8 Medication Myths Most People Believe — And What's Actually True

We've all grown up with certain "facts" about medications and health that feel totally obvious. Take an antibiotic for that cold. Grapefruit only matters with one or two meds. A higher dose means faster results.

Except... some of those aren't quite right. And a few of them could actually get you into trouble.

Here are eight of the most common medication myths we hear — and what the real story is.

Myth #1: "Antibiotics Will Help Me Get Over This Cold Faster"

When you're miserable and just want to feel better, it's tempting to ask your doctor for antibiotics. And plenty of people do.

What's actually true: Antibiotics fight bacteria — not viruses. Colds, the flu, and most sore throats are caused by viruses, which means antibiotics have zero effect on them. Taking an antibiotic when you don't need one doesn't help you recover faster. It does, however, kill off beneficial gut bacteria, can cause side effects, and contributes to antibiotic resistance — a serious and growing public health problem.

If your doctor doesn't prescribe an antibiotic, that's often good news, not a brush-off. It means what you have is viral and needs time, rest, and fluids — not a prescription.

Myth #2: "Everyone Should Take a Daily Low-Dose Aspirin for Their Heart"

For decades, daily aspirin was widely recommended as a simple way to reduce heart attack risk. Your parents probably follow this advice. Maybe you do too.

What's actually true: Guidelines have changed significantly. The U.S. Preventive Services Task Force now recommends against starting daily low-dose aspirin for heart attack prevention in adults 60 and older who have never had a heart attack or stroke. The risk of internal bleeding — which increases with age — now outweighs the benefit for most people in this group.

For people who have already had a heart attack or stroke, daily aspirin may still be appropriate — but that's a conversation to have with your doctor, not a decision to make on your own. If you're currently taking daily aspirin, don't stop without checking with your provider first.

Myth #3: "Grapefruit Only Affects One or Two Obscure Medications"

Most people have heard a vague warning about grapefruit and certain medications. They assume it applies to something rare they'll never take.

What's actually true: Grapefruit — and grapefruit juice — interacts with more than 85 medications, including many common ones. It contains compounds that block an enzyme your body uses to break down certain drugs. The result: medication builds up to higher levels in your bloodstream than intended, which can lead to serious side effects.

The list includes widely used drugs like certain cholesterol medications (statins), blood pressure medications, some anti-anxiety medications, and certain antihistamines. The effect can last more than 24 hours after you drink the juice — so spacing it out doesn't necessarily solve the problem. If you take any regular prescriptions, ask your pharmacist whether grapefruit is on your "avoid" list.

Myth #4: "Antidepressants Are Addictive"

Fear of addiction is one of the most common reasons people avoid antidepressants — or stop taking them sooner than they should.

What's actually true: Antidepressants are not addictive. They do not cause cravings, euphoria, or the compulsive drug-seeking behavior associated with addiction. You won't need more and more of them to feel the same effect over time.

What people sometimes confuse with addiction is discontinuation syndrome — uncomfortable symptoms that can occur if you stop an antidepressant abruptly rather than tapering off gradually under medical supervision. That's a real thing, but it's not addiction. It's why you should always work with your prescriber when adjusting or stopping these medications, rather than quitting cold turkey. This myth prevents a lot of people from getting help they genuinely need.

Myth #5: "Wait Until the Pain Gets Bad Before Taking Anything"

It sounds responsible — why medicate when you can tough it out? But this approach often backfires.

What's actually true: For many types of pain, staying ahead of it is more effective than chasing it. Pain signals in your body can amplify the longer they go unaddressed, making pain harder to control once it's reached a high level. This is why post-surgical instructions often say to take pain medication on a schedule — even if you feel okay — rather than waiting until you're in significant discomfort. This also applies to conditions like migraines, where early treatment with the right medication can stop an episode from escalating. If your provider has prescribed a pain medication with dosing instructions, follow them as directed rather than rationing doses out of caution.

Myth #6: "It's Fine to Share a Prescription With Someone Who Has the Same Symptoms"

Your friend has what looks like the same infection you had last month. You have leftover medication. It seems generous, even helpful.

What's actually true: Sharing prescription medications is both dangerous and illegal. Prescriptions are written for a specific person, at a specific dose, based on their full medical history, other medications, allergies, and the exact nature of their condition. What's right for you can be genuinely harmful for someone else. Even the same type of infection in two people may require different antibiotics or different doses.

Beyond safety, it's also a legal issue. Prescription medications are controlled for good reason. The safest and most helpful thing you can do for a sick friend is encourage them to call their doctor or pharmacist.

Myth #7: "Taking More of a Medication Will Make It Work Faster or Better"

If one pill helps, two should help more — right?

What's actually true: Medication doses are carefully calculated to deliver therapeutic benefit while minimizing risk. With most drugs, doubling the dose doesn't double the effect — it usually just doubles your exposure to potential side effects, and in some cases, it can be dangerous or even life-threatening.

This applies to OTC medications too, not just prescriptions. Exceeding the recommended dose of acetaminophen, for example, can cause serious liver damage even when taken without ill intent. If a medication doesn't seem to be working at the recommended dose, talk to your pharmacist or prescriber — not to the pill bottle.

Myth #8: "Your Pharmacist Is Just There to Fill Prescriptions"

This one's personal to us.

What's actually true: Pharmacists are among the most accessible healthcare professionals available to you. No appointment needed. No copay for a conversation. And the training goes far beyond counting pills — pharmacists complete years of clinical education and are specialists in how medications work, interact, and affect the body.

Your pharmacist can review your complete medication list for interactions, recommend the right OTC product for your specific situation, answer questions your doctor didn't have time to address, flag concerns before they become problems, and provide services like immunizations and medication therapy management.

At Good Day Pharmacy, that accessibility is something we take seriously. We're independent, which means we have the time and the relationships to actually talk through your questions — not just hand you a bag and move on.

The Real Takeaway

A little knowledge goes a long way when it comes to your health. Some of these myths seem harmless — but acting on the wrong information at the wrong time can have real consequences.

When in doubt, ask. That's what we're here for.
