Sumatriptan Bluefish – Sumatriptan uses, dose and side effects


50 mg tablets

What Sumatriptan Bluefish is and what it is used for

Sumatriptan Bluefish belongs to the drug group triptans.

Sumatriptan Bluefish is used to treat migraine attacks with or without aura (a premonition usually consisting of visual disturbances such as flashes, zigzag lines, stars, or waves). Sumatriptan Bluefish should only be used when you have signs or symptoms of a migraine attack. Migraine headaches are usually of moderate to severe intensity, unilateral (but can switch sides between attacks), and have a pulsating character. Symptoms such as nausea, sometimes vomiting, and significant sensitivity to light and sound are common in migraines.

Migraine symptoms are probably caused by a temporary dilation of the blood vessels in the head. Sumatriptan Bluefish is thought to reduce the dilation of these blood vessels. This contributes to the headache as well as other migraine symptoms, such as nausea, vomiting, and sensitivity to light and sound disappearing or being alleviated.

Sumatriptan Bluefish only works when a migraine attack has started. It does not stop an attack.

You must not use sumatriptan to prevent a migraine attack.

Sumatriptan Bluefish is not intended for the treatment of other types of headaches, such as tension-type headaches.

The sumatriptan contained in Sumatriptan Bluefish may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before taking Sumatriptan Bluefish

Sumatriptan Bluefish should only be used by you who know you have migraines.

You probably have a migraine if you have recurring headaches such as:

  • Has a pulsating character and is one-sided
  • Has moderate to the strong intensity and lasts for 4-72 hours
  • Worsens with normal physical activity (eg walking or climbing stairs)
  • Affects your ability to concentrate and your daily tasks

Migraine can be accompanied by other symptoms such as:

  • Nausea, sensitivity to light and sound
  • Aura symptoms, for example, visual field loss, zigzag patterns or flashes in the visual field, and less often numbness or speech difficulties.

Consult a doctor or pharmacist if you are unsure or need more information.

Warnings and precautions

Before treatment with Sumatriptan Bluefish, tell your doctor if:

  • you are a heavy smoker or use other nicotine products ( patches or nicotine gum), especially if you are a woman and have undergone menopause or are a man and over 40 years old. A medical examination should take place before the treatment is started.
  • you have liver or kidney failure. The dose may need to be adjusted.
  • you have ever had seizures/convulsions or are prone to seizures/convulsions? Sumatriptan can induce seizures/convulsions. Sumatriptan Bluefish may increase the risk of seizures.
  • you are hypersensitive to certain antibiotics (sulfa drugs). If you have had an allergic reaction after starting to take sumatriptan, Caution should be observed.
  • you use herbal remedies that contain St. John’s wort ( Hypericum perforatum ). Side effects may occur with greater frequency.

Sumatriptan Bluefish may only be used if you have been diagnosed with “migraine” and other factors have been ruled out. Some forms of migraine cannot be treated with sumatriptan. If the headache is not at all similar to your usual headache, you should not take Sumatriptan Bluefish without first consulting a doctor.

When taking Sumatriptan Bluefish, you may sometimes briefly feel pain and pressure in your chest. This can be a relatively intense feeling that can radiate up to the throat. In very rare cases, this may be due to the heart being affected. If the symptoms do not go away, you must contact your doctor.

Overuse of Sumatriptan Bluefish can cause chronic, daily headaches or worsening headaches. Consult your doctor if this is right for you.

Other medicines and Sumatriptan Bluefish

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

An interaction means that different medicines used at the same time can affect each other’s effects and/or side effects. This may also affect medicines that you have taken or will take shortly.

This should be especially taken into account when using:

  • medicines containing ergotamine (for migraines ) or other triptans. These must not be used at the same time as Sumatriptan Bluefish (see also “Do not use Sumatriptan Bluefish”). When you have taken medicines containing ergotamine or other triptans, it is inappropriate to take Sumatriptan Bluefish for 24 hours. After taking Sumatriptan Bluefish, it is inappropriate to take medicines containing ergotamine for 6 hours and at least 24 hours for medicines containing other triptans.
  • MAO inhibitors (eg moclobemide for depression or selegiline for Parkinson’s disease ). Sumatriptan Bluefish must not be used for two weeks after you stop using MAO inhibitors.
  • use of triptans together with selective serotonin reuptake inhibitors ( SSRIs ) and serotonin-norepinephrine reuptake inhibitors ( SNRIs ) may cause serotonin syndrome (a combination of symptoms that may include confusion, hallucination, restlessness, sweating and muscle cramps, and tremors). If you experience these symptoms, consult a doctor.
  • there is a risk that the simultaneous use of sumatriptan with lithium (used in the treatment of manic-depressive (bipolar) disorder) may cause serotonin syndrome.

Please note that the above-mentioned medicines may have other names, for example, brand names. In this section, only the drug or the active substance of the drug group is stated and not the brand name. Always carefully check the active substance or the drug’s treatment group on the package and the information in the package leaflet of the drug you are already using.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


Sumatriptan should only be used during pregnancy under the prescription of a doctor. Sumatriptan should only be used during pregnancy if the positive effects for the mother are greater than the potential risk to the fetus and no other forms of treatment are available.

Driving ability and use of machinery

Drowsiness can occur as a result of migraines or due to treatment with Sumatriptan Bluefish. This may affect your ability to drive or use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.
