Prozac vs Ativan
Introduction
For patients with major depressive disorder (MDD) or anxiety-related disorders, certain medications that interact with neurotransmitters can help in managing symptoms and stabilizing mood fluctuations. Prozac and Ativan are two such drugs often prescribed for these conditions. Though they each influence different neurotransmitters, both have an effect on mood balance. Prozac is a selective serotonin reuptake inhibitor (SSRI), primarily affecting the levels of serotonin—a neurotransmitter linked to mood regulation—in the brain. On the other hand, Ativan falls under the category of benzodiazepines and works by enhancing the effects of GABA, a calming neurotransmitter. It's important to note though that while Prozac is mainly used for depression treatment due to its more long-term effects on serotonin levels, Ativan is often used as a short-term relief for acute symptoms of anxiety because of its immediate relaxing effect.

What is Prozac?
Lorazepam (the generic name for Ativan) is a drug in the class known as benzodiazepines, which are commonly prescribed to manage anxiety disorders. Lorazepam was first approved by the FDA in 1977. Ativan works by enhancing the effects of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, effectively decreasing activity in the brain and inducing relaxation. It is often prescribed for short-term treatment of acute symptoms, where immediate relief is required. Unlike Prozac, Lorazepam has a considerable impact on GABA receptors but does not significantly affect serotonin or norepinephrine levels within the CNS. This results in different side effect profiles between these two drugs; while both can cause drowsiness and lethargy, lorazepam may also lead to physical dependence due to its direct interaction with GABA receptor sites.
What conditions is Prozac approved to treat?
Ativan is approved for the treatment of several conditions, including:
- Anxiety disorders, a condition characterized by excessive worry or fear that interferes with daily activities
- Acute symptoms of anxiety, which can occur in response to a specific issue or stressor
- Preoperative sedation, anxiolysis and amnesia, where it's used before surgical procedures to reduce anxiety and memory of the procedure
How does Prozac help with these illnesses?
Ativan, on the other hand, is primarily used to manage anxiety disorders by enhancing the effect of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter that inhibits or reduces activity within the nervous system and effectively slows down brain activity. This calming effect can help with symptoms of anxiety and panic disorder, providing short-term relief for acute symptoms. Ativan works by binding to specific receptors that enhance GABA’s effects leading to decreased anxiety levels, relaxation of muscles, and sedation if required during intensive care procedures. While Prozac focuses more on maintaining serotonin levels over time for depression management, Ativan provides immediate but temporary relief from severe anxiety and panic attacks.
What is Ativan?
Ativan is the brand name for lorazepam, a benzodiazepine medication used primarily to treat anxiety disorders by enhancing the effects of certain natural chemicals in the body. Ativan differs from Prozac as it acts on GABA (gamma-aminobutyric acid), a neurotransmitter that inhibits activity in the brain and has anxiolytic, amnesic, sedative and anticonvulsant properties. First approved by the FDA in 1977, Ativan provides quick relief for acute symptoms of anxiety however unlike SSRIs like Prozac, it carries risks of dependency with long-term use due to its rapid onset. The side-effect profile is also different; common side-effects include drowsiness and fatigue but unlike many SSRIs such as Prozac, weight gain or sexual dysfunction are less commonly reported. Therefore, Ativan may be preferred when immediate short-term relief from acute anxiety symptoms is desired over longer term mood regulation provided by typical SSRI antidepressants such as Prozac.
What conditions is Ativan approved to treat?
Ativan, which is a brand name for lorazepam, has been officially approved by the FDA in the United States to treat:
- Anxiety disorders: This includes generalized anxiety disorder (GAD), as well as panic disorder.
- Preoperative sedation: Ativan can be used to calm and sedate patients before surgery.
- Insomnia due to stress or anxiety: Although it's not its primary use, some doctors may prescribe Ativan for short-term relief of severe insomnia.
How does Ativan help with these illnesses?
Ativan, generically known as lorazepam, is a medication that belongs to the benzodiazepine class and primarily works by enhancing the effects of GABA, an inhibitory neurotransmitter in the brain. Through this mechanism, Ativan has powerful anxiolytic (anxiety-reducing), sedative, hypnotic (sleep-inducing), amnesic (memory loss inducing), anticonvulsant (prevents seizures) and muscle relaxant properties. This makes it highly effective in managing acute anxiety episodes or panic attacks. Unlike Prozac which is a selective serotonin reuptake inhibitor (SSRI) antidepressant aimed at long term management of depression and generalized anxiety disorder by increasing levels of serotonin over time in the brain, Ativan provides immediate relief for severe distressing symptoms but does not treat the underlying cause. Therefore it's often used on 'as needed' basis rather than daily and may be combined with SSRIs like Prozac if both conditions exist concurrently.
How effective are both Prozac and Ativan?
Both fluoxetine (Prozac) and lorazepam (Ativan) have established histories of success in treating patients with mental health disorders, albeit they are used for different indications. Fluoxetine is primarily utilized for depression and anxiety, while lorazepam is used to manage anxiety disorders or provide short-term relief from severe symptoms of anxiety. These drugs were initially approved by the FDA about a decade apart.
In clinical studies comparing the two medications directly, it has been observed that both can effectively reduce symptoms of panic disorder.[1] However, there are important differences to consider when choosing between these treatments. Lorazepam acts quickly - often within 30 minutes - which makes it more appropriate for acute symptom management or as a rescue medication during panic attacks. It also tends to be better tolerated in terms of side effects than fluoxetine.
Fluoxetine is generally considered a first-line treatment option for chronic conditions such as depression and generalized anxiety disorder[2]. It works over time to help rebalance certain chemicals in the brain associated with mood regulation but may take several weeks before its full benefits become apparent. Some people experience side effects like sexual dysfunction or weight changes on this drug.
A review conducted in 2004 showed that fluoxetine's effectiveness begins within the first week of treatment[3], while its safety profile was found favorable compared with many other antidepressants[4]. The same study reported that Prozac had become one of the most prescribed antidepressant drugs worldwide due to this efficacy-safety balance and because it was one among the early SSRI-class antidepressants developed.
Alternatively, Ativan serves as an effective tool against acute bouts of severe stress and anxiousness owing to its fast-acting nature but should not be used long term due to potential risks including dependency.

At what dose is Prozac typically prescribed?
Oral dosages of Ativan range from 0.5–10 mg/day, but typically, single daily doses of 2 to 6 mg are recommended for treating anxiety in most people. For children and adolescents under the age of 18, prescription and dosage should be determined by a healthcare professional. Like Prozac, the dosage can be increased after several weeks if there is no response. However, due to its potential for dependence and withdrawal symptoms, it's essential that increases in dose and duration of treatment with Ativan not be exceeded without consultation with a healthcare provider. The maximum dosage varies significantly depending on individual health factors but should never exceed what has been specifically prescribed by your doctor.
At what dose is Ativan typically prescribed?
Ativan treatment typically begins with a dosage of 0.25 to 0.5 mg, administered three times daily for anxiety and once at bedtime for insomnia. The dose can then be increased up to a maximum of 10 mg/day divided into several doses throughout the day, depending on the patient's response and tolerance level. If there is no significant improvement or if symptoms persist after a few weeks, it may indicate that adjustments are required either in the dosage or medication strategy itself. However, due to Ativan's potential for addiction and withdrawal symptoms upon discontinuation, all changes should be closely supervised by your healthcare provider.
What are the most common side effects for Prozac?
Common side effects of Ativan can include:
- Drowsiness, fatigue
- Dizziness and unsteadiness
- Weakness
- Amnesia or forgetfulness
- Change in appetite
- Constipation, diarrhea
- Nausea, vomiting
- Skin rash
- Weight changes (gain or loss)
- Sleep disturbances (insomnia or excessive sleepiness)
- Decreased sex drive, impotence, abnormal orgasm.
Note that while these are common side effects of the drug Ativan, everyone's body reacts differently to medications. If you experience any severe reactions to this medication such as difficulty breathing; swelling of your face, lips, tongue or throat seek immediate medical attention.
Are there any potential serious side effects for Prozac?
While both Prozac and Ativan are used for treating depression and anxiety, they do have different potential side effects:
- Increased thoughts about suicide or self-harm: While this is a common concern with many antidepressants like Prozac, it's also a possibility when using Ativan. If you notice any increase in suicidal thoughts while taking either medication, seek medical help immediately.
- Signs of an allergic reaction: Both medications can cause severe allergic reactions, including hives; difficulty breathing; swelling of your face, lips, tongue or throat; fever; sore throat; burning eyes; skin pain or a rash that spreads and causes blistering and peeling. If these occur stop taking the medication immediately and contact a healthcare professional.
- Vision changes: Blurred vision is more commonly associated with Ativan than Prozac. Also be aware of tunnel vision, eye pain or swelling and seeing halos around lights.
- Heart problems: Fast heartbeats are more often linked to Ativan use but could potentially happen on either drug. Fluttering in your chest may indicate serious heart conditions requiring immediate medical attention.
- Low sodium levels in the body could lead to headache confusion slurred speech severe weakness vomiting loss of coordination feeling unsteady Severe nervous system reaction - Very rigid muscles high fever sweating confusion fast uneven heartbeats tremors feeling faint are all potential serious side effects from both drugs but particularly so for ativan Any symptoms of serotonin syndrome which includes agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea should warrant immediate emergency care
What are the most common side effects for Ativan?
Ativan, a commonly prescribed medication for anxiety and panic disorders, has its own set of potential side effects that patients should be aware of. These may include:
- Drowsiness or fatigue
- Muscle weakness or lack of balance
- Dizziness or lightheadedness
- Dry mouth or salivation changes
- Nausea, vomiting, constipation
- Changes in appetite leading to weight changes
- Blurred vision
- Sleep disturbances like insomnia
Confusion, forgetfulness, depression
Unusual mood swings including aggression, agitation
Rash or other skin reactions are rare but possible. Frequent urination is not typically associated with Ativan use. It's important to note that everyone reacts differently to medications; while some individuals might experience these symptoms when taking Ativan others may not. Always consult your doctor about any concerning side effects you're experiencing during treatment.
Are there any potential serious side effects for Ativan?
While Ativan is generally considered to be a safe and effective medication, it does have the potential for severe side effects in certain individuals. These may include:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Severe drowsiness or lightheadedness
- Unusual changes in mood or behavior including confusion, aggression, hallucination
- Worsening symptoms of depression and suicidal thoughts
- A sudden restless feeling or excitement
- Muscle weakness, drooping eyelids
- Trouble swallowing
- Vision changes If you experience any of these side effects while taking Ativan, seek immediate medical attention. It's essential to remember that this list doesn’t encompass all possible side effects. Always consult with your healthcare provider about possible interactions and complications before starting any new medication.
Contraindications for Prozac and Ativan?
Both Prozac and Ativan, along with most other psychiatric medications, may worsen symptoms of depression in some individuals. If you notice your mental health deteriorating, or an increase in suicidal ideation, thoughts, or behavior while on these drugs, please seek immediate medical attention.
Neither Prozac nor Ativan should be taken if you are taking or have been taking monoamine oxidase (MAO) inhibitors. Always inform your healthcare provider which medications you are currently using; MAOIs will require a period of about 5 weeks to clear from the system to prevent dangerous interactions with both Prozac and Ativan.
Furthermore, because Ativan is a benzodiazepine and can cause physical dependence when used for prolonged periods or at high doses it's important that usage isn't abruptly stopped without consulting a healthcare professional first. This is due to risk of withdrawal effects such as seizures among others.
Lastly it’s important to remember that alcohol should not be consumed whilst being treated with either drug due its potential for enhancing side-effects like drowsiness and impairing concentration even further.
How much do Prozac and Ativan cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Prozac (20 mg) averages around $570, which works out to approximately $19/day.
- The price of a bottle containing 100 tablets of Ativan (1mg) is about $250, working out to roughly $2.50/day if taken as directed.
Thus, if you are on a typical dosage for Ativan (i.e., up to 3 mg/day), then brand-name Ativan is less expensive on a per-day treatment basis than Prozac. However, it's important to note that cost should not be the primary consideration when determining which medication is right for you.
For generic versions - fluoxetine and lorazepam:
- Fluoxetine is available in packs ranging from 15 up to 1000 capsules (20 mg), with costs starting as low as $0.05/day if buying the largest pack upfront and generally not exceeding about $0.90/day.
- Lorazepam can typically be found in bottles containing anywhere from 30 up to 500 tablets (1mg each). If taking one tablet per day, expected daily costs range between approximately $0.08 and $.33 depending on packaging size purchased initially.
Popularity of Prozac and Ativan
Fluoxetine, also known under the brand name Prozac, was prescribed to an estimated 4.7 million people in the USA in 2020. Fluoxetine accounts for just under 20% of SSRI prescriptions and just under 10% of overall antidepressant prescriptions. The prevalence of fluoxetine has been approximately steady over the last decade.
Lorazepam, available as Ativan among other brands, is a benzodiazepine used mainly for treating anxiety disorders. In contrast to Prozac's more stable usage trend over time, Lorazepam had about an estimated prescription count of nearly 14 million back in 2016 according to data from ClinCalc DrugStats Database but has seen a decline since then due its potential risk for dependency with long-term use. Despite this decrease, it still remains one of the most commonly prescribed medications for anxiety in America today.
Conclusion
Both Prozac (fluoxetine) and Ativan (lorazepam) have long-standing records of usage in patients with a variety of mental health conditions, and are backed by numerous clinical studies indicating their effectiveness. In some cases, the drugs may be combined if deemed necessary by a medical professional. However, due to their different mechanisms of action - with Prozac being an SSRI antidepressant that primarily affects serotonin levels, and Ativan being a benzodiazepine that acts on GABA receptors - they tend to be prescribed under different circumstances. Prozac is typically used as a first-line treatment for depression and various anxiety disorders, whereas Ativan is often used for short-term relief of acute symptoms of anxiety.
Both medications can be found in generic form which represents significant cost savings especially for those who must pay out-of-pocket. Both Prozac and Ativan might require an adjustment period; therefore, effects may not be apparent immediately.
The side effect profiles between the two drugs differ somewhat: both are generally well-tolerated but each has its own unique set of potential side effects. With Prozac there's risk of sexual dysfunction and weight changes while Ativan use can lead to drowsiness or physical dependency if used over long periods. For both medications, it’s crucial that patients closely monitor their moods particularly when initiating therapy; immediate medical assistance should be sought if worsening depression or suicidal thoughts arise.
