Maxalt (rizatriptan benzoate) is a prescription medication used to treat a migraine headache after it has started. It helps reduce migraine symptoms such as throbbing head pain, nausea, and sensitivity to light or sound. Rizatriptan is a triptan that is believed to work by binding to serotonin receptors in the brain. Maxalt comes as a tablet that is approved for adults and children ages 6 to 17 who have migraines with or without aura.
Take Maxalt at the first sign of a migraine (it is not used to prevent migraines).
Adults usually take 5 mg or 10 mg by mouth, and a second dose may be taken at least 2 hours later if the migraine returns. Do not take more than 30 mg in 24 hours.
If you take propranolol, ask your healthcare provider about the right Maxalt dose.
For children ages 6 to 17, the dose depends on weight:
Children should not take more than one dose in 24 hours.
The active ingredient in Maxalt is rizatriptan benzoate. The inactive ingredients in Maxalt regular tablets may include lactose monohydrate, microcrystalline cellulose, pregelatinized starch, ferric oxide (red), and magnesium stearate.
Before using this medication, you may want to consult a healthcare provider about the following:
Tell your healthcare provider about any risk factors for heart disease, such as high blood pressure, high cholesterol, diabetes, obesity, smoking, a strong family history of heart disease, or being a postmenopausal woman or a man over 40.
Stop using Maxalt and seek medical care for any chest pain, jaw or throat tightness, severe shortness of breath, or sudden weakness on one side of the body. While most chest or throat sensations after taking a triptan are not from heart problems, these symptoms still need to be checked.
Using migraine treatment too often, including triptans like Maxalt, can lead to medication overuse headache, which is a rebound headache caused by excessive use of headache medicines. If you find yourself needing Maxalt or other migraine medicines on 10 or more days per month, talk to a provider about long-term options.
Combining Maxalt with antidepressants such as SSRIs or SNRIs may lead to serotonin syndrome. Symptoms can include restlessness, hallucinations, fast heart rate, fever, sweating, shivering, muscle stiffness or twitching, loss of coordination, nausea, vomiting, or diarrhea.
Use Maxalt with caution if you have liver or kidney problems. Dose adjustments or close monitoring may be needed.
If you take propranolol, the recommended Maxalt dose may be 5 mg, with a maximum of 15 mg in a 24-hour period. Tell your provider about any beta-blockers, MAO inhibitors, or other migraine treatments you’re using.
Avoid taking or using this medication if any of the following apply:
Common side effects of Maxalt include:
Get medical help for any signs of a serious allergic reaction, such as swelling of the face, lips, tongue, or throat, trouble breathing, or a severe rash.
Other serious side effects can include chest pain or pressure that could signal a heart attack, irregular heartbeat, sudden severe stomach pain or bloody diarrhea (which may be a sign of reduced blood flow to the bowel), sudden weakness, slurred speech, or vision changes (possible signs of stroke), and serotonin syndrome when Maxalt is taken with other serotonergic medications.
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (e.g., different shape or color), as trademark laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
