Headache — an often transient side effect that is common to most serotonin reuptake inhibitors and that most often occurs at the beginning of therapy or after a dose escalation. Nausea — an adverse effect that is more common with venlafaxine than with the SSRIs. Usually transient and less severe in those receiving the extended release ...
Some side effects, such as weight gain, occur more frequently with certain types of antidepressant medication. Switching to a new type of antidepressant may help reverse any weight gain you’ve ...
Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin–norepinephrine reuptake inhibitor (SNRI) class. [6] [9] It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. [9]
The drug — used to treat depression and seasonal affective disorder and help people stop smoking — has also been shown to stimulate the central melanocortin system, which regulates appetite ...
These drugs inhibit the uptake of the neurotransmitter 5-HT by blocking the SERT, thus increasing its synaptic concentration, and have shown to be efficacious in the treatment of depression, however sexual dysfunction and weight gain are two very common side-effects that result in discontinuation of treatment.
Unfortunately, these medications are associated with significant neurotoxicities. Psychiatric medications carry risk for neurotoxic adverse effects. The occurrence of neurotoxic effects can potentially reduce drug compliance. Some adverse effects can be treated symptomatically by using adjunct medications such as anticholinergics (antimuscarinics).
Some of the most common naturally occurring brain toxins that lead to neurotoxicity as a result of long term drug use are amyloid beta (Aβ), glutamate, dopamine, and oxygen radicals. When present in high concentrations, they can lead to neurotoxicity and death . Some of the symptoms that result from cell death include loss of motor control ...
Further, they have fewer and milder side effects. Tricyclic antidepressants also have a higher risk of serious cardiovascular side effects, which SSRIs lack. SSRIs act on signal pathways such as cyclic adenosine monophosphate (cAMP) on the postsynaptic neuronal cell, which leads to the release of brain-derived neurotrophic factor (BDNF). BDNF ...
