Phenazopyridine can cause several side effects, although not everyone experiences them. The most common include orange-red discoloration of urine, which is harmless but noticeable. You may also experience mild stomach upset, such as nausea. Less frequently, headaches and dizziness occur. In rare instances, skin reactions, such as rash or itching, may develop.
More Serious Side Effects
While uncommon, more serious side effects warrant immediate medical attention. These include difficulty breathing, swelling of the face or throat (angioedema), and jaundice (yellowing of skin or eyes). If you experience any of these, stop taking phenazopyridine and seek medical help immediately. Also, inform your doctor if you notice changes in your blood count or have liver or kidney problems.
Remember to carefully read the medication information provided with your prescription. Your doctor or pharmacist can answer any questions you have about side effects and potential interactions with other medications. Always discuss any concerns you have before starting or continuing to take phenazopyridine.
