Can I take Furosemide and Joint assurance together?

Why this happens

Glucosamine and chondroitin (found in Joint Assurance) can enhance the effects of blood-thinning medications. While they do not directly change how furosemide works in the body, the combination can occasionally lead to changes in blood sugar or blood pressure stability in sensitive individuals.

You may be experiencing an interaction between furosemide and joint assurance if:

• You feel dizzy or lightheaded, particularly when standing up.

• You notice increased tiredness or weakness.

• You develop muscle cramps or muscle weakness, which may be linked to electrolyte changes.

• You experience changes in swelling in your legs or joints.

• You notice digestive symptoms, such as nausea or stomach upset.

• Blood tests show changes in kidney function or electrolyte levels.

• Symptoms start after starting the supplement or changing the dose while taking furosemide.
  

It is generally safe to take these together, but you should monitor your blood pressure regularly. If you notice any unusual bruising, bleeding, or a significant change in your blood sugar levels, speak to your GP or pharmacist.

If you have any of the above symptoms, you should:

• Contact your GP or pharmacist for advice as soon as possible.

• Do not stop taking furosemide suddenly unless advised by a healthcare professional.

• Avoid starting, stopping, or changing Joint Assurance or other supplements without medical advice.

• Seek urgent medical help if you experience severe dizziness, confusion, or muscle weakness.

• Attend any blood tests arranged to check kidney function or electrolyte levels.

Dehydration and low blood pressure

Furosemide is a potent diuretic. You must not take it if you are already severely dehydrated or cannot pass urine. It can cause a rapid drop in blood pressure and salt levels, especially if you are also taking other blood pressure medicines.

Gout

Furosemide can increase the levels of uric acid in your blood, which may trigger a painful gout attack or make existing gout worse.

Sulphonamide Allergy

If you have a known allergy to sulphonamide antibiotics (such as sulfamethoxazole), you may also be allergic to furosemide. You must inform your healthcare provider before taking this medicine.

Shellfish Allergy

Many joint supplements are derived from the shells of crustaceans. If you have a shellfish allergy, taking Joint Assurance could trigger a severe allergic reaction (anaphylaxis).

Diabetes

Glucosamine may affect blood sugar levels. Monitor your blood glucose more closely when starting or changing your dose.

Warfarin therapy

Glucosamine can significantly increase the blood-thinning effect of warfarin, increasing your risk of serious bleeding. Consult your doctor before use.

Alcohol

It is best to avoid or strictly limit alcohol while taking furosemide. Alcohol can increase the blood-pressure-lowering effect of this medicine, which may make you feel dizzy, light-headed, or faint, especially when standing up. Both alcohol and furosemide are diuretics, which increases the risk of dehydration.

Liquorice (Natural) / Liquorice Root

Avoid eating large amounts of natural liquorice or taking liquorice root supplements. Natural liquorice can cause the body to lose potassium and retain salt, which opposes the action of furosemide and can lead to dangerously low potassium levels.

Caffeine (Coffee, Tea, Energy Drinks)

Limit your intake of caffeine. Caffeine is a mild diuretic and can increase the water-loss effect of furosemide, potentially increasing the risk of dehydration or electrolyte imbalances.
