Detection: Spot Fake Medicines, Risky Pharmacies, and Early Drug Problems

Buying meds online or starting a new prescription can feel risky. You don’t need to be an expert to spot clear red flags. Use quick checks before you pay, and watch for simple warning signs once you start taking a drug.

Spotting fake or unsafe medication

Check the pharmacy first. Real pharmacies ask for a prescription for prescription-only drugs, show a physical address and phone number, and use HTTPS on their payment pages. Look for trust badges like LegitScript or NABP verification, but click through to confirm they’re valid links.

Price alone can tell you a lot. If a drug costs way less than the usual market price, that’s a reason to pause. Scammers lure people with low prices.

When the package arrives, inspect it. Compare pill color, shape, and imprint to a reliable pill database. Missing or torn leaflets, faded printing, odd fonts, or mismatched batch numbers are signs of counterfeits. If a QR code is present, scan it to check batch details on the manufacturer’s site.

If something feels off, contact the drug maker directly. Many manufacturers will confirm batch numbers and packaging photos. Don’t keep or use pills you suspect are fake—return them and report the seller to your national medicines agency.

Detecting drug problems early and what to do

Know the common warning signs for serious reactions. Sudden rash, swelling, trouble breathing, or fainting means get emergency care. New severe muscle weakness, tendon pain, or long-lasting joint trouble after antibiotics like ciprofloxacin needs urgent medical review.

Watch for mood changes or suicidal thoughts when starting antidepressants or changing doses. Tell a prescriber right away—these reactions can happen even when drugs like Prozac or bupropion are generally helpful.

Drug-specific issues matter. For example, isotretinoin often causes dry eyes and contact lens trouble—if your lenses start to sting, contact your dermatologist. Metformin users should monitor blood sugar and report severe nausea, breathing changes, or muscle pain. Pregnant people should avoid some antiparasitic drugs unless a doctor specifically recommends them.

Keep a simple side-effect log for new prescriptions: date, dose, and any new symptom. That record makes it easier to spot patterns and talk to your provider. If a problem seems serious or gets worse, stop the medication only if your doctor says so—unless it’s life-threatening, then seek emergency care.
