This causes more serotonin to be available to transmit messages between the neurons in the brain. Fluvoxamine can not be used in the treatment of covid patients, because it leads to some side effects that can worsen a patients condition if they have covid. These side effects include headache, drowsiness, dizziness, nausea and diarrhea, nervousness and loss of appetite.
