Additionally, those who are allergic to the dyes included in this medication should also be careful. This medication can cause a range of side effects, from mild dizziness to severe fainting. Symptoms such as dizziness or a rapid heartbeat may occur, especially when starting the medication or suddenly increasing the dosage, so caution is advised. During use, various symptoms may appear, including headaches, drowsiness, indigestion, nasal congestion, and urinary issues, and if an allergic reaction occurs, the medication should be stopped immediately, and a doctor consulted. As this medication has a blood pressure-lowering effect, caution is necessary when driving or operating dangerous machinery. Additionally, since dizziness may occur when standing up suddenly, it is best to move slowly. When taking this medication for the treatment of prostatic hyperplasia, prostate cancer status must be confirmed, and individuals scheduled for cataract surgery should inform their doctor about this medication before the surgery. While there are generally no major issues when taken with various other medications, caution is needed when taken with antihypertensive drugs, as it may cause blood pressure to drop too low. Women who are pregnant or may become pregnant should consult a doctor before taking this medication, as use may not be safe, and breastfeeding women should avoid taking it or stop breastfeeding. The safety and efficacy have not been confirmed in children, so its use is not recommended. In the elderly, there is a risk of excessively low blood pressure leading to stroke; therefore, it is important to start with a low dose and use cautiously. In case of overdose, severe hypotension may occur, and it is essential to visit a medical institution immediately for appropriate treatment, as dialysis is ineffective. This medication should be kept out of reach of children, and it is safer not to transfer it to other containers.
