Almost any kind of antidepressants may cause anxiety, particularly in the initial stage of treatment.
This can be related to the effects of a hormone called serotonin. Low serotonin is believed to play a key role in triggering anxiety and depression.
Moreover, the change of serotonin levels at the beginning of treatment can make some people feel anxious.
Apart from anxiety, some patients may experience the following symptoms: insomnia, anger, aggression, excitement, concern and impulsivity. There are also some rare (but very severe) symptoms like mania, severe depression, and suicidal tendencies. Kids, teenagers, and young people seem to be especially prone to this kind of symptoms.
However, most patients experience only mild anxiety during the treatment. Moreover, it will probably disappear as your body gets adjusted to the treatment.
If you think that your medication is too powerful or if you don’t note any improvements – particularly if you note such symptoms as mania, aggravated depression or suicidal tendencies – contact your doctor immediately.
Never stop the treatment without your doctor’s approval. If you quit the drug suddenly, it can cause pain in the muscles, sickness and weakness. Your doctor can recommend you the best way to avoid these complications.
