Varför detta händer

Both medicines work by slowing down activity in the central nervous system. When used together, their sedative effects add up (an additive effect), making the side effects much stronger than if you took either medicine alone.

Use this combination with caution. Do not drive, cycle, or operate heavy machinery until you know how these medicines affect you. Avoid drinking alcohol, as it will make the sleepiness much worse. If you feel extremely drowsy or have trouble breathing, seek medical help immediately. Your doctor may need to adjust your doses.

Suicidal thoughts and mood changes

Both medicines can increase the risk of suicidal thoughts or self-harm, particularly when first starting treatment or changing doses. Seek immediate medical help if your mood changes or you feel depressed.

Central Nervous System Depression

Both medicines cause significant drowsiness. Combining them, or taking them with alcohol, greatly increases the risk of severe sedation and breathing difficulties. Do not drive or operate machinery until you know how they affect you.

Heart Conditions

Amitriptyline can affect your heart rhythm. It must be used with extreme caution if you have a history of heart disease, a recent heart attack, or an irregular heartbeat.

Graviditet

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

Drug Dependency and Withdrawal

Pregabalin carries a risk of dependence and misuse. Do not stop taking it suddenly, as this can cause serious withdrawal symptoms such as seizures; the dose must be reduced gradually.

Alkohol

You should avoid or strictly limit alcohol while taking these medicines. Both amitriptyline and pregabalin cause drowsiness and dizziness; alcohol significantly increases these effects, which can lead to dangerous levels of sedation, impaired coordination, and breathing difficulties.

Caffeine (Coffee, Tea, Energy Drinks)

Amitriptyline can sometimes cause a fast or irregular heartbeat. High amounts of caffeine can worsen these side effects and may also interfere with the sedative effect of the medicine if you are taking it to help with sleep.
