Pack contents and other information

1. What Progandol is and what it is used for

Progandol is a medicine that belongs to a group of medicines called alpha-blockers and is used:

• in the treatment of hypertension (high blood pressure),
• in urinary tract obstruction and symptoms associated with an enlarged prostate (benign prostatic hyperplasia).

Progandol may be used in patients with benign prostatic hyperplasia, regardless of whether they have high or normal blood pressure.

Patients with both conditions may be treated with Progandol as monotherapy.

2. What you need to know before taking Progandol

Treatment with Progandol requires periodic monitoring by your doctor.

Do not take Progandol

• if you are allergic to doxazosin, other quinazolines (e.g., prazosin, terazosin), or any of the other ingredients of this medicine (listed in section 6),
• if you have experienced hypotension (low blood pressure) when taking other medicines for high blood pressure,
• if you have an enlarged prostate together with urinary tract obstruction, chronic urinary infection, or bladder stones,
• if you have low blood pressure.

Warnings and precautions

Talk to your doctor before starting Progandol:

• if you have liver problems, Progandol should be used with caution,
• if you have benign prostatic hyperplasia and are hypotensive,
• if you suffer from acute heart disease (heart condition), such as pulmonary edema or heart failure,
• if you are scheduled for cataract surgery, inform your doctor if you are taking or have previously taken Progandol. This medicine may cause complications during surgery, which your ophthalmologist can manage if informed in advance.

Prolonged and painful erections may occur very rarely. If this happens, consult a doctor urgently.

Before starting treatment with Progandol, your doctor may perform tests to rule out other conditions such as prostate cancer, which may cause the same symptoms as benign prostatic hyperplasia.

Taking Progandol with other medicines

Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines.

Progandol has been administered together with other antihypertensives and other medicines such as non-steroidal anti-inflammatory drugs, antibiotics, oral antidiabetics, gout medications, anticoagulants, digoxin, warfarin, phenytoin, and indomethacin without negative consequences. Doxazosin enhances the effect of other blood pressure-lowering medicines (thiazide diuretics, furosemide, beta-blockers).

Consult your doctor or pharmacist before using Progandol if you are taking any of the following medicines, as they may alter the effect of Progandol:

• Medicines for erectile dysfunction (e.g., sildenafil, tadalafil, vardenafil).
• Medicines that reduce blood pressure.
• Medicines used 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.
