Esram (Escitalopram)
+ BONUS
 
Escitalopram

Esram is used to treat depression. It belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). They are thought to work by their actions on brain chemicals called amines which are involved in controlling mood. Depression is longer lasting or more severe than the "low moods" everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing. Esram corrects this chemical imbalance and may help relieve the symptoms of depression. Esram may also be used to treat patients who may avoid and/or are fearful of social situations. Esram may also be used to treat patients who have excessive anxiety and worry. Esram may also be used to treat irrational fears or obsessional behaviour (obsessive-compulsive disorder). Obsessive-compulsive disorder involves having both obsessions and compulsions. Obsessions are unwanted thoughts that occur over and over again. Compulsions are the ongoing need to repeat certain actions as a result of these thoughts. Your doctor, however, may prescribe it for another purpose. Ask your doctor if you have any questions about why it has been prescribed for you. This medicine is only available with a doctor's prescription. Esram is not addictive. However, if you suddenly stop taking it, you may get side effects.
