Desvenlafaxine is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar. [18]
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 ...
[11] [59] [72] The two common sexual side effects are diminished interest in sex (libido) and difficulty reaching climax , which are usually somewhat milder with SNRIs compared to SSRIs. [73] To manage sexual dysfunction, studies have shown that switching to or augmenting with bupropion or adding a PDE5 Inhibitor have decreased symptoms of ...
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]
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 ...
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.
Routine use of colonoscopy screening varies globally. In the US, colonoscopy is a commonly recommended and widely utilized screening method for colorectal cancer, often beginning at age 45 or 50, depending on risk factors and guidelines from organizations like the American Cancer Society. [9] However, screening practices differ worldwide.
