Relafen vs Naproxen
Introduction
For patients with arthritis or other forms of chronic pain, certain drugs that inhibit the production of inflammatory compounds in the body can help manage symptoms and improve quality of life. Relafen (nabumetone) and Naproxen are two such drugs that are commonly prescribed for these conditions. Both medications belong to a class known as nonsteroidal anti-inflammatory drugs (NSAIDs), which work by reducing substances in the body that cause inflammation and pain. However, they have slightly different pharmacological properties. Relafen is a prodrug, meaning it converts into its active form only after ingestion, whereas Naproxen is not; this may result in fewer stomach-related side effects for some individuals taking Relafen compared to Naproxen. It's important to understand both medications carry risks, including potential gastrointestinal bleeding or heart issues; thus their use should be under proper medical supervision.

What is Relafen?
Nabumetone (the generic name for Relafen) is a nonsteroidal anti-inflammatory drug (NSAID) first approved by the FDA in 1991. It works by reducing levels of certain chemicals that cause inflammation and pain in the body, effectively "trapping" them at lower levels than usual. This medication is typically prescribed to relieve symptoms associated with rheumatoid arthritis and osteoarthritis, including swelling, stiffness, and joint pain. Nabumetone selectively inhibits COX-2 over COX-1 enzyme activity which can reduce some side effects such as gastrointestinal upset compared to other NSAIDs like Naproxen that inhibit both enzymes equally. However, all NSAIDs carry a risk of serious cardiovascular and gastrointestinal events so it's important to use the lowest effective dose for the shortest duration possible.
What conditions is Relafen approved to treat?
Relafen (nabumetone) is approved for the treatment of several conditions, including:
- Osteoarthritis, a degenerative joint disease often associated with aging
- Rheumatoid arthritis, a chronic inflammatory condition that can affect various joints in the body
- Other acute pain events where anti-inflammatory and analgesic effects are required
How does Relafen help with these illnesses?
Relafen, also known as nabumetone, aids in managing pain and inflammation by reducing the levels of prostaglandins in your body. It accomplishes this by inhibiting cyclooxygenase (COX), an enzyme that plays a crucial role in creating prostaglandins. Prostaglandins are messenger molecules involved in processes such as inflammation, fever, and pain signaling throughout the body. People with conditions like arthritis often have higher levels of these chemicals which contribute to their symptoms. Therefore, by limiting prostaglandin production through COX inhibition, Relafen can help manage the discomforts associated with inflammatory conditions and provide patients relief from their symptoms.
Similarly Naproxen is another nonsteroidal anti-inflammatory drug(NSAID) that works on reducing hormones causing inflammation and pain within the body providing relief for several conditions including stiffness caused due to muscle sprains or strains.
What is Naproxen?
Naproxen, sold under brand names such as Aleve and Naprosyn, is a non-steroidal anti-inflammatory drug (NSAID). This means it works by reducing the production of prostaglandins, substances in the body that cause inflammation. By doing so, naproxen helps to reduce pain and swelling. Naproxen was first approved by the FDA in 1976. Unlike Relafen which is another NSAID used for similar conditions, naproxen does not selectively inhibit COX-2 enzyme but inhibits both COX-1 and COX-2 enzymes. Its different mechanism of action means that its side-effect profile also varies from other NSAIDs like Relafen; for example, it could have a lower risk of gastrointestinal bleeding compared to some other NSAIDs. However, like all drugs in this class including Relafen, long-term use can increase the risk for heart attack or stroke. The effects on reducing inflammation make naproxen particularly beneficial for treating conditions like arthritis or acute injury where swelling is present.
What conditions is Naproxen approved to treat?
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that has been approved by the FDA for the treatment of:
- Osteoarthritis, rheumatoid arthritis, ankylosing spondylitis which are chronic conditions that cause pain and inflammation in the joints.
- Acute gout attacks, another form of arthritis where crystals deposit in the joints causing acute bouts of severe pain and swelling.
- Painful menstrual cramps
- General relief from minor aches and pains.
How does Naproxen help with these illnesses?
Naproxen is an anti-inflammatory drug that works by blocking the production of certain substances in the body that cause inflammation. This action helps to decrease swelling, pain, or fever. Naproxen's effect on the cyclooxygenase enzyme inhibits prostaglandin synthesis, resulting in lessened inflammation and relief from pain symptoms associated with conditions such as arthritis or acute injury. Its effectiveness and longer duration of action often make it a preferred choice over other non-steroidal anti-inflammatory drugs (NSAIDs) like Relafen for many patients suffering from chronic inflammatory conditions. While both medications can offer significant relief, Naproxen has been noted for its extended release formulation which provides consistent levels of medication throughout the day and night, potentially offering more consistent symptom control compared to some other NSAIDs.
How effective are both Relafen and Naproxen?
Both nabumetone (Relafen) and naproxen are nonsteroidal anti-inflammatory drugs (NSAIDs), known for their effectiveness in managing pain, inflammation, and fever. They were approved by the FDA only a few years apart, with naproxen getting its approval in 1976 and nabumetone in 1991. As they inhibit different enzymes involved in the inflammatory response, they may be prescribed under different circumstances.
The effectiveness of nabumetone and naproxen was directly studied in several double-blind clinical trials; these two drugs exhibited similar efficacy at managing symptoms such as osteoarthritis or rheumatoid arthritis-related pain, stiffness, swelling as well as demonstrating comparable safety profiles. In most studies conducted to measure efficacy treating arthritic conditions or soft tissue injuries no significant difference was observed between patients receiving nabumetone and those receiving naproxen.
Nabumetone is often preferred due to its more favorable gastrointestinal side effect profile compared to many other NSAIDs including Naproxen. It has been noted that Nabumentone causes less gastric irritation which is an important factor when considering long-term use for chronic conditions like osteoarthritis or rheumatoid arthritis.
On the other hand, while both medications have shown similar relief from symptoms associated with arthritis some studies suggest that Naproxen might provide slightly better pain control postoperatively than Nabumenthone. Nonetheless it's worth noting that Naproxen tends to interact with more medicines than Nabumenthone does making it potentially problematic for patients on multiple medications.

At what dose is Relafen typically prescribed?
Oral dosages of Relafen generally range from 1,000-2,000 mg/day, divided into two doses. However, studies have indicated that for most people 1,000 mg/day is sufficient to treat osteoarthritis and rheumatoid arthritis symptoms. For acute pain relief in adults the initial dose is usually 1,500-2,000 mg daily in divided doses. In either case of osteoarthritis or rheumatoid arthritis treatment or acute pain management, dosage can be adjusted after several weeks if there is no significant response. The maximum dosage that should not be exceeded under any circumstance is 2,000 mg/day.
At what dose is Naproxen typically prescribed?
Naproxen treatment typically begins with a dosage of 250-500 mg twice daily. The dose can subsequently be increased up to 1500 mg per day, divided into two doses and spaced approximately 12 hours apart based on the severity of symptoms and individual patient response. This maximum daily dose is usually reserved for patients with acute gout or severe arthritis pain that has not responded sufficiently to lower dosages. It's crucial to remember that Naproxen usage should always be under the guidance of a healthcare provider due to its potential side effects, especially if used at higher dosages or over extended periods.

- Chest pain spreading to your jaw or shoulder
- Sudden numbness on one side of the body
- Slurred speech
- Problems with vision/balance -Severe headaches
Moreover symptoms such as nausea, upper stomach pain, itching, tired feeling along with flu-like symptoms could be a sign of liver problems. In either case if you observe any severe reactions it's essential to seek immediate medical attention.
What are the most common side effects for Naproxen?
Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), may cause their own set of side effects:
- Indigestion, heartburn, stomach pain
- Nausea or vomiting
- Headache or dizziness
- Sleep problems (insomnia)
- Shortness of breath
- Mild skin rash or bruising
- Ringing in your ears -Anxiety and nervousness -Swelling of the hands or feet.
It's crucial to note that while some people might experience these side effects with Naproxen use, others may not. Always consult with your healthcare provider before starting any new medication for personalized advice based on your health history.
Are there any potential serious side effects for Naproxen?
While Naproxen is generally considered safe, it may cause some serious side effects in rare instances. If you notice any of these symptoms, stop taking Naproxen and call your doctor immediately:
- Signs of an allergic reaction: hives; difficulty breathing or swallowing; swelling of your face, lips, tongue, or throat
- Chest pain spreading to the jaw or shoulder, sudden numbness or weakness on one side of the body
- Sudden severe headache, confusion
- Shortness of breath even with mild exertion
- Swelling or rapid weight gain due to fluid retention
- Skin rash that spreads and causes blistering and peeling (a severe skin reaction)
- Kidney problems - little or no urination, painful urination
Remember to always take this medication as directed by a healthcare professional.
Contraindications for Relafen and Naproxen?
Both Relafen and Naproxen, along with most other NSAIDs, can increase the risk of serious stomach or intestinal problems. If you notice any signs of gastrointestinal bleeding such as black stools, persistent stomach pain or vomiting blood, please seek immediate medical attention.
Neither Relafen nor Naproxen should be taken if you are currently taking anticoagulants (blood thinners) like warfarin. Always inform your physician about all medications you are taking; anticoagulants will require careful monitoring to prevent dangerous interactions with Relafen and Naproxen.
Furthermore, these drugs should not be used before heart surgery due to an increased risk of heart attack or stroke. They may also cause kidney problems in certain patients, especially those who have impaired renal function or who use them for a prolonged period. Therefore it is important to discuss your full medical history with your healthcare provider before starting treatment.
How much do Relafen and Naproxen cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Relafen (500 mg) averages around $150, which works out to approximately $2.50/day, depending on your dose.
- The price of 30 tablets of Naprosyn (the branded version of naproxen; 500 mg each) averages around $130 or about $4.33/day.
Therefore, if you take a higher dosage range for naproxen like twice daily dosing (i.e., 1000 mg/day), then brand-name Relafen is less expensive on a per-day treatment basis. Please remember that cost should not be the primary consideration in determining which medication is right for you - effectiveness and safety are most important.
As for generic versions:
- Generic naproxen is available in packs ranging from 15 up to several hundred tablets (250mg, 375mg and 500mg strengths available), with costs as low as under $0.10/day at lower doses when buying larger quantities upfront.
- Nabumetone (generic relafen) can also be had in large quantities at similarly reduced prices per day compared to its branded counterpart.
Always consult with your healthcare provider before making any changes to your medication regimen.
Popularity of Relafen and Naproxen
Nabumetone, available under the brand name Relafen among others, was estimated to have been prescribed to about 1.2 million people in the US in 2020. Nabumetone accounted for just over 5% of nonsteroidal anti-inflammatory drug (NSAID) prescriptions in the US. However, it appears to be a widely used choice amongst “non-acidic” NSAIDs (the family of drugs that includes ibuprofen and naproxen). The prescription rate for nabumetone has been generally steady since its introduction.
Naproxen, including brand versions such as Aleve and Naprosyn among others, was prescribed to approximately 6 million people in the USA in 2020. In the US, naproxen accounts for close to a quarter of all NSAID prescriptions. This makes it one of the most commonly utilized medications within this class due its efficacy at relieving pain and inflammation across multiple conditions like arthritis and gout flares. The prevalence of naproxen use has remained consistent over recent years.
Conclusion
Both Relafen (nabumetone) and Naproxen have been widely used to treat pain, inflammation, and stiffness caused by conditions such as osteoarthritis or rheumatoid arthritis. Numerous clinical studies back their effectiveness over placebo treatments. In some cases, the drugs may be combined but this depends on careful assessment by a physician due to potential interactions.
Relafen works primarily by inhibiting prostaglandin synthesis while Naproxen works similarly but also possesses anti-inflammatory effects. They tend to be prescribed under different circumstances: Relafen is often chosen for its less frequent dosing schedule and lower risk of gastrointestinal side-effects compared to typical non-selective NSAIDs like naproxen.
Both medications are available in generic forms which represents significant cost savings especially for patients who must pay out-of-pocket. Both Relafen and Naproxen require an adjustment period meaning that full therapeutic effects may not be noticeable right away.
The side-effect profiles between these two drugs are similar, both being generally well-tolerated although Naproxen can more commonly cause gastrointestinal discomfort than Relafen. For both medications, patients must closely monitor any abnormal symptoms when starting treatment including severe stomach pain or blood in stool; they should seek medical help immediately if they notice any serious adverse reactions.
