About tamsulosin

The prostate gland commonly becomes larger in older men. El agrandamiento de la glándula prostática también se llama hiperplasia prostática benigna (HPB). The prostate is situated close to the bladder, so its enlargement can cause problems with passing urine. Common symptoms that are experienced are having to wait before your urine starts to flow, taking longer at the toilet, dribbling urine, and a feeling that your bladder is not quite empty.

Tamsulosin works by relaxing the muscles around your bladder and prostate gland so that you can pass urine more easily.

Sometimes, more than one type of medicine is needed to control the symptoms of prostate enlargement. Tamsulosin is available in combination with other medicines for prostate enlargement. The combination brand called Combodart® contains tamsulosin with a medicine called dutasterida, and the combination brand called Vesomni® contains tamsulosin with a medicine called solifenacina. These brands may give better relief of symptoms than tamsulosin alone.

Tamsulosin is also available from pharmacies as a medicine called Flomax® Relief. The pharmacist will need to ask a number of questions about your medical history to make sure that tamsulosin is suitable for you. You will also need to be diagnosed by your doctor as having an enlarged prostate gland.

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

• If you ever feel dizzy or faint when you stand up, or if you have ever fainted after passing urine.

• If you need to have cataract eye surgery.

• Si tienes algún problema con el funcionamiento de tu hígado, o algún problema con el funcionamiento de tus riñones.

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

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

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

• Take tamsulosin exactly as your doctor or pharmacist tells you to. Swallow each dose with a drink of water - do not crush, break, or chew the tablets/capsules.

• Your first dose of tamsulosin may make you feel dizzy or faint, so it is important that you take it just before you go to bed. If you feel dizzy or weary, or if you start sweating, remain lying down until these symptoms have completely gone.

• Take one tablet/capsule every day. After the first dose, you can take your dose at a time of day that best suits you. Although you can take tamsulosin either before or after a meal, the usual advice is to take your doses after the same meal of the day each day.

• Si olvida tomar una dosis, tómela tan pronto como lo recuerde. Si no lo recuerda hasta el día siguiente, omita la dosis olvidada. No tome dos dosis al mismo tiempo para compensar una dosis perdida.

• Tamsulosin can cause dizziness particularly when you first start taking it. This may affect your ability to drive. Make sure your reactions are normal before you drive or do things which would be dangerous if you were not fully alert.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor may want to take your blood pressure from time to time, particularly when you first start the treatment.

• You are advised not to drink alcohol while you are on tamsulosin. Alcohol increases the risk of side-effects from tamsulosin, such as feeling faint or dizzy.

• Consider reducing or stopping the amount of caffeine you drink (commonly found in tea, coffee and cola). Caffeine can make your symptoms worse, so drinking less of these things may benefit you.

• If you are a smoker, stopping smoking may significantly improve your symptoms. This is because nicotine irritates the bladder. You can ask your doctor for advice on quitting.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking tamsulosin. This is because your blood pressure may drop suddenly if you have an anaesthetic. If you are having cataract surgery, it is particularly important that you tell your surgeon you are on tamsulosin. This is because an eye problem known as 'floppy iris syndrome' has developed in some people and your doctor may advise you to stop taking tamsulosin for a short while.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with tamsulosin. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to tamsulosin, speak with your doctor or pharmacist for further advice.

• Mantenga todos los medicamentos fuera del alcance y la vista de los niños.

• Almacenar en un lugar fresco y seco, lejos del calor y la luz directos.
