Synflex Tablet: Uses, Side Effects, Dosage and Precautions
Questions about synflex tablet uses are very common in Pakistan, because Synflex is one of the most widely dispensed painkillers at pharmacies here. This guide explains what Synflex contains, what it is used for, how it works, the dosage information found in standard references, its side effects and the precautions every patient should know before using it.
This article is for general information only and is not medical advice. Always consult your doctor or pharmacist before using any medicine.
What Is Synflex Tablet?
Synflex is a brand name for the generic medicine naproxen (in its sodium form, naproxen sodium), which belongs to a group of medicines called NSAIDs — non-steroidal anti-inflammatory drugs. Naproxen reduces pain, inflammation (swelling) and fever by blocking substances in the body called prostaglandins. In Pakistan, Synflex tablets are commonly available in strengths such as 275 mg and 550 mg of naproxen sodium, and the medicine is intended for short-term relief of pain and inflammatory conditions under medical guidance.
Naproxen is a prescription-strength anti-inflammatory in many settings, which is why understanding correct synflex tablet uses and safety information matters more than with a simple fever tablet.
Synflex Tablet Uses
Doctors commonly prescribe Synflex for conditions where pain and inflammation occur together. The main synflex tablet uses include:
- Joint and muscle pain: arthritis (osteoarthritis and rheumatoid arthritis), backache, sprains, strains and sports injuries.
- Gout: sudden, severe attacks of gout pain and swelling, usually in the big toe joint.
- Period pain: menstrual cramps (dysmenorrhoea) in women.
- Dental pain: toothache and pain after dental procedures.
- Headache and body pain: including migraine-type headaches in some patients, as directed by a doctor.
- Fever with inflammation: where swelling and pain are the main problems rather than fever alone.

How Synflex Works
When tissue is injured or inflamed, the body produces prostaglandins, which cause pain signals, swelling and redness. Naproxen blocks the COX enzymes that make these prostaglandins. With fewer prostaglandins, pain eases and swelling gradually reduces. Naproxen works more slowly than some painkillers but lasts longer, which is why it is often taken only twice a day and why doctors may prefer it for ongoing inflammatory pain such as arthritis.
Synflex Dosage: General Information
The following is general information found in standard references and product leaflets — the dose your doctor prescribes for you comes first and may differ. Naproxen dosing depends on the condition: arthritis treatment commonly involves divided daily doses, while gout or acute pain may involve a higher first dose followed by lower doses. Tablets are generally swallowed whole with a full glass of water, and taking them with or after food is a standard leaflet instruction to reduce stomach irritation.
General principles that appear in naproxen leaflets include using the lowest effective dose for the shortest necessary time, not exceeding the maximum daily dose stated on the pack, and not combining Synflex with other NSAIDs (such as ibuprofen or diclofenac) unless a doctor specifically advises it. If a dose is missed, leaflets generally advise taking it when remembered unless it is nearly time for the next dose — never double up. Any change in dose or duration is a decision for the prescribing doctor, not the patient.
Side Effects of Synflex
Common side effects
- Stomach pain, heartburn and indigestion
- Nausea, vomiting or diarrhoea
- Headache and dizziness
- Feeling sleepy or light-headed
- Ringing in the ears (tinnitus) in some people
Serious side effects — seek urgent medical care
- Stomach or intestinal bleeding: black stools, vomiting blood, or severe stomach pain
- Allergic reaction: rash, swelling of the face or lips, or difficulty breathing
- Kidney problems: much reduced urination or swelling of the ankles
- Heart and circulation warning signs: chest pain or shortness of breath — naproxen, like other NSAIDs, carries leaflet warnings about cardiovascular risk, especially with long-term high-dose use
Precautions: Who Should Avoid Synflex?
Standard references advise that naproxen may not be suitable for everyone. The following groups are generally told to avoid it or use it only under close medical supervision:
- People with a current or past stomach ulcer or gastrointestinal bleeding
- People allergic to aspirin or other NSAIDs, or who get asthma attacks from them
- People with severe heart, liver or kidney disease
- Women in late pregnancy (NSAIDs are generally avoided in the third trimester)
- People taking blood thinners (such as warfarin), steroids, certain blood pressure medicines or lithium — interactions are well documented in leaflets
- Older adults, who have a higher risk of stomach bleeding with NSAIDs
Alcohol increases the stomach-irritation risk of naproxen, so leaflets advise avoiding it during treatment. Inform your doctor about all medicines and supplements you take before starting an NSAID.
How to Store Synflex
Store Synflex tablets at room temperature, away from moisture, heat and direct sunlight — a closed medicine box in a dry room is suitable in most Pakistani homes. Keep tablets in their original strip until use, check the expiry date printed on the pack, and keep all medicines out of the sight and reach of children. Do not use tablets that are discoloured or past expiry; a pharmacist can advise on safe disposal.
Frequently Asked Questions
What are Synflex tablet uses in Urdu?
سن فلکس ٹیبلٹ (naproxen) درد، سوزش اور بخار کم کرنے کے لیے استعمال ہوتی ہے — In simple words, Synflex is an anti-inflammatory painkiller used for joint pain, muscle pain, gout, period pain and dental pain, as explained in the uses section above.
Is Synflex stronger than paracetamol?
They work differently. Paracetamol mainly reduces pain and fever, while naproxen also reduces inflammation, so doctors often choose Synflex-type medicines where swelling is a major feature, such as arthritis or injury. Which one suits a patient is a medical decision.
Can Synflex be taken on an empty stomach?
Product leaflets generally advise taking naproxen with or after food and with a full glass of water to lower the chance of stomach upset.
How long does Synflex take to work?
Pain relief commonly begins within about an hour of a dose, and the effect lasts longer than many other painkillers, which is why twice-daily dosing is common. Individual response varies.
