Luvox vs. Zoloft

Introduction

Zoloft (sertraline) and Luvox (fluvoxamine) are SSRIs. SSRI is the abbreviation for selective serotonin reuptake inhibitors. Both Zoloft and Luvox are medications for treating obsessive-compulsive disorders or depression.

SSRIs are popular and preferred choice of antidepressants used for treating numerous mental health disorders. They work by inhibiting or blocking reuptake (the nerve cells that reabsorb serotonin that carry signals to the brain). Serotonin has a positive impact on emotions, sleep, and mood. Hence, when SSRIs block reuptake, it ensures the body has more serotonin to pass messages between the nerve cells nearby.

About Luvox and Zoloft

What is Luvox?

It is a form of selective serotonin reuptake inhibitor or an antidepressant. Luvox works by boosting serotonin levels in the brain. It is widely used for treating obsessive-compulsive disorders.

What conditions is Luvox approved to treat?

Since 1983, Luvox has been used to alleviate OCD symptoms in patients worldwide. However, Luvox got its first FDA approval in 2000 for treating obsessive-compulsive disorders (depression). Other mental health conditions that Luvox may be suitable for are anxiety disorders, post-traumatic stress disorder, and social phobia.

How does Luvox work for Obsessive-Compulsive Disorder?

Luvox works by decreasing unwanted thoughts and lowering symptoms of depression which are often part of OCD. Luvox minimizes obsessions that simply don’t go away. It further reduces the urge to carry out repeated tasks like counting, hand-washing, and checking that may otherwise interfere with your daily life. Luvox lowers obsessions while restoring the serotonin balance in the brain.

What is Zoloft?

Zoloft is a popular sertraline brand name. It is a widely used and prescribed medication for treating mental health conditions in children and adults. Sertraline is a selective serotonin reuptake inhibitor or an antidepressant medication. It works similarly to other selective serotonin reuptake inhibitors like Fluoxetine and Citalopram. However, it can take a few weeks before you may start seeing the positive effects of the medication in overcoming symptoms of the mental health condition you may be dealing with.

What conditions is Zoloft approved to treat?

FDA approved Zoloft in 1992 to treat multiple mental health conditions:

• Social anxiety disorder
• Depression
• Panic disorder
• Post-traumatic stress disorder
• Obsessive-compulsive disorder

How does Zoloft work for Obsessive-Compulsive Disorder?

Those people who suffer from obsessive-compulsive disorder can benefit greatly from Zoloft. This medication has a calming effect on the mind and thought process. It is highly effective for minimizing the uncontrollable urges related to performing repetitive tasks in OCD. Zoloft limits the serotonin reuptake into neurons, further improving mood and lowering anxiety, compulsions, fears, and obsessions. However, for best results, researchers suggest using Zoloft in combination with psychotherapies like exposure & response prevention therapy.

Besides OCD, Zoloft also works on bulimia nervosa, premature ejaculation, body dysmorphic disorder, binge eating, and premenstrual dysphoric disorder.

Effectiveness

How effective are Luvox and Zoloft for treating obsessive-compulsive disorder?

Luvox and Zoloft are equally effective. It can be backed by a study on patients with OCD published in PubMed. In this 12-week randomized clinical trial, OCD patients were given doses of Sertraline and Fluvoxamine to determine their efficacy and improvement signs. The two drugs were simultaneously compared to treat OCD patients. They were randomly assigned after assessing their illness severity with YBOCS (Yale-Brown Obsessive Compulsive Scale). The study showed that 60 percent of the patients showed a positive and early response in the fourth week with 95mg sertraline dose and 102 mg/d fluvoxamine.

Dosage Information

How is Luvox administered for Obsessive-Compulsive Disorder?

Luvox or fluvoxamine is readily available in two forms. These are:

• Immediate release tablets

As prescribed by your doctor, you can take both types of Fluvoxamine orally, with or without food. Furthermore, the extended release capsules may not be suitable for children who have not taken Luvox before. Therefore, they may be advised to use a low dose of immediate-release Luvox. However, adults can take either tablets or capsules of Luvox to alleviate and manage OCD.

The dosage administered for the condition will vary and may be raised overtime depending on the symptoms in order to adequately control it.

Contraindications and Interactions

Warnings and general precautions for Luvox and Zoloft

Luvox and Zoloft are drugs that should be used as prescribed by your healthcare provider. It is because they can lead to serious complications when they interact with other medications. For example, Zoloft can increase the risk of bruising and bleeding by using anti-platelets such as clopidogrel, anti-coagulants, and aspirin. Similarly, if you are already at risk of bipolar disorder, then avoid antidepressants like Zoloft. It is because Zoloft can easily trigger a bipolar manic episode.

Likewise, Luvox can also have a high tendency to interact with other drugs and cause major side effects. Some of them include the following:

Alosetron or Lotronex- a medication prescribed for treating diarrhea and IBS. However, when taken with Luvox, Lotronex may not be easily broken down by the body. Hence, you may have a high amount of Lotronex inside your body, which can lead to overdose symptoms and serious medical conditions like seizures and breathing difficulties.

MAOIs or Monoamine oxidase inhibitors: Combined with Luvox, it can increase the risk of serotonin syndrome, which can be life-threatening.

Pimozide is used for speech and muscle tics due to Tourette’s syndrome. However, when taken with Luvox, it can lower the impact of the medication. Luvox slows the body’s ability to eliminate pimozide, leading to abnormal heart rhythm, lightheadedness, blurred vision, and weakness.

Thioridazine is prescribed for schizophrenia. However, with Luvox, the body can retain thioridazine in large amounts, increasing the risk of a fast or abnormal heartbeat.

Tizanidine is used for muscle relaxation. However, Luvox can slow down the body’s ability to break down Tizanidin, which can increase the drug amount in the body leading to lowered blood pressure.

Conclusion

Takeaway

Luvox and Zoloft are both effective treatments for conditions such as obsessive-compulsive disorder. They are both selective serotonin reuptake inhibitors that work by boosting the serotonin levels in the brain, much needed to reduce unwanted thoughts and minimize OCD symptoms. Though Zoloft is an excellent choice for most depressive psychiatric mental health conditions, Luvox has proven to be a better option if you’re dealing with obsessive-compulsive disorder alone.

However, if you’re pregnant or breastfeeding, Zoloft may be a safer choice compared to Luvox. Surprisingly Zoloft is one of the safer serotonin reuptake inhibitors to take during pregnancy if you’re also dealing with mental health conditions like depression and OCD. Please note it is always advisable to use these drugs after consulting with your doctor or general health physician. Discuss your condition with your healthcare provider and the medication you may use already. It is vital to provide a complete medical history and current medication usage because SSRIs can cause serious side effects when they interact with other drugs like MAOIs such as Marplan, Zyvox, Thioridazine, Toloxatone, and Tizanidine, to name a few.
