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

Before starting treatment with DOXADURA your doctor may perform tests to rule out other conditions such as prostate cancer that may cause the same symptoms as benign prostatic hyperplasia (enlargement of the prostate gland).

Persistent painful erections may occur very rarely. If this happens you should contact a doctor immediately.

When you start to take DOXADURA you may experience faintness or dizziness caused by low blood pressure, when getting up from sitting or lying down. If you feel faint or dizzy, you should sit or lie down until you feel better and avoid situations where you might fall or hurt yourself.

Your doctor may want to measure your blood pressure regularly at the start of therapy to reduce the possibility of these effects happening.

DOXADURA is not recommended for use in children or adolescents below 18 years as safety and efficacy have not yet been established. Benign prostate hyperplasia is not relevant in children.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

There are some medicines that may interact with DOXADURA. Ask your doctor or pharmacist before use if you are taking any of these medicines as they may change the effect of DOXADURA.

Some patients who take alpha-blocker therapy for the treatment of high blood pressure or 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 called PDE 5 inhibitors for the treatment of erectile dysfunction (impotence) with alpha-blockers e.g. sildenafil, tadalafil, vardenafil (please see Section “Warnings and precautions”). 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 drugs for erectile dysfunction.

DOXADURA may lower your blood pressure even more if you are already taking other medicines to treat high blood pressure.

• Medicines to treat bacterial or fungal infections, e.g. clarithromycin, itraconazole, ketoconazole, telithromycin, voriconazole
• Medicines used in the treatment of HIV e.g. indinavir, nelfinavir, ritonavir, saquinavir
• Nefazodone, a medicine used to treat depression

Please refer to section 3.

You have been given a calendar pack that will help you remember to take your tablets. If you are taking more than one tablet a day, you must ignore the marking for the day, printed on the back of the blister.

Because high blood pressure is treated in order to prevent problems from arising, you may have no symptoms at all while taking DOXADURA. Even if this is so and you feel well, you should not stop taking your blood pressure medication unless instructed to by your doctor.

Don't change the dose or stop taking the tablets without first checking with your doctor.
