You may need urgent medical attention.
If you take too many MINAX XL tablets, your blood pressure may drop too far. You will feel faint or may faint and your heart
rate will also slow down. You may also have nausea, vomiting and shortness of breath. In extreme cases, serious heart and
lung problems may occur.
While you are taking MINAX XL
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking MINAX XL.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
Your blood pressure may drop suddenly if MINAX XL interacts with the anaesthetic.
If you become pregnant while taking this medicine, tell your doctor immediately.
If you have a severe allergic reaction to foods, medicines or insect stings, tell your doctor immediately.
If you have a history of allergies, there is a chance that MINAX XL may cause allergic reactions to be worse and harder to
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
You may feel light-headed or dizzy when you begin to take MINAX XL. This is because your blood pressure has fallen suddenly.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position
and blood pressure. If this problem gets worse or continues, talk to your doctor.
If you feel a worsening of your condition in the early stages of taking MINAX XL.
Some people may experience an apparent worsening of their condition in the early stages of treatment with MINAX XL. It is
important to tell your doctor if this happens to you, although it is usually temporary. If your condition continues to worsen,
you should see your doctor as soon as possible.
Make sure you drink enough water during exercise and hot weather when you are taking MINAX XL, especially if you sweat a lot.
If you do not drink enough water while taking MINAX XL, you may feel faint or light-headed or sick. This is because your blood
pressure is dropping too much. If you continue to feel unwell, tell your doctor.
If you are being treated for diabetes, make sure you check your blood sugar level regularly and report any changes to your
MINAX XL may change how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar (hypoglycaemia).
MINAX XL may increase the time your body takes to recover from low blood sugar. Your doses of diabetic medicines, including
insulin, may need to change.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked.
Things you must not do
Do not take MINAX XL to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor.
Your doctor may want you to gradually reduce the amount of MINAX XL you are taking before stopping completely. This may help
reduce the possibility of your condition worsening or other heart complications occurring.
Things to be careful of
Be careful driving or operating machinery until you know how MINAX XL affects you.
As with other beta-blocker medicines, MINAX XL may cause dizziness, light-headedness, tiredness, or drowsiness in some people.
Make sure you know how you react to MINAX XL before you drive a car, operate machinery, or do anything else that could be
dangerous if you are dizzy or light-headed.
Be careful when drinking alcohol while you are taking this medicine.
If you drink alcohol, dizziness or light-headedness may be worse.
Dress warmly during cold weather, especially if you will be outside for a long time (for example when playing winter sports).
MINAX XL, like other beta-blocker medicines, tends to decrease blood circulation in the skin, fingers and toes. It may make
you more sensitive to cold weather, especially if you have circulation problems.

By following these simple measures, you can further reduce the risk from heart disease.
