Seek medical attention right away if you experience pain during urination, blood in the urine, unusual bleeding or bruising, or seizures after taking this medication. These are serious adverse reactions and require immediate medical attention.
As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medication/ supplements you are currently taking before starting treatment with acetazolamide. Additionally, acetazolamide is in the same class of drugs as sulfa, so if you have a sulfa allergy, be sure to alert your clinician. Acetazolamide can interact with other forms of medication and substances, causing potentially serious side effects.
In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.
