Warnings and precautions

Consult your doctor or pharmacist before starting to take Unibenestan:

- If you are taking other medications such as ketoconazole and itraconazole (antibiotics).

- Before starting treatment with Unibenestan, your doctor may perform some tests to rule out the presence of other diseases that may cause the same symptoms as benign prostatic hyperplasia. Before treatment and at regular intervals, a rectal examination and blood tests may be performed.

- If you are to undergo any surgical intervention, you should inform the anesthesiologist, prior to the intervention, that you are taking Unibenestan (see section “Use of Unibenestan with other medications”).

- If you have previously been treated with a similar medication to Unibenestan, inform your doctor.

- Taking Unibenestan may cause you to feel dizziness, sweating, or fatigue (due to a decrease in blood pressure when standing up) in the hours following the medication intake (see section “Possible side effects”), especially in patients who also take medications for high blood pressure or nitrates (for the treatment of heart disease). If you notice these symptoms, you should remain lying down until you feel better. This is more common at the beginning of treatment and generally does not prevent its continuation.Inform your doctor if you have ever experienced a strong drop in blood pressure when treated for high blood pressure with other medications.

- If you have or have had heart disease, as this medication may increase the risk of hypotension (decrease in blood pressure) when administered concurrently with nitrates (heart disease medication) (see section “Possible side effects”). If angina pectoris reappears or worsens, treatment with alfuzosin should be interrupted. Inform your doctor if you have any heart-related problems related to the QT interval.

- If you have any liver or kidney disease, your doctor may modify the dose to be taken.

• If you are an elderly patient, as there may be a higher risk of hypotension and other adverse effects related to this.

- If you are to undergo eye surgery for cataracts, please inform your doctor before the operation if you are taking or have taken Unibenestan previously. This is because Unibenestan may cause complications during the operation, which can be taken into account and controlled by your ophthalmologist if you have been informed in advance.

Alfuzosin, like other medications in the same family, may cause priapism (persistent and painful erection of the penis). If this occurs, go immediately to an emergency service for treatment.

Consult your doctor even if any of the circumstances mentioned above have occurred at any time.
