I want to speak about something that is very important but often ignored: medication interaction. Medication interaction happens when a person is taking more than one type of medication or substance at the same time, and those substances interact with each other inside the body. When this happens, the effect is not always what we expect. Sometimes the medication becomes too strong, sometimes it becomes weak, and sometimes it creates entirely new problems that were never there before. This issue is especially important when we are supporting people with mental disorders, but it also applies to people with other medical conditions.
Many people living with mental health conditions are not taking just one medication. You may find a person who is taking medication for a mental disorder, and at the same time taking medication for diabetes, blood pressure, epilepsy, pain, or other medical conditions. On top of that, some people also consume alcohol, use hard drugs, or take herbal and traditional remedies.
When all these substances enter the body together, they do not stay separate. They meet. They interact. And when they interact, the outcome can be unpredictable. Some interactions increase side effects. Some reduce the effectiveness of medication. Some create new symptoms that confuse caregivers and even professionals. This is why medication interaction is such a serious issue.
One of the most common causes of medication interaction in mental health is alcohol and drug use. A person may be prescribed medication and told clearly not to drink alcohol or use hard drugs. But in reality, some people still do. Sometimes they sneak alcohol. Sometimes they use drugs in secret. Sometimes they believe a small amount will not matter. But even small amounts can interfere with mental health medication. Alcohol and drugs can block the medication from working properly, or they can intensify side effects such as confusion, aggression, drowsiness, hallucinations, or mood instability. When medication stops working as intended, the person may appear to be “getting worse.” In reality, it is not always the illness worsening—it may be the interaction canceling the treatment.
Many people believe that herbal or traditional remedies are safe because they are “natural.” But natural does not always mean harmless. Herbal remedies can interact with prescribed medication just like alcohol and drugs do. Some herbs speed up how the body breaks down medication, making it ineffective. Others slow it down, causing the medication to build up to dangerous levels in the body. This becomes especially risky when caregivers or family members do not know that the person is taking these remedies. What looks like a sudden change in behavior may actually be the result of an unseen interaction.
When medication interaction happens, several problems can arise. The medication may stop working, leading to relapse or worsening symptoms. Side effects may increase, making the person uncomfortable or distressed. Unexpected reactions may occur, creating confusion and crisis. Caregivers may feel overwhelmed, thinking the situation is out of control. When treatment fails because of interaction, the situation often becomes chaotic. And that chaos can easily be misunderstood as “bad behavior” or “noncompliance,” when in reality the medication is being undermined.
If you are supporting someone with a mental health condition, it is important to be aware of medication interaction. This does not mean controlling the person. It does not mean forcing decisions. It means creating awareness. You talk with the person. You share information. You help them understand how substances affect their medication. You do not lecture. You do not command. You do not shame. Instead, you help the person see the connection between what they take and how they feel. When a person understands that alcohol, drugs, or certain remedies can cancel their treatment or cause harm, they are more likely to make informed choices.
This issue does not apply only to mental health medication. Even people without mental disorders are often warned not to mix certain medications with alcohol, milk, or other substances. The difference is that in mental health, the consequences can be more visible, more disruptive, and more misunderstood. That is why awareness is so important. Medication interaction is real. It is powerful. And it is often invisible until damage is done. Supporting people with mental disorders requires understanding not only the condition, but also how treatment works—and how easily it can be disrupted. When medication interacts with alcohol, drugs, or herbal remedies, the treatment may fail. And when treatment fails, chaos follows.
