Long-term use of disodium cromoglycate in bronchial asthma.

For many patients disodium cromoglycate will retain its usefulness and safety in long-term use. Care should be exercised in employing disodium cromoglycate in chronic corticosteroid users who develop respiratory infection to avoid the development of pneumonia. Disodium cromoglycate may be expected to regain its usefulness following non-use of the drug for varying periods of time.
