Naproxen Sodium

Anaprox DS 550mg Tablet

Anaprox DS 550mg tablet is an immediate-release form of naproxen sodium, a nonsteroidal anti-inflammatory drug or NSAID. This FDA-approved drug is primarily used to manage pain and inflammation associated with various conditions such as ankylosing spondylitis, rheumatoid arthritis, osteoarthritis, and menstrual pain. This drug reduces inflammation by inhibiting the production of prostaglandins. These substances contribute to inflammation in the body. Anaprox DS should be taken as directed by a healthcare provider, with considerations for special dosages in children and elderly due to different absorption rates. Important to note are the potential side effects ranging from common digestive disturbances to serious cardiovascular and gastrointestinal risks. In case of an overdose or if you notice any serious side effects like chest pain, bleeding, or more, contact your doctor immediately.

Product Overview

Anaprox DS 550mg tablets are a form of naproxen sodium, classified under nonsteroidal anti-inflammatory drugs (NSAIDs). This medication is primarily used to address moderate to severe pain and reduce inflammation in various medical conditions. It is effective against chronic illnesses like rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and polyarticular juvenile idiopathic arthritis in children. It also provides relief from acute pain conditions such as menstrual cramps, tendonitis, bursitis, and acute gout attacks.

The standard adult dose for chronic conditions like arthritis is 550 mg twice daily, which may be adjusted based on efficacy and tolerance. For acute conditions, the initial dose may be higher, followed by lower maintenance doses. Special considerations are given to individuals over 65 or those with kidney or liver issues, where dosages are carefully adjusted to prevent accumulation and potential toxicity.

While Anaprox DS is effective in pain management, it carries risks of significant side effects. Common adverse reactions include gastrointestinal upset, heartburn, and nausea. More severe risks involve cardiovascular events like heart attack and stroke, particularly in long-term users or those with existing heart conditions. It may also lead to serious gastrointestinal issues such as ulcers and bleeding, especially in older adults or those taking certain other medications. Patients are advised to take this medicine with food or antacids to mitigate stomach upset and not to lie down immediately after ingestion to avoid esophageal discomfort. It’s crucial for users to follow their healthcare provider’s instructions closely and discuss any potential interactions with other medications they are taking.

How Does Anaprox DS Work?

Anaprox DS is part of a category of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs work by reducing pain, inflammation (swelling and damage), and fever. Anaprox DS may decrease swelling by lowering levels of prostaglandin, a hormone-like substance that typically causes inflammation. After taking a dose of Anaprox DS, the drug can remain active in your body for up to 4 days. The frequency of doses depends on the specific condition being treated—you may need to take a dose every 6 to 12 hours or up to twice a day. Generally, you will continue taking the medication until your symptoms resolve. The appropriate dosage for your condition will be determined by your doctor. Once you stop taking Anaprox DS, it should be completely eliminated from your body in about 4 days. If you have any questions about how long Anaprox DS lasts in your system, consult your doctor or pharmacist.

Boxed Warning

FDA Warnings: This drug carries boxed warnings, which are the most serious kind of warning issued by the Food & Drug Administration or FDA. These warnings inform doctors and patients about potential dangerous effects of the drug.

  • Heart Disease Risk: Anaprox DS may increase the risk of heart disease. Using this drug long-term or in high doses can heighten this risk. People with existing heart disease and risk factors, such as high blood pressure, are at an increased risk of experiencing this side effect. Anaprox DS should not be used for pain relief before or after heart bypass surgery as it could raise your risk of heart attack and stroke.
  • Risk of Ulcers and Bleeding: Anaprox DS can cause ulcers & bleeding in your stomach (including intestinal). This can occur at any time during treatment, sometimes without any warning symptoms, and can be life-threatening. The risk is higher if you are older than 65 years.

Precautions

  • Risk of Heart Attack or Stroke: Anaprox DS can increase the risk of a fatal heart stroke or attack, even if you don’t have any risk factors. Don’t use this medication just after or before heart bypass surgery (coronary artery bypass graft also called CABG).
  • Stomach or Intestinal Bleeding: Anaprox DS may cause intestinal or stomach bleeding, which may be fatal. These conditions can happen without warning, particularly in older adults.

Anaprox DS Interactions

Prescription Anaprox DS oral tablets may interact with other vitamins, drugs, or herbs you may be taking. An interaction occurs when another substance affects how a medicine works, which can be harmful or stop the drug from being effective. To minimize the risk of interactions, it is important for your doctor to manage all your medications meticulously. Make sure to inform your doctor about all medications, vitamins, or herbs you’re currently taking. If you want to know how Anaprox DS might interact with something else you’re taking, consult with your doctor or pharmacist. Below are examples of drugs that can cause interactions with Anaprox DS.

  • Antidepressant Drugs: Using selective serotonin reuptake inhibitors (SSRIs) along with Anaprox DS can increase your risk of stomach and intestinal bleeding. Examples of SSRIs that can interact with Anaprox DS include:
    • Fluoxetine (Prozac)
    • Paroxetine (Brisdelle, Paxil)
    • Citalopram (Celexa)
    • Fluvoxamine (Luvox)
  • Blood Pressure Drugs: Anaprox DS may reduce the effectiveness of your blood pressure medications. Additionally, if you are older than 65 years, combining Anaprox DS with certain blood pressure medications could harm your kidneys. Examples of blood pressure drugs that can interact with Anaprox DS include:
    • Angiotensin II Receptor Blockers: like losartan (Cozaar) & Diovan (valsartan)
    • Angiotensin-Converting Enzyme (ACE) Inhibitors: such as Zestril (lisinopril)
    • Diuretics: such as furosemide (Lasix) and hydrochlorothiazide 
    • Beta-Blockers: such as metoprolol tartrate (Lopressor) and propranolol (Inderal LA)
  • Heartburn Drugs and Stomach Protectants: Using medications that treat heartburn or protect the stomach alongside Anaprox DS can slow down the pain-relieving effects of Anaprox DS. Examples of these medications include:
    • Magnesium oxide
    • Aluminum hydroxide
    • Sucralfate (Carafate)
  • Nonsteroidal Anti-inflammatory Drugs (NSAIDs): Taking Anaprox DS with other NSAIDs can heighten your risk of stomach and intestinal bleeding. Examples of NSAIDs that can interact with Anaprox DS include:

    • Ibuprofen (Motrin, Advil)
    • Aspirin (Bufferin, Bayer)
    • Flurbiprofen
    • Etodolac
    • Ketorolac
  • Cholestyramine: If you take cholestyramine (Prevalite) along with Anaprox DS, your body may absorb Anaprox DS more slowly than normal. This could delay the effectiveness of Anaprox DS in relieving your symptoms.
  • Lithium: Taking Anaprox DS with lithium (Lithobid) can increase the lithium levels in your body to potentially dangerous levels.
  • Methotrexate: If you take methotrexate (Trexall) together with Anaprox DS, it can result in dangerously high levels of methotrexate in your body, which can be harmful.
  • Warfarin: Using warfarin (Jantoven) in conjunction with Anaprox DS heightens your risk of experiencing stomach and intestinal bleeding.

[Note: This isn’t a complete list, and there could be other drugs that interact with Anaprox DS. Make sure to tell your doctor any prescription, over-the-counter medicines, and herbal products you’re taking.]
