SSNRIs are the most recent class of antidepressants, and they have fewer side effects compared to the drugs in the two previous groups. The effect of these drugs is based on increasing the supply of serotonin, which affects our mood. This group includes Venlafaxine, Duloxetine, Desvenlafaxine.
Fluoxetine (Prozac) was the first drug that won universal recognition: since 1980 it has become the most popular antidepressant in the world. It is easy to use (usually one tablet a day is enough) and it does not lead to overdose.
Venlafaxine is an antidepressant with a new chemical structure that can not be attributed to tricyclic, tetracyclic or other known antidepressants.
SSNRIs are good not only at combating depression; they also help to cope with some other unpleasant manifestations, ranging from overeating and ending with obsessive conditions.
Although this group of drugs has fewer side effects and they are not that pronounced, nevertheless, they exist. The most common are anxiety, excitement, insomnia, headaches, nausea and diarrhea. Unlike the other groups of antidepressants that can cause weight gain, with SSNRIs a person usually loses in weight a little. SSNRIs are not recommended for people with liver problems.
