Lexapro to Treat Depression
Lexapro (generic name escitalopram) is used as an oral drug to treat depression as well as GAD or generalized anxiety disorder. The chemical composition of Lexapro is identical to that of citalopram (generic name Celexa). Both Lexapro and Celexa belong to the class of drugs called SSRIs or selective serotonin reuptake inhibitors. There are a few other drugs also in this group, such as Prozac, Paxil, and Zoloft. Lexapro is a prescription drug, and can be effective in treating anxiety and depression in adults as well as teenagers (generally patients over the age of 12 years).
How It Works
The SSRI drugs act upon the neurotransmitters in the brain. The neurotransmitters are chemicals that act as the messengers that help the nerves used to communicate with each other. The neurotransmitters are created and released by the nerves. These neurotransmitters then move to the other nearby nerves. They attach themselves to the receptors on the nerves. All of these neurotransmitters that are released from a nerve do not bind to receptors. These are then taken up by the nerves that created them. This process where a nerve takes back the neurotransmitter that it creates is referred to as re-uptake. It is believed that imbalances of neurotransmitters caused in this way leads to depression. Lexapro acts by preventing the re-uptake of a serotonin, a particular neurotransmitter. This results in the availability of more serotonin to attach to other receptors. Lexapro was approved by FDA in August 2002
Side Effects
Most of the drugs and medications cause side effects. The side effects do not occur to all patients who use the Lexapro medication. A vast majority of the patients are tolerant to the Lexapro drug. In some cases, minor side effects caused by Lexapro may be seen. Most of them do not require treatment; they disappear on their own. Some of the side effects that Lexapro causes are vomiting, sleeplessness, fatigue and tiredness, sweating, and drowsiness. In pediatric patients, the following side effects have been experienced: body ache and back pain, vomiting, chest and nasal congestion, and rarely urinary infection. Sometimes side effects like constipation, diarrhea, dizziness, dry mouth, instability, loss of hunger and tiredness may be experienced.
Lexapro does not cause fatal or serious side effects in most patients. But if any other side effects other that these are experienced, you need to consult your medical practitioner. Lexapro may sometimes cause confusion, loss of memory, hallucination, irritability, skin problems, unusual bleeding, mood swings and suicidal thoughts.
The safety of Lexapro during pregnancy has not yet been established. It is better not to use the drug during pregnancy. Lexapro is excreted in human milk, and so is not advised in breastfeeding mothers.
Certain side effects may accompany the sudden stoppage of Lexapro. Some of the stopping symptoms are sleeping disorders, nervousness, stomach upset, feeling of shock in the arms and dizziness. These severe stopping side effects can be minimized by the slow weaning off of Lexapro, rather than stopping it suddenly. The stopping symptoms may be visible from day one to the tenth day of stopping the dose. Though none of these symptoms are life threatening, seek medical help if you experience any of them.
