Difference between Lexapro and Celexa
Lexapro and Celexa are both prescription medications used to treat depression and anxiety disorders. While they are both part of the selective serotonin reuptake inhibitor (SSRI) class of drugs, there are several key differences between the two that can impact their effectiveness and side effects for individual patients.
1. Chemical Structure
Lexapro, also known as escitalopram, is the S-enantiomer of citalopram, which is the active ingredient in Celexa. This means that Lexapro contains only the right-handed isomer of citalopram, while Celexa contains both the right-handed and left-handed isomers. The difference in chemical structure can lead to variations in how the drugs are metabolized and their effectiveness.
2. Dosage
Lexapro typically requires a lower starting dose compared to Celexa. Lexapro’s starting dose is usually 10 mg once daily, while Celexa’s starting dose is often 20 mg once daily. This can be beneficial for patients who may be sensitive to medication side effects or who need a more gradual increase in treatment.
3. Onset of Action
Lexapro tends to have a faster onset of action compared to Celexa. While both medications can take several weeks to reach full effectiveness, Lexapro may start to have an impact on symptoms sooner than Celexa. This can be an important factor for patients who are experiencing severe symptoms or who need relief quickly.
4. Side Effects
Both Lexapro and Celexa can cause similar side effects, such as nausea, dry mouth, and sexual dysfunction. However, some patients may experience more pronounced side effects with one medication over the other. It is essential for patients to discuss their side effect profiles with their healthcare provider to determine which medication may be more suitable for their needs.
5. Cost
The cost of Lexapro and Celexa can vary depending on the pharmacy and insurance coverage. In some cases, Lexapro may be more expensive than Celexa due to its specific chemical structure and patent protection. Patients should consider their budget and insurance coverage when choosing between the two medications.
Conclusion
In summary, the difference between Lexapro and Celexa lies in their chemical structure, dosage, onset of action, side effects, and cost. While both medications are effective for treating depression and anxiety disorders, individual patient preferences and specific needs may influence the choice between Lexapro and Celexa. It is crucial for patients to consult with their healthcare provider to determine the most appropriate treatment option for their unique situation.
