1. What Hypovase is and what it is used for
Hypovase is one of a group of medicines called alpha-blockers.
It is usually used to treat high blood pressure (hypertension).
It may also be used to treat heart failure, painful cold fingers (Raynaud’s Disease) or mild enlargement of the prostate gland (prostatic hyperplasia) in men.
In patients with high blood pressure (hypertension) Hypovase works by relaxing blood vessels so that blood passes through them more easily. It can be used alone or in combination with other drugs used to treat hypertension.
In patients with heart failure, Hypovase works by relaxing the main blood vessels of the heart, allowing the heart to pump blood more easily. Hypovase is usually used in heart failure when other drugs are either no longer working or have not worked at all.
In patients with Raynaud’s Disease the treatment relaxes blood vessels in the hands, so blood can reach the fingers more easily. This helps to prevent coldness and stiffness.
In patients with enlargement of the prostate gland the treatment is taken to treat poor and/or frequent passing of urine. This is common in patients with enlargement of the prostate gland.
The treatment works by relaxing muscle around the bladder and prostate gland so urine is passed more easily.
You should ask your doctor if you are unsure why you have been given Hypovase.
2. Before you take Hypovase
Do not take Hypovase if you:
• are allergic (hypersensitive) to prazosin, or to any similar drugs (known as quinazoline drugs) or any of the other ingredients listed in section 6. This may have caused itching, reddening of the skin or difficulty in breathing.
• are under 12 years of age.
Take special care with Hypovase
Medicines are not always suitable for
everyone. Your doctor needs to know before
you take Hypovase if any of the following apply
to you:
• you have heart failure because of another heart condition, e.g. heart valve disease, or a recent heart attack. If you have heart failure, Hypovase can gradually become less helpful over several months. If this happens you may notice swelling of your legs or ankles due to retention of fluid. This is called ‘oedema’. If you develop oedema or weight gain tell your doctor as your doctor may need to change the dose of Hypovase or other medicines you are taking.
• you have ever fainted after passing urine.
• you have liver or kidney disease.
• you are undergoing eye surgery because of a cataract (cloudiness of the lens). This is because Hypovase may cause complications during the surgery which can be managed if your specialist is prepared in advance.
Please inform your eye specialist before the operation that you are using or have previously used Hypovase.
Remember to tell your doctor that you are taking Hypovase if you have any tests, such as a urine test, as Hypovase may affect the result.
Taking other medicines
Some medicines can affect the way Hypovase works. If you are taking any of the following medicines tell your doctor before you start the treatment:
• calcium antagonists, ACE inhibitors or beta-blockers which are usually given to treat angina and/or high blood pressure.
• medicines for erectile dysfunction (impotence).
Some patients who take Hypovase 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 Hypovase. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of Hypovase before you start drugs for erectile dysfunction.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Taking Hypovase with food and drink
Hypovase can be taken before or after food and drinks.
Pregnancy and Breast-feeding
If you are pregnant, planning to get pregnant or are breastfeeding, tell your doctor before you take Hypovase.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Hypovase may cause dizziness, drowsiness or weakness. If you experience these symptoms, do not drive or use any tools or machinery.
3. How to take Hypovase
Always take Hypovase exactly as you doctor has told you. You should check with your doctor or pharmacist if you are not sure. Hypovase tablets are to be taken by mouth.
Sometimes Hypovase can make you feel lightheaded or weak particularly when you first take it. This can happen when standing up and can occasionally cause fainting. If the treatment makes you feel light-headed or weak; lie down until you feel better. Get up slowly when you feel better. If you are concerned, tell your doctor.
Hypovase is usually started at the lowest possible dose and gradually increased, depending on how you respond to treatment. Do not change the dose or stop taking the tablets without first checking with your doctor. Make sure you get a new prescription before your tablets run out.
High blood pressure (hypertension)
The recommended starting dose is one 0.5 mg tablet, two or three times a day for 3 to 7 days with the starting dose taken in the evening.
The dose is usually then increased to a 1 mg tablet taken two or three times a day for a further 3 to 7 days. Your doctor may then advise you to gradually increase the dose further (up to a maximum of 20 mg daily) depending on how your blood pressure has responded to treatment.
Heart failure
The recommended starting dose is one 0.5 mg tablet taken two, three or four times a day.
Your doctor may then advise you to increase the dose further (up to a maximum of 20 mg daily) depending on how you have responded to treatment.
Raynaud’s disease
The recommended starting dose is one 0.5 mg tablet, twice a day for 3 to 7 days.
Your doctor may then advise you to increase the dose further (up to 2 mg twice a day) depending on how you have responded to treatment.

If you take more Hypovase than you should

Always take the labelled medicine package with you, whether there is any Hypovase left or not.
