Imigran (Sumatriptan)

Sumatriptan works by selectively stimulating serotonin 5‑HT1B and 5‑HT1D receptors on cranial blood vessels and trigeminal nerve endings. This causes vasoconstriction of dilated intracranial vessels and blocks release of inflammatory neuropeptides, interrupting the migraine cascade and alleviating pain.

The prescribed dose of Imigran is determined by the treating physician. In clinical practice, a single 6 mg subcutaneous injection is often used for an acute migraine episode, but the exact regimen, including repeat dosing, must follow the prescriber’s instructions.

Imigran is classified as pregnancy category C, meaning risk cannot be ruled out and it should only be used if the potential benefit justifies the potential risk to the fetus. Safety during breastfeeding has not been fully established; mothers should consult their healthcare provider before use.

To order Imigran, submit an enquiry on the product page at gnhindia.com with the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain where applicable) and necessary import documentation.

Imigran belongs to the triptan class, which provides faster and more migraine‑specific relief than non‑specific analgesics such as NSAIDs. Compared with oral triptans, the subcutaneous injection offers a quicker onset of action, making it useful for patients who need rapid symptom control or who have difficulty swallowing tablets.

Imigran should be stored at ambient temperature, below 25 °C, in its original packaging to protect it from moisture and light. Do not freeze the product. Keep the vial in a dry place and discard any solution that appears discolored or contains particles.

Imigran is administered as a single subcutaneous injection, typically into the outer thigh or abdomen. The injection should be given using a sterile needle, following aseptic technique. Patients or caregivers should be trained by a healthcare professional on proper injection technique and disposal of sharps.

The most serious risks include coronary vasospasm that can lead to chest pain or myocardial infarction, serotonin syndrome when combined with other serotonergic drugs, and severe allergic reactions such as anaphylaxis. Patients should seek immediate medical attention if they experience chest discomfort, severe hypertension, or signs of an allergic reaction.

Imigran is contraindicated in patients with a history of ischemic heart disease, uncontrolled hypertension, peripheral vascular disease, hemiplegic or basilar migraine, and those currently taking MAO inhibitors. It should also be avoided in patients with known hypersensitivity to sumatriptan or any component of the formulation.
