  1. Antibiotics (Germ Killers) Can Eliminate Any Infection!
    This class of drugs, unfortunately, is often misused based on recommendations from non-experts. Antibiotics are only effective against bacterial infections. Bacteria are just one cause of infections; other agents such as viruses, fungi, and parasites can also cause infections. Therefore, antibiotics have no effect on these agents and may only lead to side effects and the destruction of beneficial gut bacteria.
  2. I’m Feeling Better; It’s Time to Stop My Medication!
    The duration of medication use is determined based on large-scale, controlled studies. Stopping a drug earlier than prescribed or suddenly discontinuing it can lead to consequences such as disease relapse, incomplete treatment, future flare-ups, and withdrawal symptoms. Sudden withdrawal symptoms, including restlessness, sweating, depression, hand tremors, and irritability, are seen in medications such as antidepressants, sedatives, and blood pressure drugs. Avoid stopping medications abruptly without consulting your doctor.
  3. If I Take More Medicine Today, I’ll Get Better Faster!
    In addition to determining the treatment duration, studies also precisely establish the optimal dosage for treating or managing each condition. Your doctor prescribes the required dose based on your condition. Taking more than the recommended dose will not speed up recovery and may even intensify side effects. If you notice no improvement, consult your doctor to determine the best course of action.
  4. All Painkillers Are Addictive!
    This belief does not apply to all painkillers. Only specific classes, such as opioids and stimulants, can lead to addiction. Additionally, multiple factors contribute to addiction, varying from person to person and situation to situation. With careful medical supervision and personalized treatment plans, pain can be effectively managed while minimizing addiction risks.
  5. My Mother Took This Medicine and Felt Great, So I’ll Take It Too!
    Each medication is designed for a specific condition, and diagnoses vary from person to person. Only a doctor can properly assess this. Additionally, individual responses to the same medication can differ due to factors such as age, gender, weight, overall health, and concurrent medications. Therefore, avoid self-medicating without consulting your doctor.
  6. I Forgot My Morning Dose, So I’ll Take Two Now!
    Doubling the dose at once can cause significant side effects. Always ask your doctor about what to do if you miss a dose, especially for chronic conditions. Different medications have different guidelines for missed doses. If you’re unsure, sticking to your regular dosing schedule is a safer choice than doubling the dose.
  7. Medication Leaflets Are Useless and a Waste of Money and Paper!
    Drug leaflets contain valuable and essential information that helps ensure proper medication use and answers common questions, such as:

    • Should the medication be taken before or after meals?
    • What foods or drugs might interact with it?
    • Are there important details you forgot to mention to your doctor?
    • How should the medication be stored?
    • Additional explanations you may have missed during discussions with your doctor or pharmacist.
      Keep the leaflet for the entire duration of your treatment.
  8. All Pills Can Be Split in Half!
    Only certain scored tablets can be split, and only with a doctor’s approval. In unscored tablets, the active ingredient may not be evenly distributed, leading to unequal doses. Some pills have special coatings for slow release in the body, and splitting them can compromise their effectiveness. Always consult your doctor before splitting a pill.
  9. All Capsules Can Be Opened and Mixed with Food or Water!
    This is only possible with specific capsules. In some cases, opening a capsule can reduce its effectiveness or increase its side effects. Always consult your doctor before doing so.
  10. I Put All My Medications in a Weekly Pill Organizer!
    Certain medications, such as moisture- and light-sensitive pills, refrigerated drugs, and those that should not be handled without gloves, should not be stored in a pill organizer.
