Question
A 60-year-old client is starting dabigatran 150 mg orally twice daily for non-valvular atrial fibrillation. Which instruction about storage and administration is correct?
1Open the capsule and sprinkle the contents on apple sauce for easier swallowing.
2Refrigerate the capsules to prolong shelf life.
3Transfer the capsules to a weekly pill organizer for convenience.
4Store the capsules in the original bottle or blister pack with the desiccant; keep the bottle tightly closed; once opened, use the contents within 4 months and discard any unused capsules; swallow the capsule whole with water — do NOT break, chew, open, or crush.✓ Correct answer
Explanation
Dabigatran — humidity-sensitive capsule Dabigatran etexilate (Pradaxa) is a direct thrombin inhibitor pro-drug formulated as a capsule containing tartaric acid pellets. The drug is extremely sensitive to moisture; once exposed to humidity it loses potency rapidly, and breaking, chewing, opening, or crushing the capsule increases bioavailability ~75% and dramatically raises bleeding risk.
Storage and administration rules: • Keep capsules in the original manufacturer bottle (with desiccant) or blister pack. The desiccant absorbs moisture. • Keep the bottle tightly closed at room temperature, away from moisture. • Once opened, use within 4 months; discard any remaining capsules at 4 months. • Do NOT transfer to a pill organizer or other container — moisture exposure ruins the drug. (Other capsules can be transferred; dabigatran is the exception.) • Swallow whole with water. Do NOT break, chew, open, or crush — opening doubles bioavailability and causes severe bleeding. • Do NOT refrigerate.
Other key teaching: • 150 mg BID is standard for stroke prevention in afib; 75 mg BID for CrCl 15–30 (but generally avoided if CrCl
