What is Viibryd?

Viibryd is the brand name for the SSRI medication vilazodone. SSRIs help regulate brain chemistry by blocking serotonin receptors and increasing serotonin levels in the brain, which helps regulate a patient’s mood, energy levels, sleep cycles, and appetite.  

Common Doses and Forms of Viibryd

Viibryd comes in color-coded oval tablets with the dosage printed on one side. 

• 10mg red
• 20mg yellow
• 40mg blue

Most individuals start Viibryd by taking 10mg and gradually increasing their dosage to the maximum dosage of 40mg, if necessary. Viibryd should be taken once daily with food. 

Conditions Viibryd Treats

Viibryd is only FDA-approved to treat Major Depressive Disorder (MDD), otherwise known as chronic depression. However, it’s often prescribed off-label to treat anxiety and anxiety-related disorders and conditions. 

Off-Label Uses for Viibryd

Off-label refers to the practice of prescribing medications to treat conditions not approved by the FDA. These medications are considered safe to take; they just haven’t gone through the FDA approval process for every condition they’re able to treat.

For instance, Viibryd is often prescribed off-label for the following: 

• Obsessive-compulsive disorder
• Generalized anxiety disorder 
• Panic disorder

Viibryd Can Treat Symptoms of Depression and Anxiety

Bringing brain chemistry into balance is one of the most effective ways to treat depression and anxiety. Low serotonin levels can cause opposing symptoms, such as:

• Extreme fatigue or manic nervousness
• Apathy or panic attacks
• Extreme exhaustion or insomnia
• Disinterest in food or nervous nausea

Each set of symptoms can result from depression and/or anxiety. Raising serotonin levels in the brain helps reset its natural rhythms and reactions to alleviate these symptoms. 

Viibryd Costs

Brand name Viibryd costs much more than generic vilazodone. They’re the same medication with different branding, so it’s more cost-effective to ask for the generic prescription, especially if you don’t have adequate health insurance. 

For instance, 30 days’ worth of Viibryd can cost over $340, while the same amount of vilazodone costs around $15. 

Viibryd Side Effects

Viibryd has fewer side effects than most other SSRIs, meaning many patients tolerate it better than other drugs in the same class. Some of its common side effects include: 

• Nausea
• Vomiting
• Diarrhea
• Insomnia
• Sexual dysfunction

Less common but more serious side effects may arise if you develop a condition called serotonin syndrome, which is potentially fatal. This condition occurs when your brain is overloaded with serotonin. If you experience any of the following symptoms, seek medical attention immediately: 

• Seizures
• Blurred or tunnel vision
• Eye pain, swelling, or seeing halos around lights
• Easy bruising or unusual bleeding
• Racing thoughts or unusual risk-taking behavior
• Decreased inhibitions, euphoria, or extreme sadness
• Headache or severe weakness
• Confusion or slurred speech
• Loss of coordination or feeling unsteady

Viibryd Warnings

People with certain conditions should not take Viibryd because it could make those conditions worse or interact with the medications used to treat them. These conditions include: 

• Liver or kidney disease
• Bleeding or blood clotting disorders
• Narrow-angle glaucoma
• Epilepsy
• Bipolar disorder
• Sexual function issues
• A history of drug addiction
• Suicidal thoughts

Viibryd Drug Interactions

Some medications may interact poorly with Viibryd and create an increased risk of serious health problems. Those who take the following medications should avoid taking Viibryd: 

• Monoamine oxidase inhibitors (MAOIs)
• Pimozide or other Tourette’s syndrome medications
• Thioridazine or other antipsychotic medications
• Stimulant medications, like Adderall
• Opioid-based painkillers
• Herbal supplements, such as St. John’s Wort
• Tryptophan

What is Luvox?

Luvox is the brand name for an SSRI medication called fluvoxamine. Similar to Viibryd, Luvox boosts serotonin levels in the brain by preventing certain receptors from transferring it to the bloodstream. This process helps relieve the symptoms of depression, anxiety, and other conditions related to mood and brain chemistry.  

Common Doses and Forms of Luvox 

Both brand name Luvox and generic fluvoxamine are white tablets that come in a blister pack. Brand name Luvox tablets are oval, while fluvoxamine is round. Each kind is available in the following dosages: 

• 25mg
• 50mg
• 100mg

When taking Luvox, you can choose between immediate-release (IR) tablets or extended-release (ER) capsules. Adults over 18 typically start on 50mg and can gradually increase their dose over several weeks up to 300mg per day, if needed.

Conditions Luvox Treats

Luvox is effective for treating an array of conditions related to depression and anxiety. It’s only FDA-approved to treat obsessive-compulsive disorder (OCD) but has several off-label uses, including depression.

Off-Label Uses for Luvox

Because it’s effective in treating OCD, Luvox is often prescribed off-label for other anxiety-related mental health conditions, including: 

• General anxiety 
• Panic disorder
• Social phobias
• Eating disorders
• Borderline personality disorder (BPD)

Luvox Can Treat Symptoms of OCD and Depression

Though depression and OCD may sometimes be exacerbated by stressful environments or events, SSRIs like Luvox can help alleviate symptoms of these disorders by regulating serotonin production. 

Symptoms of OCD include: 

• Intense, unreasonable fear
• Racing and intrusive thoughts
• Difficulty tolerating uncertainty
• Requiring order and symmetry to feel safe

Symptoms of depression include: 

• Extreme fatigue
• Apathy or listlessness
• Loss of appetite
• Insomnia
• Lack of interest

Luvox Costs

Pricing for brand name Luvox varies from $32 to over $400 for a month’s supply. The generic version, fluvoxamine, costs between $25 and $30 for the same amount. 

Luvox Side Effects

Luvox has more known side effects than Viibryd. However, many are mild and dissipate after a few weeks. Some of the most common side effects include: 

• Feeling dizzy, weak, sleepy, or tired
• Constipation, stomach pain, nausea, vomiting, diarrhea, or reduced appetite
• Dry mouth or change in taste
• Insomnia
• Headache or shakiness
• Excess gassiness
• Feeling nervous and easily startled
• Excessive sweating
• Common cold symptoms

The following symptoms may indicate an allergic reaction to Luvox or other serious health complications: 

• Allergic reaction, including hives; swelling of the face, mouth, and throat; difficulty breathing
• Signs of low sodium, including headache, brain fog, weakness, seizures, or trouble balancing
• Coughing up or vomiting blood; blood in the urine or stool; unusual vaginal bleeding; bleeding that cannot be easily stopped
• Abnormal weight gain or loss
• Difficulty passing urine
• Sexual problems, such as difficulty orgasming or lowered sex drive
  • Erection lasting more than 4 hours
• Unusual menstrual flow

Like Viibryd, Luvox may also cause serotonin syndrome. If you experience the symptoms of this syndrome listed above, seek medical attention immediately. 

Luvox Warnings

Luvox and other SSRIs may cause adverse reactions in those with the following conditions: 

• Bipolar disorder
• Bleeding problems
• Depression
• Glaucoma
• Heart attack or heart disease
• Heart rhythm problems
• Hyponatremia (low sodium in the blood)
• Mania (feeling elated)
• Seizures
• Liver disease
• Habitual tobacco use

Luvox Drug Interactions

Adverse drug interactions can cause serious health complications. If you take any of the following medications, you should consider alternatives to Luvox: 

• Monoamine oxidase inhibitors (MAOIs)
• Tourette’s syndrome medications, like pimozide
• Warfarin and other blood thinners
• Ibuprofen and other NSAIDs
• St. John’s Wort
