In a world of noise, it’s hard to know who you should trust — especially when it comes to medication.

Between word-of-mouth advice, the internet, and confusing labels, it's not always clear what’s true and what’s not.

But when it comes to your health, getting accurate information about your medications is essential.

To help you separate fact from fiction, here are seven common medication myths — and, more importantly, the truth behind them:
‍

Myth #1: Antibiotics Cure All Infections

Fact: Antibiotics are powerful medications, but they only work against bacterial infections, not viral ones like the common cold, flu, or COVID-19.

Despite their effectiveness in treating bacterial infections like strep throat or urinary tract infections, antibiotics have no impact on viruses.

And, even worse, taking antibiotics when they’re not needed can contribute to antibiotic resistance.

Antibiotic resistance happens when bacteria evolve and develop the ability to withstand the effects of medications designed to kill them, making infections harder to treat in the future.

Every year in the U.S., over 2.8 million people are affected by antibiotic-resistant infections, and more than 35,000 people die as a result.

To avoid antibiotic resistance and get the treatment you need without the added risk, make sure to follow instructions from your pharmacist.

Myth #2: You Can Stop Taking Medication When You Feel Better

Fact: Just because you feel better doesn’t mean your body has fully healed.

While you might feel better after a few days on medication, it doesn’t mean the underlying infection has been fully treated. In this case, patience is the name of the game.

For many conditions — especially bacterial infections — taking the full course of antibiotics (as prescribed) is crucial.

Stopping your medication too early can allow bacteria to survive and lead to a relapse, or as mentioned above, antibiotic resistance.

To avoid this, prioritize finishing your prescribed medication — even if you start feeling better before the course is complete.

If you're unsure about how long to take your medication, check with your doctor or pharmacist.

Myth #3: Natural Remedies Are Always Safe

Fact: Just because something is natural doesn’t mean it’s safe or effective.

For example, St. John’s Wort, a common herbal supplement for depression, can interfere with medications like antidepressants (SSRIs), birth control, and blood thinners like warfarin.

Nearly 20% of Americans use dietary supplements alongside prescription medications, yet only 38% of those disclose this to their healthcare providers, according to the NIH.

If you find yourself mixing medications, reconsider.

Mixing meds can be dangerous, as some supplements may enhance or diminish the effects of what you’ve been prescribed.

Before adding any new supplement to your routine, always consult with your pharmacist to ensure there won’t be harmful drug interactions.

Myth #4: Generic Medications Aren’t as Effective as Name-Brands

Fact: Generic medications have the same active ingredients, strength, dosage form, and route of administration as their brand-name counterparts.

In addition to similar chemical makeup, they must meet FDA standards for quality, safety, and effectiveness.

In fact, the FDA requires that generic drugs have an absorption rate of 80% to 125% of the brand-name drug, ensuring that they work in the same way.

One of the biggest benefits of generics is cost savings.

On average, generic medications are 80-85% less expensive than their brand-name versions, according to the FTC.

For example, the brand-name drug Lipitor — which is used to treat high cholesterol — can cost around $150 for a month’s supply, while the generic (atorvastatin) typically costs under $15.

Switching to a generic medication, then, can make a big difference in reducing your healthcare costs without sacrificing effectiveness.

Myth #5: All Medications Have to Be Taken at the Same Time

Fact: While some medications need to be taken at specific times to be effective, others are more flexible.

For example, statins (like atorvastatin) are typically taken at night because cholesterol production in the liver is higher while you sleep.

On the other hand, medications for blood pressure like ACE inhibitors (like lisinopril) can be taken any time of day, as long as it’s consistent.

Always follow the directions provided by your healthcare provider or pharmacist.

And if you’re unsure about the best time to take your medication, don’t hesitate to ask your pharmacist for advice.
‍

Myth #6: If You Miss a Dose, Just Double Up on the Next One

Fact: Taking two doses at once can lead to dangerous side effects or an overdose.

For example, doubling up on medications like blood pressure drugs (like lisinopril or amlodipine) can lead to dangerously low blood pressure — causing dizziness, fainting, or even more serious health problems.

If you miss a dose, stick to the instructions on your prescription label.

In most cases, you should take the missed dose as soon as you remember unless it’s nearly time for your next dose — in that case, just skip the missed dose and get back to your routine as normal.
