Imagine this: A friend or family member was prescribed painkillers after an injury. At first, they took the medication exactly as directed. But now, weeks later, they seem different—more distant, frequently refilling prescriptions, and sometimes forgetting things mid-conversation. Could this be normal, or is it a sign of something more serious?

Prescription drug abuse happens when someone misuses medications in ways other than prescribed—taking higher doses, using someone else’s prescription, or taking it for non-medical reasons like relaxation or getting high. This issue affects millions of Americans, with opioids, sedatives, and stimulants being the most commonly abused.

Understanding the early warning signs can mean the difference between early intervention and a downward spiral into addiction. Here are seven critical signs to look out for—and what to do next.

1. Unusual or Dishonest Behavior

When people become addicted, they often start displaying unusual behavior as they try to cover up the fact that the addiction is taking over their lives. They may lie about being sick to get out of work, they may be obsessed with finding new doctors to talk to, or they may even use excuses having to do with their kids to get out of events and activities.

Someone who is honest can become manipulative in response to the drug-seeking and management. But even when they’re not being dishonest, they may become distant or quiet, or simply deny certain behavior.

If you suspect prescription drug abuse, look out for changing patterns and schedules. Fatigue, not coming home at the right time, lack of personal hygiene, problems at work or school and unusually secretive behavior can all be cause for alarm.

2. Seeking Multiple Prescriptions & Doctor Shopping

One of the most common ways people hide prescription drug abuse is by visiting multiple doctors for the same prescription—known as doctor shopping. They might claim lost prescriptions, exaggerate symptoms, or visit different pharmacies to avoid suspicion.

Warning signs of doctor shopping include:

  • Seeing multiple healthcare providers without informing them.
  • Requesting early refills or claiming medication was lost.
  • Insisting on specific high-dose prescriptions.
  • Being reluctant to share medical records.

How to Spot It: If a loved one frequently changes doctors or avoids answering questions about prescriptions, this could be a warning sign of prescription drug misuse.

3. Gender Might be a Risk Factor

It’s worth noting that the rate of prescription drug addiction is rapidly increasing amongst women. One 2017 report from the Office of Women’s Health claims that more men than women use these types of drugs, but actually the rates of misuse are increasing faster for women.

Deaths from prescription opioids amongst women increased by 471% between 1999 and 2015, and the percentage for men is less than half of that at 218%. To this end, while it’s never okay to make concrete assumptions based on gender, it’s important not to assume that addiction only happens to men or people in certain income brackets, for example.

4. The Hidden Costs of Prescription Drug Abuse

Financial changes are a key indicator that something is wrong. This is because the more a person becomes addicted, the more they need to satisfy their high. So, they will likely be purchasing higher volumes of a given rug as time goes on.

As their addiction takes hold, they may start to go to extremes such as stealing from family members and fall behind on payments and bills because their addiction becomes too expensive.

You may also notice that a person suddenly has more money than normal, which could indicate that they are involved in the selling or transport of drugs.

Financial Warning Signs:

  • Unexplained financial problems – Frequent borrowing, missing bill payments.
  • Selling valuables – Pawning jewelry, electronics, or personal items.
  • Job loss or performance issues – Frequent absences, lower productivity, disciplinary actions.

Legal Consequences:

  • DUI or drug possession charges – Prescription drug misuse can result in DUI arrests if driving under the influence.
  • Fraudulent prescriptions – Forging prescriptions or illegally obtaining medication is a criminal offense.
  • Workplace violations – Drug use in professional settings can lead to job termination and legal action.

What to Do: If a loved one is facing financial or legal trouble due to prescription drugs, professional intervention is critical. Early action can prevent irreversible damage.

5. General Personality Changes

Personality changes are a normal part of drug use, but they can be subtle enough that you don’t notice them until an addiction becomes severe. Sometimes they may take the form of mood swings or simply “shutting down” and disengaging. They may be more likely to request privacy, stay out late at night, or withdraw from activities they enjoy.

If you bring up a topic like drug use and they get particularly emotional, this may be a sign that they are ashamed and trying to hide something. In general, if people are consistently emotionally volatile or more withdrawn than usual, this could be a sign that something is wrong.

6. Physical & Behavioral Symptoms 

According to the Mayo Clinic, prescription drugs that are most likely to be abused are opioids (e.g., OxyContin, Vicodin) for pain, anti-anxiety medicine (e.g., Xanax, Valium), and stimulants (e.g., Ritalin, Dexedrine).

Symptoms of sedatives include drowsiness or dizziness, as well as confusion and memory loss. The results of misuse of stimulants over a long period of time include weight loss, insomnia, and restlessness, as well as sometimes-rash behavior.

Opiates can cause a drop in blood pressure, constipation, sweating, confusion, and depression. When any of these types of addictions are combined with others such as illicit drugs or alcohol, symptoms will likely be intensified.

7. Social Withdrawal or Isolation

When people begin to do things like neglecting normal responsibilities, sleeping for long hours, hanging out with new people, or even just isolating themselves for no apparent reason for long periods of time, this can be a sign that something is seriously wrong. Depression, anxiety or paranoia may be present or even exacerbated because of the addiction.

8. Understanding Withdrawal Symptoms

Stopping prescription drug use suddenly can trigger withdrawal symptoms that vary by drug type. These symptoms can be physically painful, emotionally distressing, and, in some cases, life-threatening.

Common Withdrawal Symptoms by Drug Type:

Drug Type Withdrawal Symptoms
Opioids Muscle aches, cold sweats, vomiting, insomnia, depression, intense cravings.
Benzodiazepines Severe anxiety, panic attacks, seizures, hallucinations, heart palpitations.
Stimulants Extreme fatigue, depression, lack of motivation, suicidal thoughts, intense hunger.

How Long Do Withdrawal Symptoms Last?

  • Opioid withdrawal: Peaks in 48-72 hours, lasts up to 7 days.
  • Benzodiazepine withdrawal: Can last weeks to months (requires medical detox).
  • Stimulant withdrawal: Symptoms persist for weeks, with cravings lasting months.

🚨 Important: Sudden withdrawal from benzodiazepines or opioids can be dangerous. Medical detox is strongly recommended to prevent complications.

What should you do?

Prescription drug abuse is a complex issue and can affect anyone, yet many people are likely to be in denial about it simply because it’s legal and therefore may not “seem” like an addiction in the same way heavy drug or alcohol use may be.

But the truth is that people easily can fall into the trap of prescription drug misuse simply because they start out using them to quell pain, anxiety, or even mental illness. Sometimes teens might be more prone to addiction if they feel a lot of pressure to perform socially or academically, and people at high-pressure jobs may use things like stimulants just to “get through a day.”
