The recommended dose and dosing schedule of topotecan varies according to body size and the results of blood tests carried out before your treatment. It is injected into a vein through a specially prepared site on your skin. The appropriate dose is usually injected over 30 minutes, once daily for 5 consecutive days followed by 16 days without medication. This cycle is then repeated at least 3 more times.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. Your doctor may choose a schedule different from the one listed here.
Very careful handling of this medication is required. It is always given under the supervision of a doctor in a hospital or similar setting with access to sterile equipment for preparation.
