Ibuprofen is one of the most used analgesics and anti-inflammatories to relieve headaches, muscle discomfort, fever, menstrual pain or inflammation. Being available without a prescription in many countries, it is often perceived as a “soft” or low-risk medication. However, medical evidence underscores a key point: taking it frequently, over many days, or in high doses can increase the risk of major adverse effects, especially on the stomach, heart, blood pressure, and kidneys.

Ibuprofen belongs to the group of non-steroidal anti-inflammatory drugs, known as NSAIDs or NSAIDs. These medications can be useful when used occasionally and in the appropriate dosage, but they are not intended to become a daily solution without medical supervision.

The FDA, the United States health authority, warns that long-term continuous use may increase the risk of heart attack or stroke, and also includes a specific warning about stomach bleeding.

What happens in the body when you take ibuprofen often

Ibuprofen works by blocking enzymes related to the production of prostaglandins, substances that are involved in pain, inflammation and fever. This mechanism explains why it can relieve symptoms, but also helps to understand its risks: prostaglandins perform protective functions in different parts of the body, such as the lining of the stomach, renal circulation and some cardiovascular processes.

Therefore, when ibuprofen is taken repeatedly, the problem is not just “more medication,” but sustained exposure to effects that can alter important balances. The risk increases with higher doses, prolonged use, older age, history of ulcer, kidney disease, hypertension, heart problems, frequent alcohol consumption or combination with other drugs such as anticoagulants, corticosteroids or aspirin. MedlinePlus warns that NSAIDs such as ibuprofen can cause ulcers, bleeding, or perforations in the stomach or intestine, even without prior symptoms.

Risk of gastritis, ulcers and digestive bleeding

One of the best-known consequences of frequent use of ibuprofen is gastrointestinal damage. It can cause heartburn, stomach pain, nausea, gastritis, ulcers and, in severe cases, digestive bleeding.

The risk is not limited to those who already have discomfort: according to experts at the Mayo Clinic, bleeding in the stomach or intestine can appear without warning signs, and is more likely in people over 60 years of age, smokers, those who consume alcohol regularly or those who use certain medications such as anticoagulants or steroids.

This is important because many people continue taking ibuprofen for recurring pain without consulting, and only pay attention when severe pain, dark stools, bloody vomiting, or anemia appear. These signs require urgent medical attention.

Increased cardiovascular risk

Frequent use of ibuprofen can also have cardiovascular consequences. The FDA warns that NSAIDs may increase the risk of heart attack or stroke, especially when used for long periods or in high doses. This risk may be greater in people with previous cardiovascular disease, but is not limited exclusively to them.

The Mayo Clinic also notes that ibuprofen can increase the risk of heart attack or stroke, and that this risk is more likely in people with heart disease or in those who use it for a long time. Therefore, it is not a minor medication for those who have hypertension, a history of heart attack, heart failure, coronary heart disease or cardiovascular risk factors.

Kidney damage or worsening kidney problems

Another relevant consequence is the possible impact on the kidneys. Ibuprofen can reduce mechanisms that help maintain renal blood flow, especially in situations of dehydration, previous kidney disease, advanced age, hypertension, diabetes, or use of certain blood pressure medications.

Experts at the Mayo Clinic include kidney disease among the conditions that require special caution when using ibuprofen, because it can worsen existing problems. In practice, this means that it is not advisable to use it repeatedly without control if you have a history of kidney disease or if you take chronic medication for pressure, heart or fluid retention.

Blood pressure, fluid retention and heart

Ibuprofen can also interfere with blood pressure control and promote fluid retention in some people. This does not mean that taking it alone will cause a serious problem, but it does mean that frequent use may be inappropriate in patients with hypertension, heart failure or cardiovascular disease.

The British NHS warns that the risk of serious side effects is higher when ibuprofen is taken in high doses or used for a long time. NHS Inform also notes that high doses over long periods may increase the risk of stroke and heart attack.

When should you avoid it or consult before

Ibuprofen is not recommended for everyone. Those with a history of ulcer or digestive bleeding, kidney disease, heart disease, poorly controlled hypertension, asthma sensitive to anti-inflammatories, treatment with anticoagulants, frequent use of alcohol or pregnancy should take special care.

NHS Inform indicates that pregnant women should not take ibuprofen unless medically advised and mentions paracetamol as a common alternative for short-term pain or fever, depending on the case.

It is also worth checking if the pain requires taking it for several days in a row, if it reappears frequently or if a higher dose is needed each time. In those cases, the main problem is not just the medication: there may be an underlying cause that requires diagnosis.

The safest rule: lowest dose and shortest possible time

The general recommendation of health authorities is to use ibuprofen in the lowest effective dose and for the shortest time necessary. This is not about demonizing it: it can be useful and safe for many people when used well. The risk appears when it becomes normal to take it “just in case”, every day, after training, whenever there is body fatigue or as an automatic response to any discomfort.

In short, taking ibuprofen frequently can increase the risk of gastric irritation, ulcers, digestive bleeding, kidney problems, high blood pressure and cardiovascular events. Science does not say that it should always be avoided; It says something more precise: it should not be used chronically or repeatedly without medical evaluation, especially if there are risk factors.
