Before Using This Medicine
It is essential to inform your doctor about the following conditions to ensure safe treatment:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Describe the allergic reaction you experienced, including any symptoms.
Certain health conditions, including:

Recent use of certain medications for depression, including isocarboxazid, phenelzine, or tranylcypromine, within the last 14 days. Taking this medication within 14 days of these drugs can cause severe high blood pressure.
Use of other medications for migraine or headache, such as almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, or sumatriptan, within the last 24 hours.
Use of ergotamine, methysergide, dihydroergotamine, or similar medications within the last 24 hours.
Special Considerations for Children:
If you are under 18 years of age, inform your doctor. This medication is not approved for use in children younger than 18 years of age.
Interactions with Other Medications and Health Conditions:
This is not an exhaustive list of all potential interactions. It is crucial to inform your doctor and pharmacist about all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, as well as any health problems you have.
* Before starting, stopping, or changing the dose of any medication, consult with your doctor to ensure it is safe to take this medication with your other medications and health conditions.
Precautions & Cautions
Taking a higher dose or using this medication more frequently than prescribed by your doctor may lead to worsening of your headaches. As this class of medication can cause high blood pressure, it is crucial to have your blood pressure monitored as directed by your doctor. If you have risk factors for heart disease, such as high blood pressure, high cholesterol, being overweight, having high blood sugar or diabetes, smoking cigarettes, being a male over 40 years old, having a family history of early heart disease, or being a postmenopausal female, exercise caution and discuss your individual situation with your doctor.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects. Pregnant women, those planning to become pregnant, or breastfeeding mothers should consult their doctor to discuss the potential benefits and risks of this medication to both themselves and their baby.
Overdose Information
Overdose Symptoms:
- Severe drowsiness
- Dizziness
- Nausea
- Vomiting
- Hypertension
- Hypotension
- Tachycardia
- Bradycardia
- Vasospasm (including coronary vasospasm)
What to Do:
Call 1-800-222-1222 (Poison Control) immediately or seek emergency medical attention. Treatment is symptomatic and supportive. Monitor cardiac and respiratory function.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (concurrent use or within 2 weeks of discontinuing MAOI)
- Ergot-type drugs (e.g., ergotamine, dihydroergotamine) (within 24 hours)
- Other 5-HT1 agonists (e.g., sumatriptan, naratriptan) (within 24 hours)
Major Interactions
- Selective Serotonin Reuptake Inhibitors (SSRIs) / Serotonin Norepinephrine Reuptake Inhibitors (SNRIs) (increased risk of serotonin syndrome)
- Cimetidine (increases zolmitriptan Cmax and AUC)
Moderate Interactions
- Propranolol (slight increase in zolmitriptan AUC and Cmax, but no dose adjustment needed)
- Oral Contraceptives (no significant interaction)
Monitoring
Baseline Monitoring
Rationale: To identify patients at risk for coronary artery disease (CAD) or other cardiovascular events, as triptans can cause vasoconstriction.
Timing: Prior to initiating therapy, especially in patients with multiple risk factors.
Routine Monitoring
Frequency: With each use
Target: Significant reduction or elimination of migraine pain and associated symptoms.
Action Threshold: Lack of efficacy after appropriate dosing may warrant consideration of alternative treatments.
Frequency: With each use and during follow-up
Target: Absence or mild, transient nature of adverse effects.
Action Threshold: Persistent, severe, or unusual symptoms (especially chest pain, shortness of breath, or neurological changes) require immediate medical evaluation.
Symptom Monitoring
- Migraine pain intensity and associated symptoms (nausea, photophobia, phonophobia)
- Chest pain, tightness, or pressure (can indicate cardiac ischemia)
- Neck pain or tightness
- Paresthesias (tingling, numbness)
- Dizziness or vertigo
- Fatigue or somnolence
- Signs of serotonin syndrome (agitation, hallucinations, rapid heart beat, fever, overactive reflexes, nausea, vomiting, diarrhea, incoordination)
- Signs of stroke (sudden numbness or weakness, confusion, trouble speaking, vision problems, severe headache)
Special Patient Groups
Pregnancy
Zolmitriptan is classified as Pregnancy Category C. Animal studies have shown adverse effects on the fetus, but there are no adequate and well-controlled studies in pregnant women. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Zolmitriptan is excreted into breast milk. The amount is small, and adverse effects on breastfed infants are unlikely. However, caution is advised. Consider waiting 2-3 hours after a dose before breastfeeding to minimize infant exposure.
Pediatric Use
Not recommended for children under 12 years due to lack of efficacy and safety data. For adolescents 12-17 years, the oral disintegrating tablet formulation is approved, but with a lower maximum daily dose (5 mg/24 hours) compared to adults.
Geriatric Use
Use with caution in elderly patients (over 65 years) due to a higher likelihood of underlying cardiovascular disease. No specific dose adjustment is generally required based on age alone, but individual assessment of cardiovascular risk is important.
Clinical Information
Clinical Pearls
- Zolmitriptan is effective for acute migraine treatment but should not be used for migraine prevention.
- Advise patients to take the medication at the first sign of a migraine attack, but not during the aura phase if it precedes the headache.
- Counsel patients on the importance of not exceeding the maximum daily dose (10 mg in 24 hours) to avoid medication overuse headache.
- Screen patients for cardiovascular risk factors (e.g., hypertension, hyperlipidemia, diabetes, smoking, family history of CAD) before initiating triptan therapy.
- Inform patients about potential triptan-related sensations (e.g., chest pressure, neck tightness, tingling) which are usually mild and transient, but to seek immediate medical attention for severe or persistent symptoms.
- Avoid concomitant use with MAOIs, ergot derivatives, or other triptans due to increased risk of adverse events.
Alternative Therapies
- Other Triptans (e.g., sumatriptan, rizatriptan, eletriptan, frovatriptan, naratriptan, almotriptan)
- NSAIDs (e.g., ibuprofen, naproxen)
- Acetaminophen
- Combination analgesics (e.g., Excedrin Migraine)
- CGRP Receptor Antagonists (gepants like rimegepant, ubrogepant)
- Ditans (e.g., lasmiditan)
- Ergot Alkaloids (e.g., ergotamine, dihydroergotamine)
- Anti-emetics (for associated nausea/vomiting, e.g., metoclopramide, ondansetron)
