Anafranil vs Luvox
Introduction
Patients with obsessive-compulsive disorder (OCD) or similar conditions often require medications that adjust the balance of certain brain chemicals, namely neurotransmitters, to help control symptoms and improve their quality of life. Anafranil and Luvox are two such drugs commonly prescribed for these disorders. They both influence different neurotransmitters in the brain but share a common goal: reducing the severity of OCD symptoms. Anafranil is a tricyclic antidepressant (TCA), which primarily affects serotonin levels but also impacts norepinephrine concentrations in the brain. On the other hand, Luvox belongs to selective serotonin reuptake inhibitors (SSRIs), specifically targeting serotonin levels without significantly affecting other neurotransmitters like norepinephrine or dopamine.

What is Anafranil?
Clomipramine (the generic name for Anafranil) was one of the first drugs in a class of antidepressants known as tricyclic antidepressants (TCAs). It was approved by the FDA in 1989. Similar to Prozac, Anafranil works by increasing levels of serotonin in the brain; however, it does this by blocking the absorption or reuptake of both serotonin and norepinephrine. On the other hand, Fluvoxamine (Luvox) is an SSRI like Prozac but it specifically targets obsessive-compulsive disorder (OCD). Luvox has a selective influence on serotonin with only minor effects on norepinephrine and dopamine which results in fewer side effects than those antidepressants that have stronger influences on these two additional neurotransmitters.
What conditions is Anafranil approved to treat?
Anafranil is approved for the treatment of various mental health disorders, including:
- Obsessive-compulsive disorder (OCD), a chronic condition where an individual experiences uncontrollable and recurring obsessions or compulsions
- Panic disorder, characterized by recurrent unexpected panic attacks
- Major depressive disorder (MDD), also known as unipolar depression
- Chronic pain associated with certain conditions.
How does Anafranil help with these illnesses?
Anafranil, like Prozac, helps to manage depression and obsessive-compulsive disorder by increasing the amount of serotonin available in the synapses of the brain. It does this by inhibiting its reuptake into the presynaptic neuron, so levels can be maintained higher for longer periods of time. Serotonin is a neurotransmitter that plays an important role in mood regulation, cognition, memory, sleep patterns and appetite. It's believed that people with depression or OCD may have relatively lower levels of serotonin. Therefore, by increasing serotonin availability through reuptake inhibition achieved with Anafranil use, it can limit the negative effects associated with these disorders and help patients manage their condition better.
On the other hand, Luvox (Fluvoxamine), while still being a selective serotonin reuptake inhibitor (SSRI) like Anafranil (Clomipramine), it also affects other neurotransmitters such as norepinephrine and dopamine to some extent due to its interaction with various receptor sites. This means Luvox might offer additional benefits for patients who do not respond sufficiently to medications that target only one neurotransmitter system.
What is Luvox?
Luvox, also known as fluvoxamine, is a selective serotonin reuptake inhibitor (SSRI) that works by increasing the levels of serotonin in the brain. Similar to how bupropion affects norepinephrine and dopamine, fluvoxamine reduces the reabsorption of serotonin, leading to increased amounts available in the brain. This can help alleviate symptoms of depression and anxiety disorders.
Fluvoxamine was first approved by FDA in 1994 mainly for the treatment of obsessive-compulsive disorder (OCD), unlike Anafranil which is an older tricyclic antidepressant typically used when SSRIs are ineffective. As an SSRI, Luvox has a different side-effect profile compared with tricyclics such as Anafranil; it tends not to cause dry mouth or constipation but instead might lead to sleep disturbances and sexual dysfunction - common issues associated with SSRIs.
The effects on serotonin make Luvox beneficial for treating OCD and other conditions like social anxiety disorder or panic disorder where there's often a need for long-term medication use. It may be particularly helpful for patients who have not responded well to “typical” anti-anxiety drugs.
What conditions is Luvox approved to treat?
Luvox is an FDA-approved medication used for the treatment of:
- Obsessive-compulsive disorder (OCD)
- Social anxiety disorder, also known as social phobia
How does Luvox help with these illnesses?
Serotonin is a neurotransmitter that plays vital roles in various bodily functions, including mood regulation, sleep promotion, appetite control and cognitive processing. Low levels of serotonin have been associated with depression and anxiety disorders. Luvox operates by increasing the availability of this neurotransmitter in the brain to alleviate symptoms related to obsessive-compulsive disorder (OCD). It achieves this by inhibiting its reuptake into presynaptic neurons thereby allowing more serotonin to be available for neuronal signaling. This action on serotonin significantly differs from Anafranil which not only affects serotonin but also impacts norepinephrine levels; another neurotransmitter involved in mood regulation and stress response. Because Luvox specifically targets the serotonergic system without substantially influencing other neurotransmitters, it can sometimes be prescribed when patients do not respond well or experience unwanted side effects with broader spectrum antidepressants such as tricyclics like Anafranil.
How effective are both Anafranil and Luvox?
Both clomipramine (Anafranil) and fluvoxamine (Luvox) have established histories of success in treating patients with obsessive-compulsive disorder (OCD), and they were initially approved by the FDA several years apart. Since they act on different neurotransmitters, they may be prescribed under different circumstances. The effectiveness of clomipramine and fluvoxamine in alleviating OCD symptoms was directly studied in a double-blind clinical trial in 1991; both drugs exhibited similar efficacy in managing symptoms of OCD as well as similar safety profiles. In this study, none of the metrics used to measure efficacy in treating OCD revealed differences between patients receiving clomipramine or those receiving fluvoxamine.
A review conducted on clomipramine studies showed that it is effective from the first week of treatment, has a side effect profile consistent with other tricyclic antidepressants, and is generally well-tolerated even among elderly populations. Clomipramine has become one of the most commonly prescribed medications for severe cases of OCD due to its long history and extensive study supporting its effectiveness against this condition.
A 2016 meta-analysis indicated that fluvoxamine seems more effective than placebo at treating OCD symptoms, similar to other common SSRIs used for this purpose. Although typically considered a second-line treatment option after exposure therapy or cognitive-behavioral therapy have been tried without sufficient improvement, Luvox can also be co-prescribed alongside these therapeutic modalities for maximum benefit.

At what dose is Anafranil typically prescribed?
Oral dosages of Anafranil (Clomipramine) for adults typically start at 25 mg/day and are gradually increased, as needed, to a maximum of 250 mg/day. For children and adolescents aged 10-17 years old with obsessive-compulsive disorder (OCD), the recommended starting dosage is 25 mg daily, increasing gradually up to 3 mg/kg or 100mg/day (whichever is smaller). In both populations, there should be careful monitoring by the prescribing physician during dosage increases since side effects can occur. On the other hand, Luvox (Fluvoxamine) doses for adults generally begin at 50 mg/day and may be increased in increments of up to an additional 50mg per day every week if required; however, it should not exceed a maximum dose of about 300mg daily under any circumstances. For children and adolescents with OCD aged between eight to seventeen years old, initial dosing starts lower at around approximately half that recommended for adults on a weight-adjusted basis.
At what dose is Luvox typically prescribed?
Luvox (fluvoxamine) treatment is typically initiated at a dosage of 50 mg/day, taken in the evening. The dose may then be increased by your doctor, usually every 4-7 days, up to a maximum of 300 mg/day for adults and 200 mg/day for adolescents and elderly patients. This daily total is often divided into two doses - one taken in the morning and one in the evening - although some people may take it as a single dose before bed. If there is no significant response after several weeks on this medication at the maximum recommended dose, your healthcare provider might consider further options or adjustments.
What are the most common side effects for Anafranil?
Anafranil and Luvox are both used to treat obsessive-compulsive disorder (OCD), but they have different side effects. Common side effects of Anafranil include:
- Dry mouth
- Nausea, vomiting, loss of appetite, stomach cramps
- Constipation or diarrhea
- Drowsiness, dizziness
- Trouble sleeping (insomnia)
- Sweating
- Weight changes and increased cholesterol levels
- Decreased libido (sex drive) and other sexual difficulties such as impotence or ejaculation problems.
On the other hand, common side effects of Luvox may include:
- Nervousness or anxiety
- Sleep disturbances including insomnia and vivid dreams
- Somnolence (sleepiness/drowsiness)
- Tremor (unintentional trembling or shaking)
- Upset stomach, gas, decreased appetite
- Diarrhea; constipation
- Dry mouth
It's important to discuss these potential side effects with your healthcare provider before starting treatment. They can help you weigh the benefits against the risks in light of your specific circumstances.
Are there any potential serious side effects for Anafranil?
Like any medication, both Anafranil (clomipramine) and Luvox (fluvoxamine) can have side effects. Here are some that you need to watch out for:
- Thoughts about suicide or self-harm may increase, particularly in the initial stages of treatment or when doses are adjusted.
- There may be signs of an allergic reaction like hives; difficulty breathing; swelling in your face, lips, tongue or throat. In severe cases, there might be a serious skin reaction with symptoms like fever; sore throat; burning eyes; skin pain followed by a red or purple rash that spreads resulting in blistering and peeling.
- Vision disturbances could occur such as blurred vision, tunnel vision, eye pain or swelling and seeing halos around lights.
- Rapid heartbeats that feel pounding coupled with chest fluttering could happen along with shortness of breath and sudden dizziness - giving you a feeling like you might pass out.
- A drop in sodium levels in the body might cause confusion due to headaches, slurred speech paired with severe weakness leading to vomiting then loss of coordination causing unsteadiness.
- Severe nervous system reactions can occur where muscles become very stiff (rigid), accompanied by high fever sweating confusion rapid uneven heartbeats tremors creating a sensation similar to passing out.
Serotonin syndrome is another potential risk which exhibits through increased agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea. If any symptom occurs consult your doctor immediately.
What are the most common side effects for Luvox?
When considering Luvox (fluvoxamine), potential side effects that patients may experience include:
- Upset stomach, nausea, or loss of appetite
- Dry mouth and throat discomfort
- Changes in sleep patterns, including insomnia
- Increased sweating and feelings of nervousness or anxiety
- Headaches or dizziness
- Blurred vision
- Fast heartbeat
- Symptoms akin to the flu such as stuffy nose or sore throat
- Occasional confusion, agitation, or displays of hostility
- Some patients might experience a skin rash
- Unexplained weight loss could occur in some cases
-Increased frequency of urination. -Muscular weakness or joint pain.
As with all medications, it's important for users to monitor their symptoms closely and report any severe reactions immediately to their healthcare provider.
Are there any potential serious side effects for Luvox?
While Luvox is generally considered safe, it can cause serious side effects in some rare cases. These may include:
- A severe allergic reaction characterized by hives, difficulty breathing or swallowing, swelling of your face, lips, tongue or throat
- Worsening depression or suicidal thoughts
- Seizures (convulsions)
- Unusual changes in behavior or mood swings
- Blurred vision and eye pain
- Rapid heartbeats
- Symptoms of serotonin syndrome such as agitation, hallucinations, fever, sweating, shivering, fast heart rate and muscle stiffness If you experience any of these symptoms while taking Luvox please contact your healthcare provider immediately.
Contraindications for Anafranil and Luvox?
Both Anafranil and Luvox, like most other antidepressant medications, could potentially worsen symptoms of depression in certain individuals. If you notice your depressive symptoms intensifying, or if there's an increase in suicidal thoughts or behaviors while on either medication, please seek urgent medical attention.
Neither Anafranil nor Luvox should be taken if you are currently taking or have recently stopped taking monoamine oxidase inhibitors (MAOIs). It is crucial to inform your healthcare provider about any other medications you may be using; MAOIs require a washout period of approximately 2 weeks before starting treatment with another antidepressant like Anafranil or Luvox to prevent dangerous drug interactions.
How much do Anafranil and Luvox cost?
For the brand name versions of these drugs:
- The price of 90 tablets of Anafranil (25 mg) averages around $400, which works out to about $9-$18/day, depending on your dose.
- The price for 60 tablets of Luvox (50 mg) averages around $500, working out to roughly $17/day.
Thus, if you are in the higher dosage range for Anafranil (i.e., 200 mg/day or higher), then brand-name Luvox is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which drug is right for you.
For the generic versions of Anafranil (clomipramine) and Luvox (fluvoxamine), costs are significantly lower:
-
Clomipramine is available in packs ranging from 30 capsules up to larger quantities. A typical cost could range from about $1 to $2 per day for dosages between 100 to 250mg/day.
-
Fluvoxamine can be found in packages starting from as low as packs of ten up through larger quantities. Costs may vary but typically fall within an approximate range between $.70 and $.90 per day at doses between fifty and three hundred milligrams daily.
Popularity of Anafranil and Luvox
Clomipramine, with its brand name Anafranil, was estimated to have been prescribed to nearly 250,000 people in the US in 2020. Clomipramine accounted for less than 1% of antidepressant prescriptions in the US. However, it is one of a few drugs that are specifically indicated for obsessive-compulsive disorder (OCD). The use of clomipramine has been relatively stable over the past decade.
Fluvoxamine, also known by brand names such as Luvox, was prescribed to approximately 500,000 individuals in the USA during the same year. Fluvoxamine represents just under 3% of SSRI prescriptions and slightly over 1% of overall antidepressant prescriptions. Similar to clomipramine, fluvoxamine is often used for OCD treatment but unlike clomipramine its usage has seen a slight increase from previous years due likely due to its potential off-label use related to COVID-19 symptom mitigation.
Conclusion
Both Anafranil (clomipramine) and Luvox (fluvoxamine) have long-standing records of usage in patients with obsessions, compulsions, panic attacks, and depression. They are backed by numerous clinical studies indicating that they are more effective than placebo treatments. In some cases, the drugs may be combined for a stronger effect or to target different symptoms; however, this should be subject to careful consideration by a physician due to potential drug interactions. Their mechanisms of action differ slightly due to Anafranil being a tricyclic antidepressant affecting both serotonin and norepinephrine neurotransmitters while Luvox is an SSRI primarily increasing the level of serotonin.
Anafranil tends to be prescribed as a secondary option when first-line SSRIs like Luvox didn't provide sufficient symptom relief or if there's also presence of chronic pain which can benefit from its dual-action mechanism.
Generic versions for both drugs are available which represents significant cost savings especially for those who must pay out-of-pocket expenses. Both Anafranil and Luvox require an adjustment period where therapeutic effects might not be noticeable immediately.
Regarding side effects profile, although similar between these two medications such as dry mouth or gastrointestinal disturbances; each has unique side-effects - with sexual dysfunction being less likely on Anafranil compared to other SSRIs including Luvox but it may cause more sedation and weight gain instead. For either medication, patients need close monitoring particularly during early stages of treatment; any worsening mood or emergence of suicidal thoughts should prompt immediate medical consultation.
