Naproxen vs Diclofenac
Introduction
In patients dealing with chronic inflammatory conditions such as arthritis, or those experiencing acute pain from injuries, certain drugs that inhibit the production of compounds responsible for inflammation and pain can provide significant relief. Two such medications are Naproxen and Diclofenac. Both belong to a class of drugs called Nonsteroidal Anti-inflammatory Drugs (NSAIDs), which work by blocking enzymes known as cyclooxygenases involved in producing prostaglandins - substances in the body causing inflammation and pain.
Naproxen is typically prescribed for relieving discomfort associated with various forms of arthritis, gout attacks, tendonitis, bursitis and menstrual cramps. On the other hand, Diclofenac is often used to treat migraines, dental pain, rheumatoid arthritis among others. Each has its own set of side effects; Naproxen may cause stomach upset while Diclofenac might result in liver problems when used long-term or at high doses.

What is Naproxen?
Naproxen and Diclofenac are both members of the NSAID (Non-steroidal anti-inflammatory drug) class which represented a significant progression from traditional analgesics. Naproxen was first approved by the FDA in 1976. It operates by reducing levels of prostaglandins, hormones that are responsible for causing inflammation and pain within your body. It is prescribed primarily for relief from different types of pain, fever, swelling, and stiffness caused by conditions such as osteoarthritis, rheumatoid arthritis, psoriatic arthritis among others. Naproxen has a selective influence on COX-2 enzymes with only minor impact on COX-1 enzymes which results in it having fewer gastrointestinal side effects than other NSAIDs that have stronger effects on these two types of cyclooxygenase enzymes.
On the other hand, Diclofenac works similarly but is more often used to treat severe intense forms of pain after surgery or for chronic conditions like rheumatoid arthritis. Both drugs present certain risks if taken long-term including heart attack or stroke and potential stomach ulcers so should be used at the lowest effective dose under professional medical guidance.
What conditions is Naproxen approved to treat?
Naproxen is approved for the treatment of a variety of pain-related conditions, including:
- Rheumatoid arthritis and osteoarthritis
- Ankylosing spondylitis
- Tendinitis and bursitis
- Acute gout attacks
- Menstrual cramps and other types of acute pain
How does Naproxen help with these illnesses?
Naproxen works to manage pain and inflammation by reducing the production of prostaglandins, chemicals that promote inflammation, pain, and fever in the body. It does this by inhibiting enzymes known as cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), which are involved in prostaglandin production. Prostaglandins play a crucial role in our body's inflammatory response to injury or illness, bringing about symptoms like swelling, redness, heat and pain. By reducing prostaglandin levels through COX inhibition, Naproxen can alleviate these symptoms of inflammation.
Similarly, Diclofenac is also an NSAID that functions by inhibiting COX enzymes hence reducing the synthesis of prostaglandins. However it tends to have a stronger affinity for COX-2 than COX-1 which may result in less gastrointestinal side effects compared to other NSAIDs but higher cardiovascular risks. Thus when deciding between Naproxen or Diclofenac for managing their condition, patients should consider both efficacy against symptoms as well as potential side effect profiles.
What is Diclofenac?
Diclofenac, sold under various brand names such as Voltaren and Cataflam, is a non-steroidal anti-inflammatory drug (NSAID) that relieves pain, reduces inflammation, and lowers fever. It works by inhibiting the production of prostaglandins, substances in the body that cause pain and inflammation. Diclofenac was first approved by the FDA in 1988.
Unlike naproxen, diclofenac is available not only in oral formulations like tablets or liquid-filled capsules but also as skin gels or patches for direct application to painful areas. This versatility allows it to be used for a broader range of conditions including arthritis-related discomfort and sports injuries.
It's worth noting though that while diclofenac can be more effective than other NSAIDs such as naproxen at reducing acute pain symptoms when taken over short periods of time it does have a higher risk profile with potential side effects including heart problems and issues related to stomach irritation.
What conditions is Diclofenac approved to treat?
Diclofenac is a potent nonsteroidal anti-inflammatory drug (NSAID) that has been approved for the treatment of:
- Osteoarthritis and rheumatoid arthritis
- Ankylosing spondylitis, which is a type of inflammatory arthritis affecting the spine
- Acute gout attacks
- Pain caused by kidney stones or gallstones
Its powerful analgesic and anti-inflammatory properties make it an effective choice in managing these conditions.
How does Diclofenac help with these illnesses?
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID), similar to Naproxen, and works by inhibiting the production of prostaglandins, substances in the body that cause inflammation and pain. Diclofenac is often used for conditions like osteoarthritis, rheumatoid arthritis, gouty arthritis, or ankylosing spondylitis as it can alleviate symptoms such as swelling and joint stiffness in these conditions. It's worth noting that while both drugs are effective at managing pain and reducing inflammation, Diclofenac has been shown to have superior gastrointestinal safety compared to Naproxen. This means it may be better tolerated by patients with sensitive stomachs or those who have previously experienced gastrointestinal side effects from NSAIDs.
How effective are both Naproxen and Diclofenac?
Both naproxen and diclofenac are nonsteroidal anti-inflammatory drugs (NSAIDs) that have been extensively used for their analgesic, antipyretic, and anti-inflammatory properties. Naproxen was approved by the FDA in 1976 with diclofenac following shortly after in 1988. As both these medicines act on similar pathways to reduce inflammation and pain, they may be prescribed interchangeably depending upon the patient's individual circumstances.
The effectiveness of naproxen versus diclofenac has been directly studied in various clinical trials; one study conducted in 1993 showed comparable efficacy between the two medications when treating rheumatoid arthritis. Both drugs demonstrated promising safety profiles with a low incidence of serious adverse events. In this trial, no significant differences were observed regarding efficacy or tolerability between patients receiving diclofenac and those receiving naproxen.
A meta-analysis conducted in 2010 affirmed the effectiveness of naproxen for managing symptoms such as pain and inflammation associated with conditions like osteoarthritis starting from the first week of treatment. Its side effect profile is favorable compared to many other NSAIDs due to its lower cardiovascular risk potential, making it suitable even for elderly populations who are at high risk for heart disease.
On another note, a review published in 2017 indicated that while both drugs show similar efficacy levels against placebo when treating acute pain situations like postoperative or dental pain, diclofenac tends to edge out slightly ahead possibly due to its additional mechanism action involving inhibition of certain prostaglandin receptors which might provide more localized relief from inflammatory responses. Despite being third-line options after acetaminophen/paracetamol or aspirin according to some guidelines — mainly due to gastrointestinal risks associated with prolonged use—both medications play an essential role where others fail or aren't feasible solutions.

At what dose is Naproxen typically prescribed?
Oral dosages of Naproxen range from 250–500 mg twice a day, but studies have indicated that 500 mg/day is usually sufficient for treating mild to moderate pain, inflammation or fever in most people. Children and adolescents may be started on lower doses such as 5-7mg/kg every 8-12 hours. In either population, dosage can be increased after a few weeks if there is no response. The maximum dosage that should not be exceeded in any case is 1500 mg/day. On the other hand, oral dosages of Diclofenac vary between individuals and conditions being treated but typically ranges from 50–150 mg per day divided into two or three doses. As always, it's essential to consult with your healthcare provider before starting any new medication regimen.
At what dose is Diclofenac typically prescribed?
Diclofenac treatment is typically initiated at a dose of 50–100 mg/day, divided into two or three doses. Dose can then be increased to a maximum of 150 mg/day if necessary, which should be split into three equal doses spaced evenly throughout the day. For instance, one could take 50mg in the morning, midday and evening. If there's no response to treatment after several weeks with this regimen, your healthcare provider may consider other options as diclofenac might not be the best choice for you. As always, it's important to follow all instructions provided by your doctor or pharmacist when taking medication.

- Symptoms related to kidney problems such as changes in the amount of urine
Should any patient using Diclofenac experience these side effects, they should stop taking the medication immediately and seek professional medical assistance.
Contraindications for Naproxen and Diclofenac?
Similar to other NSAIDs (Non-Steroidal Anti-Inflammatory Drugs), both Naproxen and Diclofenac may increase your risk of heart attacks or strokes, especially if used long term. If you notice symptoms such as chest pain, shortness of breath, weakness on one part or side of your body, slurred speech, consult with a healthcare provider immediately.
Naproxen and Diclofenac should be avoided by patients who are already taking anticoagulants (blood thinners) like warfarin or aspirin because they can lead to an increased risk of serious gastrointestinal bleeding. Always inform your physician about all medications you are currently using; those drugs that affect blood clotting will require careful monitoring during treatment with either Naproxen or Diclofenac to avoid dangerous interactions.
If you have high blood pressure, heart disease, liver cirrhosis, kidney disease or fluid retention issues these medications may not be suitable for you. Consultation with a healthcare professional is necessary before starting any new medication regimen.
How much do Naproxen and Diclofenac cost?
For the brand name versions of these drugs:
- The price for 60 tablets of Naproxen (500 mg), also known as Aleve, averages around $160, which works out to approximately $2.66 - $5.33/day depending on your dose.
- The price for 30 Diclofenac (50 mg) tablets is about $130, working out to roughly $4.33/day.
Thus, if you are in the higher dosage range for Naproxen (i.e., 1500 mg/day), then brand-name Diclofenac is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions of Naproxen and Diclofenac, costs are significantly lower:
- Generic Naproxen comes in packs ranging from 100 up to 500 capsules with an approximate daily cost varying between $0.15 and $0.45 based on typical dosages between 250mg and 750mg.
- Generic Diclofenac can be purchased in packages from as small as 20 up to as many as several hundred tablets with prices starting from merely about $.10 per day when bought upfront and reaching no more than just under $.40 per day even at larger doses such as those approaching or equaling its maximum recommended daily limit of ~200 milligrams.
Popularity of Naproxen and Diclofenac
Naproxen, which is available in both prescription and over-the-counter forms, was estimated to have been used by about 15 million people in the US in 2020. Naproxen accounted for approximately 13% of all nonsteroidal anti-inflammatory drug (NSAID) prescriptions in the US. It has remained a popular choice due to its efficacy and affordability.
Diclofenac, often prescribed under brand names such as Voltaren or Cambia, was utilized by roughly 8 million individuals in the USA during the same period. Diclofenac accounts for just under 10% of NSAID prescriptions and can be administered via various routes such as oral, topical or injection versions depending on specific patient needs. The usage rate for diclofenac has generally increased over recent years due to its versatility and broad range of indications.
Conclusion
Both Naproxen and Diclofenac are nonsteroidal anti-inflammatory drugs (NSAIDs) used for relieving pain, inflammation, and stiffness caused by various conditions like arthritis and gout. They have been widely used over the years with substantial evidence supporting their effectiveness in managing these conditions. Sometimes both medications might be utilized together under careful physician supervision, but this needs to be approached with caution due to possible enhancement of side effects.
Naproxen works by reducing the levels of prostaglandins - substances that cells produce in response to injury which cause pain, swelling, and fever. Diclofenac also reduces prostaglandins but is more potent than naproxen.
Both medicines are available as generics offering significant cost savings for those who pay out-of-pocket. Patients may need time to notice improvements after starting either medication since they work on reducing inflammation which is a gradual process.
The safety profile between naproxen and diclofenac is quite similar; they are well-tolerated when taken as directed although gastrointestinal issues such as stomach ulcers or bleeds can occur especially when taken long-term or at high doses. Other potential side effects include cardiovascular risks particularly if you have existing heart disease.
Patients should monitor any changes in symptoms carefully while taking these medications and seek immediate medical attention if there's unexplained weight gain or swelling, shortness of breath, severe skin reactions or worsening stomach symptoms.
