Is there a risk of recurrence of adverse reactions such as delirium after discontinuation of cycloserine?

Cycloserine (Cycloserine) is an anti-tuberculosis drug commonly used in multi-drug-resistant tuberculosis (MDR-TB) and has a central nervous system stimulating effect. During treatment, some patients may experience adverse reactions to the nervous system such as anxiety, depression, insanity, insomnia or hallucinations, which are closely related to the effect of the drug on central neurotransmitters. These side effects usually subside after the drug is discontinued, but the potential risk of recurrence remains a concern.

Clinical observations show that for most patients, symptoms such as confusion, hallucinations, or mood abnormalities will gradually disappear within days to weeks after cycloserine is discontinued. This is because the plasma concentration of the drug in the body decreases and the state of the nervous system affected by the drug is restored. However, for some patients with underlying mental illness or long-term use of cycloserine, delayed manifestations of psychiatric symptoms may still occur after stopping the drug, especially if the drug is stopped suddenly or the dose is adjusted too quickly.

In order to reduce the risk of delirium again after stopping the drug, clinically it is usually recommended to gradually reduce the dose or stop the drug under the guidance of a doctor, and at the same time provide patients with psychological intervention and necessary auxiliary treatment. For example, for patients with symptoms of anxiety or depression, psychological counseling or short-term symptomatic drug treatment can be combined to help patients make a smooth transition. In addition, family members or caregivers should pay attention to changes in the patient's mental status, detect abnormalities in time, and seek medical intervention.

Generally speaking, most adverse reactions will resolve spontaneously after discontinuation of cycloserine, but there is still a risk of recurrence or delayed psychiatric symptoms in a small number of patients. Reasonable drug withdrawal strategies, gradual dose adjustments, and comprehensive follow-up and psychological support are important measures to reduce the recurrence of adverse reactions in the psychiatric nervous system, thereby ensuring the safety and smooth recovery of patients in MDR-TB treatment.
