If you miss an SSRI dose, you should take it within how many hours?

• A. Within 48 hours
• B. Up to 8 hours after missed dose
• C. 24 hours later
• D. Skip the dose entirely

Answer: (B)

Maintaining steady SSRI levels is essential to keep symptoms controlled and to minimize withdrawal-like effects. If you miss a dose, take it as soon as you remember, but within a short window—about eight hours. This helps prevent the medication level from dropping too far before your next regular dose, preserving therapeutic effect without piling up a double dose. If you’re already close to your next scheduled dose, skip the missed one rather than doubling up, to avoid excessive medication in a short time.

Taking within eight hours balances catching the missed dose with the need to keep overall exposure within a safe range. Waiting longer than that—like 24 or 48 hours—would create a larger gap in coverage and undermine symptom control. Skipping the dose entirely when you’ve already missed a lot negates the benefit of catching up and can lead to worse symptoms or discontinuation effects.
