General Information About Anaprox

Anaprox is an analgesic used for pain relief. Formulated with a high concentration of naproxen, the drug effectively alleviates mild-to-moderate pain with inflammation in musculoskeletal trauma and post-dental extraction. It is also effective against pain caused by post-partum cramping and dysmenorrhea. Anaprox is a product of Roche Holding AG, a global healthcare company headquartered in Basel, Switzerland.

Generic names: Naproxen

Active ingredients

Anaprox (naproxen) is an analgesic belonging to a class of medications called non-steroidal anti-inflammatory drugs (NSAIDs). Apart from its pain-relieving properties, naproxen also has analgesic and anti-inflammatory properties. Naproxen exerts its inhibitory effects on cyclooxygenases (COX), thereby reducing prostaglandin biosynthesis. At the same time, it inhibits thromboxane synthase to reduce the production thromboxane A2. Together, these actions result in less inflammation and platelet aggregation.

Conditions treated

The indications of Naproxen DS are as follows:

  • Mild-to-moderate pain (with inflammation) in post-dental extraction and musculoskeletal trauma;
  • Pain linked to dysmenorrhea and post-partum cramping.

Dosage information

Each bottle comes with 100 film-coated Anaprox tablets, which are blue in color.

For adults, take 1 tablet 2 times a day. Do not take more than 1,375mg per day.

What is pain?

Clinically, pain is defined as an unpleasant emotional and sensory experience related to actual/potential tissue damage. More than just an unpleasant physical sensation, pain is often associated with significant psychological and social costs. There are 3 major types of pain, namely acute pain, chronic pain and cancer pain. Acute pain is usually short-lived and will resolve itself as the body recovers from trauma. In contrast, chronic pain is a debilitating condition that lasts long after the trauma is healed.

What is dysmenorrhea?

Dysmenorrhea is a symptom of painful menstruation, characterized by cramping and labor-like pain. It may also cause pain at the lower abdomen. The condition can be divided into two categories, which are primary dysmenorrhea and secondary dysmenorrhea. NSAIDs such as naproxen are approved by FDA in the treatment of dysmenorrhea. In addition to pharmacological therapies, the condition can be managed through non-pharmacological approaches such as exercise and lifestyle modification.

What if I overdose on Anaprox?

In case of overdose, seek medical help immediately. Contact a regional Poison Information Center or go to the nearest hospital. Some of the signs of overdose are dizziness, epigastric pain, hypoprothrombinemia, metabolic acidosis, disorientation, apnea, abdominal discomfort, indigestion, nausea, and vomiting. You should seek medical attention even if you do not experience any signs of an overdose.

What if I miss a dose of Anaprox?

If you miss a dose, take it as soon as you remember. If it is almost time for the next dose, you should skip the missed dose and take the next dose instead. Do not take 2 doses of Anaprox at the same time, as this may cause overdose.
