Taking naproxen and Uribel together may increase the risk of stomach irritation or ulcers. Additionally, Uribel contains a mild salicylate (similar to aspirin), which can increase the risk of bleeding when combined with an anti-inflammatory like naproxen. There is also a small risk that the ingredients in Uribel could affect how your kidneys handle naproxen.

Why this happens
Naproxen is an NSAID that can irritate the stomach lining and affect kidney function. Uribel contains phenyl salicylate; because both drugs inhibit prostaglandins (chemicals that protect the stomach and support kidney blood flow), their effects can add together, increasing the risk of side effects like stomach pain or reduced kidney clearance.
What you should do
Use this combination with caution. If you have a history of stomach ulcers, kidney problems, or asthma, speak to your doctor before taking them together. Take these medications with food to protect your stomach. If you notice any unusual bruising, black tarry stools, or persistent stomach pain, stop taking them and contact your doctor immediately.

Important precautions
Asthma or Aspirin Sensitivity
Do not take this medicine if you have asthma or a history of allergic reactions to aspirin or other NSAIDs, as it can trigger a life-threatening asthma attack or severe allergic reaction.
Stomach Ulcers or Bleeding
This medicine significantly increases the risk of stomach ulcers and internal bleeding. Seek immediate medical help if you experience black, tarry stools or vomit blood.
Glaucoma or Urinary Retention
This medicine can dangerously increase eye pressure in people with glaucoma and worsen symptoms of an enlarged prostate or bladder obstruction.
Food and drink warnings
Alcohol
Drinking alcohol while taking naproxen can increase the risk of stomach irritation, stomach ulcers, and internal bleeding. It is best to limit or avoid alcohol.
Food (General)
Naproxen should ideally be taken with or just after food or a glass of milk. This helps to protect your stomach lining and reduce the risk of indigestion or stomach pain.
Acidic foods and drinks (e.g., citrus fruits, cranberry juice, fizzy drinks)
Uribel works best when the urine is slightly acidic. However, very acidic foods or drinks can sometimes worsen the bladder irritation you are treating. Additionally, some components of Uribel (like methenamine) require a specific urine pH to work effectively; consult your pharmacist before significantly changing your intake of acidic juices.
