Abstract:
Risperidone is an atypical antipsychotic drug, which is used in schizophrenia and also to treat excitation and aggression in patients with delirium. Risperidone has a low risk of haematotoxicity because of its different chemical and pharmacological profile compared to other drugs such as clozapine. Haematological abnormalities have life-threatening complications, especially neutropenia, leucopenia and agranulocytosis, but their effect on erythrocytes in adults is less well known. We highlight the effect of risperidone on erythrocytes and the mechanism that leads to anaemia. To the best of our knowledge, this is the only report of 2 patients showing combinations of mechanisms leading to risperidone-induced anaemia.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
