Over-the-counter (OTC) nonsteroidal anti-inflammatory drugs (NSAIDs), are among the most used medications globally. Millions of people rely on them for daily management of pain, inflammation, fever, and discomfort from conditions like headache, muscle strains, arthritis, and menstrual cramps. These medications are available without a prescription, causing many people to think that they are completely safe.
Although OTC NSAIDs are effective and generally safe when used correctly, they aren’t risk-free. Misuse, overuse, or use in high-risk individuals can lead to serious side effects.
What are NSAIDs?
NSAIDs are a type of medicine used for the treatment of pain and swelling. They can also help to reduce fever. Usually, lower-dose versions can be bought over the counter, while higher doses may be prescribed for long-term chronic conditions.
Some of the common NSAIDs include:
Nonprescription:
- Aspirin (Bayer, Excedrin)
- Ibuprofen (Advil, Motrin)
- Naproxen Sodium (Aleve)
Prescription:
- Celecoxib (Celebrex)
- Ketorolac (Toradol)
- Indomethacin (Indocin)
- Fenoprofen (Nalfon)
- Diclofenac (Voltaren)
These medications differ slightly in strength, duration of action, and risk profile. However, they all ork through similar biological mechanisms.
How do NSAIDs Work?
NSAIDs work by keeping the body from using COX-1 and COX-2 enzymes. These enzymes make prostaglandins, a group of fatty acids in the body that play a major role in pain and inflammation.
Benefits of Over-The-Counter NSAIDs
Over-the-counter NSAIDs have several benefits:
Effective Pain Relief
These medicines are highly effective for managing mild to moderate pain, including headaches and migraines, muscle aches and sprain, dental pain, back pain, and menstrual cramps. Unlike acetaminophen, NSAIDs address both pain and inflammation (swelling), making them especially useful for inflammatory conditions.
Anti-Inflammatory Action
Inflammation is a key contributor to pain in many conditions, such as tendonitis, arthritis, and sports injuries. NSAIDs help to reduce the swelling and stiffness, helping improve mobility and function.
Fever Reduction
NSAIDs help to lower fever by interfering with prostaglandins that regulate body temperature. This makes them useful during infections or flu-like illnesses.
Accessible and Convenient
Being available over the counter means that NSAIDs are easy to obtain, affordable, and familiar to most customers. This accessibility allows people to manage minor health issues without immediate medical visits.
Are Over-The-Counter NSAIDs Safe?
Yes. OTC NSAIDs are generally safe when used as directed for short term periods by healthy adults. However, safety depends on dosage, duration of use, age, individual health conditions, and concurrent medications. Risks arise when you exceed the recommended doses, combine NSAIDs improperly, or use them long-term without medical supervision.
Potential Risks and Side Effects of OTC NSAIDs
Using OTC NSAIDs poses some potential risks and side effects. Some of the most common risks include:
Gastrointestinal (GI) Risks
NSAIDs can cause stomach irritation and bleeding. They reduce prostaglandins that protect the stomach lining increasing the risk of stomach pain, heartburn, and ulcers. This is more likely to occur if they are taken in higher doses for a long period of time. Also, alcohol consumption and older age are contributing factors.
It is recommended to eat something before taking NSAIDs to provide a coating to the stomach thus protecting it. Your healthcare provider may also prescribe a proton pump inhibitor (PPI) to decrease the stomach acid.
Kidney Damage
NSAIDs can also lead to kidney damage. If you have existing kidney problems, only these medications when your healthcare provider prescribes it. Use the lowest dose for the shortest amount of time possible, and if you must use it for extended period, do it with close attention of your healthcare provider.
For individuals with existing kidney disease, NSAIDs can cause reduced kidney function, fluid, retention, and worsening chronic kidney disease.
Cardiovascular Risk
Some NSAIDs, especially when used long-term or at high doses, have been associated with increased blood pressure, higher risk of heart attack, and stroke. The FDA requires that all NSAIDs packaging include this serious risk. Naproxen may have a lower cardiovascular risk compared to other NSAIDs, but caution is still advised.
Increased Bleeding Risk
Nonsteroidal anti-inflammatory drugs interfere with platelet function, which can increase the risk of bleeding. This is particularly common among people who take blood thinners, have bleeding disorder, or a preparing for surgery.
Allergic Reactions
Although rare, NSAIDs can lead to allergic reactions such as swelling, rash, and breathing difficulties. If you experience any of these symptoms, stop use immediately and seek medical care.
Who Should Avoid Using OTC NSAIDs?
There are many people who should avoid taking NSAIDs due to their higher risk of severe complications. Below are some groups of people who may need to avoid using these drugs.
People with Kidney Problems
NSAIDs temporarily reduce blood flow to the kidneys. If your kidneys have a problem, this reduced blood flow can cause damage to them. In some case, it can lead to acute (sudden) kidney injury.
Adults Aged 65 or Older
People aged 65 and older have a greater risk for serios side effects from many medications, including NSAIDs. Older adults have a greater risk of GI bleeding, heart problems, and kidney damage when taking NSAIDs.
People with Stomach Ulcers or Bleeding
Most NSAIDs irritate the stomach lining, which leads to side effects such as heartburn and nausea. If you have any of these GI problems or at risk of developing them, avoid taking nonsteroidal anti-inflammatory medicines.
During Pregnancy
If you’re pregnant, NSAIDs are among some of the drugs to avoid. Taking them after week 20 of pregnancy can raise the risk of harming the fetus. It can affect your baby’s heart, kidney, or lung development.
Hypertension Cases
If you have high blood pressure or hypertension, you should confirm with a healthcare practitioner before taking NSAIDs. Most of these drugs can increase blood pressure and many also interact with most common blood pressure medications.
Other risk groups include people with type 2 diabetes and those taking blood thinners or steroids.
Proper Use of OTC NSAIDs
Generally, over-the-counter NDAIDs are safe to ease occasional aches and pains. However, you need to be smart about using them. These tips can help to minimize any side effects or health risks:
Keep track of doses and timing: Take only the advised amount for the shortest period of time needed. Higher doses are likely to lead to health problems. For pain, don’t use for more than 10 days and fever not more than 3 days.
Talk with your healthcare provider first: Share with them details of all the prescription and OTC medications that you take. They can tell if an NSAID is not safe for you.
Read all medicine labels: Don’t take two or more OTC products with the same active ingredients. It’s likely to cause an overdose of increase the side effects.
Avoid mixing NSAIDs: Do not take multiple NSAIDs at the same time (e.g., ibuprofen and naproxen together), as this increases the risk of side effects.
Beware of symptoms such as kidney problems, stomach problem, hypertension, rashes, and heart issues.
If you are experiencing persistent pain, it is recommended to consult a healthcare provider rather than relying on OTC NSAIDs for an extended period.
