What is it and how do I use it?
Sumatriptan-Mepha solution for injection is used in the acute treatment of migraine attacks.
Sumatriptan Injection is also intended for the treatment of cluster headache (cluster migraine: unilateral pain, intense, of short duration, appearing in the form of seizures).
It is believed that migraine pain is caused by painful dilation and inflammation of blood vessels in the head. Sumatriptan-Mepha relieves migraine pain by narrowing the dilated blood vessels.
Sumatriptan-Mepha should not be used for the prevention (prophylaxis) of migraine or cluster headache.
Sumatriptan-Mepha solution for injection should only be used on prescription from a doctor.
What should you consider before using it?
Sumatriptan-Mepha solution for injection should not be used in case of hypersensitivity to any component of the drug, untreated hypertension, a history of myocardial infarction, kidney damage or serious liver disease, known circulation disorders in the heart (angina pectoris), brain and extremities.
Sumatriptan-Mepha solution for injection should not be used at the same time as the following medicines:
- MAO inhibitors (certain antidepressants or products for Parkinson’s disease). Treatment with Sumatriptan-Mepha should not be started until 2 weeks after stopping the MAO inhibitor.
- Migraine medications containing ergotamine or its derivatives (such as dihydroergotamine or methysergide, for example). During the 24 hours before and 6 hours after the administration of Sumatriptan-Mepha, products containing ergotamine should not be taken.
In rare cases, an effect called “serotonin syndrome” may occur when triptans, such as Sumatriptan-Mepha, are given together with other medicines with serotonergic effects. These include: certain antidepressants (eg medicines called selective serotonin reuptake inhibitors or selective serotonin / norepinephrine reuptake inhibitors, MAO inhibitors, L-tryptophan, lithium, tricyclic antidepressants, etc.). Tell your doctor if you are being treated with these medicines. “Serotonin syndrome” may include the following symptoms: increased excitability of intrinsic muscle reflexes, convulsive muscle movements, tremors, restlessness, anxiety, hallucinations, irritability leading to confusion and loss of consciousness, rapid heartbeat, fluctuations in blood pressure, nausea, vomiting, fever and diarrhea. Tell your doctor if any of these symptoms appear in you after taking Sumatriptan injection.
Simultaneous administration of Sumatriptan-Mepha and other specific migraine medications (called triptans) is not recommended.
Please tell your doctor or pharmacist if you suffer from any other disease such as high blood pressure or cardiovascular disease, blood circulation disorders, liver or kidney disease or epilepsy, if you are allergic or if you are already taking other medicines for internal or external use (even self-medication)!
If you are being treated with medicines called beta blockers which can also be used for migraine prophylaxis, your doctor will prescribe Sumatriptan-Mepha especially carefully.
Headaches may get worse if you use Sumatriptan-Mepha too often. In this case, your doctor may stop treatment with Sumatriptan injection.
This medicine may affect reactions, the ability to drive, and the ability to use tools or machines!
Drowsiness may also occur following migraine or its treatment with Sumatriptan-Mepha. Caution should therefore be exercised if you must drive a vehicle or use machines during treatment.
