What side effects do you have from switching from buspirone to Lexapro?

That’s a good question. I had brain zaps, nausea, and some pretty bad insomnia. The brain zaps and nausea were managed and after a few weeks diminished, but the insomnia was ultimately the reason I had to discontinue lexapro. My doctor had me lower the dose down to 5mg (cutting a 10mg tablet in half) and I still could not sleep. I have a good number of friends (who I’ve met through an anxiety support group) that take lexapro successfully. Most of them said their biggest side effect was drowsiness! So everyone responds differently. I went back to Buspirone and upped the dosage. I hope this helps! Good luck to you!

Hi, Monica!
If you have side effects at all from starting the Lexapro the most common would be: diarrhea, drowsiness, headache, insomnia, nausea, or dizziness. These can usually be managed with OTC remedies that your pharmacist can recommend and generally subside over just days to a week or so.
A problem might be that starting an antidepressant/anxiolytic can potentially cause increased anxiety for a short initial period of time. Let your doctor know about this and any other side effects.
You should get a Patient Information sheet with your prescription that will detail the possible side effects. Don't worry... you won't have them all or even many!
Best regards and I hope you do well.
