Can a Patient Take Lexapro During a 12-Hour Fast?
Yes, patients can and should take Lexapro (escitalopram) during a 12-hour water and food fast, as the medication can be taken with or without food and does not require specific timing related to meals. 1
Medication Administration Guidelines
- The FDA label explicitly states that "Escitalopram tablets may be taken with or without food," confirming that fasting status does not affect appropriate administration 1
- Food does not affect the absorption of escitalopram, as the drug is rapidly absorbed regardless of meal timing, reaching maximum plasma concentrations in approximately 3-4 hours 2
- Escitalopram should be administered once daily, either in the morning or evening, with the timing based on patient preference rather than food intake 1
Fasting Context Considerations
- For standard laboratory fasting (such as for lipid panels or glucose testing), the American Society of Anesthesiologists confirms that oral medications via non-nourishing routes are generally permitted during fasting periods 3
- A 12-hour fast for laboratory work is standard and does not contraindicate routine medication administration 4
- Water intake is freely permitted during fasting periods and should be encouraged to facilitate medication administration 4
Important Caveats
- Do not discontinue Lexapro abruptly even for a fasting period, as the FDA label warns that "symptoms associated with discontinuation of Escitalopram tablets and other SSRIs and SNRIs have been reported" 1
- If the patient has concerns about taking medications during their specific fasting protocol (such as religious fasting), they should consult their prescribing physician, but from a pharmacological standpoint, there is no contraindication 1
- The medication has a half-life of 27-33 hours, making it consistent with once-daily dosing and meaning that missing even a single dose could disrupt steady-state concentrations 2
Practical Implementation
- Take the Lexapro at the usual scheduled time with plain water during the 12-hour fast 1
- Plain water consumption does not break a laboratory fast and is recommended to facilitate medication administration 4
- Continue the medication without interruption to maintain therapeutic blood levels and avoid withdrawal symptoms 1
