Varför detta händer

Lactulose is a laxative that works locally in the bowel and is not absorbed into the bloodstream. Pregabalin is absorbed into the blood to work on the nervous system and is cleared by the kidneys. Because they work in different ways and do not interfere with how the body processes each other, no interaction occurs.

You can continue to take both medicines as prescribed. However, be aware that pregabalin can sometimes cause constipation as a side effect; if your constipation does not improve while using lactulose, you should speak with your doctor or pharmacist.

Mental health disorders

Pregabalin can cause suicidal thoughts or an urge to self-harm. You must seek medical help immediately if your mood changes or you have thoughts of hurting yourself.

Graviditet

Pregabalin use during the first three months of pregnancy may increase the risk of birth defects. Effective contraception must be used during treatment.

Respiratory depression

Pregabalin can cause severe breathing problems, especially if you already have lung disease or if you take it with other medicines that cause drowsiness or contain opioids.

Drug dependence and withdrawal

Pregabalin can lead to dependence and addiction. Do not stop taking this medicine suddenly, as this can cause serious withdrawal symptoms such as seizures, anxiety, and insomnia. Your dose must be reduced gradually.

Galactosaemia

You must not take lactulose if you have galactosaemia, a rare genetic disorder where your body cannot process galactose.

Diabetes

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

Alkohol

It is best to avoid or strictly limit alcohol while taking pregabalin. Combining alcohol with this medicine can significantly increase the risk of side effects such as extreme sleepiness, dizziness, and breathing difficulties.

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 essential to drink plenty of fluids (such as water) while taking lactulose. This medicine works by drawing water into the bowel to soften stools; if you do not drink enough, the medicine may not work effectively and you may become dehydrated.
