The effects of taking Lurasidone?


Hello, doctor! I was hospitalized at the beginning of 2022 and diagnosed with schizophrenia.
I have been steadily taking medication for almost two years now, currently on Lurasidone, a muscle relaxant, and a sleeping pill.
The dosage of Lurasidone is 80 mg.
My previous attending physician mentioned that taking Lurasidone would generally prevent menstruation, but I still had my period for the first year while on the medication.
Now, after nearly two years of taking the medication, my periods have gradually stopped.
I do not have a boyfriend and have not engaged in sexual activity.
Is this a common experience for someone on Lurasidone? I would like to know what other conditions I might experience after taking these medications for an extended period.

Common side effects of Lurasidone include increased prolactin levels, extrapyramidal symptoms, drowsiness, and restlessness.
The increase in prolactin levels may lead to delayed or missed menstrual periods.
These side effects can vary from person to person, and not everyone will experience them.
If side effects occur, it is advisable to discuss with a physician whether to arrange for tests to rule out other physiological factors or consider adjusting the medication.

More Info


Lurasidone, marketed under the brand name Latuda, is an atypical antipsychotic medication primarily used to treat schizophrenia and bipolar disorder. It works by modulating the effects of neurotransmitters in the brain, particularly dopamine and serotonin. While it is effective for managing symptoms of mental health disorders, there are concerns regarding its impact on menstrual cycles and overall health.


Effects on Menstrual Cycle
The relationship between antipsychotic medications like Lurasidone and menstrual cycles is complex and not fully understood. Some studies suggest that antipsychotics can influence hormonal levels, potentially leading to changes in menstrual patterns. For instance, women taking antipsychotics may experience irregular periods, amenorrhea (the absence of menstruation), or changes in menstrual flow. This can be attributed to the medication's effects on the hypothalamic-pituitary-gonadal (HPG) axis, which regulates reproductive hormones.

In your case, you mentioned that you initially had regular menstrual cycles while on Lurasidone, but over time, your periods have become less frequent and eventually stopped. This could be a result of the medication's influence on your hormonal balance. It's important to note that while some women may experience amenorrhea due to antipsychotic medications, others may not. Factors such as age, overall health, stress levels, and lifestyle can also play significant roles in menstrual health.


Mental Health Considerations
From a mental health perspective, the cessation of menstruation can have psychological implications. For some women, changes in menstrual cycles can lead to increased anxiety or stress, particularly if they are concerned about the implications for their reproductive health. Additionally, the psychological effects of managing a mental health condition can compound these feelings. It's crucial to maintain open communication with your healthcare provider about any changes you experience, both physically and emotionally.


Long-term Effects and Considerations
Regarding your concern about the long-term effects of taking Lurasidone and other medications, it is essential to consider both the benefits and potential side effects. While Lurasidone can be effective in managing symptoms of schizophrenia, the long-term use of any antipsychotic medication can lead to side effects, including metabolic changes, weight gain, and hormonal imbalances.
If you are experiencing amenorrhea, it is advisable to discuss this with your healthcare provider. They may recommend monitoring your hormonal levels or considering alternative treatments if the side effects are significant. Additionally, if you have concerns about your reproductive health, a gynecologist can provide further insights and management options.


Conclusion
In summary, Lurasidone can influence menstrual cycles, potentially leading to irregularities or amenorrhea. It's essential to monitor these changes and discuss them with your healthcare provider to ensure that your mental health treatment remains effective while also addressing any concerns related to your menstrual health. Open communication with your healthcare team is vital for managing both your mental health and any side effects from medications. If you have further questions or concerns, do not hesitate to reach out to your doctor for personalized advice and support.
