What is the maximum recommended dosage of Hydroxychloroquine per day?

The maximum recommended dosage of Hydroxychloroquine for adult patients typically includes a limitation based on either a fixed dose or weight-based calculation. Hydroxychloroquine is commonly prescribed for conditions such as rheumatoid arthritis and systemic lupus erythematosus, and its dosing is carefully considered to balance efficacy and safety.

The correct choice reflects both a weight-based recommendation and a maximum fixed dose, which is crucial because different patients may vary significantly in weight. The option indicates that a dose of Hydroxychloroquine should not exceed 5 mg/kg of body weight in addition to a maximum daily limit of 400 mg. This dual approach ensures that patients do not exceed safe usage guidelines regardless of their body weight, particularly since Hydroxychloroquine can have serious side effects when taken in excessive amounts.

This option accurately captures both aspects of the dosing recommendation, therefore providing the maximum safe dosage to accommodate diverse patient populations while minimizing the risks associated with overdose and toxicity.
