Fungal infections within the body sometimes occur and can be serious. You are more at risk of developing an internal fungal infection if your immune system does not work properly. For example, if you are taking chemotherapy, or if your immune system is being suppressed following stem cell transplant, or if you have HIV/AIDS.

Voriconazole is used for the treatment of serious fungal infections, particularly aspergillosis. Aspergillosis most commonly affects the lungs, but it can sometimes infect other organs too. Voriconazole works by stopping the growth of the fungi causing the infection.

Before taking voriconazole

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 voriconazole it is important that your doctor knows:

  • Si está embarazada o en periodo de lactancia.

  • Si tiene algún problema con el funcionamiento de su hígado, o si tiene algún problema con el funcionamiento de sus riñones.

  • If you have a heart condition, or any heart rhythm problem such as a slow or irregular heartbeat.

  • Si padece un raro trastorno sanguíneo hereditario llamado porfiria.

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

  • Si toma o utiliza otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

How to take voriconazole

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

  • Take voriconazole exactly as your doctor tells you to. It is taken twice daily. You should space the doses out evenly throughout the day, which means taking them twelve hours apart. Your doctor (or nurse if you are in hospital) will tell you how many tablets or how much medicine to take for each dose. During the first 24 hours of taking voriconazole you will be asked to take a higher dose than afterwards. This is to make sure you get the right amount of medicine into your bloodstream straightaway.

  • You should take voriconazole when your stomach is empty, which means that you should take your doses either an hour before a meal, or alternatively wait until two hours after you have eaten. This is because your body absorbs less of the medicine if it is taken at a mealtime, and this consequently means that the treatment is less effective for you.

  • If you have been given liquid medicine, use the oral syringe to measure out your doses. To do this, put the tip of the syringe into the adaptor in the neck of the medicine bottle. When it feels secure, turn the bottle and the syringe upside down. Slowly pull back the plunger on the syringe until it fills it with medicine up to the mark for your dose. Turn the bottle and syringe upright again and then remove the syringe from the bottle. Slowly empty the contents of the syringe into your mouth. Then wash and rinse the syringe.

  • If you forget to take a dose, leave out the missed dose but make sure that you remember to take your next dose when it is due. Do not take two doses together to make up for the forgotten dose.

  • Your doctor will tell you how long you will need the treatment for. Continue to take the medicine until the full course is finished (unless you are told otherwise by your doctor). This is to make sure that your infection has completely gone and also to prevent it from coming back.

Aproveche al máximo su tratamiento

  • Try to keep all your appointments with your doctor and clinic. This is so your doctor can check on your progress. Your doctor will want to do some blood tests during the treatment to check that your liver and kidneys are working properly.

  • Voriconazole can make your skin much more sensitive to sunlight than it is usually. You should protect your skin from sunlight, even on bright but cloudy days. If you notice any sunburn, or if you develop a skin rash on sun-exposed areas of your skin, please speak with a doctor about this as soon as you are able. Do not use sunbeds.

  • If you buy any medicines 'over the counter', please check with a pharmacist that they are suitable for you to take with voriconazole. This is because voriconazole can interfere with some medicines, including an anti-inflammatory painkiller called ibuprofen which can be bought without a prescription.

  • You must avoid getting pregnant while you are taking voriconazole. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner if this affects you.
