Napsav-D 500 Tablet belongs to the group of medications called analgesics. It treats migraine headaches. Besides this, it can also be used to reduce pain in rheumatoid arthritis, gout and dysmenorrhea (menstrual pain). Migraine is a condition characterized by intense headaches. Pain is a symptom that occurs due to various underlying conditions.

Napsav-D 500 Tablet is a combination of two drugs: Naproxen and Domperidone. Naproxen works by blocking the action of the cyclo-oxygenase (COX) enzyme in the body that produces certain chemical substances such as prostaglandins that cause pain and swelling. Domperidone is an antiemetic agent which prevents nausea and vomiting symptoms by blocking certain receptors (like dopamine and serotonin) that stimulate the vomiting centre (chemoreceptor trigger zone – CTZ) located in the brain.

Take Napsav-D 500 Tablet as prescribed by your doctor. You are advised to take Napsav-D 500 Tablet for as long as your doctor has prescribed it for you based on your medical condition. Common side-effects of Napsav-D 500 Tablet are dryness of the mouth, abdominal pain, constipation, drowsiness, dizziness, visual disturbances, hearing problems and headache. Consult your doctor if you feel any discomfort.

Before taking the Napsav-D 500 Tablet , let your doctor know about all your allergic or hypersensitivity reactions to medicines or food. If you are pregnant or breastfeeding, please tell your doctor so that your doctor will weigh the benefits and any potential risks before prescribing it to you. Also, inform the doctor if you have a history of heart rhythm problems or ulcers due to pain killers. Patients with age above 65 years, pre-existing cardiac diseases such as heart failure, hypertension or stroke, gastrointestinal bleeding (due to pain killers), gastric ulcers, respiratory diseases such as asthma, liver diseases, kidney diseases or bleeding disorders should use Napsav-D 500 Tablet only when prescribed by a doctor.

Napsav-D 500 Tablet is a combination of naproxen and domperidone. Naproxen is an anti-inflammatory (reduce inflammation) and analgesic (reduce pain) agent. It inhibits the synthesis of prostaglandins, which are inflammatory mediators, thereby reducing pain and inflammation. Domperidone acts by enhancing gastric peristalsis (movements) to empty stomach. Easy movement of food through the stomach helps in relieving nausea and vomiting. It blocks the dopamine receptors present at the chemoreceptor trigger zone (responsible for regulating nausea and vomiting).

Inform your doctor if you are taking any of the anticoagulants (warfarin), other NSAIDs (ibuprofen, ketorolac), corticosteroids (prednisolone), antidepressants (citalopram, fluoxetine, paroxetine, duloxetine, venlafaxine), or any other dietary or herbal supplements. Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) (other than aspirin) such as naproxen may increase the risk of heart attack or stroke and stomach ulcers. The risk of developing ulcers is higher if you have a history of ulcers, have bleeding disorders, older in age, alcoholic or have multiple diseases. The risk of having a heart attack increases if you smoke, or you or your family has a history of heart failure, stroke, or hypertension. Call for medical help immediately, if you experience chest pain, shortness of breath, blood in the stool or dark stools, heartburn, or any other abnormal signs.
