Vyepti vs Botox
Introduction
For patients suffering from chronic migraines, certain medications can help in managing the frequency and severity of migraine attacks. Vyepti and Botox are two such treatments that are often prescribed for chronic migraines. They work through different mechanisms but both aim to reduce the frequency and intensity of migraines.
Vyepti (Eptinezumab-jjmr) is a monoclonal antibody that works by blocking the activity of calcitonin gene-related peptide (CGRP), a molecule involved in causing migraine pain, thus preventing migraine headaches before they start. It's administered via an IV infusion every three months.
On the other hand, Botox (Botulinum toxin type A) originally used for cosmetic purposes, has found its place in headache management due to its inhibitory effects on muscle contractions and pain signal transmission. In terms of migraines, it is thought to block chemicals called neurotransmitters that carry pain signals from your brain.
Both drugs have been shown to reduce monthly migraine days with their respective modes of action providing relief geared towards individual patient needs and treatment responses.

What is Vyepti?
Vyepti (generic name: eptinezumab-jjmr) is a relatively newer class of medication known as calcitonin gene-related peptide (CGRP) inhibitors, specifically designed for the prevention of migraines. Vyepti was approved by the FDA in 2020 and works by blocking CGRP, which plays a key role in migraine pathophysiology. It's administered intravenously every three months via infusion clinics or at home health services.
On the other hand, Botox (botulinum toxin type A), primarily known for its cosmetic use to reduce wrinkles, has been utilized since 2010 as an effective treatment method for chronic migraines. Administered through injections into specific areas of the head and neck every three months, Botox helps prevent migraines before they start by blocking chemicals called neurotransmitters that carry pain signals from your brain.
Both have shown effectiveness in preventing migraine attacks; however, side effects differ between these two medications. Vyepti might cause allergic reactions and possibly nasal congestion while Botox can result in neck pain or headache immediately after administration.
What conditions is Vyepti approved to treat?
Vyepti has been approved for the treatment of various conditions, including:
- Preventive treatment of migraine in adults
- It can also be used off-label for other types of chronic headaches
Botox, on the other hand, is FDA-approved not only for chronic migraine prevention in adults but also:
- Treatment of overactive bladder and urinary incontinence
- Severe underarm sweating (primary axillary hyperhidrosis)
- Upper limb spasticity
- Cervical dystonia.
Note that both drugs are given by injection but have different modes of administration. Vyepti is administered through intravenous infusion every three months while Botox involves multiple injections around the head and neck area every 12 weeks.
How does Vyepti help with these illnesses?
Vyepti is used to prevent migraines by blocking the calcitonin gene-related peptide (CGRP) receptor, a protein that plays a key role in migraine attacks. Migraines are thought to be caused by an overactive pain signal process in the brain, and CGRP is heavily involved in this process. When a migraine starts, levels of CGRP increase in the body. Vyepti works by binding to the CGRP receptor and thus preventing CGRP from attaching and triggering this cascade of events that lead to a migraine attack.
On the other hand, Botox prevents migraines through a different mechanism: it blocks signals from nerves to muscles, causing them to relax. This muscle relaxation can reduce tension in areas like forehead or neck which may contribute as triggers for some patients' migraines.
Both Vyepti and Botox have been found effective at reducing frequency of migraines but they work differently so might be suited better for different types of patients depending on their unique medical histories.
What is Botox?
Botox, a brand name for botulinum toxin type A, is an acetylcholine release inhibitor and a neuromuscular blocking agent. By preventing the release of this neurotransmitter, Botox inhibits muscle contraction and results in temporary paralysis of the muscles targeted. This can be beneficial in treating conditions that involve excessive muscle activity or spasms such as cervical dystonia (severe neck muscle spasms) and chronic migraines. It was first approved by the FDA in 1989 for therapeutic use and later extended to cosmetic applications including treatment of wrinkles due to its paralytic effects.
Unlike Vyepti which is specifically designed for migraine prevention and given intravenously every three months, Botox requires injections directly into affected muscles every three months for chronic migraines management. The side effect profile differs from drugs like Vyepti because it does not cause common side effects associated with many preventive migraine medications such as fatigue or nausea. Instead, Botox has been known to possibly cause mild pain at injection site or flu-like symptoms.
What conditions is Botox approved to treat?
Botox, apart from its well-known uses in cosmetic treatments, is also approved for the medical treatment of certain conditions such as:
- Chronic migraine
- Severe underarm sweating (primary axillary hyperhidrosis)
- Upper limb spasticity
- Certain eye muscle disorders including strabismus and blepharospasm
- Overactive bladder and urinary incontinence due to neurologic condition.
How does Botox help with these illnesses?
Botulinum toxin, better known as Botox, works by blocking the release of certain neurotransmitters, particularly acetylcholine from the endings of the motor nerves. This prevents the muscles from contracting and hence reduces wrinkles or fine lines. In terms of treating migraines, it is believed that Botox blocks pain signals to the brain in addition to relaxing muscle contractions which can contribute to migraine symptoms. Although Vyepti is an effective treatment for preventing migraines with its mechanism targeting calcitonin gene-related peptide (CGRP), a molecule implicated in migraine attacks; Botox has been used for decades and offers broader uses including cosmetic purposes as well as medical conditions like hyperhidrosis (excessive sweating), overactive bladder and some eye disorders on top of its use in chronic migraine prevention. Therefore, when patients seek a versatile solution or if they have not responded well to other preventatives such as CGRP inhibitors like Vyepti, physicians might opt for using Botox.
How effective are both Vyepti and Botox?
Both eptinezumab (Vyepti) and onabotulinumtoxinA (Botox) have proven to be effective treatments for migraine prevention, although they act through different mechanisms and are administered differently. Vyepti, which was approved by the FDA in 2020, is a CGRP inhibitor given as an intravenous infusion every three months. Botox, initially approved by the FDA in 2010 for chronic migraines, is a neurotoxin that blocks nerve signals causing muscle contraction; it's typically injected into muscles around the head and neck every three months.
In clinical trials comparing these drugs' effectiveness at preventing migraines, both demonstrated similar efficacy in reducing monthly headache days and improving quality of life measures. None of the metrics measured to evaluate treatment efficacy showed significant differences between patients receiving Vyepti or Botox.
A 2021 review of reports on Vyepti suggested that it starts to reduce migraine frequency within the first week of treatment - faster than many oral preventive medications - with minimal side effects reported. This study concluded that Vyepti offers a new option for patients who haven't responded well to other therapies or prefer less frequent administration due to its quarterly dosing schedule.
On the other hand, while Botox has been shown more effective than placebo at reducing migraine frequency according to a 2016 meta-analysis review; some people may not benefit from its use if their headaches aren't mostly located around the forehead area where injections are performed. Furthermore, injection site discomfort can be an issue for certain individuals sensitive to needles. Despite this limitation however, due to its established record and unique mode of action targeting muscle contraction related migraines specifically—Botox remains popular among those requiring preventative therapy especially when other options fail.

At what dose is Vyepti typically prescribed?
Intravenous dosages of Vyepti for migraine prevention usually start at 100 mg once every three months, but clinical trials have indicated that 100 mg is effective for most patients. However, some may benefit from a higher dose of 300 mg if the lower dosage doesn't sufficiently manage their symptoms. On the other hand, Botox injections for chronic migraines are typically administered at intervals of about twelve weeks with multiple injections around the head and neck to dull future headache symptoms. The exact dosage and number of injection sites can vary based on individual patient's needs and response to treatment. In both cases, it is important not to exceed recommended dosages without consulting your healthcare provider.
At what dose is Botox typically prescribed?
Botox for chronic migraines is typically administered at a dosage of 155 Units, divided across 7 specific head/neck muscle areas. The injections are given every 12 weeks. If there's no significant improvement in the patient’s headache frequency after two treatment cycles (24 weeks), you might want to discontinue Botox therapy. However, if it proves effective, your healthcare provider may adjust the dosage and injection sites as necessary during subsequent sessions based on your response and tolerability. It's important to remember that individual responses can vary widely, so what works best will be unique to each person.
What are the most common side effects for Vyepti?
Common side effects of Vyepti may include:
- Nasopharyngitis (common cold)
- Hypersensitivity reactions, including rash and hives
- Mild to moderate nausea
- Tiredness or fatigue
- Dry mouth
On the other hand, Botox might cause:
- Pain at the injection site
- Infection
- Inflammation
- Swelling
- Redness
- Bleeding and bruising.
More serious side effects can occur with both drugs, so it's important to discuss these risks with your healthcare provider before starting treatment.
Are there any potential serious side effects for Vyepti?
When comparing Vyepti and Botox, it's essential to be aware of the potential side effects. For Vyepti, these might include:
- Allergic reactions such as skin rashes or hives, difficulty in breathing or swallowing, swelling of the face, lips or tongue
- Changes in vision
- Irregular heartbeat
- Sudden weight gain caused by fluid retention
- Low mood (depression) or suicidal thoughts
Meanwhile for Botox:
- Difficulty swallowing, speaking or breathing,
- Spread of toxin effects causing muscle weakness all over the body,
- Vision disturbances,
- General ill feeling with feverish symptoms like sweating and confusion.
Both treatments can potentially cause serious nervous system reactions - rigid muscles, high fever, tremors and a feeling as though you may pass out. If any severe side effects are experienced when using either drug - Vyepti or Botox – immediate medical attention should be sought.
What are the most common side effects for Botox?
Botox, another medication often used for treating chronic migraine, can come with a variety of side effects:
- Difficulty swallowing, speaking or breathing
- Loss of strength and muscle weakness all over the body
- Hoarseness or change in voice
- Double vision
- Blurred vision and drooping eyelids
- Loss of bladder control
- Trouble saying words clearly
- Dry mouth
- Tiredness or fatigue. Remember that these symptoms don't occur in everyone who takes Botox; each individual's reaction may vary.
Are there any potential serious side effects for Botox?
Botox, while generally safe for most people, may cause some side effects. These include:
- Signs of an allergic reaction such as hives, difficulty breathing, or swelling in your face, lips, tongue or throat
- Muscle weakness all over the body
- Vision problems including blurred vision and drooping eyelids (may lead to decreased eyesight)
- Trouble with speaking clearly due to muscle weakness
- Difficulty swallowing which can cause severe complications like malnutrition or aspiration pneumonia
- Breathing difficulties that could potentially be life-threatening if muscles controlling breath functions become too weak
- A change in the normal heartbeat rhythm; either too fast or too slow
If you experience any of these symptoms after receiving a Botox treatment it's crucial that you seek immediate medical attention.
Contraindications for Vyepti and Botox?
Both Vyepti and Botox, like many migraine treatments, may have side effects that vary from person to person. If you notice your migraines worsening or the development of new symptoms after receiving these treatments, seek immediate medical attention.
Neither Vyepti nor Botox should be taken if you are allergic to either medication or any of their ingredients. Always inform your doctor about all medications you are currently taking; certain drugs can interact negatively with both Vyepti and Botox.
Botox treatment for chronic migraines requires injections every 12 weeks while Vyepti is administered via intravenous infusion every three months. Both treatments require regular appointments with a healthcare provider to monitor progress and manage potential side effects.
If you're pregnant, plan on becoming pregnant, or breastfeeding, discuss this with your physician as it's not fully known how these medicines affect pregnancy or nursing infants.
How much do Vyepti and Botox cost?
For the brand name versions of these drugs:
- The price of one treatment with Vyepti (100 mg), which is typically administered every 3 months, averages around $1,900. This works out to approximately $21/day.
- The price for Botox varies based on the number of units used and the specific condition it's being used to treat. For chronic migraines, a typical treatment might involve 155 Units costing roughly $1,200 per session. Given that treatments are usually given every 12 weeks or so, this would work out to about $14/day.
Thus if you require regular migraine prevention and your physician recommends either of these treatments as suitable options for you, then Botox may be less expensive on a per-day basis than Vyepti. Please note though that cost should not be a primary consideration in determining which drug is right for you; efficacy and side effects are also very important factors.
Currently there aren't any generic equivalents available for either Vyepti or Botox.
Popularity of Vyepti and Botox
Eptinezumab, marketed under the trade name Vyepti, is an intravenous treatment for migraine prevention approved by the FDA in 2020. As a new entrant to the market and being administered only four times per year, it's still gaining traction among patients and doctors.
On the other hand, OnabotulinumtoxinA (Botox) has been used therapeutically for more than two decades and was approved for chronic migraine treatment in 2010. Botox remains one of the most prescribed medications for this indication with millions of people receiving treatments each year due to its proven efficacy.
While both drugs are designed to prevent migraines before they start, their mechanisms of action differ: Vyepti works by blocking calcitonin gene-related peptide (CGRP), which is believed to play a crucial role in initiating migraines; Botox blocks signals from nerves that trigger muscle contractions, thereby easing muscular tension which might contribute to migraines. Given these differences along with individual factors such as cost, insurance coverage and patient preference may influence whether Vyepti or Botox is chosen.
Conclusion
Both Vyepti (eptinezumab) and Botox (botulinum toxin type A) are used to treat chronic conditions, notably migraines, with a significant amount of clinical research demonstrating their effectiveness. At times, they may be utilized in combination for some patients under the careful supervision of a medical professional; however, this is subject to contraindications and individual patient factors.
Vyepti works by inhibiting calcitonin gene-related peptide (CGRP), which plays a crucial role in migraine pathophysiology. In contrast, Botox works by blocking the release of certain neurotransmitters from nerve endings thus reducing muscle activity.
While Vyepti is usually administered as an intravenous infusion every three months at healthcare facilities, Botox requires injections into specific points on the head and neck muscles every twelve weeks. For those who prefer less frequent treatments or have needle phobia, Vyepti might be more appealing than botox.
Neither drug has generic versions available yet due to patent protections which can make them expensive especially for patients paying out-of-pocket. Both drugs may require time before noticeable effects begin - typically one week for Vyepti and two weeks for Botox.
The side effect profiles of both drugs are generally well-tolerated but differ slightly: common side effects associated with Vyepti include nasal congestion while those associated with botox include neck pain and headache. It's important that patients monitor themselves after treatment and seek immediate medical attention if adverse reactions occur.
