others.

Leucovorin is sometimes used in a chemotherapy combination to lengthen survival time in people with advanced colorectal cancer. Leucovorin does not treat the cancer itself.

Leucovorin may also be used for purposes not listed in this medication guide.
