Moxonidine is a medicine which works on your blood vessels. You will have been prescribed it for presión arterial alta (hipertensión). Most people with high blood pressure do not feel unwell, but it is important that high blood pressure is treated even if you feel fine. This is because high blood pressure can be damaging to your blood vessels and can put a strain on your heart. If left untreated, high blood pressure is a risk factor that can increase your chance of developing heart disease, a stroke, and other serious conditions. It is likely that you will be prescribed moxonidine if other (more frequently used) medicines are not suitable for you, or if they have not been sufficient to control your high blood pressure.

Moxonidine works by relaxing the muscles in the walls of your blood vessels. This means that your blood vessels widen, which reduces your blood pressure and allows blood and oxygen to circulate more freely around your body.

Before taking moxonidine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking moxonidine it is important that your doctor knows:

  • Si estás embarazada o amamantando.

  • If you have a heart disorder, such as a slow heartbeat or heart failure.

  • If you have angina chest pain.

  • Si tienes un problema con el funcionamiento de tus riñones.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

  • Si alguna vez has tenido una reacción alérgica a un medicamento.

How to take moxonidine

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about moxonidine and will provide you with a full list of the side-effects which you could experience from taking it.

  • Take moxonidine exactly as your doctor tells you to. It is usual to start by taking one tablet of 200 micrograms each day, in the morning. If it is necessary, your doctor will then increase your dose after a few weeks. You may be asked to take either a higher strength of tablet, or to take two tablets a day. Increasing the dose slowly like this allows your doctor to make sure that you have the dose that helps your condition but avoids any unwanted symptoms.

  • Try to take your doses at the same time(s) of day each day, as this will help you to remember to take moxonidine regularly. If you are asked to take one dose a day, take it in the morning. If you are asked to take two doses a day, take your first dose in the morning and the second dose in the evening.

  • Swallow the tablet whole with a drink of water. You can take moxonidine either before or after a meal.

  • Si olvida tomar una dosis, tómela tan pronto como lo recuerde (a menos que esté cerca la hora de su próxima dosis, en cuyo caso omita la dosis olvidada). No tome dos dosis juntas para compensar una dosis olvidada.

Obteniendo el máximo de tu tratamiento

  • Intenta mantener tus citas regulares con tu médico. Esto es para que tu médico pueda verificar tu progreso.

  • There are three different strengths of moxonidine tablets available - 200 micrograms, 300 micrograms and 400 micrograms. Each time you collect a fresh supply of tablets it is a good idea to check to make sure you receive the strength you are expecting. If you have any questions, please ask your pharmacist to advise you.

  • Drinking alcohol while you are on moxonidine is not recommended. Alcohol will add to the blood pressure-lowering effect of moxonidine which will increase the chances of you experiencing side-effects such as feeling dizzy.

  • If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because some medicines (such as some anti-inflammatory painkillers) can interfere with the way moxonidine works.

  • If you are due to have an operation or dental treatment, it is important to tell the person carrying out the treatment that you are taking moxonidine. This is because some anaesthetics can affect your blood pressure.

  • Your doctor will advise you on what lifestyle changes you can make to help your condition. These may include losing weight if you are overweight, taking regular exercise, eating a healthy diet, cutting back if you drink a lot of alcohol, stopping smoking, and reducing the amount of salt in your meals and caffeine in your drinks. It is important that you follow any advice you are given.

  • Treatment with moxonidine is usually long-term unless you experience an adverse effect. Continue to take the tablets unless your doctor tells you to stop. Stopping treatment suddenly can cause problems in some people, so your doctor may want you to reduce your dose gradually if this becomes necessary.

What should I do if I need surgery or dental work while taking moxonidine?

If you are scheduled for an operation or dental treatment, it is important to inform the healthcare professional performing the treatment that you are taking moxonidine. This is because certain anaesthetics can affect your blood pressure.

Are there different strengths of moxonidine tablets, and how can I ensure I have the correct one?

Yes, moxonidine tablets are available in three different strengths: 200 micrograms, 300 micrograms, and 400 micrograms. Each time you receive a new supply of tablets, it's a good idea to check to make sure you have the expected strength. If you have any questions, you can ask your pharmacist for advice.

Why do I need to keep taking moxonidine even if my blood pressure feels normal?

Most people with high blood pressure do not feel unwell, but it must be treated even if you feel fine.
