Managing Side Effects of Lofepramine: When to Stop Medication? - Psychiatry

Share to:

If the side effects of Lofepramine are intolerable, can I stop taking the medication on my own?


I have been undergoing treatment for depression for many years, and my previous primary medication was Venlafaxine.
On the 17th, my doctor switched my medication to Lofepramine due to my autonomic nervous system disorder.
After taking it for one day, I found the side effects unbearable (dizziness, weakness, insomnia, vomiting, constipation, night sweats, palpitations).
I called the pharmacist at the clinic, who advised that since it was my first time taking the medication, I could stop it and wait for my next appointment.
However, I continued taking it for another two days, and the side effects became increasingly severe.
Therefore, I stopped taking it on the 20th.
I would like to know how long the side effects of the medication will last, as they have significantly impacted my daily life, and I am unable to seek medical attention.
Thank you.

Hello, the half-life of Lofepramine is approximately 11 hours, and the side effects of the medication typically resolve within two days.
The situation you described should still consider the possibility of withdrawal symptoms or drug interactions.
It is recommended that you consult with a physician for further discussion.
Best wishes, Peng Li-Yun, Department of Child and Adolescent Psychiatry, Shun An Chia Nan Rehabilitation Hospital.

Managing side effects from medications, especially those used to treat mental health conditions like depression, can be challenging. In your case, you have recently switched from fluoxetine (known as Prozac) to lofepramine (often referred to as Lofepramine or Lofepramine Hydrochloride), and you are experiencing significant side effects such as dizziness, weakness, insomnia, nausea, constipation, night sweats, and palpitations.
First and foremost, it is essential to understand that side effects can vary widely among individuals, and not everyone will experience the same reactions to a medication. Lofepramine is a norepinephrine and dopamine reuptake inhibitor, and while it is generally well-tolerated, some patients may experience adverse effects, particularly when starting the medication or adjusting the dosage.

Given your experience, it is advisable to stop taking the medication, especially since the side effects have become increasingly intolerable. The recommendation from the pharmacist to stop the medication after the first day was appropriate, as it is crucial to listen to your body and prioritize your well-being.
As for how long the side effects will last after discontinuing lofepramine, this can vary. Generally, most side effects from medications like lofepramine should start to diminish within a few days to a week after stopping the medication. However, some individuals may experience lingering effects for a longer period, particularly if they have been on the medication for an extended time or if they have a sensitive system.
In your case, since you took the medication for a total of three days, you might expect the side effects to begin resolving within a few days. However, if you find that the symptoms persist or worsen, it is crucial to seek medical attention. While you mentioned that you cannot visit a healthcare provider immediately, consider reaching out to a mental health professional or your primary care physician via telehealth services if available. They can provide guidance on managing withdrawal symptoms and discuss alternative treatment options that may be better suited for you.

In the meantime, focus on self-care strategies that can help alleviate some of the side effects you are experiencing. For example, staying hydrated, eating a balanced diet, and engaging in light physical activity can help improve your overall well-being. Additionally, practicing relaxation techniques such as deep breathing, meditation, or gentle yoga may help reduce anxiety and improve sleep quality.

Lastly, it is essential to communicate openly with your healthcare provider about your experiences with medications. If you have a history of anxiety or depression, it may take some time to find the right medication or combination of treatments that work for you without causing intolerable side effects. Your mental health is a priority, and there are many options available to help you manage your condition effectively.
In summary, if you have stopped taking lofepramine due to severe side effects, you can expect these effects to diminish within a few days to a week. If symptoms persist, seek medical advice as soon as possible. Remember, managing mental health is a journey, and finding the right treatment plan is crucial for your overall well-being.
