Side Effects


Tilade (nedocromil inhalation aerosol) is generally well tolerated. Adverse event information was derived from 6,469 patients receiving Tilade (nedocromil inhalation aerosol) in controlled and open-label clinical trials of 1-52 weeks in duration. A total of 4,400 patients received two inhalations four times a day. An additional 2,069 patients received two inhalations twice daily or another dose regimen. Seventy-seven percent of patients were treated with Tilade (nedocromil inhalation aerosol) for eight weeks or longer.

Of the 4,400 patients who received two inhalations of Tilade (nedocromil inhalation aerosol) four times a day, 2,632 were in placebo-controlled, parallel trials and of these 6.0% withdrew from the trials due to adverse events, compared to 5.7% of the 2,446 patients who received placebo.

The reasons for withdrawal were generally similar in the Tilade (nedocromil inhalation aerosol) and placebo-treated groups, except that patients withdrew due to bad taste statistically more frequently on Tilade (nedocromil inhalation aerosol) than on placebo. Headache reported as severe or very severe, some with nausea and ill feeling, was experienced by 1.0% of Tilade (nedocromil inhalation aerosol) patients and 0.7% of placebo patients.

The events reported with a frequency of 1% or greater across all placebo-controlled studies are displayed for all patients ages 6 years and older who received Tilade (nedocromil inhalation aerosol) or placebo at two inhalations four times daily.

The adverse event profile observed in children ages 6 through 11 was similar to that observed in adults.

Other adverse events present at less than the 1% level of occurrence, but that might be related to Tilade (nedocromil inhalation aerosol) administration, include arthritis, tremor, and a sensation of warmth. In clinical trials with 2,632 patients receiving Tilade (nedocromil inhalation aerosol) , 2 patients (0.08%) developed neutropenia and 3 patients (0.11%) developed leukopenia. Although it is unclear if these reactions were caused by Tilade (nedocromil inhalation aerosol) , in several cases these abnormal laboratory tests returned to normal when Tilade (nedocromil inhalation aerosol) was discontinued.

There have been reports of clinically significant elevation of hepatic transaminases (ALT and AST greater than 10 times the upper limit of the normal reference range in one patient) associated with the administration of Tilade (nedocromil inhalation aerosol) . It is unclear if these abnormal laboratory tests in asymptomatic patients were caused by Tilade (nedocromil inhalation aerosol) .

Cases of bronchospasm immediately following dosing with Tilade (nedocromil inhalation aerosol) have been reported from postmarketing experience. (See WARNINGS.) Isolated cases of pneumonitis with eosinophilia (PIE syndrome) and anaphylaxis have also been reported in which a relationship to drug is undetermined.

In clinical studies, Tilade (nedocromil inhalation aerosol) has been co-administered with other anti-asthma medications, including inhaled and oral bronchodilators, and inhaled corticosteroids, with no evidence of increased frequency of adverse events or laboratory abnormalities. No formal drug-drug interaction studies, however, have been conducted.

This monograph has been modified to include the generic and brand name in many instances.
