Can I take Fenofibrate and Naproxen together?

Guide för läkemedelsinteraktioner

Taking fenofibrate and naproxen together may increase the risk of kidney problems. Both medications can put strain on the kidneys, and using them at the same time can make it harder for your kidneys to filter waste from your blood. In rare cases, this can also lead to a serious muscle condition called rhabdomyolysis, where muscle tissue breaks down and releases substances into the blood that can damage the kidneys further.

Varför detta händer

Fenofibrate and naproxen (an NSAID) are both processed and cleared by the kidneys. Naproxen can reduce blood flow to the kidneys by blocking certain protective chemicals (prostaglandins). When kidney function is slowed down by naproxen, fenofibrate levels can build up in the body, increasing the risk of muscle toxicity and further kidney strain.

Use this combination with caution. If you need to take naproxen for a short time, ensure you stay well-hydrated. If you have pre-existing kidney issues, speak to your doctor before taking naproxen, as they may suggest an alternative like paracetamol. Seek medical advice immediately if you experience unexplained muscle pain, tenderness, weakness, or if your urine becomes very dark in colour.

Astma

Do not take naproxen if you have asthma and have ever had a reaction (like wheezing or shortness of breath) to aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs). It can trigger a severe, life-threatening asthma attack.

Stomach ulcers or bleeding

Naproxen significantly increases the risk of stomach ulcers and internal bleeding. Seek immediate medical help if you pass black, tarry stools or vomit blood. Risk is higher if you are over 65 or take blood thinners.

Muscle pain or weakness - fenofibrate

Contact your doctor immediately if you experience unexplained muscle pain, tenderness, or weakness. This can rarely lead to serious kidney problems. The risk is higher if you also take a 'statin' medicine.

Gallstones or gallbladder disease

Do not take fenofibrate if you have gallbladder disease or a history of gallstones, as fenofibrate can increase the risk of developing stones.

Severe kidney or liver disease

Fenofibrate must not be used if you have severe kidney or liver problems.

Pregnancy (third trimester)

Do not take naproxen if you are more than 20 weeks pregnant. It can cause serious heart or kidney problems in the unborn baby and lead to complications during delivery.

Alkohol

It is best to avoid or strictly limit alcohol when taking fenofibrate. Fenofibrate is used to lower fats (lipids) in the blood, and drinking alcohol can increase your triglyceride levels, making the medicine less effective. Additionally, both alcohol and fenofibrate can put strain on your liver; combining them increases the risk of liver damage.

It is best to avoid or strictly limit alcohol while taking naproxen. Both alcohol and naproxen can irritate the lining of your stomach; combining them significantly increases your risk of developing stomach ulcers or internal bleeding.

Fettrika måltider

The way you take fenofibrate depends on the specific brand and formulation you have been prescribed. Some versions (such as standard tablets or capsules) must be taken with food to help the body absorb the medicine properly. Other versions (such as 'micronised' or 'supracontin' tablets) can be taken with or without food. Check your patient information leaflet or ask your pharmacist which type you have.

Food (General)

You should take naproxen with or just after a meal or a snack. This helps to protect your stomach lining and reduces the risk of indigestion and stomach pain.
