Hello,
You do not need to worry. Taking mirtazapine 7.5 mg for just one isolated night and then starting escitalopram 10 mg after a 3-day gap is safe and commonly done in clinical practice.
Although mirtazapine has a relatively long half-life, a single low dose does not lead to meaningful accumulation in the body. By 3 days, the drug level would already be very low and clinically insignificant.
There is no harmful interaction between mirtazapine and escitalopram in this situation, and no concerning effect on
liver enzymes or drug clearance from this sequence.
Next Steps
• Continue escitalopram exactly as prescribed
• No need to stop or delay the medication
• Observe for common early SSRI side effects (mild nausea, headache, sleep changes), which usually settle in 1-2 weeks
• Follow up with your doctor as advised
Health Tips
• A washout period is mainly important when switching from MAOIs, not in this case
• Avoid frequent Googling about half-life- it often increases anxiety without clinical benefit
• Do not add or stop medicines on your own without consulting your doctor
