Fosrenol (lanthanum) prevents the body from absorbing phosphate, allowing it to be removed from the body.

Fosrenol is used to lower phosphate levels in patients with end stage kidney disease. High levels of phosphate can make it hard for your body to absorb calcium, which can cause serious medical problems.

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

Symptomatic management of bronchospasm in patients with reversible, obstructive airway disease (e.g., asthma). Manufacturer recommends against use with other β-adrenergic bronchodilators. (See Specific Drugs under Interactions.)

Current asthma management guidelines and most clinicians recommend anti-inflammatory therapy with an orally inhaled corticosteroid as first-line therapy for long-term control of persistent asthma, supplemented by intermittent, as-needed use of a short-acting, inhaled β2-agonist.

The National Asthma Education and Prevention Program (NAEPP) does not recommend nonselective β-adrenergic agonists, including metaproterenol, for treatment of asthma because of the associated potential for excessive cardiac stimulation, particularly in high doses.

Symptomatic management of reversible bronchospasm in patients with COPD, including chronic bronchitis and emphysema. Manufacturer recommends against use with other β-adrenergic bronchodilators. (See Specific Drugs under Interactions.)
