Naproxen is a powerful non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid class. It works by non-selectively inhibiting the cyclooxygenase enzymes (COX-1 and COX-2), which stops the production of prostaglandins—the chemical messengers responsible for signaling pain, fever, and swelling in the body. Unlike shorter-acting NSAIDs (like Ibuprofen), Naproxen has a longer "half-life," providing sustained relief from deep-seated inflammatory pain with fewer daily doses.
In Nigeria, Naproxen 500mg (available in brands like Naprosyn or quality generics) is a premier clinical choice for chronic joint and muscular conditions. It is available through registered pharmacies like Sanlive Pharmacy to ensure patients receive authentic, high-stability tablets manufactured under strict pharmaceutical standards and stored in cool, dry environments to maintain the molecular integrity of the 500mg dose.
Important: This is a potent, twice-daily medication. The "Stomach" Rule: You must take Naproxen with or immediately after a full meal to protect your stomach lining. The "Asthma" Warning: Do not use if you have ever had an asthma attack, hives, or an allergic reaction triggered by Aspirin or other NSAIDs. The "Heart & Kidney" Note: Long-term use can affect kidney function and slightly increase the risk of cardiovascular events; use the lowest effective dose for the shortest time possible. Do not use if you have an active stomach ulcer or severe heart failure.
Naproxen 500mg Tablets are primarily used to:
Provide long-lasting relief for Rheumatoid Arthritis and Osteoarthritis
Manage Ankylosing Spondylitis (stiffness and pain in the spine)
Resolve Acute Gout flare-ups (severe joint pain and swelling)
Relieve Menstrual Cramps (Primary Dysmenorrhea) and heavy period pain
Treat Acute Musculoskeletal Disorders, such as sprains, strains, and backache
Reduce post-operative pain and swelling following minor surgeries
Lower high fever when other treatments are unsuitable
Offer a convenient "twice-daily" dosing schedule for better patient compliance
This product is suitable for:
Adults and adolescents requiring strong, sustained anti-inflammatory action
Patients with chronic joint conditions who need all-day pain management
Individuals who find shorter-acting painkillers (like Paracetamol) ineffective for inflammation
Not recommended for: Children under 12 years of age unless specifically directed by a specialist. It is strictly contraindicated for individuals with active peptic ulcers or recent gastrointestinal bleeding. Use with extreme caution in elderly patients, as they are at higher risk for stomach and kidney side effects. Consult our pharmacist if you are taking blood thinners (like Warfarin) or blood pressure medications (like ACE inhibitors), as Naproxen can interfere with their effectiveness. Consult your doctor if you are pregnant; it is generally avoided, especially in the third trimester, as it can affect the baby's heart and circulation.
Take exactly as prescribed; for most inflammatory conditions, the dose is one (1) 500mg tablet twice daily
The "Meal" Tip: Always take your tablet with a full glass of water after eating to minimize gastric irritation
Swallow the tablet whole; do not crush or chew enteric-coated versions, as this destroys the stomach-protecting layer
Consistency is Vital: For chronic arthritis, it may take 2 weeks of regular use to feel the full anti-inflammatory benefit
The "Alcohol" Warning: Avoid heavy alcohol consumption while taking Naproxen, as it significantly increases the risk of stomach bleeding
If a dose is missed, take it with food as soon as you remember, but skip it if it is almost time for your next dose—never "double up"
Naproxen is effective, but because it influences the body's protective prostaglandins, some individuals may experience:
Heartburn, indigestion, or stomach pain (most common)
Dizziness, headache, or drowsiness
Ringing in the ears (Tinnitus)
Swelling of the ankles or feet (fluid retention)
Constipation or diarrhea
Rare but serious: Stomach ulcers or bleeding (indicated by black, tarry stools)
Rare: A widespread skin rash or "hives"
Rare: Visual disturbances or "blurred vision"
Seek immediate medical attention if you experience severe stomach pain, vomiting blood, sudden shortness of breath, or swelling of the face and throat.

Is Naproxen "stronger" than Ibuprofen?
While both are NSAIDs, Naproxen is longer-acting. A single dose of Naproxen lasts much longer than a dose of Ibuprofen, making it better for chronic pain that lasts all day or through the night.
Can I take this with Paracetamol?
Yes. Since they work in different ways, you can safely take Paracetamol alongside Naproxen if you need extra pain relief, provided you do not exceed the daily limits for either.
Why does it make my stomach hurt?
NSAIDs like Naproxen reduce the "good" prostaglandins that protect your stomach lining from its own acid. Always taking it with food is the best way to prevent this.
Where can I purchase Naproxen 500mg in Nigeria?
