A nurse teaches a client using a tiotropium HandiHaler. Which instruction is most important?

1 Use this inhaler twice daily as needed for shortness of breath
2 Chew the capsule before using the inhaler
3 Inhale the powder once daily; do not swallow the capsule and rinse the mouth afterward ✓ Correct answer
4 Mix the capsule contents with juice and drink the solution

Explanation

Correct (2): Tiotropium HandiHaler capsules are inhaled only, never swallowed. Place the capsule in the device, pierce it, then inhale forcefully (forceful for DPI, unlike MDI). Once-daily controller dosing. Rinse mouth to reduce anticholinergic dry mouth. (1) Not BID/PRN. (3,4) Capsules are for inhalation, not oral.

In-depth explanation

Memory Tip Tiotropium = "Once-daily, Inhale-only, Anti-Spit (dry mouth)." DPI requires FORCEFUL inhalation; MDI requires SLOW deep inhalation. Caution Use spacer with MDI, not with DPI.

Clinical scenario

Scenario 70-year-old female with COPD newly prescribed tiotropium 18 mcg via HandiHaler once daily. First-time teaching with DPI device.

Long-acting muscarinic antagonist (LAMA) — Tiotropium, umeclidinium, aclidinium, glycopyrronium; daily COPD bronchodilator.
HandiHaler device — Single-capsule DPI requiring forceful inhalation; capsule is pierced before use.
DPI vs MDI technique — DPI: forceful fast inhalation. MDI: slow deep inhalation. Spacer used with MDI only.
