Lexapro Or Celexa: What Statistics Says

Before taking any drug, patients need to know how effective they are. Celexa and Lexapro are not an exception. Comparing Celexa vs Lexapro relative efficacy, research has shown that escitalopram is significantly more effective than citalopram in overall depression treatment effects, as a percent of remissions is much lower. Another study examining the treatment of new episodes of major depression has revealed that escitalopram seems to be dominant in the treatment of new major depression occurrences when compared to citalopram. The reason for such a conclusion was higher remission rates and lower total costs of Lexapro. Also, it is worth noting that citalopram side effects are more prevalent than escitalopram ones.

Medical Administration Is Important

Both escitalopram and citalopram have been proven to be excellent remedies for depression and related conditions. However, before taking each of them, a doctor’s consultation is required. Users should understand what citalopram is and what escitalopram medication is. At the same time, if a patient misuses any of the two drugs, an overdose may happen. Thus, it is strongly recommended that a victim visits a professional rehabilitation and addiction centers as soon as possible.
