Imitrex vs Treximet
Introduction
For patients experiencing debilitating migraines, certain medications can help to alleviate the intense pain and other associated symptoms. Imitrex and Treximet are two such drugs that have been found effective against migraines. They both work on a particular type of chemical compound in the brain known as serotonin (5-HT), which is involved in triggering migraine attacks. Imitrex, also known as Sumatriptan, works by stimulating serotonin receptors in the brain to narrow blood vessels around the brain, thus reducing headache pain. On the other hand, Treximet is a combination medication consisting of Sumatriptan and Naproxen - an NSAID drug designed to reduce inflammation and provide longer-lasting relief than Imitrex alone. Both drugs offer significant migraine relief but their usage should be based on individual medical history and tolerance for potential side effects.
What is Imitrex?
Sumatriptan (the generic name for Imitrex) was one of the first drugs in the class of triptans, which marked a significant step forward from previous treatment options for migraines. Sumatriptan was initially approved by the FDA in 1991. It works by stimulating serotonin (5-HT) receptors in the brain, which causes narrowing of blood vessels around the brain and consequently reduces pain signals. It is prescribed predominantly for treating acute migraine attacks or cluster headaches.
Treximet, on the other hand, contains two active ingredients: sumatriptan and naproxen sodium - an NSAID that helps relieve inflammation and pain symptoms. This dual-action medication offers both immediate relief with sumatriptan and longer-lasting effects due to naproxen’s anti-inflammatory properties. While both these medications affect serotonin levels to alleviate headache symptoms, Treximet's inclusion of naproxen may result in it having more side effects than Imitrex alone; particularly gastrointestinal issues associated with NSAIDs use.
What conditions is Imitrex approved to treat?
Imitrex and Treximet are both approved for the treatment of specific types of headaches:
- Imitrex is used for the acute treatment of migraines with or without aura in adults.
- Treximet, on the other hand, combines sumatriptan (the active ingredient in Imitrex) with naproxen. It's also meant to treat acute migraine attacks with or without aura, but unlike Imitrex alone, it may be more effective due to its dual-action approach.
How does Imitrex help with these illnesses?
Imitrex helps manage migraines by constricting the blood vessels in the brain, thus relieving migraine symptoms. It does this by binding to serotonin (5-HT) receptors located on nerve endings in the brain and on smooth muscle surrounding cranial blood vessels. When Imitrex binds to these receptors, it causes vasoconstriction or narrowing of these blood vessels. Migraine headaches are thought to result from dilation of these vessels triggered by activation of trigeminal nerves.
Treximet also works in a similar way since it contains sumatriptan, which is essentially what Imitrex is. However, Treximet has an added component - naproxen sodium, which is a non-steroidal anti-inflammatory drug (NSAID). This dual-action combines with both vasoconstrictive and anti-inflammatory properties that can be more effective for some patients experiencing acute migraine attacks.
Therefore, while both medicines help alleviate migraine symptoms through vasoconstriction mechanism via acting upon serotonin levels; Treximet might offer additional benefit due to its NSAID component that can further reduce inflammation associated with migraines.
What is Treximet?
Treximet is a combination of sumatriptan and naproxen sodium, designed to treat the symptoms of migraine. Sumatriptan (also found in Imitrex) works as a serotonin receptor agonist, inducing vasoconstriction of the cranial blood vessels - this means it reduces their diameter which can relieve headache. It also blocks the release of inflammatory substances that can cause other symptoms associated with migraines. Naproxen sodium is an NSAID (non-steroidal anti-inflammatory drug), contributing additional pain relief by reducing inflammation.
The FDA first approved Treximet in 2008, and while it contains one of the same active ingredients as Imitrex, its unique blend offers potential advantages for patients who have not responded well enough to triptans alone like Imitrex. The dual-action formula may provide quicker or more comprehensive relief from migraine attacks for some sufferers. The side effects are similar to those seen with other NSAIDs and triptans including dizziness, somnolence, tingling sensation or numbness.
What conditions is Treximet approved to treat?
Treximet has been approved by the FDA and is widely utilized to treat acute migraine attacks with or without aura in adults. It serves as an effective solution for:
- Acute migraines, known for its rapid relief from debilitating symptoms.
- Migraine-related nausea and sensitivity to light or sound.
Remember that Treximet should not be used as a prophylactic therapy or taken daily; it's specifically formulated to manage active migraine episodes.
How does Treximet help with these illnesses?
Treximet is a medication used for the treatment of migraine headaches and contains two active ingredients - sumatriptan (which is also the active ingredient in Imitrex) and naproxen. Sumatriptan works by stimulating serotonin receptors in the brain, which causes the muscles surrounding blood vessels in the brain to contract and thus reduces headache pain. The naproxen component further helps by reducing inflammation that can lead to headache pain as well as other body discomforts associated with migraines such as sensitivity to light or sound. Thus, Treximet not only addresses acute migraine symptoms but also has an added anti-inflammatory aspect due to naproxen’s presence. This combination may make it more effective than Imitrex alone for some patients.
How effective are both Imitrex and Treximet?
Both sumatriptan (Imitrex) and Treximet have demonstrated effectiveness in treating acute migraine attacks, with an approval history from the FDA that is only one year apart. However, they are prescribed under different circumstances due to their unique components. Sumatriptan alone acts as a selective serotonin receptor agonist that narrows blood vessels around the brain and reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms. On the other hand, Treximet contains not only sumatriptan but also naproxen; a nonsteroidal anti-inflammatory drug (NSAID) effective for reducing inflammation.
The efficacy of both drugs was studied in numerous clinical trials which showed comparable effectiveness in alleviating severe migraine symptoms within two hours after administration. Notably though, it was found that patients who were administered Treximet reported fewer recurrent migraines within 24 hours compared to those who took Imitrex alone.
A review of meta-analysis reports on Imitrex revealed its substantial influence on relieving migraines at first onset but noted possible side effects such as chest or throat tightness - albeit mild and transient. It has become globally recognized among triptans worldwide for its reliable effect on managing acute migraines.
Treximet's combined action of targeting inflammation while constricting dilated blood vessels seemingly offers additional benefits over using sumatriptan alone when it comes to preventing rebound headaches – a common issue among many migraine sufferers following initial relief from medication use.
In conclusion: Both medications offer considerable relief for those suffering from debilitating migraines; however each has unique attributes potentially beneficial depending upon individual patient needs or specific circumstances surrounding their condition.
At what dose is Imitrex typically prescribed?
Oral dosages of Imitrex range from 25-100 mg per dose, but studies have shown that a 50 mg dose is sufficient for treating migraines in most people. Adolescents aged 12-17 years may be started on a lower dosage, typically around 25 mg. In either population, the dosage can be increased after two hours if there is no relief from symptoms. However, it's crucial not to exceed the maximum daily dose of 200mg.
Treximet contains sumatriptan (the active ingredient in Imitrex) and naproxen. Each Treximet tablet contains 85 mg of sumatriptan and 500 mg of naproxen sodium (a nonsteroidal anti-inflammatory drug). The recommended dose for adults is one tablet as soon as symptoms appear. If your headache comes back after your first dose you can take another tablet anytime after at least two hours have passed since the initial treatment. However, do not consume more than two tablets within any single day.
Please remember to always follow your doctor's advice when taking these medications.

At what dose is Treximet typically prescribed?
Treximet treatment is typically initiated at a dosage of one tablet, which contains 85 mg of sumatriptan and 500 mg of naproxen. The dose can then be increased to two tablets in a day if the response is inadequate after two hours from the initial dose. However, these doses should be spaced sufficiently apart with an interval not less than two hours. The maximum daily dosage is two tablets in any 24-hour period. This may be tested if there's no response to treatment at an initial single-tablet dose after several attempts on separate occasions.
What are the most common side effects for Imitrex?
Common side effects of Imitrex (sumatriptan) include:
- Sensations of tingling/prickling/heat
- Pressure or heaviness sensation in any part of the body
- Weakness, fatigue, drowsiness
- Dizziness, vertigo
- Hot flushes
- Discomfort or stiffness in the neck, throat, jaw or chest
- Feeling sick (nausea) or being sick (vomiting), although this may be due to migraine itself
Whereas Treximet has a similar list but a few more possible side effects including:
- Dry mouth and thirst
- Sweating
- Flushing
Are there any potential serious side effects for Imitrex?
In rare circumstances, Imitrex can have serious side effects. These include:
- Unusual changes in mood or behavior, such as agitation and hallucinations
- Signs of severe allergic reactions like development of hives, difficulty breathing, swelling around the face or throat region.
- Visual disturbances including blurred vision, impaired peripheral vision and eye pain
- Cardiac symptoms such as rapid heart rate palpitations or feelings of tightness in chest that may spread to neck jaw and arms resulting in shortness of breath
- Hyponatremia which is characterized by headaches confusion slurred speech vomiting muscle weakness cramps seizures unsteadiness etc
- A condition called Serotonin Syndrome with symptoms ranging from agitation hallucinations fever overactive reflexes nausea vomiting diarrhea loss of coordination
On the other hand Treximet contains two active ingredients (Sumatriptan & Naproxen) which work together to relieve migraine headache but it has its own share of potential side effects. It's important for individuals considering these medications to discuss their medical history and possible side effect profiles with their healthcare provider before starting treatment.
What are the most common side effects for Treximet?
Treximet, a combination medication used for treating migraines, can cause several side effects including:
- Nausea or vomiting
- Dry mouth
- Feeling of pressure or heaviness in any part of the body
- Dizziness or feeling faint
- Unusual taste in your mouth after taking the medication
- Sweating
- Tiredness and sleep problems (insomnia)
- Flushing (warmth, redness, or tingling under your skin) While these side effects may seem concerning, it's important to note that Treximet is often more effective at relieving severe migraine symptoms than its component drugs taken individually. However, as with all medications, you should discuss potential risks and benefits with your healthcare provider before making a decision.
Are there any potential serious side effects for Treximet?
While Treximet is generally well-tolerated, be aware that serious side effects can occur. These may include:
- Allergic reactions: Symptoms such as hives, itching, fever or swollen glands could indicate an allergic response to the drug.
- Breathing troubles: Difficulty breathing or swelling in your face and throat might suggest a more severe reaction.
- Changes in heart rhythm: Fast or irregular heartbeats are also potential side effects of Treximet.
- Mood and behavior changes: Unusual shifts in mood or behavior should not be overlooked. If you're feeling confused or experiencing extreme bouts of happiness and irritability with racing thoughts, it's essential to seek medical attention immediately.
- Vision issues: Blurred vision, tunnel vision, eye pain/swelling and seeing halos around lights are less common but serious symptoms linked with this medication.
If you experience any of these severe symptoms after taking Treximet, stop its use immediately and contact your healthcare provider.
Contraindications for Imitrex and Treximet?
Both Imitrex and Treximet, along with the majority of migraine medications, may cause symptoms to worsen in some individuals. If you notice an increase in frequency or severity of headaches, chest pain or pressure, a fast or irregular heartbeat, severe stomach/abdominal pain or bloody diarrhea after taking these drugs, please seek immediate medical attention.
Neither Imitrex nor Treximet should be taken if you have used monoamine oxidase (MAO) inhibitors such as isocarboxazid (Marplan), tranylcypromine (Parnate), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl) within the past 14 days. Always inform your physician about all the medications you are currently taking; MAOIs will require a period of around 2 weeks to clear from your system to prevent dangerous interactions with Imitrex and Treximet.
How much do Imitrex and Treximet cost?
For the brand name versions of these drugs:
- The price for a package of 9 tablets of Imitrex (100 mg) averages around $180, which works out to approximately $20/day.
- The cost for 9 tablets of Treximet (85/500 mg) is about $730, working out to roughly $81/day.
Thus, if you are taking one dose per day as needed for migraine attacks, then brand-name Imitrex is less expensive on a per-day treatment basis. Please note that cost should not be the primary consideration in determining which drug is right for you; effectiveness and suitability based on your individual health profile are paramount.
In terms of generic options:
- Sumatriptan (generic version of Imitrex) costs vary widely depending upon insurance coverage but typically range from as low as about $1.50 up to around $10 per tablet.
- There's currently no generic equivalent available for Treximet in the U.S., so patients requiring this medication will need to opt for the more expensive brand-name drug or discuss alternative medications with their healthcare provider.
Popularity of Imitrex and Treximet
Sumatriptan, available under the brand name Imitrex among others, was estimated to have been prescribed to roughly 3.5 million people in the US in 2020. This medication accounted for approximately 22% of all triptan prescriptions for migraine treatment within that year, and its use has been generally consistent over recent years.
On the other hand, Treximet (a combination of sumatriptan and naproxen sodium) saw a lower prescription rate at an estimated 900 thousand people in the US during the same period. Despite this being significantly less than Imitrex's figures, it holds a distinct advantage as it combines two active ingredients with different mechanisms of action targeting various aspects of migraines. The prevalence of Treximet prescriptions has also remained relatively stable over recent years.
Conclusion
Both Imitrex (sumatriptan) and Treximet (a combination of sumatriptan and naproxen sodium) are widely used in the treatment of migraines, with numerous clinical studies validating their efficacy over placebo treatments. The two drugs may be used concurrently under close medical supervision, as they can interact with each other. Imitrex primarily acts by stimulating serotonin receptors in the brain to decrease swelling of blood vessels around the brain that's associated with migraine headaches.
Treximet combines this action with naproxen sodium, an NSAID that helps reduce inflammation and pain signals at a different level. This dual mechanism means Treximet can often offer more comprehensive relief for some patients, particularly those who don’t respond adequately to triptans alone or experience residual symptoms.
Both medications are available in generic form which is more cost-effective for patients paying out-of-pocket expenses. It's important to note that both Imitrex and Treximet have an onset period before full effect occurs.
The side effect profiles of these two drugs are similar overall but differ due to the added component in Treximet – it carries additional risks related to NSAIDs such as stomach bleeding or kidney issues on top of common side effects like dizziness or tingling sensations seen with sumatriptan. For both medications, patients should monitor their symptoms closely when starting treatment and seek immediate medical attention if conditions worsen significantly.
