Escitalopram Administration: With or Without Food
Escitalopram can be taken either with or without food, as stated in the FDA drug label. 1
Administration Guidelines
The FDA-approved labeling for escitalopram clearly states that "Escitalopram tablets should be administered once daily, in the morning or evening, with or without food." 1 This flexibility in administration provides convenience for patients taking this medication for conditions such as major depressive disorder or generalized anxiety disorder.
Key Points About Administration:
- Can be taken at any time of day (morning or evening)
- Food does not affect the absorption or bioavailability of escitalopram
- The absorption of escitalopram is not affected by food intake 2, 3
Pharmacokinetic Considerations
Escitalopram has favorable pharmacokinetic properties that support this flexible dosing approach:
- Rapid absorption with maximum plasma concentrations reached in approximately 3-4 hours
- High bioavailability of approximately 80% that is not affected by food 2
- Long elimination half-life of 27-33 hours, allowing for once-daily dosing 2
- Steady-state concentrations are achieved within 7-10 days of administration 2
Special Considerations
While escitalopram can be taken with or without food for most patients, there are some situations where timing may matter:
- For patients experiencing nausea: Taking escitalopram with food may help reduce gastrointestinal side effects 4
- For patients with sleep disturbances: Timing of dose (morning vs. evening) may be adjusted based on whether the medication causes insomnia or drowsiness 4

Common side effects of escitalopram include:
- Nausea

Taking the medication with food may help manage some gastrointestinal side effects, although this is not required for drug absorption or effectiveness.
