Medication Consultation / Blurred Vision
Hello, I was recently prescribed Deanxit by my family medicine physician due to suspected autonomic nervous system dysfunction.
I took the medication for about 8 weeks.
While my original symptoms were mild and stable, I experienced numerous side effects, including increased palpitations and difficulty sleeping.
During this time, I also had blurred vision.
I gradually reduced the dosage and stopped the medication over the last two weeks.
It has now been a week since I stopped taking the medication, and I still have blurred vision.
How long might it take for my vision to recover? Thank you, doctor.

Dear Ms.
Mila,
The medication "De An Xu" consists of two active ingredients: Flupentixol, an antipsychotic, and Melitracen, an antidepressant.
The half-life of Flupentixol after administration is approximately 35 hours, while Melitracen has a half-life of about 19 hours.
Therefore, if you have stopped taking the medication for a week, these drugs should have been metabolized and eliminated from your system.
Theoretically, you should not be experiencing any residual side effects such as blurred vision.
If you are still experiencing blurred vision, it is advisable to discuss this with your physician to evaluate whether there are other ophthalmic issues.
Thank you.
Sincerely,
Dr.

More Info
Blurred vision after medication can be a concerning side effect, and understanding the timeline for recovery is crucial for patients experiencing this issue. In your case, you were prescribed Deanxit, which contains Flupentixol and Melitracen, for approximately eight weeks. While the medication was intended to help with your symptoms, it appears that you experienced several side effects, including increased heart palpitations, difficulty sleeping, and blurred vision.
Firstly, it is important to note that both Flupentixol and Melitracen have different half-lives, which can affect how long they remain in your system after discontinuation. Flupentixol has a half-life of about 35 hours, while Melitracen has a half-life of approximately 19 hours. Given that you have been off the medication for a week, it is likely that the majority of these drugs have been metabolized and eliminated from your body. Therefore, the persistence of blurred vision may not be directly related to the medication itself at this point.
Blurred vision can arise from various causes, and it is essential to consider other potential factors that may be contributing to your symptoms. For instance, if you were experiencing autonomic nervous system dysregulation, this could lead to visual disturbances. Additionally, stress and anxiety, which may have prompted the initial prescription of Deanxit, can also manifest as visual symptoms.
In terms of recovery, the timeline for blurred vision to resolve can vary significantly from person to person. Some individuals may notice improvement within a few days after stopping the medication, while others may take weeks or even months to fully recover. Factors that can influence recovery include the duration of medication use, individual sensitivity to the drug, and any underlying health conditions that may affect vision.
If your blurred vision persists beyond a week after discontinuation, it is advisable to consult with your healthcare provider. They can perform a thorough evaluation to rule out any other ocular issues or complications that may be contributing to your symptoms. An eye examination can help determine if there are any underlying conditions, such as refractive errors, dry eye syndrome, or other ocular pathologies that need to be addressed.
In summary, while it is reasonable to expect some improvement in blurred vision after stopping Deanxit, the exact timeline for recovery can vary. It is essential to monitor your symptoms and seek medical advice if they persist or worsen. Your healthcare provider can guide you through the recovery process and help identify any additional treatments or interventions that may be necessary to restore your vision to its optimal state.
