Rizact, containing the active ingredient rizatriptan, is a prescription medication specifically designed for the acute treatment of migraine attacks with or without aura in adults. It belongs to the class of drugs known as selective serotonin receptor agonists (triptans), which work by narrowing blood vessels around the brain and reducing substances in the body that can trigger migraine pain, nausea, sensitivity to light and sound, and other migraine symptoms. Rizact is not intended for the prevention of migraines or for the treatment of cluster headaches, and it should be used only when a clear diagnosis of migraine has been established.
Features
- Contains rizatriptan benzoate as the active pharmaceutical ingredient
- Available in orally disintegrating tablet and standard oral tablet formulations
- Rapid disintegration and absorption profile for the orally disintegrating form
- Precisely calibrated 5 mg and 10 mg dosage strengths
- Formulated with patient-friendly excipients for stability and tolerability

Benefits
- Provides rapid relief from acute migraine headache pain, often within 30 minutes to 2 hours
- Effectively reduces associated migraine symptoms, including nausea, photophobia, and phonophobia

- Enables patients to resume normal daily activities more quickly following a migraine attack
- Provides a well-tolerated treatment option for many migraine sufferers when used as directed
- Supported by extensive clinical data demonstrating efficacy in acute migraine management
Common use
Rizact is commonly used for the acute treatment of migraine attacks in adults. It is specifically indicated for migraines with or without aura. Patients should take Rizact at the first sign of migraine symptoms for optimal effectiveness. It is not to be used for preventing migraines or for treating other types of headaches, such as tension headaches or cluster headaches. The medication is intended for intermittent use during migraine episodes rather than daily administration.
Dosage and direction
The recommended dose is 5 mg or 10 mg taken as a single dose at the onset of migraine symptoms. If the migraine returns or if there is only partial response, a second dose may be taken after at least 2 hours, not to exceed 30 mg in any 24-hour period. The orally disintegrating tablet should be placed on the tongue and allowed to dissolve, then swallowed with saliva—no liquid is needed. The standard tablet should be swallowed whole with water. Dosage adjustment may be necessary for patients on MAO inhibitors or with hepatic impairment. The maximum recommended single dose is 10 mg.
Precautions
Patients should be carefully evaluated for cardiovascular status before prescribing, as triptans may cause coronary vasospasm. Use with caution in patients with risk factors for coronary artery disease unless cardiovascular evaluation provides satisfactory results. May cause sensations of tightness, pain, or pressure in the chest, throat, neck, or jaw—typically non-cardiac but requires evaluation if severe or concerning. Monitor for serotonin syndrome, particularly when used with other serotonergic drugs. Use cautiously in patients with hepatic impairment, pregnancy, or breastfeeding. May cause dizziness or drowsiness—caution when operating machinery. Not recommended for use in patients with basilar or hemiplegic migraine.
Contraindications
Rizact is contraindicated in patients with ischemic heart disease, history of myocardial infarction, or documented silent ischemia. Contraindicated in patients with coronary artery vasospasm, including Prinzmetal’s angina. Should not be used in patients with uncontrolled hypertension. Contraindicated in patients with cerebrovascular syndromes including strokes and transient ischemic attacks. Not to be used in patients with peripheral vascular disease. Contraindicated within 24 hours of treatment with another triptan or ergotamine-containing medication. Contraindicated in patients with severe hepatic impairment. Should not be used in patients with known hypersensitivity to rizatriptan or any component of the formulation.
Possible side effects
Most common side effects include dizziness, somnolence, fatigue, nausea, and chest/neck/jaw tightness or pain. Less frequently reported effects include palpitations, tachycardia, hypertension, dry mouth, diarrhea, and muscle weakness. Rare but serious side effects may include coronary artery vasospasm, myocardial ischemia, myocardial infarction, ventricular tachycardia, ventricular fibrillation, cerebrovascular events, gastrointestinal ischemic events, and serotonin syndrome. Some patients may experience sensations of tingling, heat, or cold.
Drug interaction
Significant interactions occur with MAO inhibitors—concurrent use contraindicated (wait至少 2 weeks after discontinuing MAOI). Ergot-containing medications may cause prolonged vasospastic reactions—avoid within 24 hours of Rizact use. Other triptans should not be used within 24 hours of Rizact administration. Propranolol increases rizatriptan concentrations—use 5 mg dose with maximum daily dose of 10 mg. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) may increase risk of serotonin syndrome. Oral contraceptives may slightly decrease rizatriptan clearance.
Missed dose
Rizact is taken on an as-needed basis for acute migraine attacks and does not follow a regular dosing schedule. Therefore, the concept of a “missed dose” does not apply. Patients should take Rizact at the onset of migraine symptoms. If a dose is not taken during a migraine attack, simply take it when needed for the next migraine episode, following the same dosing instructions.
Overdose
Symptoms of overdose may include dizziness, drowsiness, fainting, tachycardia, bradycardia, hypotension, hypertension, seizure, and respiratory depression. In cases of suspected overdose, provide supportive care including continuous ECG monitoring for at least 20 hours. Ensure adequate airway and ventilation. Hemodialysis is unlikely to be beneficial due to extensive protein binding. Contact a poison control center for latest guidance on management.
Storage
Store at room temperature between 15-30°C (59-86°F). Protect from light and moisture. Keep orally disintegrating tablets in the original blister package until time of use. Keep all medications out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused medication that is no longer needed or has expired.
Disclaimer
This information is for educational purposes only and does not constitute medical advice. Always consult with a qualified healthcare professional before starting any new medication. The prescribing physician should be aware of the patient’s complete medical history and current medications. Individual response to medication may vary. Only a healthcare provider can determine if Rizact is appropriate for a specific patient.
Reviews
Clinical studies demonstrate that rizatriptan provides headache relief in up to 70% of patients within 2 hours of administration. Many patients report significant improvement in functional ability following treatment. The orally disintegrating formulation receives particular praise for its convenience and rapid onset of action. Some patients note the medication works best when taken early in the migraine episode. Healthcare providers appreciate the well-established efficacy and safety profile of rizatriptan in appropriate patient populations. The 10 mg dose generally shows higher efficacy than the 5 mg dose, though with slightly increased incidence of side effects.
