Never stop taking montelukast without first consulting your doctor or asthma nurse. Stopping abruptly can worsen symptoms and may even lead to adverse reactions. This applies even if your asthma symptoms seem to have improved.
Reasons to Consider Stopping Montelukast (Under Doctor's Supervision):
-
Unacceptable Side Effects: If you experience serious side effects, such as neuropsychiatric reactions (affecting sleep, behavior, or mood), your doctor may advise you to stop taking montelukast immediately. These side effects can occur during treatment and even after you've stopped. The FDA advises seeking medical attention if such side effects develop. (FDA, 2022).
-
Lack of Effectiveness: If your symptoms do not improve after using montelukast, or if they worsen, it is crucial to seek medical advice. Your doctor may adjust your dosage, change your medication, or recommend stopping montelukast entirely. ([Reference 1](Reference information from the provided text: "Do not stop taking these medicines and do not reduce the dose, even if your asthma seems better, unless you or your child are told to do so by your doctor**. Talk to your doctor or get medical care right away if: Your or your child's symptoms do not improve after using this medicine or if they become worse.")).
-
Doctor's Recommendation: Ultimately, your doctor will determine when and if you should stop taking montelukast. They will consider your individual circumstances, medical history, response to the medication, and any potential side effects. (NHS, Gov.uk)
Important Note: While some sources suggest no withdrawal concerns are expected (HealthMatch), it is crucial to follow your doctor's guidance to ensure a safe and effective transition off the medication. Abrupt cessation may result in symptom rebound or worsen existing neuropsychiatric conditions. (Psychiatrist.com)
