When taken as prescribed, NSAIDs are generally well tolerated. However, they can still cause some side effects. The side effects do depend on the type of NSAID that the patient uses. Certain types have an increased risk of serious side effects, whereas others are less dangerous, even as a long-term treatment option to reduce pain.
The more common side effects of NSAIDs include:
-
Irritation to the stomach lining can cause pain and discomfort
-
Heartburn and indigestion
-
Diarrhea or constipation
-
Nausea and vomiting
People who use NSAIDS frequently may find that they easily get bruised, even with small bumps. Some NSAIDs may also lead to stomach bleeding or make the person more likely to bleed if they cut themselves. This is especially the case with higher doses that the patient may obtain as a prescription drug.
In rare cases, NSAIDs may cause serious side effects. These can include:
-
Blood Pressure: NSAIDs can sometimes affect blood pressure levels. Some of these can result in high blood pressure. This is one of the known risk factors for cardiovascular disease. Patients who already struggle with high blood pressure should be wary of the potential adverse effects that certain NSAIDs may have. High blood pressure can cause an increased risk of heart attack and other potential problems.
-
Bleeding: Certain NSAIDs, such as aspirin, can also increase the risk of bleeding. This can sometimes lead to internal bleeding, especially with prolonged usage. If the patient takes blood thinners, then the risk of bleeding becomes even more severe.
-
Allergic Reactions: There are cases where people experience an allergic reaction when they take certain NSAIDs. NSAID allergic reactions may lead to difficulty breathing, rashes on the skin, and other dangerous complications.
-
Kidney Disease: People taking NSAIDs should ensure they understand how these pills affect their kidneys. NSAIDs can result in fluid retention, which affects the kidneys. People with existing kidney disease should ensure they look out for any signs that may signal a worsening of their condition.
