How much of the regular dose should elderly patients take when prescribed Haldol?

When considering the dosage of Haldol (haloperidol) for elderly patients, it is important to recognize that older adults are often more sensitive to medications and may experience increased side effects. Therefore, it is standard practice to start with a lower dose, typically half the regular amount, to minimize the risk of adverse effects.

Older individuals often have altered pharmacokinetics, including changes in absorption, distribution, metabolism, and excretion of drugs. As a result, medications may remain in their systems longer, leading to heightened effects or toxicity. Specifically for antipsychotics like Haldol, there is a risk of extrapyramidal symptoms, sedation, and other complications which can be more pronounced in the elderly population. By prescribing half the regular dose, healthcare providers can better manage these risks, allowing for careful monitoring and adjustment of the dosage as needed based on the patient’s response.

This careful approach ensures safety and efficacy in treatment, aligning with best practices in geriatric pharmacotherapy.
