Nadolol

In Aotearoa New Zealand, nadolol comes as 40mg or 80mg tablets.

• The dose of nadolol will be different for different people depending on your condition and response to treatment.
• Always take nadolol exactly as your doctor has told you. 
• The pharmacy label on your medicine will tell you how much nadolol to take, how often to take it, and any special instructions.
  
  

• Timing: Take nadolol once a day at the same time each day.
• Food: You can take nadolol with or without food.
• Missed dose: If you forget your dose, take it as soon as you remember that day. But if it's nearly time for your next dose, just take the next dose at the right time. Don't take double the dose.

Here are some things to know when you're taking nadolol. Other things may be important as well, so ask your healthcare provider what you need to know about.

• Limit alcohol while you are taking nadolol, especially when you first start treatment. Alcohol can increase your risk of side effects, eg, dizziness.
• Be careful when driving or using tools until you know how this medicine affects you.
• Other medicines – nadolol interacts with many other medicines including common anti-inflammatories, eg, diclofenac, ibuprofen or aspirin. Check with your doctor or pharmacist before starting nadolol or taking any other medicines.
• It may also interact with herbal supplements and rongoā Māori, so check with your healthcare provider before starting any new products.
• Tell your doctor immediately if you become pregnant or want to start breastfeeding.
• Surgery – tell your healthcare providers you're taking nadolol if you have any surgical procedure planned including dental treatments.
• Don’t stop taking nadolol suddenly as this can be dangerous and make you feel unwell. Talk to your doctor before stopping, they may want to reduce your dose gradually.

If you have diabetes

• If you have diabetes, nadolol may cause changes in your blood glucose level. This effect usually settles with time.
• Nadalol and other beta-blockers may reduce the warning signs of a low blood glucose level (hypoglycaemia – often called a hypo). For example, you may not have the feeling of fast, irregular or strong heartbeats (palpitations) or tremor, which can occur when your blood glucose is going too low.
• If you are worried about this, talk to your doctor. Don't stop taking your beta-blocker without checking with your doctor first. Read more about hypoglycaemia(external link).

If you have asthma

• If you have asthma, taking nadalol or another beta-blocker may trigger your asthma symptoms or make them worse. However, not everybody with asthma is sensitive to these medicines.
• If you're worried about this, talk to your doctor. They may be able to prescribe a different medicine or increase the dose of your asthma preventer medication.

Like all medicines, nadolol can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
