Naproxen: Its uses, recommended doses, potential side effects, and possible drug interactions
Naproxen, a popular nonsteroidal anti-inflammatory drug (NSAID), is commonly used to relieve pain, reduce inflammation, and alleviate symptoms of various conditions such as arthritis, menstrual cramps, and headaches. However, long-term use of Naproxen can lead to several significant adverse effects that should not be overlooked.
Cardiovascular risks are one of the primary concerns associated with long-term Naproxen use. Prolonged or high-dose use of Naproxen increases the risk of serious cardiovascular events such as myocardial infarction (heart attack) and stroke. These risks are more pronounced with prolonged or high-dose use of NSAIDs in general [2][1].
Gastrointestinal complications are another potential issue with long-term Naproxen use. Chronic use of Naproxen can cause damage to the stomach lining, potentially resulting in stomach ulcers and severe gastrointestinal bleeding. This risk is amplified when Naproxen is combined with alcohol over time [5].
Long-term Naproxen use can also affect liver function. Although Naproxen is among the least likely NSAIDs to cause serious liver injury, prolonged use can elevate liver enzymes in about 4% of patients. Rarely, clinically apparent liver injury resembling acute hepatitis has been reported, typically within 1 to 6 weeks of starting therapy, with recovery upon discontinuation. Long-term liver damage is uncommon but possible, especially with high doses [3].
Kidney problems may also arise from long-term Naproxen use, particularly in individuals with pre-existing conditions like renal impairment, heart failure, liver dysfunction, or salt depletion. This can increase the risk of adverse renal reactions [4].
Other side effects associated with long-term Naproxen use include gastrointestinal discomfort (heartburn, indigestion), nervous system effects (confusion, dizziness), skin changes, and hearing issues, although these are less common [1].
It's important to note that combining Naproxen with alcohol over a long period can worsen the risk of stomach ulcers, liver disease, immune system weakening, and heart complications [5].
Given these risks, Naproxen should be used cautiously over the long term, ideally under medical supervision, with attention to cardiovascular, gastrointestinal, renal, and hepatic health [1][2][3][4][5]. Older adults, those with a history of ulcers or gastrointestinal bleeding, and people with heart conditions should exercise particular caution. Additionally, pregnant women should avoid taking Naproxen after around 20 weeks of pregnancy, and should consult a doctor for advice before taking Naproxen at any point earlier in pregnancy.
Naproxen is available in various types and strengths, including tablets, liquid capsules, and liquid, and it is essential to follow the recommended dosage guidelines. For instance, children between 2 and 12 years old should not exceed 1,000 mg in 24 hours, and children 12 years and older should not exceed 660 mg in 24 hours.
In the United States, over-the-counter (OTC) Naproxen is called Aleve. Prescription Naproxen is called Naprosyn and Anaprox. Naproxen sodium, which absorbs faster than regular Naproxen, is also available.
To mitigate some of the gastrointestinal side effects, Naproxen is available in enteric-coated tablets, and it's recommended to take Naproxen with food.
Remember, while Naproxen can provide significant relief for many conditions, its long-term use requires careful consideration and close monitoring to avoid potential adverse effects. Always consult a healthcare professional before starting any new medication, especially for long-term use.

- Psoriatic arthritis, a type of joint inflammation associated with psoriasis, may see improved symptoms with Naproxen, but the long-term use may pose cardiovascular risks requiring caution.
- Breast cancer patients should exercise care when considering Naproxen therapy, as long-term use could potentially increase the risk of colitis, an inflammation of the colon.
- For ulcerative colitis patients, Naproxen's potential gastrointestinal complications should be weighed against its pain-relieving benefits, as prolonged use could worsen existing gastrointestinal conditions.
- Diabetes patients should be aware that long-term Naproxen use might intensify their depressive symptoms, given its association with depression in certain medical-health conditions.
- Individuals with multiple sclerosis, a condition characterized by nerve damage and inflammation, may find temporary relief from Naproxen-induced pain relief, but should monitor for potential liver and kidney issues.
- Naproxen's long-term use should be approached with caution for those with a family history of hepatitis, HIV, bipolar disorder, or Alzheimer's disease, as it may potentially exacerbate or provoke such conditions.
- Given Naproxen's link to obesity-associated type 2 diabetes, people with AQ gene mutations, which might increase their diabetes risk, should consult a healthcare professional about Naproxen therapy.
- Science has yet to provide a predictive model for Naproxen's impact on health-and-wellness factors, such as cardiovascular health, but long-term use should ideally be monitored and managed under medical supervision.
- Certain medical-health conditions, such as multiple sclerosis, psoriasis, and colitis, can be better managed with Naproxen in the short-term, but long-term outcomes and potential adverse effects remain unknown.
- Health and wellness enthusiasts should understand that while Naproxen can alleviate symptoms, it's important to closely monitor one's health for potential side effects when using Naproxen long-term.
- To ensure the safest Naproxen use, always consult a healthcare professional before initiating Naproxen therapy and adhere to proper dosage guidelines to mitigate potential adverse effects.
