Sumatriptan SUN – Sumatriptan uses, dose and side effects


12 mg/ml solution 

for injection

What Sumatriptan SUN is and what it is used for

The active substance in Sumatriptan SUN is sumatriptan. It belongs to a group of medicines called 5HT 1 – receptor agonists.

Sumatriptan is used to treat migraine headaches and a rare condition called cluster headaches. The symptoms of migraine may be due to temporary swelling of the blood vessels in the head. Sumatriptan is thought to work by reducing the size of these blood vessels.

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

What you need to know before using Sumatriptan SUN

Do not use Sumatriptan SUN

  • if you are allergic to sumatriptan or any of the other ingredients of this medicine (listed in section 6).
  • if you have problems with your heart or if you have previously had a heart attack
  • if you have problems with blood circulation in the arms and legs
  • if you have had a stroke or a mini-stroke (also called a transient ischemic attack or TIA )
  • if you suffer from severe liver disease
  • if you have pronounced or uncontrolled high blood pressure
  • together with migraine medicines containing ergotamine or similar medicines such as methysergide or any other triptan or 5 – HT agonist
  • with MAO inhibitors ( monoamine oxidase inhibitors ) or if you have taken MAO inhibitors in the last two weeks.

Warnings and precautions

Talk to your doctor or pharmacist before using Sumatriptan SUN:

  • if you suffer from any of the following medical conditions: heart diseases such as heart failure, angina pectoris or coronary thrombosis (heart attack), high blood pressure, liver or kidney disease, epilepsy or brain disease (especially postmenopausal women and men over 40 should have their heart and blood vessels checked before using this medicine),
  • if you have any of the risk factors for heart disease such as family heart disease; diabetes mellitus; high blood cholesterol; if you smoke cigarettes regularly or if you are very overweight,
  • if you are allergic to certain antibiotics ( sulfonamides ); people who are allergic to sulfonamides may experience an allergic reaction to sumatriptan.
  • if you are using certain medicines to treat depression (so-called SSRIs or SNRIs ) or lithium (a medicine used to treat manic-depressive (bipolar) disorders). You may experience serotonin syndrome (including confusion, increased heart rate, tremors, sweating, and muscle twitching). Ask your doctor for advice if you notice any of these symptoms.

After you have discussed the above, it may happen that the doctor still advises you to use Sumatriptan SUN and shows you how to give yourself an injection.

As with other migraine treatments, using too much of the medication can make your migraines worse and make them happen more often.

You may only use Sumatriptan SUN when the doctor is sure that you suffer from migraine headaches or cluster headaches.

Other medicines and Sumatriptan SUN

Before using Sumatriptan SUN, tell the doctor if:

  • you are taking other medications for migraine that contain ergotamine or derivatives of ergotamine such as ergotamine tartrate or methysergide maleate (in which case you should stop taking them at least 24 hours before using Sumatriptan SUN),
  • you are taking any prescribed medication for the treatment of depression such as MAO inhibitors or SSRIs (including citalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline ) or if you have taken any MAO inhibitor in the last two weeks,
  • you are taking lithium (a medicine used to treat manic-depressive (bipolar) disorders),
  • you are taking any prescribed medications to help you lose weight or to treat epilepsy,
  • you are taking any natural remedy/natural medicine that contains St. John’s wort ( Hypericum perforatum ). Using this together with Sumatriptan SUN may increase the likelihood of side effects.

Tell your doctor or pharmacist if you are using, have recently used, or might be using other medicines.

Pregnancy and breastfeeding

Consult a doctor or pharmacist before using this medicine

  • if you are pregnant, think you may be pregnant or are planning to have a baby
  • if you are breastfeeding. The doctor may still advise you to take sumatriptan, but breastfeeding should be avoided for 12 hours after a dose has been taken, and during this time any expressed breast milk should be discarded.

Driving ability and use of machinery

Sumatriptan may cause drowsiness. If you are affected, do not drive or operate machinery.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. 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.

Sumatriptan SUN contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dose (ie 0.5 ml), i.e. it is almost ‘sodium-free’.

How to use Sumatriptan SUN

Always use this medicine as directed by your doctor. Ask your doctor or pharmacist if you are unsure.

Sumatriptan SUN is usually injected into the thigh.

Carefully read the section “How to use the pre-filled pen” at the end of this leaflet. With the pre-filled pen, a dose of Sumatriptan SUN is injected quickly and painlessly just under the skin. Injection one must NOT be given in any way other than as shown.

DO NOT inject Sumatriptan SUN into a blood vessel.

Do NOT use Sumatriptan SUN to try to prevent an attack.

For migraines:

Use a pre-filled pen at the first sign of a migraine attack ( however, dose one is equally effective regardless of when it is used during an attack). If the migraine goes away after the first dose but then comes back, you can use another pre-filled pen provided that at least one hour has passed since the first injection. Do NOT use more than TWO injections within 24 hours.

If the migraine is not relieved by the injection, you can then take your usual painkillers provided they do not contain ergotamine or its derivatives. Wait at least six hours after using Sumatriptan SUN before taking any medicines containing ergotamine or its derivatives.

If a migraine does not stop, do not use the medicine again for the same attack. Sumatriptan SUN can be used in the next attack.

For cluster headaches:

Use ONE pre-filled pen for each cluster attack. It should be used at the first sign of a cluster headache (although it is equally effective if used at any time during an attack). DO NOT use more than TWO injections in 24 hours and be sure to leave at least one hour between the two doses.

Use for children and adolescents (under 18 years)

Sumatriptan injection should not be used in children and adolescents under 18 years of age.

Use for the elderly (over 65)

There is little experience with injecting sumatriptan in people over 65, which is why it is not usually prescribed for this age group.

If you have used too much Sumatriptan SUN 

You can get sick if you use more than the prescribed dose. If you take an overdose DO NOT DELAY to ask the doctor what to do or contact the nearest emergency room.

If you have ingested too much medicine or if, for example, a child has ingested the medicine by mistake, contact a doctor, or hospital for an assessment of the risk and advice.

If you have any further questions about this medicine, ask your doctor or pharmacist.
