Drug & Food Interactions of Synflex 550mg Tablet

Drug Interactions:

• Anticoagulants (e.g., Warfarin, Heparin) — Naproxen may enhance the blood-thinning effect, increasing the risk of bleeding

• Antihypertensive medications (e.g., ACE inhibitors, ARBs, Beta-blockers) — NSAIDs may reduce the effectiveness of blood pressure-lowering medicines
• Diuretics (water tablets) — Naproxen may reduce the effectiveness of diuretics and increase the risk of kidney-related side effects
• Lithium — Naproxen may increase lithium levels in the blood, potentially leading to toxicity
• Methotrexate — Co-administration may increase Methotrexate toxicity; use with caution
• Selective Serotonin Reuptake Inhibitors (SSRIs) — Combined use may increase the risk of gastrointestinal bleeding
• Corticosteroids (e.g., Prednisolone) — Increased risk of gastrointestinal ulceration and bleeding
• Cyclosporine — May increase the risk of nephrotoxicity (kidney damage)
• Oral hypoglycaemic agents and Insulin — Naproxen may alter blood glucose levels; monitor closely

Food & Lifestyle Interactions:

• Alcohol — Avoid alcohol while taking Synflex 550mg Tablet as it significantly increases the risk of stomach bleeding and liver stress
• High-sodium foods — Since Naproxen Sodium contains sodium, patients on a sodium-restricted diet should be mindful of their overall sodium intake
