1.    What Benph is and what it is used for

Your medicine contains terazosin, which belongs to a group of medicines called alpha-blockers. Benph is given to men suffering from an enlarged prostate gland (part of the male sexual organs found just below the bladder, which can place pressure on the bladder, causing problems, when passing water (urine)), as it can relax the muscles allowing urine to be passed more easily.

2.    What you need to know before you take Benph

Do not take Benph:

•    if you are allergic to terazosin or any of the other ingredients of this medicine (listed in section 6)

•    if you have ever taken a similar medicine to terazosin (eg. prazosin, alfuzosin, indoramin, tamsulosin, doxazosin) and you suffered an allergic reaction

•    if you have heart failure which may be caused by heart valve disease, a blood clot in the lungs or the membrane (protective lining) around the heart being inflamed (pericarditis).

Warnings and precautions

Talk to your doctor or pharmacist before taking Benph:

•    if you have fallen over or fainted whilst passing water

•    if you have had or are suffering from other heart conditions eg. heart disease, heart valve disease, angina, heart failure or stroke

•    if you are on a low salt (e.g. sodium) diet or —=|— are very dehydrated (e.g. you may have had

severe diarrhoea or been sick)

•    if you have severe liver or kidney problems

•    if you have had or are currently suffering from eye problems due to high blood pressure

•    if you have diabetes that requires insulin treatment

Tell your doctor if any of the above apply to you. During treatment

When taking this medicine you may experience a sudden drop in blood pressure when you stand up, shown by dizziness, weakness or sweating within a few hours of taking (this may occur especially after taking the first dose or during the early stages of treatment or when treatment is stopped and then restarted). If you experience a drop in blood pressure you should lie down with your legs and feet up in the air until the symptoms have disappeared. Usually, these effects last for only a short time.

This medicine can cause painful erections, which may last for hours and continue even after sex or masturbation (if left untreated this can cause problems with getting and maintaining an erection).

If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your eye specialist before the operation that you are taking or have previously taken this medicine. This is because terazosin may cause complications during the surgery which can be managed if your specialist is prepared in advance.

Other medicines and Benph

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription or the following:

•    medicines to lower blood pressure

(e.g. diltiazem), ACE inhibitors (e.g. ramipril) or other alpha-blockers (e.g. doxazosin, alfuzosin)

•    diuretics (water tablets) e.g. furosemide

•    medicine to thin the blood e.g. warfarin

•    medicine for erectile dysfunction (impotence) (e.g. sildenafil, tadalafil, vardenafil)

•    anti-inflammatory painkillers e.g. ibuprofen, diclofenac.

Some patients who take alpha-blocker therapy for the treatment of prostate enlargement may experience dizziness or light-headedness, which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking medicines for erectile dysfunction (impotence) with alpha-blockers. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of your alpha-blocker before you start medicines for erectile dysfunction.

Benph with alcohol

Alcohol can increase the effects of this medicine causing dizziness or fainting. Do not drink alcohol while taking this medicine if you are affected.

Pregnancy and breast-feeding

Benph is used to treat a condition found only in men. It should not be prescribed to women.

Driving and using machines

Benph may make you feel dizzy, light headed and drowsy. These side effects are more likely at the start of treatment, or in the case of missed doses and where treatment has been stopped and then restated again. You may also suffer from blurred vision or other eyesight changes. Do not drive, operate machinery or perform any hazardous tasks for 12 hours when you first start taking your medicine, or when your doctor increases the dose you are taking. After this time, make sure you are not suffering any of these side effects before carrying out these tasks.

Benph contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

Benph 5 mg and 10 mg tablets contain sunset yellow (E110)

Sunset yellow (E110), may cause allergic reactions.

3. How to take Benph

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

•    Swallow the tablets whole with a full glass of water

•    Take with or without food

•    Do not chew, break or crush the tablets.

Adults and the elderly (over 65 years of age) only:

The recommended starting dose is 1 mg of Benph. Take the very first dose at bedtime as Benph may make you feel dizzy or faint when taken for the first time.

Your doctor may adjust your dose depending on how you respond to the tablets. If your doctor increases your dose, he or she may double your dose at intervals of one week or every two weeks. The usual maintenance dose is 5 to 10 mg once daily. The maximum daily dose is 10 mg of Benph.

Use in children and adolescents (under 18 years):

There is no relevant use in children and adolescents under 18 years.

If you take more Benph than you should

If you take more Benph than you should your blood pressure may suddenly drop and you may feel dizzy or even faint. If you begin to feel dizzy, lie down until you feel better.

If the symptoms do not disappear, contact your doctor or nearest hospital casualty department immediately. Take any remaining tablets and the container with you.

If you forget to take Benph

If you forget to take Benph, do not take a double dose to make up for a forgotten dose as this may cause a sudden drop in blood pressure, especially if you take blood pressure lowering medicines, just carry on as before.

If for any reason, you have stopped taking Benph for several days, do not continue your treatment using the same dose. Contact your doctor as you may need to start taking your medicine at a lower strength than you have been used to taking.

If you stop taking Benph

Do not suddenly stop taking your medicine as this may cause serious changes in your blood pressure. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
