Mizollen is used to reduce the symptoms of:

  • hay fever (seasonal allergic rhinoconjunctivitis)
  • other allergic reactions causing irritation of the eyes and nose (perennial allergic rhinoconjunctivitis)
  • urticaria (an itchy skin rash, like nettle rash).

2. What you need to know before you take Mizollen.

Do not take Mizollen

  • if you are allergic to mizolastine or any of the other ingredients of this medicine (listed in section 6)
  • if you are taking a macrolide antibiotic (such as erythromycin, clarithromycin, azithromycin)
  • if you are taking an imidazole antifungal medicine (such as ketoconazole, fluconazole, itraconazole, used to treat fungus infections)
  • if you have liver problems
  • if you have heart problems
  • if you have ever had an irregular heart beat or a slow heart rate
  • if you have an abnormal ECG (electrical recording of your heart beat)
  • if you are already taking medicines for an irregular heart beat
  • if you have abnormal levels of salts in the blood, in particular low potassium levels.

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

Warnings and precautions

In the elderly - Mizollen can make some people feel drowsy and cause a fast or irregular heart beat - these effects are more likely in the elderly.

Blood tests

Your doctor may carry out regular blood tests and other tests to check how well the medicine is working for you. This is more likely if:

  • You have diabetes (your blood sugar level is uncontrolled).
  • The levels of salt substances in your blood sometimes change (electrolyte imbalance).
  • You have problems with your heart beat (cardiac arrhythmias).

Other medicines and Mizollen

Tell your doctor or pharmacist if you are taking, or have recently taken:

  • a macrolide antibiotic such as erythromycin, clarithromycin, azithromycin
  • an imidazole antifungal medicine, such as ketoconazole, fluconazole, itraconazole.

These medicines should not be taken with Mizollen.

You should also tell your doctor or pharmacist if you are taking:

  • cimetidine (used to treat stomach ulcers)
  • ciclosporin (an immunosuppressant)
  • nifedipine (used to treat high blood pressure or heart disease) because these drugs can affect the levels of Mizollen (mizolastine) in your blood.

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

Mizollen with food and drink

Mizollen can be taken with food or in between meals.

Mizollen does not alter the effects of alcohol. However, just like with any other medicine, you should not drink alcohol in excess when taking Mizollen.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine.

The safety of Mizollen in human pregnancy has not been established. As with all medicines, Mizollen should be avoided in pregnancy, particularly during the first three months. Mizolastine passes into breast milk, therefore Mizollen should not be used during breast-feeding.

Driving and using machines

You may feel sleepy after taking this medicine. If this happens, do not drive or use any tools or machines.

Mizollen contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking Mizollen.
