Quick Answer
SSRIs and SNRIs — the first-line medications for anxiety — typically take 4 to 6 weeks to reach full effect, with some improvement noticeable in the first 2 to 3 weeks. Buspirone is similar. Beta-blockers and hydroxyzine work within hours when taken as needed. We schedule a follow-up at 2 to 4 weeks after starting any new medication so we can adjust the dose, manage side effects, or switch medications if needed.
