Never rely on cromolyn to relieve an active asthma attack or acute bronchospasm.

Test yourself first: 1 question
Question 1 of 1
A nurse is teaching a client prescribed cromolyn sodium by inhalation. Which statement by the nurse is accurate about this medication?
Answer: B. Cromolyn is a mast cell stabilizer used to prevent asthma symptoms and is taken on a regular schedule, including before exposure to a known trigger or exercise. It has no bronchodilator action and cannot relieve an acute attack. It must be used consistently and may take several weeks to reach full effect.
Keep the streak going with more questions like these, each with a full rationale.
What is cromolyn?
It is a preventive controller drug and has NO effect on an acute attack. Effects build over time, so it must be used consistently.
Key points to remember
- It is a prophylactic mast cell stabilizer that prevents, but does not relieve, bronchospasm.
- Full benefit may take 2-4 weeks of regular use.
- It can be taken before exercise or known allergen exposure to prevent symptoms.
- It has a very favorable safety profile with minimal systemic side effects.
- Common minor effects include throat irritation, cough, and bad taste.
Nursing priorities
- Reinforce regular scheduled use rather than as-needed use.
- Teach pre-dosing before exercise or anticipated allergen exposure.
- Continue a separate rescue bronchodilator for acute symptoms.
- Teach mouth rinsing or sipping water to ease throat irritation.
Patient teaching
- Use it on a regular schedule; it may take a few weeks to work fully.
- Take it before exercise or allergen exposure to prevent symptoms.
- Keep your rescue inhaler for sudden attacks because this drug will not stop one.
Red flags: report now
- Never rely on cromolyn to relieve an active asthma attack or acute bronchospasm.
- Report worsening wheezing or difficulty breathing after a dose (possible bronchospasm).
