What is Naproxen Sodium?

Naproxen Sodium, which often is referred to as just Naproxen (to avoid confusion), is the salt form of Naproxen, a nonsteroidal anti-inflammatory drug (NSAID); it is what makes up the brand-name medication Anaprox, and is responsible for all therapeutic effects and benefits. Anaprox contains 275mg of Naproxen, which comes in the form of a tablet for oral administration. Once administered, it is metabolized by the liver, creating metabolites during the process, and then excreted by the kidneys with a half-life ranging between 12-17 hours. The brand-name medication, Anaprox, can be purchased at My Drug Center, available to those with a valid prescription.


What is Naproxen used for?

Naproxen, or Anaprox, is an NSAID; these types of drugs are effective in reducing pain and inflammation (swelling) and therefore are used for a number of conditions. This may include rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, juvenile arthritis, tendonitis, bursitis, gout, dental pain, headaches, menstrual cramps, as well as other mild to moderate pain.


What does Naproxen do?

Naproxen reduces the total amount of prostaglandins in the body. Prostaglandins are a natural hormone found in most tissues and organs, produced by a majority of nucleated cells. These hormones have a wide range of functions in the body, including reactions of pain, inflammation, as well as fever. When you reduce the amount of prostaglandins in the body, you are also reducing the pain, inflammation, and/or fever of your condition.


How much Naproxen can I take?

The exact amount of Naproxen you can take will vary depending on many different factors. The condition that you are treating will be one of the main factors. For example, those with Osteoarthritis may take 275 mg to 550 mg twice per day; where as a person with acute gout may take an initial dose of 825mg just once the first day of the attack followed by 275 mg every 8 hours until the attack subsides. When treating other types of pain, it’s commonly suggested to take 550mg once, followed by 275mg every 6-8 hours (or 550 mg every 12 hours) as needed; depending on your condition, there will be a different maximum dose per day. Additionally, there are many other factors that will also determine how much Naproxen you can take both safely and efficiently, such as age, weight, and more. Speak with your doctor to learn more about how much you can take specifically.


How to take Naproxen?

Take this medication only the way your doctor has prescribed it to you; do not take more or less of a dose than directed, or for a longer period of time. Take your dose by swallowing the tablet whole, do not crush, chew, or break the tablet in half; flush it down with a glass of water. Avoid lying down in the first 10 minutes of taking your dose. You may take your dose with food or a glass of milk to prevent an upset stomach if your doctor allows it.  If you are still unsure how to take this medication, you may want to consider consulting your doctor before starting treatment.


How long does it take for Naproxen to get out of your system?

Naproxen has a half-life that ranges between 12-17 hours, which measures how long it takes for the concentration of the drug to be reduced by 50%. Though the exact length of time may vary between each individual, you can find an estimate as to how long it may take the drug to clear the system; by multiplying the half-life by 5. This would mean that it may take up to 85 hours (3.5 days) for the drug to clear from your system.


How long does Naproxen take to work?

Many patients will begin to feel relief after 60 minutes (1 hour) of administration, though the exact amount of time may vary. For more chronic conditions such as rheumatoid arthritis, when taking 2 doses per day is required, it may take up to 3 days for Naproxen to work properly. Keep in mind, we all react to medication differently, therefore, you may experience a later (or sooner) onset of action than another patient taking Naproxen; the exact amount of time will vary.


What is the difference between Naproxen and Ibuprofen?

Naproxen and Ibuprofen are both NSAIDs used for the treatment of various conditions causing pain, inflammation, and fever. However, they are different, and here are a few examples how: How often you may need to take the medication is a main difference, thanks to the half-lives of the two drugs. Generally, Naproxen has a longer duration of effects (and longer half-life), which means you won’t have to take Naproxen as often as you would Ibuprofen (Naproxen is generally taken every 8-12 hours as needed; Ibuprofen is generally taken every 4-6 hours as needed). The maximum dose in a 24 hour period is the next difference, since less Naproxen is needed for satisfactory relief, Naproxen has a max dose of 660mg. Since Ibuprofen is needed more often, it has a larger maximum dose, at 1,200mg per day. Drug interactions may also be an important difference to look at; Naproxen has about 25 more known drug interactions than Ibuprofen, such as certain antacid drugs (like h2 blockers and sucralfate), certain drugs (like cholestyramine) to treat cholesterol, and certain medications used for depression, like SSRIs and SNRIs. There may also be other differences between Naproxen and Ibuprofen that have not been listed here.
