Can I take Ibuprofen gel 10% and Lactulose together?

Why this happens

Ibuprofen gel is applied to the skin and acts locally; very little of the medicine enters the bloodstream. Lactulose is a sugar-based laxative that stays mostly in the bowel to soften stools. Because they work in completely different parts of the body and are processed differently, they do not interfere with one another.

What you should do

You can continue to use both medications as directed by your doctor or the product packaging. Always ensure you wash your hands after applying ibuprofen gel to avoid accidental contact with your eyes or mouth.

Important precautions

Asthma

Do not use this gel if you have asthma that is triggered or worsened by aspirin or other NSAIDs, as it can cause a severe allergic reaction or breathing difficulties even when applied to the skin.

Pregnancy (third trimester)

Do not take ibuprofen if you are more than 6 months pregnant, as it can cause serious heart and kidney problems in the unborn baby and complications during birth.

Sunlight exposure

Avoid exposing the treated area to direct sunlight or sunlamps during treatment and for two weeks after stopping, as the gel can make your skin significantly more sensitive to light, leading to severe rashes or burns.

Galactosaemia or bowel obstruction

Do not take lactulose if you have galactosaemia (a rare inability to process galactose) or a complete blockage in your bowel, as it can lead to serious complications.

Diabetes

If you are taking high doses of lactulose for liver disease (portal systemic encephalopathy), the sugar content may affect your blood glucose levels.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while using ibuprofen. Although the amount of medicine absorbed through the skin is low, combining ibuprofen with alcohol can increase the risk of irritation to your stomach lining or, in rare cases, liver strain.

It is best to avoid or strictly limit alcohol when taking lactulose. Alcohol can cause dehydration, which may worsen the constipation you are trying to treat. Additionally, if you are taking lactulose for liver disease (hepatic encephalopathy), alcohol must be avoided entirely as it can significantly worsen your condition.

Water and fluids

It is very important to drink plenty of fluids (6 to 8 glasses a day) while taking lactulose. Without enough water, the medicine may not work as effectively and can cause further constipation.
