Is a worse mood after taking pregabalin a cause for concern?

The first effects of the therapeutic effect of drugs containing pregabalin usually appear after 3-4 weeks of regular use. A dozen or so days of admission is definitely too early to determine the results of therapy. Some symptoms of mental disorders may intensify at the beginning of therapy, but there may also be other symptoms mentioned by you, such as dementia, strange mood, fatigue, lack of willingness to act, drowsiness or difficulty in thinking. Usually, these symptoms are transient and pass with the onset of the effect of the drug.
