Warnings and Precautions

  • Who should avoid taking Chlorthalidone?

    Don't take Chlorthalidone if you're allergic to it or its ingredients. Serious allergic reactions, which cause rash, hives, or swelling that makes breathing difficult, require immediate medical help.

    Chlorthalidone can interact with other medications, increasing the risk of side effects. Combining it with other blood pressure medications can lead to very low blood pressure. Nonsteroidal anti-inflammatory drugs (NSAIDs), which are pain relievers, can reduce Chlorthalidone's effectiveness. Lithium, which is used for mood disorders, can have increased levels in the blood when taken with Chlorthalidone, leading to toxicity. Always inform your doctor about all medications you are taking to avoid potential interactions and ensure safe treatment.
