From sleep aids and cough syrups to constipation pills and memory supplements, some familiar pharmacy products may deliver far less than their advertising promises. Here’s what the science says—and which affordable alternatives may be worth considering.
Walk into almost any pharmacy, and you’ll find shelves packed with products promising fast relief. A syrup to stop coughing. A capsule to improve memory. A pill to help you sleep. Another to get your digestion moving again.
The packaging looks convincing. The claims sound reassuring. And the prices? Sometimes surprisingly high.
But what if some of these popular products aren’t nearly as effective as consumers believe?
Licensed pharmacist Grant Harting attracted attention online after questioning the value of several widely sold medications and supplements. His criticism wasn’t necessarily that every product was dangerous. Instead, he raised a question that deserves more attention:
Are people paying premium prices for products that offer little additional benefit—or, in some cases, lack convincing evidence that they work at all?
It’s an uncomfortable question for an industry built around convenience, branding, and the promise of quick results.
Let’s examine six categories worth questioning, what research actually reveals, and where simple lifestyle measures or traditional herbal remedies may have a role.
1. Popular Sleep Aids: Are You Paying More for an Antihistamine?
Many nighttime sleep products contain diphenhydramine, an older antihistamine that causes drowsiness.
It’s an ingredient found in certain allergy medications and over-the-counter sleep aids, including some ZzzQuil formulations.
While diphenhydramine can make people sleepy, that doesn’t automatically make it a good solution for insomnia.
The American Academy of Sleep Medicine recommends against using diphenhydramine to treat chronic insomnia because the evidence of meaningful benefit is limited.
Potential side effects include:
- Next-day grogginess and reduced alertness
- Dry mouth and constipation
- Dizziness
- Confusion, particularly in older adults
A more natural approach: Chamomile and passionflower have long histories of traditional use in relaxing bedtime routines. Although research hasn’t established them as reliable treatments for chronic insomnia, a warm cup of caffeine-free herbal tea may offer a comforting evening ritual.
Maintaining a consistent sleep schedule, reducing evening caffeine, and keeping the bedroom cool and dark are also sensible first steps.
For persistent insomnia, cognitive behavioral therapy for insomnia (CBT-I) has stronger evidence than most over-the-counter sleep products.
The takeaway: Feeling sedated is not necessarily the same as getting restorative sleep.
2. Colace and Other Stool Softeners: Do They Really Work?
Constipation is uncomfortable, frustrating, and incredibly common.
Millions of people turn to stool softeners, including products containing docusate sodium, the active ingredient in Colace.
But there’s a surprising problem: the clinical evidence supporting docusate is remarkably weak.
Some studies have found little or no advantage over placebo, while research comparing docusate with psyllium fiber has favored psyllium.
This doesn’t mean everyone who takes docusate experiences no benefit. It means the scientific support is less convincing than many consumers might expect.
What may work better?
For uncomplicated constipation, consider increasing fiber gradually through foods such as:
- Prunes, which contain fiber and naturally occurring sorbitol
- Ground flaxseed
- Oats
- Vegetables and legumes
- Psyllium husk, a soluble fiber with evidence supporting its use for constipation
Adequate fluid intake and regular movement also help support bowel function.
Psyllium should always be taken with sufficient water and may not be appropriate for people with swallowing difficulties or suspected bowel obstruction.
If lifestyle changes aren’t enough, polyethylene glycol is another treatment supported by clinical guidelines.
The takeaway: Sometimes the most useful digestive remedy isn’t the most heavily advertised product.
3. Cold and Congestion Medicines: One Common Ingredient Faces Serious Questions
Few things are more frustrating than buying an expensive cold medicine and still struggling to breathe through your nose.
One ingredient in particular has attracted regulatory scrutiny: oral phenylephrine.
It’s commonly found in products marketed for nasal congestion, including certain formulations labeled PE.
In November 2024, the U.S. Food and Drug Administration proposed removing oral phenylephrine from the over-the-counter nasal decongestant monograph after reviewing evidence that it does not effectively relieve nasal congestion.
The agency’s concern was effectiveness, not a newly identified safety problem.
Importantly, this conclusion applies to phenylephrine taken by mouth, not necessarily nasal formulations or other ingredients in combination cold medicines.
What can you try instead?
Several low-cost measures may provide symptom relief:
Saline nasal spray: Helps moisturize irritated nasal passages and clear mucus.
Warm beverages: Ginger tea with lemon or honey can soothe an irritated throat, although it won’t directly cure an infection.
Honey: May reduce nighttime coughing associated with upper respiratory infections in some people. Never give honey to infants younger than 12 months.
A clean humidifier: May improve comfort when indoor air is dry.
Saline nasal rinses should be prepared with distilled, sterile, or previously boiled and cooled water.
Other decongestants, including pseudoephedrine, may be effective but are unsuitable for some people, particularly those with uncontrolled high blood pressure or certain cardiovascular conditions.
The takeaway: Before purchasing cold medicine, examine the active ingredients rather than relying on the promise printed across the front of the box.
4. Expensive Cough Medicines: Is the Relief Worth the Price?
Cough syrups occupy an enormous amount of pharmacy shelf space, yet evidence for several ingredients is mixed.
Guaifenesin, commonly marketed as an expectorant, is intended to make mucus easier to clear.
However, studies have produced inconsistent findings about how much it improves cough symptoms during acute respiratory illnesses.
That doesn’t mean guaifenesin never helps. It means its effects may be more modest or uncertain than the marketing suggests.
For a mild cough associated with a common cold, simple approaches are sometimes sufficient.
Traditional remedies worth considering
Honey and warm water: A soothing combination that may temporarily ease coughing and throat irritation.
Thyme tea: Traditionally used for coughs and respiratory discomfort, although high-quality evidence for ordinary homemade thyme tea remains limited.
Ginger infusion: A warming drink that may soothe the throat and encourage fluid intake.
Avoid drinking essential oils or using concentrated herbal extracts internally without qualified guidance.
A cough accompanied by breathing difficulty, chest pain, coughing blood, or persistent high fever requires medical assessment. A cough lasting more than three weeks should also be evaluated.
The takeaway: Not every cough requires an expensive syrup, but natural remedies should not delay appropriate medical treatment.
5. Memory Supplements: Can a Capsule Really Make Your Brain Sharper?
One of the most profitable promises in wellness marketing is the idea that a daily supplement can dramatically improve memory.
Prevagen, a well-known memory supplement, became the subject of legal action over claims about cognitive benefits.
In 2024, a federal court ordered its marketers to stop using certain unsupported advertising claims following litigation involving the Federal Trade Commission and New York authorities.
The larger issue extends beyond any single brand.
Many products advertised as brain boosters rely on preliminary studies, animal research, or small human trials that don’t establish clinically meaningful improvements.
What about herbal brain support?
Traditional medicine has long used several plants associated with cognitive health.
Bacopa monnieri: Some small clinical trials suggest possible benefits for particular memory measures, but larger, better-designed studies are needed.
Ginkgo biloba: Frequently promoted for memory and circulation, yet convincing evidence of meaningful cognitive improvement in healthy individuals remains limited. It can also interact with medications, including blood thinners.
Lion’s mane mushroom: An interesting area of early research, but human studies remain too limited to support claims that it restores nerve cells or prevents dementia.
The most reliable brain-health habits are considerably less glamorous: regular physical activity, adequate sleep, balanced nutrition, social connection, and management of cardiovascular risk factors.
The takeaway: A supplement advertised as scientifically proven isn’t necessarily supported by strong clinical evidence.
6. Pain Patches and Anti-Inflammatory Gels: More Expensive Doesn’t Always Mean More Effective
Pain relief is another category where brand names, prescription strength, and pricing can create confusion.
Consider topical lidocaine patches.
Prescription-strength patches commonly contain 5% lidocaine, while some over-the-counter alternatives contain 4%.
These products are not necessarily interchangeable: their formulations, approved indications, and evidence differ. Nevertheless, comparing available options with a healthcare professional may reveal a more affordable approach for a particular condition.
Another frequently misunderstood product is topical diclofenac, sold under brands such as Voltaren.
Unlike a product designed for immediate numbing, diclofenac reduces inflammation. Its benefits for conditions such as osteoarthritis may develop over several days of regular use.
That doesn’t make it ineffective. It means expectations matter.
Can plants offer pain relief?
One of the more interesting plant-derived ingredients is capsaicin, the compound responsible for the heat in chili peppers.
Standardized capsaicin creams and patches have evidence supporting their use for certain localized pain conditions, including some neuropathic pain.
However, capsaicin can cause significant burning and skin irritation. Homemade concentrated cayenne preparations are difficult to dose safely and should not be treated as equivalent to regulated products.
Ginger and turmeric have also attracted research interest for inflammation and joint discomfort.
Some studies suggest modest symptom benefits, particularly for osteoarthritis, but supplements vary in quality and may interact with medications.
For mild muscular discomfort, gentle stretching, heat or cold therapy, and appropriate physical activity may provide additional relief.
The takeaway: The best pain treatment depends on the cause, not the strength of the marketing campaign.
The Hidden Problem: When Advertising Becomes More Convincing Than Evidence
There’s an important distinction between a medication that genuinely doesn’t work, a product with limited research, and an effective medicine sold at an unnecessarily high price.
They aren’t the same thing.
Generic medicines can contain the same active ingredients as more expensive branded versions. Some well-established medications offer important benefits despite their relatively low cost.
Likewise, natural doesn’t automatically mean safe, effective, or superior.
Herbs contain biologically active compounds. Some can interfere with blood pressure medications, anticoagulants, diabetes treatments, and other prescriptions.
The goal shouldn’t be to replace every pharmaceutical with an herbal remedy.
It should be to become a more informed consumer.
Before purchasing another bottle, consider asking:
- What is the active ingredient?
- Does reliable clinical research support its intended use?
- Is there a less expensive generic equivalent?
- Could a lifestyle intervention help?
- Are there side effects or interactions I should know about?
Those five questions may save money—and help you avoid unnecessary treatments.
Final Thoughts: Your Medicine Cabinet Deserves a Second Look
Modern medicine has transformed healthcare and saved countless lives. But that doesn’t mean every product on the pharmacy shelf delivers equally impressive results.
Some are genuinely useful. Others offer modest benefits, questionable value, or marketing claims that exceed the evidence.
Traditional herbal practices can complement responsible healthcare, particularly when focused on symptom comfort, nutrition, and healthy daily routines.
The key is knowing the difference between a promising traditional remedy and a treatment supported by rigorous clinical research.
The smartest health decision isn’t always choosing the most expensive medicine—or the most natural alternative. It’s choosing what actually works, for the right reason, with the least unnecessary risk.
