Menstruation and Antipsychotic Medications: What You Need to Know - Obstetrics and Gynecology

When it comes to the relationship between menstruation and antipsychotic medications, particularly in the context of long-term use of medications like Seroquel (quetiapine), there are several important factors to consider.
Antipsychotic medications, especially those that are dopamine antagonists, can have a significant impact on the hormonal balance in the body. One of the hormones affected is prolactin, which is produced by the pituitary gland. Elevated levels of prolactin, a condition known as hyperprolactinemia, can lead to various reproductive issues, including amenorrhea (the absence of menstruation). This is particularly relevant for individuals who are on antipsychotic medications for extended periods.

In your case, having not had a menstrual period since starting Seroquel and now being on a reduced dose raises a few considerations. First, it is essential to determine whether the absence of menstruation is solely due to the medication or if there are other underlying factors at play. Stress, significant weight changes, and other medical conditions can also contribute to menstrual irregularities.

Here are some steps you might consider:
1. Consult Your Psychiatrist: Since you have been on Seroquel for a long time and are currently reducing the dosage, it is crucial to discuss your menstrual issues with your psychiatrist. They can evaluate whether the medication is the likely cause and may suggest monitoring your hormone levels, particularly prolactin.

2. Visit a Gynecologist: It may also be beneficial to consult a gynecologist. They can perform a thorough evaluation to rule out other potential causes of amenorrhea, such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances. They may recommend tests such as blood work or imaging studies.

3. Consider Hormonal Treatments: If it is determined that your amenorrhea is related to elevated prolactin levels due to Seroquel, your healthcare provider may discuss options for managing this condition. This could include adjusting your medication or considering other treatments to help regulate your menstrual cycle.

4. Monitor Symptoms: Keep track of any other symptoms you may be experiencing, such as changes in mood, weight fluctuations, or physical health issues. This information can be valuable for your healthcare providers in determining the best course of action.

5. Lifestyle Factors: Consider lifestyle factors that could be influencing your menstrual cycle. Stress management, a balanced diet, regular exercise, and adequate sleep can all play a role in hormonal balance and overall well-being.

In summary, while it is not uncommon for antipsychotic medications to affect menstrual cycles, it is essential to approach this issue holistically. Engaging with both your psychiatrist and a gynecologist will provide a comprehensive view of your health and help you make informed decisions regarding your treatment and menstrual health. Remember, open communication with your healthcare providers is key to finding the right balance in your treatment plan.
