Women metabolize zolpidem significantly slower than men, resulting in 50% higher serum levels and increased risk of next-day impairment, necessitating a halved recommended dosage for women.
If you are a woman prescribed zolpidem (Ambien), ensure your doctor prescribes the lower, FDA-recommended dose (typically 5mg). This is because your body clears the drug more slowly than men's, leading to higher levels in your blood and a higher risk of next-day drowsiness or impairment. Do not assume the standard male dose is appropriate for you.
This change in dosing was based on the discovery that women metabolized the same dose of zolpidem slower than men resulting in 50% higher serum levels.
Why this rating
Based on a cited study (Ref 23) regarding pharmacokinetics, supported by FDA action, though the paper itself is a review.
