1. What Zomig is and what it is used for

Zomig contains zolmitriptan and belongs to a group of medicines called triptans.

Zomig is used to treat migraine headache.

  • Migraine symptoms may be caused by swollen blood vessels in the head. Zomig is thought to reduce the widening of these blood vessels. This helps to take away the headache and other symptoms of a migraine attack, such as feeling or being sick (nausea or vomiting) and being sensitive to light and sound.
  • Zomig works only when a migraine attack has started. It will not stop you from getting an attack.

2. What you need to know before you take Zomig

Do not take Zomig:

  • If you are allergic (hypersensitive) to zolmitriptan or any of the other ingredients of this medicine (listed in Section 6).
  • If you have high blood pressure.
  • If you have poor blood circulation, usually affecting the legs and arms (peripheral vascular disease).
  • If you have ever had heart problems, including a heart attack, angina (chest pain caused by exercise or effort), Prinzmetal’s angina (chest pain which happens at rest) or have experienced heart related symptoms such as shortness of breath or pressure over the chest.
  • If you have had a stroke or short-lasting symptoms similar to stroke (transient ischaemic attack or TIA).
  • If you are at the same time taking some other medicines for migraine (e.g. ergotamine or ergot-type medicines like dihydroergotamine and methysergide) or other triptan medicines for migraine. See section below: ‘Taking other medicines’ for further information.
  • If you have severe kidney problems.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.


Warnings and precautions

Talk to your doctor or pharmacist before taking Zomig:

  • If you are at risk of getting ischaemic heart disease (poor blood flow in the arteries of the heart). Your risk is greater if you are a man over 40 or a woman who has reached the menopause, if you smoke, have high blood pressure, high levels of cholesterol or diabetes or if anyone in your family has ischaemic heart disease.
  • If you have been told that you have Wolff-Parkinson-White Syndrome (a type of abnormal heart beat).
  • If you have ever had liver problems.
  • If you have headaches which are not like your usual migraine headache.

If you go into hospital tell the medical staff you are taking Zomig.

Zomig is not recommended for people over 65 years.


Children and adolescents

Zomig is not recommended for people aged under 18 years

As with other migraine treatments, using too much Zomig can cause daily headaches or can make your migraine headaches worse. Ask your doctor if you think that this is the case for you. You may need to stop taking Zomig to correct the problem.


Other medicines and Zomig

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes herbal medicines and medicines you buy without prescription.

In particular, tell your doctor if you are taking any of the following medicines:

Medicines for migraine

  • If you take a triptan other than Zomig (such as sumatriptan or naratriptan) leave 24 hours before taking Zomig.
  • After taking Zomig leave 24 hours before taking another triptan.
  • If you take medicines containing ergotamine or ergot-type medicines (such as dihydroergotamine or methysergide), leave 24 hours before taking Zomig.
  • After taking Zomig leave 6 hours before taking ergotamine or ergot-type medicines.
    Medicines for depression
  • Mono-Amine Oxidase Inhibitors, also known as MAOIs (such as moclobemide).
  • SSRIs (selective serotonin reuptake inhibitors) such as fluoxetine, paroxetine, fluvoxamine or sertraline.
  • SNRIs (serotonin norepinephrine reuptake inhibitors) such as venlafaxine or duloxetine.

Serotonin syndrome is a rare, life-threatening condition that has been reported in some patients who took Zomig in combination with so called serotoninergic medicines (e.g. certain medicines for the treatment of depression). Signs of serotonin syndrome may be for example, agitation, tremor, restlessness, fever, excessive sweating, twitching, muscle rigidity uncoordinated movement of limbs or eyes and uncontrollable jerking of muscles. Your doctor may advise you on this.

Other medicines

  • Cimetidine (for indigestion or stomach ulcers).
  • A quinolone antibiotic (such as ciprofloxacin).

During a migraine attack your reactions may be slower than usual. Bear this in mind when you drive or use any tools or machines. Zomig is unlikely to affect driving or using tools or machines. However, it may make you feel sleepy. Wait to see how Zomig affects you before you try these activities.
