Precautions

This medication should not be administered to certain patients. For example, it should not be taken by those who are allergic to this medication or similar drugs, or by children under 12 years of age. Patients with severely impaired liver or kidney function, orthostatic hypotension, heart disease, cerebrovascular disorders, diabetes, and other specific conditions should use this medication with caution. This medication contains a dye called Yellow No. 5, so patients allergic to this ingredient should take precautions. Taking this medication can cause a range of side effects from mild dizziness to severe fainting. Caution is particularly needed when starting treatment or suddenly increasing the dosage, as blood pressure may drop sharply and cause fainting. Psychological symptoms such as depression or anxiety may occur, as well as headaches, drowsiness, nausea, abdominal pain, shortness of breath, and urinary issues. Additionally, while this medication helps alleviate symptoms of benign prostatic hyperplasia, symptoms can be similar to those of prostate cancer, so it is crucial to check for cancer before treatment. When taken with antihypertensive medications, the blood pressure-lowering effect may become stronger, so it is advisable to consult with healthcare professionals. Women who are pregnant or breastfeeding should avoid this medication due to safety concerns unless absolutely necessary and should consult a physician before use. Particular attention is required for children and the elderly, and for the elderly, it is recommended to start with a lower dose and monitor the condition before administration. In case of overdose, blood pressure may drop sharply, so one should visit a medical facility immediately for appropriate treatment. This medication should be stored out of reach of children and should not be transferred to other containers for safety. Finally, there are some animal study results regarding the long-term use of this medication, but it is unclear whether the same effects occur in humans.
