Naratriptan is a Triptan indicated for the acute management of migraine within the migraine disease pathway.

- Migraine without aura: provides rapid relief of headache intensity and associated symptoms. - Migraine with aura: reduces the severity of headache following aura onset. - Acute migraine attacks: enables patients to abort an attack when taken early.

Naratriptan may cause a range of adverse reactions, which are categorized by frequency.

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Fatigue: feeling unusually tired or weak. - Nausea: mild stomach upset or urge to vomit. - Dry mouth: reduced salivation leading to a parched feeling. - Tingling sensation: paresthesia in extremities.

Serious or Rare Side Effects: - Chest discomfort: pressure or pain that may mimic cardiac events. - Severe hypertension: sudden increase in blood pressure. - Serotonin syndrome: agitation, hyperthermia, and neuromuscular abnormalities. - Allergic reactions: rash, itching, swelling, or anaphylaxis. - Vasospasm: constriction of blood vessels causing ischemic symptoms.

When prescribing Naratriptan, clinicians should observe several precautionary measures to ensure patient safety. - Cardiovascular disease: avoid use in patients with uncontrolled hypertension, coronary artery disease, or history of stroke. - Concomitant serotonergic drugs: assess risk of serotonin syndrome when combined with SSRIs, SNRIs, or MAO inhibitors. - Hepatic impairment: consider dose adjustment or alternative therapy in moderate to severe liver dysfunction. - Age considerations: use with caution in elderly patients due to increased sensitivity to vascular effects. - Pregnancy and lactation: evaluate risk–benefit ratio; limited data are available. - Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and direct sunlight.

Naratriptan can interact with other medicines, and interactions are classified by their clinical significance.

Major Interactions (Avoid): - Ergot alkaloids: concurrent use may cause additive vasoconstriction and severe hypertension. - Monoamine oxidase inhibitors (MAOIs): increase risk of serotonin syndrome.

Moderate Interactions (Monitor Closely): - Selective serotonin reuptake inhibitors (SSRIs) and serotonin‑norepinephrine reuptake inhibitors (SNRIs): may elevate serotonin levels. - Antihypertensive agents: Naratriptan may reduce the effectiveness of blood pressure‑lowering drugs. - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): can raise plasma concentrations of Naratriptan.
