URODOXA Tablet Ref.[51209] Active ingredients: Doxazosin

URODOXA is not recommended for the treatment of heart failure caused by mechanical obstruction, for example aortic or mitral valve stenosis, pulmonary embolism, and restrictive pericardial disease. It should be used with caution is patients with angina pectoris. Treatment with URODOXA should be introduced with caution due to the risk of sudden collapse after the initial dose.

Extra caution is necessary in patients with hepatic or renal impairment and in the elderly. There is no experience with the use of URODOXA in children.

Patients undergoing cataract surgery: Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients on or previously treated with alpha1 blockers. This variant of small pupil syndrome is characterised by the combination of a flaccid iris that billows in response to intraoperative irrigation currents, progressive intraoperative miosis despite preoperative dilation with standard mydriatic medicines, and potential prolapse of the iris toward the phacoemulsification incisions. The patient’s surgeon should be prepared for possible modifications to their surgical technique, such as the utilisation of iris hooks, iris dilator rings, or viscoelastic substances. This does not appear to be a benefit of stopping alpha1 blocker therapy prior to cataract surgery.

Patients taking PDE-5 Inhibitors: Concomitant administration of URODOXA with a PDE-5 inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension.

Postural hypotension with or without symptoms (e.g. dizziness) may develop within a few hours following administration of URODOXA. However, infrequently, symptomatic postural hypotension has also been reported later than a few hours after dosing. As with other alpha-blockers, there is a potential for syncope, especially after the initial dose or after an increase in dosage strength. Patients should be warned of the possible occurrence of such events and should avoid situations where injury could result should syncope occur. Care should be taken when URODOXA is administered to patients with symptomatic hypotension or patients who have had a hypotensive response to other medications.

URODOXA contains lactose and should not be given to patients with rare hereditary problems or a history of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption.

No adverse medicine interaction has been noted in clinical experience with thiazide diuretics, furosemide, beta-blocking agents, oral hypoglycaemic medicines, antibiotics, uricosuric agents or anticoagulants.

However the hypotensive effects of URODOXA may be enhanced by use with diuretics and other anti-hypertensives, and by alcohol and other medicines that cause hypotension. The risk of first-dose hypotension may be particularly increased in patients receiving beta-blockers or calcium channel blockers.

Concomitant administration of URODOXA with a PDE-5 inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension; therefore, PDE-5 inhibitor therapy should be initiated at the lowest dose in patients taking URODOXA.

The safety of URODOXA in pregnancy or lactation has not yet been established (see “CONTRAINDICATIONS”).

The ability to engage in activities such as driving a motor vehicle or operating machinery may be impaired, especially when initiating therapy. URODOXA may cause drowsiness or dizziness therefore patients affected should not drive or operate machinery.
