Imigran is used for the acute treatment of migraine attacks with or without aura. Imigran should only be taken after the onset of migraine symptoms. It should not be taken as a preventive measure.
2. Important information before taking Imigran
When not to take Imigran
- if the patient is allergic (hypersensitive) to sumatriptan or any of the other ingredients of this medicine (listed in section 6),
- if the patient has: symptoms of ischemic heart disease, Prinzmetal's angina (a type of ischemic heart disease), peripheral vascular disease, a history of myocardial infarction, stroke, or transient cerebral ischemic attack,
- if the patient has severe liver impairment,
- if the patient has moderate or severe hypertension or uncontrolled mild hypertension,
- if the patient is taking ergotamine or its derivatives, including methysergide (vasoconstrictor medicines used to treat migraine), or any other triptan or 5-HT receptor agonist (medicines used to treat migraine),
- if the patient is taking or has taken within the last 2 weeks monoamine oxidase inhibitor (MAOI) antidepressants (medicines used to treat depression and other mental health conditions).
Warnings and precautions
Before starting treatment with Imigran, the patient should tell their doctor if they have:
- headache, but migraine has not been previously diagnosed,
- headache that is different from the usual migraine headache,
- shortness of breath, pain, or feeling of pressure in the chest (which may radiate to the jaw or arms) of unknown cause,
- heart disease risk factors (men over 40, postmenopausal women, overweight, diabetes, high cholesterol, smokers, family history of heart disease),
- liver or kidney function disorders,
- history of seizures or predisposition to seizures,
- allergy to sulfonamide medicines, as sumatriptan may cause allergic reactions ranging from skin changes to anaphylactic shock,
- mild controlled hypertension, as a transient increase in blood pressure and peripheral vascular resistance may occur.
During concomitant use of sumatriptan and selective serotonin reuptake inhibitors (SSRIs) (antidepressants), serotonin syndrome has been rarely reported, including changes in mental status, autonomic dysfunction (symptoms related to abnormal functioning of the part of the nervous system responsible for involuntary functions, such as gastrointestinal and circulatory disorders, excessive sweating, and excessive salivation), and neuromuscular dysfunction. Serotonin syndrome has also been reported during concomitant use of triptans and SSRIs or serotonin-norepinephrine reuptake inhibitors (SNRIs) (antidepressants). If concomitant treatment with sumatriptan and an SSRI or SNRI is clinically justified, the patient should be under medical supervision.
Children and adolescents
Imigran is not recommended for use in children and adolescents.
Elderly patients
Imigran is not recommended for use in elderly patients (over 65 years of age).
Imigran and other medicines
The patient should tell their doctor about all medicines they are currently taking or plan to take.
After taking Imigran, the patient should not take any ergotamine or its derivatives for 6 hours, and any triptans or 5-HT receptor agonists for 24 hours. After taking any ergotamine or its derivatives, or any other triptan or 5-HT receptor agonist, the patient should not take Imigran for at least 24 hours.
The patient should not take Imigran with MAOIs or within 2 weeks of stopping treatment with MAOIs.
During concomitant use of sumatriptan and St. John's Wort (Hypericum perforatum) products, side effects may occur more frequently.

3. How to take Imigran
This medicine should always be taken exactly as prescribed by the doctor. If the patient is unsure, they should consult their doctor or pharmacist.
Imigran should only be taken after the onset of migraine symptoms, not as a preventive measure. The tablets should be swallowed whole with water.
The patient should not take more than the recommended dose.
The usual dose of Imigran is 50 mg, taken as soon as possible after the first symptoms of migraine appear. However, the medicine is equally effective when taken at any stage of the migraine attack. Some patients may require a 100 mg dose - they should follow their doctor's advice.
If the migraine symptoms do not improve after taking the first dose, taking a second dose during the same attack is not recommended. In such cases, the patient can take paracetamol, acetylsalicylic acid, or another non-steroidal anti-inflammatory drug (NSAID).
If the migraine symptoms recur, the patient can take another dose of Imigran, but not earlier than 2 hours after the first dose.
The patient should not take more than 300 mg in 24 hours.
