4.2 Can treatment affect intimacy and relationships?
“The most important point is that treatments are not identical in how they influence sexual functioning.”
Elena:
Families often ask, “Does treatment affect sexuality?” What should they understand?
Dr. Stein:
The most important point is that treatments are not identical in how they influence sexual functioning.
Some antipsychotic medications can increase prolactin, a hormone that plays a role in sexual desire, reproductive physiology, and menstrual cycles. When prolactin rises significantly, it can contribute to reduced libido, changes in sexual response, menstrual irregularities, or breast-related symptoms.
Other antipsychotic options have minimal or no impact on prolactin levels.
Large comparative analyses show that prolactin response varies considerably between treatments and even by dose. So, if a patient experiences changes in intimacy, there may be options.
Elena:
This isn’t something patients simply have to accept?
Dr. Stein:
No. It’s something to discuss. Most treatment-related sexual changes are manageable.
Elena:
Dr. Stein, if changes in intimacy can be related to treatment, how can families or patients recognize when something is happening?
Dr. Stein:
That’s an important question, because these changes are often subtle at first.
Someone might feel less interested in closeness or notice that emotional or physical responses feel different. Many people don’t connect it to treatment. They may think, “Maybe it’s just me… maybe something has changed in the relationship.”
Others begin to avoid intimacy or feel less confident in their relationships without fully understanding why.
These signs are not always immediately linked to treatment. They can easily be misunderstood as emotional distance or relationship difficulties. And that uncertainty can make it harder to bring up.
Elena:
The risk may therefore be misinterpreting the situation?
Dr. Stein:
What matters is not to jump to conclusions, but to stay attentive and open.
A helpful approach is to notice patterns over time rather than focusing on a single moment.
Elena:
And how should this be discussed?
Dr. Stein:
Gently and without pressure.
Simple, open questions can be very effective, such as:
• “Have you noticed any changes in how you feel emotionally or physically?”
• “Do you feel comfortable with how things are in your relationship?”
These questions create space without creating discomfort.
Elena:
The aim is to open a conversation, not to assume that there is a problem.
Dr. Stein:
When changes in intimacy are recognized early and discussed openly:
• misunderstandings can be avoided
• treatment can be reviewed if appropriate
• communication and trust can be supported
Recognizing changes early is not about searching for problems.
It is about protecting communication, trust, and well-being.
