The name of this product is Slocinx XL 4mg Tablets (referred to as Slocinx XL throughout this leaflet).
It contains a medicine called doxazosin. This belongs to a group of medicines called alpha-blockers.
It can be used to treat:
• High blood pressure (hypertension). It works by relaxing the blood vessels so that the blood passes
through them more easily. This helps to lower your blood pressure.
• The symptoms caused by the enlargement of the prostate gland in men. Common symptoms are
poor or frequent passing of water (urine). Slocinx XL works by relaxing the muscle around the
urethra (the thin tube that carries urine from the bladder out of the body). This allows your water
(urine) to pass more easily.
Do not take Slocinx XL and tell your doctor if:
• You have ever suffered an allergic reaction to doxazosin or any of the other ingredients of
this medicine (listed in section 6).
Signs of an allergic reaction include itching, reddening of the skin or difficulty breathing.
• You know that you are sensitive to medicines like doxazosin – such as prazosin and terazosin.
• You are breast feeding.
• You have a benign prostatic enlargement and any kind of congestion or blockage in your urinary
tract (which includes your kidneys, bladder and urethra), an infection of the urinary tract or have
had bladder stones forming in your urine.
• You have kidney problems, you do not feel the urge to urinate (overflow incontinence) or your body
is not making any urine (anuria).
• You have or have ever had constipation or any kind of blockage in your gut (digestive tract).
• You have low blood pressure (hypotension) or if you have ever had orthostatic hypotension (a fall in
blood pressure on standing up which causes dizziness, light headedness or fainting).
Do not take if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist
before taking Slocinx XL.
Warnings and precautions
Talk to your doctor or pharmacist before taking Slocinx XL if:
• You have heart disease
• You have liver disease
• You take drugs for erectile dysfunction (impotence) (e.g. sildenafil, tadalafil, vardenafil). This is
because some patients may experience dizziness or light-headedness, which may be caused by
low blood pressure (see section “Other medicines and Slocinx XL”)
• You have something called ‘diabetic autonomic neuropathy’. This is a disease related to diabetes
which affects your nervous system
If you are going to have an anaesthetic (for an operation, or dental treatment), tell your doctor or
dentist you are taking Slocinx XL.
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 Slocinx XL. This is because
Slocinx XL may cause complications during the surgery which can be managed if your specialist is
prepared in advance.
At initiation of treatment with this medicine you may experience dizziness, weakness and in rare
occasions fainting. You should therefore be careful and avoid situations that could lead to injury if
these symptoms occur.
Children and adolescents
Slocinx XL is not recommended for use in children or adolescents below 18 years as safety and efficacy
have not yet been established.
Other medicines and Slocinx XL
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, including herbal medicines. This is because
Slocinx XL can affect the way some other medicines work. Also some medicines can affect the way
Slocinx XL works.
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 drugs 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 drugs for erectile dysfunction.
Tell your doctor if you are taking any of the following:
• Painkillers called non-steroidal anti-inflammatory drugs (NSAIDs) - such as ibuprofen
• Other medicines which lower blood pressure
• Medicines containing oestrogen - such as the contraceptive pill or hormone replacement therapy
• Medicines containing dopamine, metaraminol, methoxamine, adrenaline (epinephrine). Also,
medicines for coughs and colds (as they may contain ephedrine, phenylephrine)
Slocinx XL with food and drink
Slocinx XL can be taken with or after food.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask
your doctor or pharmacist for advice before taking this medicine. Taking Slocinx XL is not
recommended if you are pregnant or might become pregnant. Do not take this medicine if you are
Driving and using machines
Slocinx XL may affect your ability to drive or use any machinery, especially when you first start to take
your tablets. If affected, do not drive or use machines.
Always take this medicine exactly as your doctor or pharmacist has told you. You should check with
your doctor or pharmacist if you are not sure.
Slocinx XL is a modified release tablet. The active compound is surrounded by a non-absorbable shell
that has been specially designed to slowly release the medicine. Once swallowed, doxazosin is slowly
released into the body from the tablet, until the tablet shell is empty. The empty tablet shell is excreted,
you may occasionally observe in the stools something that looks like a tablet. This is to be expected
and you should not be concerned.
Taking this medicine
• Swallow your tablets whole.
• Do not chew or crush them as this can affect the way your medicine works.
• Your tablets can be taken at any time of day, during or after meals. Choose a time that is
convenient and take your tablet at this time each day.
How much Slocinx XL to take
• The usual dose is one tablet each day.

efficacy have not yet been established.
