Drug
Naproxen
Common brand names:
Aleve, Anaprox, NaprosynNaproxen/naproxen sodium are members of the nonsteroidal anti-inflammatory drug (NSAIDs) family. NSAIDs reduce inflammation (swelling), pain, and temperature. Naproxen is used to treat mild to moderate pain, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, primary dysmenorrhea, tendinitis, bursitis, and other conditions. Naproxen and naproxen sodium are available in prescription strength; naproxen sodium is also available in nonprescription strength.
Summary of Interactions with Vitamins, Herbs, & Foods
Negative Interactions
2- Potential Negative Interaction
Naproxen
Sodium
Naproxen may cause sodium and water retention. It is healthful to reduce dietary salt intake by decreasing the use of table salt and avoiding heavily salted foods.

- Potential Negative Interaction
Naproxen
White Willow
White willow bark (Salix alba) contains salicin, which is related to aspirin. Both salicin and aspirin produce anti-inflammatory effects after they have been converted to salicylic acid in the body. The administration of salicylates like aspirin to individuals taking oral NSAIDs may result in reduced blood levels of NSAIDs. Though no studies have investigated interactions between white willow bark and NSAIDs, people taking NSAIDs should avoid the herb until more information is available.

Supportive Interactions
3- Replenish Depleted Nutrients
Naproxen
Iron
NSAIDs cause gastrointestinal (GI) irritation, bleeding, and iron loss. Iron supplements can cause GI irritation. However, iron supplementation is sometimes needed in people taking NSAIDs if those drugs have caused enough blood loss to lead to iron deficiency. If both iron and naproxen are prescribed, they should be taken with food to reduce GI irritation and bleeding risk.

Stinging Nettle
This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.
In a controlled human study, people who took stinging nettle with diclofenac obtained similar pain relief compared to people taking twice as much diclofenac with no stinging nettle. More research is needed to determine whether people taking diclofenac might benefit from also taking stinging nettle.

- Reduce Side Effects
Naproxen
Licorice
The flavonoids found in the extract of licorice (Glycyrrhiza glabra) known as DGL (deglycyrrhizinated licorice) are helpful for avoiding the irritating actions NSAIDs have on the stomach and intestines. One study found that 350 mg of chewable DGL taken together with each dose of aspirin reduced gastrointestinal bleeding caused by the aspirin. DGL has been shown in controlled human research to be as effective as drug therapy (cimetidine) in healing stomach ulcers.

Naproxen
Copper
Supplementation with copper may enhance the anti-inflammatory effects of NSAIDs while reducing their ulcerogenic effects. One study found that when various anti-inflammatory drugs were chelated with copper, the anti-inflammatory activity was increased. Animal models of inflammation have found that the copper chelate of aspirin was active at one-eighth the effective dose of aspirin. These copper complexes are less toxic than the parent compounds, as well.

Potassium
Naproxen has caused kidney problems and increased blood potassium levels, especially in older people. People taking naproxen should not supplement potassium without consulting with their doctor.
