Consult your doctor or pharmacist even if any of the above circumstances have occurred to you at any time.
Using Benestan Retard with other medicines
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines (especially medicines for high blood pressure), including those obtained without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.

Medicines that must be used with caution:
Additionally, the administration of general anesthetics to patients treated with Benestan Retard can cause blood pressure instability, so in the event of surgery, you should inform the anesthesiologist that you are taking Benestan Retard.

Pregnancy and breastfeeding
This is not applicable, as the use of this medicine is only in males.
Driving and using machines
You should be aware that the ability to drive vehicles or operate machinery may be impaired by the possibility of side effects such as dizziness and fatigue, especially at the start of treatment. If this is the case, you should avoid driving and operating hazardous machinery.
Benestan Retard contains hydrogenated castor oil

Follow the instructions for administration of this medicine exactly as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.
Remember to take your medicine.
If you think the effect of Benestan Retard is too strong or too weak, tell your doctor or pharmacist.
The recommended dosage is orientative and variable. The establishment of the dosage regimen is left to medical discretion.
The tablet should be swallowed whole. Any other method of administration, such as chewing, crushing, sucking, grinding, or pulverizing, should be avoided, as these actions could lead to inappropriate absorption of the medicine and, therefore, to the rapid appearance of possible adverse reactions.
Adults
1 tablet, twice a day (morning and night), which corresponds to 10 mg of alfuzosin per day.
Elderly patients
As a precaution, it is recommended to start treatment with a dose of 1 tablet at night (5 mg of alfuzosin), which will be increased to 1 tablet twice a day, according to the clinical response, without exceeding 10 mg of alfuzosin per day.
Renal impairment
In patients with mild or moderate renal impairment, as a precaution, it is recommended to start treatment with 1 tablet at night (5 mg of alfuzosin), which will be increased to 1 tablet twice a day, according to the clinical response, without exceeding 10 mg of alfuzosin per day.
In patients with severe renal impairment, it is recommended not to use Benestan Retard. Therefore, your doctor will prescribe a treatment with a lower dose, which will be increased according to the clinical response.
Hepatic impairment
In patients with mild to moderate hepatic impairment (liver disease), it is recommended not to use Benestan Retard. Therefore, your doctor will prescribe a treatment with Benestan 2.5 mg.
In Benestan Retard, the medication is located in the middle of a non-absorbable tablet, specially designed for controlled release of the active substance. When this process is complete, the empty tablet is eliminated from the body through the feces, so it is possible that you will find the tablet coating in your stool.
Use in children
The efficacy of alfuzosin has not been demonstrated in children from 2 to 16 years old. Therefore, alfuzosin is not indicated for use in children.
