Question 1

Is Viibryd an SSRI?

Accepted Answer

Yes, Viibryd is classified as a selective serotonin reuptake inhibitor (SSRI). SSRIs work by increasing the level of serotonin, a brain chemical that is believed to influence mood, in your body. The exact mechanism of how Viibryd works isn’t fully understood. What makes Viibryd distinct from other SSRIs is its additional action on serotonin receptors. These receptors are like docking stations on the surface of cells where serotonin can attach. By binding to these receptors, Viibryd mimics the action of serotonin. This dual action is thought to help balance serotonin levels in the brain more effectively. Due to these unique properties, Viibryd is also considered a miscellaneous antidepressant, slightly different from typical SSRIs.

Question 2

Is Viibryd a controlled substance?

Accepted Answer

No, Viibryd is not classified as a controlled substance. Controlled substances are drugs that are subject to stricter regulations due to their potential for misuse, dependence, or addiction. Viibryd does not fall into this category, meaning it is regulated like other regular prescription medications rather than requiring the additional restrictions that apply to controlled substances.

Question 3

Is weight gain a side effect of Viibryd?

Accepted Answer

Weight gain is not commonly reported as a side effect by people taking Viibryd, according to clinical studies. However, like many antidepressants, Viibryd can potentially cause changes in appetite, which may lead to weight gain or weight loss. It’s important to note that while Viibryd does not frequently cause weight gain, individual reactions can vary. Some antidepressants, such as Remeron (mirtazapine), are more likely to lead to weight gain compared to others. If you are concerned about weight changes while taking Viibryd, it’s a good idea to discuss this with your doctor. They can help you manage any potential weight changes by reviewing and possibly adjusting your diet and exercise routine.

Question 4

Does Viibryd cause any sexual side effects?

Accepted Answer

Yes, Viibryd can cause sexual side effects, as reported in clinical studies. These side effects may include erectile dysfunction, changes in orgasm, decreased sex drive, and abnormal ejaculation. During the studies, up to 4% of individuals taking Viibryd experienced these issues, compared to up to 1% of those who received a placebo (a treatment without any active medication). Sexual side effects are relatively common with antidepressants and can also occur with medications used for treating depression and anxiety. However, some antidepressants, such as bupropion (Wellbutrin XL) and mirtazapine (Remeron), are generally associated with fewer sexual side effects. If you are experiencing bothersome sexual side effects while taking Viibryd, it is important to discuss this with your doctor. They can offer treatment options or consider prescribing a different medication that may have a lower risk of these side effects.

Question 5

How long does it take to work?

Accepted Answer

You might not notice significant improvements in your depression symptoms immediately after starting Viibryd. Typically, it can take about 2 to 4 weeks for you to start feeling better, though the timing can vary from person to person. Sometimes, others might notice improvements in your symptoms before you do. If you find your symptoms worsening or experience changes in thinking or mood after beginning treatment with Viibryd, it is crucial to discuss these changes with your doctor.

Question 6

Is Viibryd safe for older adults who have depression?

Accepted Answer

Yes, Viibryd is approved for treating major depressive disorder (MDD) in adults, including those who are older. However, older adults might be more susceptible to certain side effects compared to younger individuals, such as hyponatremia—a condition characterized by low sodium levels in the blood. Symptoms of hyponatremia include dizziness, weakness, and headaches, and these can be serious. While the dosing recommendations for Viibryd are generally the same for older adults as for younger adults, it is advisable for older adults to start with a lower dose. The dose can then be adjusted slowly if needed, based on how well the initial dose is tolerated.
