Do you also feel discomfort such as burning, pain, or difficulty urinating? Or do you often have difficulty urinating and then have difficulty passing urine? In such a situation, when we go to see a doctor, there may be a special medicine among the medicines that the doctor gives us. When you drink it, your urine turns a dark orange color, sometimes even red. Some people get scared after seeing this. That medicine, that is, Phenazopyridine, is what we are going to learn about in this article today.
What exactly is Phenazopyridine?
Simply put, it is a painkiller that reduces inflammation, pain, and discomfort in the urinary tract. It works by numbing the inner lining of the urinary tract, temporarily reducing the pain and inflammation we feel. It works like a doctor injecting a numbing medicine into your gums before extracting a tooth.
But here's something we all need to remember. Phenazopyridine is not an antibiotic. That is, this medicine will not cure a urinary tract infection (UTI). It only controls the symptoms caused by the infection. To cure the infection, you need to take the antibiotic medicine prescribed by your doctor for the full duration.
Things to tell your doctor before taking this medicine
Before your doctor prescribes this medication for you, it is very important to inform him of some facts about your health condition.
- Kidney disease: If you have any kidney-related condition, be sure to tell your doctor.
- G6PD deficiency: You should also tell your doctor if you have a deficiency in an enzyme called G6PD (Glucose-6-phosphate dehydrogenase). This is a hereditary condition that some people have in their blood.
- Allergies: Tell your doctor if you have any allergies to phenazopyridine, any other medicine, food, or dyes used in clothing.
- Pregnancy and breastfeeding: If you are pregnant, trying to become pregnant, or breastfeeding, you should talk to your doctor before taking this medicine.
