Escitalopram (Lexapro) Equivalent for Paroxetine (Paxil) 10 mg
An adult dose equivalence for switching from paroxetine 10 mg daily to escitalopram 5 mg daily is shown in a switching-dose table that lists paroxetine 40 mg as targeting escitalopram 20 mg. [1]
Dose Equivalence Calculation
- Paroxetine 40 mg corresponds to escitalopram 20 mg in the provided switching-dose table. [1]
- Therefore, paroxetine 10 mg corresponds to escitalopram 5 mg (linear proportion based on the same table mapping). [1]
Initiation Thresholds for Switching
- For SSRI-to-SSRI switching without a required washout, cross-taper or sequential titration strategies are typically used based on interaction risk and withdrawal risk, with dose increments guided by switching resources. [2]
Monotherapy vs Combination Therapy During Switch
- Antidepressant switching strategies include stopping the first antidepressant while starting the second at prescribed target doses. [2]
- Cross-tapering strategies may involve overlapping therapy for a short interval using dose increments to reduce discontinuation risk. [2]
Common Pitfalls to Avoid
- Abrupt changes between short half-life SSRIs can increase discontinuation risk. [2]
- Paroxetine has greater discontinuation risk than longer half-life SSRIs, which supports slower, structured switching. [2]
Targets or Goals of Therapy
- The switch target is to reach the established therapeutic dose of the receiving antidepressant using an antidepressant-specific conversion table. [1]
Clinical Safety Note
- Hepatic and renal function normalization reduces dose-adjustment needs, but switching plans should still consider withdrawal history and concurrent interacting medications. [2]
