Alfuzosin Hydrochloride 2.5mg Tablets
⚠ This medicine appears to have been discontinued
The electronic medicines compendium (emc) no longer publishes a Summary of Product Characteristics for this product, which usually means it is no longer marketed in the UK. The patient leaflet below is kept for reference, but the product may not be available.
If you were prescribed this medicine, other products containing Alfuzosin hydrochloride may still be available. Do not stop your treatment — ask your pharmacist or GP what to use instead.
What it is and what it is used for
for What alfuzosin is The name of your medicine is Alfuzosin Hydrochloride 2.5mg Tablets (called alfuzosin throughout this leaflet). This belongs to a group of medicines, alpha-blockers. Alfuzosin can be used to treat the symptoms of Benign Prostatic Hyperplasia. This is when the prostate gland enlarges (hyperplasia), but the growth is not cancerous (it is benign). It can cause problems in passing water (urine). This happens mainly in older men.
- The prostate gland lies underneath the bladder. It surrounds the urethra. This is the tube that takes your water to the outside of the body.
- If the prostate gets bigger, it presses on the urethra making it smaller. This makes it difficult to pass water.
- Your tablets work by relaxing the prostate gland muscle. This allows the urethra to get bigger and so makes it easier to pass water. In a few patients with benign prostatic hyperplasia, the prostate gland gets so big that it stops the flow of urine completely. This is called Acute Urinary Retention.
- This is very painful and you may need a short stay in hospital.
- A thin, flexible tube (catheter) is passed into the bladder. This drains the water and relieves the pain.
- During this time, alfuzosin may be used to help the water to flow again. This has only been shown to help in men aged over 65.
reading
Do not take alfuzosin and tell your doctor if you:
- are allergic (hypersensitive) to alfuzosin hydrochloride or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
- are taking other alpha-blockers. See section below on 'Other Medicines and Alfuzosin '.
- have something called orthostatic hypotension. This is a drop in blood pressure which usually happens when you stand up. It can make you feel dizzy, light-headed or faint when you stand or sit up quickly.
- have liver problems
- You are taking Ritonavir alone or in combination with ombitasvir/paritaprevir, lopinavir, nirmatrelvir. See section "Other medicines and Alfuzosin". If you are not sure if any of these apply to you do not take Alfusozin and talk to your doctor. Take special care and check with your doctor or pharmacist before taking alfuzosin if:
- You have chest pain (angina)
- You have a condition where your kidneys are hardly working at all
- You have heart problems, or if your heart suddenly stopped pumping efficiently (acute cardiac failure)
- You have hereditary problems with the way your heart beats (congenital QTc prolongation)
- You are over 65. This is due to the increased risk of developing hypotension and related adverse reactions in elderly patients
- You ever get painful erections of the penis, unrelated to sexual activity that will not go away, before or during treatment. If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking alfuzosin. Other medicines and Alfuzosin Tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because alfuzosin can affect the way some other medicines work. Also some medicines can affect the way alfuzosin works. Do not take this medicine, and tell your doctor, if you are taking:
- Other alpha-blockers such as doxazosin, indoramin, prazosin, terazosin, tamsulosin, or phenoxybenzamine.
- Ritonavir by itself, or in combination with ombitasvir/paritaprevir, or lopinavir and nirmatrelvir. Using these medicines together can make the amount of alfuzosin in your blood too high because your liver won't be able to clear it properly. Tell your doctor or pharmacist before taking your medicine if:
- In the past you have had a large fall in blood pressure while taking an alpha-blocker (this could include previous use of alfuzosin). See paragraph immediately above for examples of other alphablockers.
- You are taking a medicine for high blood pressure, as you may get dizzy, weak or start sweating within a few hours of taking this medicine. If this happens, lie down until the symptoms have completely gone. Tell your doctor as he or she may decide to change the dose of your medicine.
- You are taking medicines such as glyceryl trinitrate for chest pain (angina)
- You are taking medicines for fungal infections (such as itraconazole).
- You are taking medicines for HIV (such as ritonavir).
- You are taking medicines for bacterial infections (such as clarithromycin, telithromycin).
- You are taking medicines for treatment of depression (such as nefazodone).
- You are taking ketoconazole tablets (used to treat Cushing's syndrome – when the body produces an excess of cortisol). Operations and tests while taking alfuzosin
- If you are being treated for high blood pressure, your doctor should measure your blood pressure regularly, especially at the start of treatment.
- If you are going to have an operation on the eye because of cataract (cloudiness of the eye), tell your eye specialist you are using or have used alfuzosin in the past. This is because alfuzosin may cause complications during your operation. This can be managed if your eye specialist knows before carrying out the operation.
- If you are going to have an operation that needs a general anaesthetic, tell your doctor you are taking alfuzosin before the operation. Your doctor may decide to stop you having alfuzosin 24 hours before the operation. This is because it can be dangerous as it can lower your blood pressure. Alfuzosin with food and drink You may feel dizzy and weak whilst taking alfuzosin. If this happens do not drink any alcohol. Driving and using machines You may feel dizzy and weak while taking alfuzosin. If this happens do not drive or operate any tools or machines. Important information about the ingredients of alfuzosin hydrochloride Alfuzosin contains lactose If you have been told by your doctor that you have an intolerance to some sugars contact your doctor before taking this medicinal product. This medicine contains less than 1mmol sodium (23mg) per dose, that is to say essentially 'sodium free'.

⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
4.1. Therapeutic indications
Alfuzosin is indicated in the treatment of the functional symptoms of benign prostatic hypertrophy.
4.2. Posology and method of administration
Alfuzosin hydrochloride 2.5mg tablets should be swallowed whole. The first dose should be given just before bedtime.
Adults
The usual dose is one tablet three times daily. The dose may be increased to a maximum of 4 tablets (10mg) per day depending on the clinical response.
Elderly and treated hypertensive patients
As a routine precaution when prescribing alfuzosin to elderly patients (aged over 65 years) and the treated hypertensive patient, the initial dose should be 1 tablet in the morning and 1 tablet in the evening.
Renal insufficiency
In patients with renal insufficiency, as a precaution, it is recommended that the dosing be started at alfuzosin hydrochloride 2.5mg tablets twice daily adjusted according to clinical response.
Hepatic insufficiency
In patients with mild to moderate hepatic insufficiency, it is recommended that therapy should commence with a single dose of alfuzosin hydrochloride 2.5mg tablets/day to be increased to alfuzosin hydrochloride 2.5mg Tablets twice daily according to clinical response.
Paediatric population
Efficacy of alfuzosin has not been demonstrated in children aged 2 to 16 years (see section 5.1). Therefore, alfuzosin is not indicated for use in the paediatric population.
4.3. Contraindications
• Hypersensitivity to the active substance or to any of the excipients (see section 6.1).
• History of orthostatic hypotension.
• Combination with other alpha-1 receptor blockers.
• Concomitant administration with ritonavir alone or in combination with ombitasvir/paritaprevir, lopinavir and nirmatrelvir (see Section 4.5).
• Severe hepatic insufficiency.
4.4. Special warnings and precautions for use
.
As with all alpha-1 blockers in some subjects, in particular patients receiving antihypertensive medications or nitrates, postural hypotension with or without symptoms (dizziness, fatigue, sweating) may develop within a few hours following administration. In such cases, the patient should lie down until the symptoms have completely disappeared. These effects are transient, occur at the beginning of treatment and do not usually prevent the continuation of treatment.
Pronounced drop in blood pressure has been reported in post-marketing surveillance in patients with pre-existing risk factors (such as underlying cardiac diseases and/or concomitant treatment with anti-hypertensive medication, see section 4.8). The risk of developing hypotension and related adverse reactions may be greater in elderly patients. The patient should be warned of the possible occurrence of such events.
As with all alpha1-receptor blockers, alfuzosin should be used with caution in patients with acute cardiac failure.
Care should be taken when Alfuzosin is administered to patients who have had a pronounced hypotensive response to another alpha-1-blocker.
Treatment should be initiated gradually in patients with hypersensitivity to alpha-1-blockers. Alfuzosin should be administered carefully to patients being treated with antihypertensive medication or nitrates (see section 4.5). Blood pressure should be monitored regularly, especially at the beginning of treatment.
Patients with congenital QTc prolongation, with a known history of acquired QTc prolongation or who are taking drugs known to increase the QTc interval should be evaluated before and during the administration of alfuzosin.
Concomitant use of alfuzosin and potent CYP3A4 inhibitors (such as itraconazole, ketoconazole, protease inhibitors, clarithromycin, telithromycin and nefazodone) should be avoided (see section 4.5). Alfuzosin should not be used concomitantly with CYP3A4 inhibitors that are known to increase the QTc interval (e.g. itraconazole and clarithromycin) and a temporary interruption of alfuzosin treatment is recommended if treatment with such medicinal products is initiated.
Prolonged erections and priapism have been reported with alpha-1 blockers including alfuzosin in post marketing experience. If priapism is not treated immediately, it could result in penile tissue damage and permanent loss of potency, therefore the patient should seek immediate medical assistance (see section 4.8).
Precautions
In coronary patients, the specific treatment for coronary insufficiency should be continued. If angina pectoris reappears or worsens alfuzosin hydrochloride 2.5 mg tablets should be discontinued.
The 'Intraoperative Floppy Iris Syndrome' (IFIS, a variant of small pupil syndrome) has been observed during cataract surgery in some patients on or previously treated with alpha1-blockers.Although the risk of this event with alfuzosin appears very low, ophthalmic surgeons should be informed in advance of cataract surgery of current or past use of alpha-1-blockers, as IFIS may lead to increased procedural complications. The ophthalmologists should be prepared for possible modifications to their surgical technique
Excipients
Alfuzosin hydrochloride 2.5 mg tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
This medicine contains less than 1mmol sodium (23mg) per tablet, that is to say essentially 'sodium free'
4.5. Interaction with other medicinal products and other forms of interaction
Combinations contraindicated:
• Alpha-1-receptor blockers (see section 4.3)
Concomitant use not recommended:
• Potent CYP3A4 inhibitors such as itraconazole, ketoconazole, protease inhibitors(e.g. ritonavir), clarithromycin, telithromycin and nefazodone since alfuzosin blood levels may be increased (see section 4.4).
Combinations to be taken into account:
• Antihypertensive drugs (see section 4.4)
• Nitrates (see section 4.4)
The administration of general anaesthetics to patients receiving alfuzosin hydrochloride 2.5mg tablets could cause profound hypotension. It is recommended that alfuzosin hydrochloride 2.5mg tablets be withdrawn 24 hours before surgery.
Other forms of interaction
No pharmacodynamic or pharmacokinetic interaction has been observed in healthy volunteers between alfuzosin and the following drugs: warfarin, digoxin, hydrochlorothiazide and atenolol.
4.6. Pregnancy and lactation
Due to the type of indication this section is not applicable.
4.7. Effects on ability to drive and use machines
There are no data available on the effect on driving vehicles. Adverse reactions such as vertigo, dizziness and asthenia may occur essentially at the beginning of treatment. This has to be taken into account when driving vehicles and operating machinery.
4.8. Undesirable effects
Classification of expected frequencies:
Very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
4.9. Overdose
In case of overdosage, the patient should be hospitalised, kept in the supine position, and conventional treatment of hypotension should take place.
In case of significant hypotension, the appropriate corrective treatment may be a vasoconstrictor that acts directly on vascular muscle fibres.
Alfuzosin is not dialysable because of its high degree of protein binding.
