What Are Co-Occurring Disorders

Key Takeaways

  • Prescription medications can be safe and effective when used as directed, but misuse can increase the risk of side effects, drug interactions, dependence, addiction, and overdose.
  • Commonly misused prescription drugs include opioids, benzodiazepines, stimulants, and sleep medications, especially when taken in higher doses or mixed with other substances.
  • Treatment may include medical detox, residential care, extended support, Community IOP, mental health services, family education, aftercare, and relapse-prevention planning.

 

Prescription drugs are indispensable in modern medicine, offering effective treatment options for various ailments and improving patients’ lives. When used correctly, they can help manage pain, treat infections, support mental health, control chronic conditions, and improve quality of life.

These medications, available only with a prescription from a healthcare professional, are rigorously tested, diverse in type, and serve purposes ranging from disease management to symptom relief. But “prescribed” does not always mean risk-free. Prescription medications can still cause side effects, interact with other drugs, lead to dependence, or become dangerous when taken in a way other than directed.

Prescription medications can play an important role in treating medical conditions such as infections, chronic illness, mental health disorders, pain, and other symptoms. However, they can also carry risks when they are misused or taken outside of medical guidance. Prescription drug misuse may include taking a higher dose than prescribed, using medication more often than directed, taking someone else’s prescription, mixing medications without a doctor’s approval, or using a medication to feel relaxed, energized, numb, or high. Knowing these risks can help prevent dependence, addiction, overdose, and other serious health problems.

At Midwest Recovery Centers, we help people who are struggling with prescription drug misuse or addiction find the support they need to move forward. Through structured treatment, peer support, relapse prevention planning, and long-term recovery resources, clients can begin to rebuild stability and develop healthier ways to manage life without misusing prescription medications.

“Prescription medications can play an important role in treating medical and mental health conditions, but misuse can increase the risk of dependence, addiction, overdose, and serious health complications. Early recognition of problematic use and access to professional treatment can help individuals regain control and reduce the long-term impact of prescription drug misuse.”

The Dangers of Prescription Drugs

Misusing or abusing any legal or illegal drug can have life-threatening implications. You could have unwanted side effects even if you use a prescribed medication precisely as directed.

Besides unwanted side effects, risks of prescription drugs may include drug interactions, allergic reactions, the development of drug resistance, and the possibility of dependence or addiction.

  • Side effects – These can range from mild and manageable to severe and potentially life-threatening, which is why it’s critical to understand the risks and immediately report concerns to your doctor. While side effects like nausea, constipation, and dry mouth can be common, according to Medical News Today, reactions such as suicidal thoughts and abnormal heart rhythm can be extremely dangerous. For safety, tell your doctor about any unwanted side effects, even if they seem minor.

Even symptoms that seem minor can become more serious if they continue, worsen, or appear after a dosage change.

  • Drug interactions – Prescription drugs can interact with other medications, certain foods or drinks, and existing medical conditions. These interactions can change how a medication works, how the body processes it, or how strong its effects become. In some cases, they may reduce the medication’s benefit or increase the risk of serious side effects.

To lower these risks, tell your healthcare provider about everything you take, including prescription medications, over-the-counter products, vitamins, herbal supplements, sleep aids, pain relievers, and medications prescribed by other doctors. This is especially important with opioids, since combining them with benzodiazepines, alcohol, or other substances that slow the central nervous system can increase the risk of a life-threatening overdose.

  • Allergic reactions – Serious reactions to prescription drugs can range from mild skin rashes to severe anaphylaxis, highlighting the importance of identifying and addressing potential allergies before starting a new medication. Warning signs may include swelling, trouble breathing, hives, dizziness, or a sudden rash after taking a medication.
  • Drug resistance – This is the ability of bacteria or viruses to adapt and survive despite taking medications once effective in eliminating or controlling them. Drug resistance can render certain medications ineffective in treating infections or diseases, limiting treatment options and potentially leading to more difficult-to-treat or untreatable conditions. This is one reason antibiotics and antiviral medications should be taken exactly as directed and never shared with others.
  • Addiction – Prescription medications can be helpful when used as directed, but some still carry a risk of addiction. Certain drugs can lead to physical or psychological dependence, causing cravings, withdrawal symptoms, or a growing urge to keep using them even when they are causing harm. This can happen gradually, especially when someone begins using a medication to cope with stress, sleep problems, emotional pain, or cravings instead of the original medical reason it was prescribed.

To reduce the risk, take prescription medications exactly as directed, pay attention to signs of dependence, and talk to your doctor before changing your dose or stopping use.

  • Overdose – Taking higher doses or combining medications beyond the recommended limits can lead to toxic levels in the body, resulting in severe health consequences, including organ damage, respiratory depression, coma, and even death. Overdose risk is higher when a person takes medication more often than prescribed, uses multiple sedating substances, crushes or snorts pills, or mixes prescription drugs with alcohol or illicit drugs.

Common Types of Prescription Drugs That Are Misused

Prescription drug misuse can involve many types of medication, but some categories carry a higher risk of dependence, addiction, or overdose. Knowing which medications are more commonly misused can help people recognize warning signs earlier and use prescriptions more safely.

“Prescription drug misuse can occur when medications are taken differently than prescribed, used without a prescription, or combined with other substances. Misuse of opioids, benzodiazepines, stimulants, and sleep medications can lead to dependence, addiction, and overdose, making professional treatment and ongoing recovery support essential for long-term recovery.”

Long-Term Effects of Prescription Drugs

Prolonged or excessive use of certain medications can lead to cumulative health risks, dependency, tolerance, organ damage, or other unforeseen complications. The long-term effects of prescription drugs depend on the type of medication, dose, duration of use, personal health history, and whether the drug is being taken as prescribed or misused.

Long-term drug use may contribute to the following:

  • Severe damage to the liver or kidneys.
  • Hormonal imbalance.
  • Impaired physiological function of the cardiovascular, gastrointestinal, or nervous systems.
  • Development of chronic diseases such as metabolic disorders, cardiovascular disease, or osteoporosis.
  • Weakened immune system, increasing susceptibility to acute and chronic conditions.

Long-term use may also lead to tolerance, meaning the same dose no longer produces the same effect. When tolerance develops, some people feel tempted to take more medication than prescribed, which can increase the risk of dependence, withdrawal, and overdose.

Using prescription drugs long-term can also significantly affect your mental health. Some medications directly affect brain chemistry or neurotransmitter levels, leading to mood, cognition, or behavior changes. Certain drugs can cause side effects such as depression, anxiety, or sleep disturbances.

Furthermore, the chronic nature of certain conditions requiring long-term medication use can also affect mental health, leading to emotional challenges or psychological distress. Regular monitoring and open communication with healthcare providers are essential to address and manage these potential mental health effects.

Signs of Prescription Drug Misuse or Addiction

Prescription drug misuse is not always obvious at first. A person may begin by taking medication for a legitimate medical reason and slowly develop a pattern that becomes harder to control. Families may notice changes before the person is ready to admit there is a problem.

Possible signs of prescription drug misuse may include:

  • Taking more medication than prescribed
  • Running out of medication early
  • Visiting multiple doctors to get prescriptions
  • Using someone else’s medication
  • Mixing medication with alcohol or other drugs
  • Taking medication to relax, sleep, focus, numb emotions, or feel high
  • Mood swings, irritability, anxiety, or depression
  • Drowsiness, confusion, memory problems, or poor coordination
  • Changes in sleep, appetite, work, school, or relationships
  • Withdrawal symptoms when trying to cut back

A person does not need to hit “rock bottom” before getting help. If prescription drug use feels difficult to control or is causing problems in daily life, it may be time to talk with a treatment professional.

Why Prescription Drug Misuse Can Be Hard to Recognize

Prescription drug misuse can be difficult to spot because it often begins with a legitimate medical need. Someone may first take medication for pain, anxiety, sleep, ADHD, or another health concern, then slowly start using it in ways that fall outside the original instructions. This can make the problem feel less obvious than misuse involving illegal substances.

A person may also believe the medication is safer because it came from a doctor. While prescription drugs can be safe and effective when used correctly, they can still carry serious risks when doses increase, use continues longer than intended, or the medication becomes a way to cope with stress, emotions, or daily pressure.

Families may notice subtle changes first, such as mood swings, secrecy, sleep changes, running out of medication early, or becoming defensive when prescription use is mentioned. These early warning signs matter because getting help sooner can reduce the risk of dependence, addiction, overdose, and long-term health consequences.

The Difference Between Dependence, Tolerance, and Addiction

Dependence, tolerance, and addiction are related, but they are not the same thing. Knowing the difference can help people better recognize what may be happening and when professional support may be needed.

This is why it is important to talk with a healthcare provider before stopping or changing certain prescriptions. Some medications require a careful taper to reduce withdrawal symptoms and protect physical and mental health.

What Makes Prescription Drugs Dangerous?

Improper use or abuse of medications, inadequate understanding of risks and side effects, and the impact of pharmaceutical companies on prescribing practices all play a role in determining the safety and long-term impact of prescription drug use. Understanding these contributing factors is vital to promoting responsible medication use and minimizing potential harm.

  • Misuse of prescription drugs, such as taking higher doses, combining medications without medical guidance, or using them for non-medical purposes, can lead to serious health risks, including addiction, overdose, and organ damage.
  • Insufficient knowledge about the potential risks and side effects of prescription drugs can cause unintended consequences. Patients may fail to recognize warning signs or disclose relevant information to healthcare providers, leading to adverse reactions or complications.
  • Pharmaceutical companies shape prescribing practices through marketing strategies, influence physicians’ prescribing decisions, and emphasize the benefits of their products. Self-serving approaches can impact the volume and type of prescriptions, potentially exposing patients to medications that may carry unnecessary risks or lack sufficient evidence of long-term safety.

Addressing these factors requires collaboration among healthcare professionals, patients, regulatory bodies, and pharmaceutical companies. Enhancing patient education, promoting responsible prescribing practices, and ensuring transparency and accountability in the pharmaceutical industry can contribute to the safer and more effective use of prescription drugs.

Prescription Drug Abuse Treatment and Services at Midwest Recovery Centers

Midwest Recovery Centers offers several behavioral health services for people struggling with prescription drug misuse, substance use disorders, mental health concerns, or co-occurring conditions. Care is built around structure, accountability, clinical support, and the level of treatment each person needs.

Substance Use Disorder Treatment

For substance use treatment, Midwest Recovery Centers offers a phased care model that supports clients from stabilization into longer-term recovery.

The substance use track may include:

  • Medical Detox & Residential Care: The first 30 days include supervised detox and residential treatment for alcohol or drug use. Medication-assisted treatment is offered during detox when clinically appropriate. Clients may also participate in evidence-based therapies such as CBT, ACT, and DBT, along with holistic activities and experiential group therapy.
  • Phase 1 Extended Care: After detox and residential care, clients may move into Phase 1, which lasts about 60 days and includes housing as part of the program. This level provides continued structure, accountability, and recovery support.
  • Phase 2 Extended Care: Phase 2 can continue for up to 9 months, depending on clinical need. Housing is also part of this phase, giving clients ongoing support as they build recovery skills in daily life.

Midwest Recovery Centers treats many types of substance use concerns, including alcohol, heroin, methamphetamine, cocaine, marijuana, prescription drugs, and other substances.

Community IOP and Medical Oversight

Midwest Recovery Centers offers :

  • Community IOP for substance use disorders 
  • Community IOP for mental health disorders 

These programs are designed for people who need structured support while continuing to live at home or in another supportive setting.

Medical oversight may include:

  • Psychiatric evaluations
  • Medication management
  • Long-acting injectables, when appropriate
  • TMS, or Transcranial Magnetic Stimulation
  • PGX genetic testing at all levels of care
  • Telemedicine support

Mental Health and Co-Occurring Disorders

Midwest Recovery Centers also provides treatment for people whose primary concern is mental health. The residential mental health program is a 45-day program designed for primary mental health disorders, with treatment tracks shaped around each client’s needs.

Outpatient mental health services are also available and do not have to follow residential treatment. Some clients may begin with outpatient support based on their symptoms, goals, and clinical recommendations.

For clients facing both addiction and a mental health diagnosis, Midwest Recovery Centers uses an integrated care model that addresses both concerns together. This is important because untreated anxiety, depression, trauma, or mood symptoms can increase the risk of returning to substance use.

Family Program and Aftercare

Midwest Recovery Centers includes family programming because addiction and mental health challenges often affect the entire support system. Family services provide education, counseling, and guidance for loved ones as they learn healthier ways to support recovery.

Virtual Substance Use Disorder Family Programming is held Thursdays from 6:30–8:00 PM CST and follows a 4-part monthly rotation:

  • 1st Thursday: Addiction education, causes, family dynamics, and what to expect at Midwest Recovery Centers
  • 2nd Thursday: Enabling, healthy support, grief, and codependency
  • 3rd Thursday: Healthy boundaries before, during, and after treatment
  • 4th Thursday: Family recovery, self-care, detaching with love, and changing family roles

The Virtual Family Program for Mental Health is held on the 3rd Thursday of the month at 8:00 PM CST and offers support, connection, and coping tools for families of individuals living with mental illness.

In-person family education is also available through “Supporting Their Next Steps: An Aftercare Info Session for Families,” held on the 1st Wednesday of the month at 7:00 PM at the Main Outpatient Campus: 13340 Holmes Rd, Kansas City, MO 64145.

Aftercare services help clients continue building stability after treatment, especially during the first year of recovery. Support may include individualized aftercare planning, counselor check-ins, individual and group therapy, relapse-prevention planning, and connection to sober community support.

Treatment Outcomes at Midwest Recovery Centers

Midwest Recovery Centers tracks progress through regular check-ins focused on cravings, sleep, mood, substance-use patterns, and risk of return to use. Tools such as the Brief Addiction Monitor, or BAM, may be used, along with mental health symptom scales, so progress can be measured clearly over time.

20242025 outcomes data showed:

  • 100% reduction in alcohol use, drug use, marijuana use, sedative use, and overall substance use while clients were in care
  • 64% decrease in risk of use
  • About 55% reduction in cravings
  • Sleep problems improved by as much as 81%
  • Mood concerns decreased by 75%
  • Satisfaction with recovery improved by about 80%
  • Spirituality increased by about 26%

For mental health clients, PHQ-9 results showed depression symptoms dropping by 87%, while GAD-7 results showed anxiety symptoms improving by as much as 78%. PTSD symptoms measured through PCL-5 follow-ups also trended downward substantially over time.

These outcomes do not promise the same results for everyone, but they show what can be possible when treatment is structured, consistent, and tailored to each patient’s unique needs.
