Midazolam vs Xanax
Introduction
For patients dealing with anxiety disorders, insomnia or seizure disorders, certain drugs that impact the central nervous system can aid in managing symptoms and bringing about relief. Midazolam and Xanax are two such medications often prescribed for these conditions. Both of them belong to a class of drugs known as benzodiazepines which enhance the effect of GABA neurotransmitter resulting in sedative, hypnotic (sleep-inducing), anxiolytic (anti-anxiety), anticonvulsant, and muscle relaxant properties.
Midazolam is often used in medical procedures requiring sedation due to its rapid onset and short duration of action while also being available in injectable forms. On the other hand, Xanax (Alprazolam) is typically used for longer-term treatment of severe generalized anxiety disorder or panic disorder given its longer half-life compared to Midazolam.
What is Midazolam?
Midazolam (the generic name for Versed) is a drug from the benzodiazepine class of sedatives, which was a significant advancement over the first class of sedative drugs known as barbiturates. Midazolam was first approved by the FDA in 1985. It increases levels of free GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter, by enhancing its effect rather than preventing it from being reabsorbed: this keeps it active in the brain for longer than usual. It is prescribed for acute management of seizures and preoperative sedation among other uses. Midazolam has a predominant influence on GABA with only minor influence on serotonin and dopamine, resulting in fewer side effects than other sedatives that have stronger effects on these two other neurotransmitters.
On the contrary, Alprazolam (the generic name for Xanax), also belongs to the benzodiazepines family; however, it's primarily used to treat panic disorder and anxiety disorders. Similar to Midazolam, Alprazolam influences GABA but tends to have more potential side-effects due its more potent impact on serotonin and dopamine.
What conditions is Midazolam approved to treat?
Midazolam is approved for the management of various conditions such as:
- Preoperative sedation
- Anxiolysis (reduction of anxiety)
- Induction of general anesthesia
On the other hand, Xanax is primarily prescribed for:
- Generalized anxiety disorder (GAD)
- Panic disorders
- Anxiety associated with depression
How does Midazolam help with these illnesses?
Midazolam helps to manage anxiety and induce sleep by increasing the efficiency of GABA, a neurotransmitter that inhibits activity in the brain. It does this by binding to the benzodiazepine site on the GABA-A receptor and enhancing its effects, which results in increased inhibitory signals throughout the central nervous system. This leads to sedation, muscle relaxation, decreased anxiety, and even amnesia. Midazolam is often used for procedural sedation due to its rapid onset of action and short duration.
GABA plays an important role in mood regulation, stress response, sleep cycle management among other things. It's believed that individuals with high levels of anxiety may have lower levels or reduced sensitivity to GABA. Therefore, by enhancing GABA's effects through drugs like Midazolam can help patients manage their condition better.
What is Xanax?
Xanax is a brand name for alprazolam, which belongs to the benzodiazepine class of drugs. It works by enhancing the activity of GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter in the brain. This action results in a calming effect and helps to reduce anxiety and panic disorders. Xanax was first approved by the FDA in 1981.
As alprazolam is not an SSRI antidepressant, it does not inhibit serotonin reuptake. Its lack of action on serotonin signifies that its side-effect profile differs from those of SSRIs -- it doesn't typically induce weight gain or sexual dysfunction as seen with many SSRIs like Prozac.
Moreover, unlike some medications such as midazolam, Xanax does not usually cause significant sedation; however, drowsiness can occur especially at high doses or when initially starting treatment. The effects on GABA make it particularly beneficial for individuals suffering from acute symptoms related to anxiety disorders who may not respond well to conventional SSRI drugs.
What conditions is Xanax approved to treat?
Xanax has been authorized by the FDA for treating a variety of conditions such as:
- Anxiety disorders
- Short-term relief of symptoms of anxiety
- Panic disorder, with or without agoraphobia.
How does Xanax help with these illnesses?
Xanax, or alprazolam, is a benzodiazepine that affects gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain. It works by enhancing GABA's effects to calm hyperactive mental processes. Much like midazolam, Xanax is primarily used for its anxiety and panic disorder alleviating properties due to its tranquilizing effect. However, Xanax differs from midazolam in that it has a longer duration of action and can be prescribed for regular use in managing symptoms of anxiety disorders. This makes it more suitable than midazolam, which is typically used for short-term treatment scenarios such as preoperative sedation or acute seizure management rather than chronic conditions due to its shorter half-life.
How effective are both Midazolam and Xanax?
Both Midazolam and Alprazolam (Xanax) are benzodiazepines, used primarily for managing anxiety disorders, panic attacks, or as sedatives before medical procedures. However, they have different onset times and durations of action due to their distinct pharmacokinetic properties. While midazolam has a rapid onset of action making it suitable for acute management such as preoperative sedation or severe agitation episodes, alprazolam has a relatively slower onset but longer duration of effect which is beneficial in disorders like generalized anxiety disorder.
Midazolam and alprazolam were initially approved by the FDA within 7 years apart (1985 & 1992 respectively). A study published in Anesthesia & Analgesia journal in 2004 showed that both midazolam and alprazolam had similar anxiolytic effects although midazolam was found to be slightly more potent than alprazolam.
A review article from the Journal of Clinical Psychopharmacology reported that Xanax begins relieving symptoms within the first week of treatment with few side effects experienced by patients. The same report also states that Xanax's safety profile makes it one of the most prescribed medications worldwide for managing anxiety disorders.
On the other hand, multiple studies indicate that midazolam serves its purpose effectively during pre-operative scenarios providing adequate sedation and amnesia. However due to its fast-acting nature combined with potential adverse effects such as respiratory depression; careful monitoring is required especially when used outside hospital settings.
Altogether both drugs serve unique purposes - while xanax can be an optimal choice for long-term management due to fewer withdrawal symptoms upon discontinuation; midzalom can be preferred when immediate relief is expected without causing prolonged drowsiness.
At what dose is Midazolam typically prescribed?
Oral dosages of Midazolam range from 7.5-15 mg/day, but studies have indicated that a starting dose of 7.5 mg/day is usually sufficient for treating short-term severe insomnia in most people. Elderly patients may be started on lower doses, such as 3.75 mg/day to reduce the risk of adverse effects. In either population, dosage can be increased after a few weeks if there is no response or the symptoms persist, however it's important to note that this medication should only be used for short term treatment (up to two weeks). The maximum dosage that should not be exceeded in any case is 30mg per day.

At what dose is Xanax typically prescribed?
Xanax treatment typically commences at a dosage of 0.25 to 0.5 mg taken three times daily. This dose may be gradually increased every three to four days by no more than 1 mg/day, up to a total dosage of approximately 4 mg/day, divided into smaller doses that should be taken at intervals throughout the day. The maximum dose is largely dependent on the patient's response and tolerance but generally should not exceed 4 mg/day divided into several doses across the day; any increase beyond this point should only be done under close medical supervision due to potential for dependence and withdrawal symptoms upon cessation.
What are the most common side effects for Midazolam?
Common side effects of Midazolam include:
- Drowsiness, somnolence (sleepiness)
- Light-headedness
- Impaired coordination/balance
- Anterograde amnesia (inability to create new memories after the event that caused the amnesia)
- Cognitive dysfunction
- Headache
- Heart rate changes, blood pressure changes
- Nausea and vomiting
- Hiccups or coughing
- Rash or skin inflammation -Dry mouth
On the other hand, Xanax can cause side effects such as:
-Anxiety and nervousness
-Increased salivation or dry mouth
-Decreased libido (sex drive)
-Tremors (unintentional shaking)
-Difficulty with micturition
-Nausea/diarrhea
-Joint pain
It is important to note that these are general lists of possible side effects. Everyone's body responds differently to medication so not everyone will experience all of them. If you have any concerns about these medications' side effects, it would be best to consult your healthcare provider for further advice.
Are there any potential serious side effects for Midazolam?
While Midazolam and Xanax both fall under the category of benzodiazepines, they can have distinctive side effects. Here are some potential adverse reactions related to Midazolam:
- A significant change in mood or behavior, such as increased agitation, hostility, panic attacks or suicidal thoughts
- Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat.
- Vision changes like blurred vision or seeing halos around lights
- Irregular heartbeats that might feel fast, pounding or fluttering in your chest
- Shortness of breath accompanied by a sudden feeling of lightheadedness as if you might faint
- Low sodium levels - symptoms may include headache, confusion and slurred speech along with severe weakness and vomiting leading to loss of coordination and unsteady feelings.
Severe reactions affecting the nervous system could present themselves through very rigid muscles coupled with high fever, excessive sweating causing confusion. This could also be marked by uneven heartbeats leading to tremors and a sensation akin to passing out.
If serotonin syndrome sets in due its interaction with other medications you're taking simultaneously – watch for signs including agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea
The moment any such symptoms manifest after consuming midazolam seek immediate medical intervention.
What are the most common side effects for Xanax?
Xanax, a commonly prescribed benzodiazepine, may produce a range of side effects such as:
- Dry mouth and increased salivation
- Blurred vision and dizziness
- Nausea or constipation
- Changes in weight or appetite
- Difficulty sleeping (insomnia) or unusual dreams
- Shortness of breath, rapid breathing, or feeling lightheaded
- Muscle weakness, lack of balance and coordination
- Memory problems and confusion
- Anxiety or agitation
- Skin rash
Increased urination.
Remember that these side effects are potential risks associated with Xanax use but not everyone who uses the medication will experience them. If any occur persistently though, it is important to seek medical advice immediately.
Are there any potential serious side effects for Xanax?
While Xanax is commonly prescribed and often effective, it can potentially produce serious side effects in some individuals. These may include:
- Signs of an allergic reaction such as hives, difficulty breathing or swallowing, swelling of the face, lips, tongue or throat.
- Unusual risk-taking behavior or thoughts of suicide
- Hallucinations or confusion
- Hostility and hyperactivity
- Uncontrolled muscle movements, tremor, seizure (convulsions)
- Racing heartbeat or fluttering in your chest
- A light-headed feeling like you might pass out
These symptoms indicate a need for immediate medical attention. Hence if you experience any of these adverse reactions while taking Xanax, please contact your healthcare provider immediately.
Contraindications for Midazolam and Xanax?
Both Midazolam and Xanax, as part of the benzodiazepine class of medications, can potentially worsen symptoms of depression in some individuals. If you observe an increase in negative moods or suicidal thoughts while taking these medications, immediately seek medical attention.
Neither Midazolam or Xanax should be taken if you are currently on certain classes of medication, such as azole antifungals (for example ketoconazole), macrolide antibiotics (for instance erythromycin), HIV protease inhibitors (like ritonavir) among others due to potential serious interactions. Always inform your physician about all the drugs you're taking; these particular interacting drugs may need a sufficient period to clear from your system before initiating therapy with either Midazolam or Xanax.
How much do Midazolam and Xanax cost?
For the brand name versions of these drugs:
- The price of 60 tablets (0.5 mg) of Xanax, a well-known brand-name formulation for Alprazolam, averages around $350 which works out to $3–6/day depending on your dosage.
- On the other hand, Versed – a popular brand name version for Midazolam – is typically sold in vials instead of tablets due to its common use as an injectable sedative in medical procedures. A single 10mg/2ml vial costs approximately $20-$30.
Therefore, if you are taking higher doses daily (i.e., more than 1.5 mg/day), then Xanax tends to be more expensive when compared with midazolam.
For the generic versions:
-
Alprazolam (Xanax's active ingredient) runs about $10-$40 for a quantity of thirty 0.5mg tablets which equates roughly from $0.33 - $1.33 per day depending on your dosage and location.
-
For Midazolam syrup (a commonly used format for home use), prices range from about $15-$70 for one 120ml bottle at a concentration of 2mg/ml; this can last varying lengths depending upon usage but could average around $.25-.93 per day based again upon dosing requirements and local pricing conditions.
It should be noted that cost considerations should not outweigh effectiveness and safety parameters when choosing between these medications under professional advice.
Popularity of Midazolam and Xanax
Midazolam, available in brand names such as Versed, was estimated to have been prescribed to about 3.5 million people in the US in 2020. Midazolam accounted for just under 7% of benzodiazepine prescriptions across the country. Predominantly used as a sedative and anesthetic agent during medical procedures, its use has seen a steady increase since it came into prominence.
Alprazolam, including brand versions such as Xanax, on the other hand was prescribed to approximately 25 million people in the USA in 2020. In terms of overall benzodiazepine prescriptions within the US, alprazolam accounts for roughly 50%. Mainly employed for treating anxiety disorders and panic attacks, alprazolam's prevalence has remained relatively consistent over recent years.
Conclusion
Both midazolam and Xanax (alprazolam) have established records of use in patients with anxiety and, as benzodiazepines, they act by enhancing the effect of the neurotransmitter GABA to induce a calming effect. These medications are sometimes used together under careful consideration by a physician due to their potential for additive sedative effects. Midazolam typically has a faster onset but shorter duration of action than Xanax, making it especially useful for procedures requiring quick sedation or as part of anesthesia protocols.
Xanax is often considered as first-line treatment for panic disorders or generalized anxiety disorder whereas midazolam is mainly indicated for pre-procedural sedation or acute seizure management.
Both drugs are available in generic form helping reduce costs particularly for those who self-finance their medication expenses. Both midazolam and Xanax may require an adjustment period; hence immediate effects might not be noticeable right away.
The side effect profiles between both drugs are similar with common side effects including drowsiness and lightheadedness. However, compared to Xanax, midazolam's shorter half-life can result in less prolonged sedation. It's crucial that patients closely monitor their moods when initiating therapy with these medications and seek medical attention immediately should they experience worsening symptoms or develop thoughts about self-harm.
