Discontinuation of medication?

How long does it take for the psychiatric medications Lufulon (Flupentixol) and Kangyou (Sertraline) to be eliminated from the body after discontinuation? I have recently reduced my medication with my doctor's permission and have been off the medication for three weeks.
I often experience sudden dizziness and tingling sensations, but they resolve quickly.
Is this normal?

Hello, Joy: When discontinuing "Rifampicin" after long-term use, the complete elimination of the drug may be slow, taking from several days to weeks, during which some drug effects may still be present.
Common withdrawal symptoms observed clinically include: tension, anxiety, difficulty concentrating, insomnia, palpitations, sweating, etc.
"Antidepressants," as they are serotonin reuptake inhibitors, may cause transient "serotonin syndrome" in the early stages of withdrawal (within hours to several days), which includes symptoms such as arrhythmias, hypertension, muscle weakness, elevated body temperature, and disorientation.
However, these symptoms are quite rare in clinical practice.
Common withdrawal symptoms include: restlessness, anxiety, dizziness, unsteady gait, headaches, excessive sweating, insomnia, nausea, tremors, fatigue, and lightheadedness.
The symptoms you mentioned are likely common withdrawal symptoms.
If they do not interfere with your daily activities or routines and remain within a tolerable range without worsening, there is no need for excessive concern.
Feel free to reach out, and wishing you peace!

More Info

When it comes to psychiatric medications, the duration it takes for these drugs to clear from the body can vary significantly based on several factors, including the specific medication, dosage, duration of use, individual metabolism, and overall health of the patient.
Most psychiatric medications have a specific half-life, which is the time it takes for half of the drug to be eliminated from the body. For instance, medications like SSRIs (Selective Serotonin Reuptake Inhibitors) can have half-lives ranging from about 24 hours to several days. This means that after stopping the medication, it may take several days to weeks for the drug to be mostly cleared from your system. However, some medications, especially those with longer half-lives, may take weeks or even months to be completely eliminated.

In your case, you mentioned that you have been off the medication for three weeks and are experiencing symptoms like sudden dizziness and tingling sensations. These symptoms can be part of withdrawal or discontinuation syndrome, which can occur when stopping certain psychiatric medications, particularly if they have been taken for a long time or at high doses. Withdrawal symptoms can vary widely among individuals and may include dizziness, anxiety, mood swings, and physical sensations like tingling or numbness.

It is essential to understand that while some level of discomfort or unusual sensations can be expected during the withdrawal phase, if these symptoms persist or worsen, it is crucial to consult with your healthcare provider. They can assess your symptoms in the context of your overall health and medication history and may recommend strategies to alleviate these symptoms. This could include a gradual tapering of the medication rather than an abrupt stop, which can help minimize withdrawal effects.

Moreover, the timeline for recovery from withdrawal symptoms can vary. Some individuals may start feeling better within a few weeks, while others may take longer. Factors such as the type of medication, how long it was taken, and individual differences in metabolism and brain chemistry all play a role in how quickly one can recover.

In summary, while it is common to experience some symptoms after stopping psychiatric medications, the duration and intensity of these symptoms can vary. It is always best to maintain open communication with your healthcare provider during this process to ensure that you receive the appropriate support and guidance tailored to your specific situation. They can help you navigate through this period and make any necessary adjustments to your treatment plan.
