Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to take ALFAPROST
If you are going to undergo cataract surgery, please inform your doctor before the operation if you are taking or have taken ALFAPROST previously. This is because ALFAPROST may cause complications during the operation, which can be taken into account and controlled by your ophthalmologist if they have been informed beforehand.
Children and adolescents
The use of ALFAPROST is not indicated in children, as the safety and efficacy of this medication in children have not been determined.
Elderly people
Caution is necessary when administering the first dose, increasing the dose, or starting the dose after treatment interruption, due to the high incidence of postural hypotension (low blood pressure when standing up) in this age group.
Taking ALFAPROST with other medications
If you are taking an antihypertensive (to lower high blood pressure), consult your doctor to adjust the dose.
Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication.
Some patients who are receiving an alpha-blocker for the treatment of high blood pressure or prostatic hyperplasia may experience dizziness or fainting, which can be caused by a decrease in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking medications for erectile dysfunction (impotence) with alpha-blockers like ALFAPROST. To reduce the likelihood of these symptoms, you should be receiving your daily dose of alpha-blocker regularly before starting treatment for erectile dysfunction.
Taking ALFAPROST with food, drinks, and alcohol
This medication can be taken with or without food.

The safety of ALFAPROST during pregnancy has not been established. ALFAPROST should only be used during pregnancy when the doctor considers that the potential benefits justify the risk to the fetus.
If you are breastfeeding, it is not recommended to take ALFAPROST. It is not known whether terazosin is excreted in breast milk.
