Por que isso acontece
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.
O que você deve fazer

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.

Precauções importantes
Voltar ao conteúdoPensamentos suicidas e mudanças de humor
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.
Gravidez
O uso de Pregabalina durante os primeiros três meses de gravidez pode aumentar o risco de defeitos congênitos. Deve-se usar contracepção eficaz durante o tratamento.
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.
Avisos sobre alimentos e bebidas
Voltar ao conteúdoÁlcool
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.
Cafeína (Café, Chá, Bebidas Energéticas)
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.

Can I take Sertraline and Fluoxetine together?
Taking sertraline and fluoxetine together significantly increases the risk of a rare but serious condition called serotonin syndrome. This happens because both medicines work by increasing the level of a chemical called serotonin in your brain. If levels get too high, it can cause symptoms like shivering, diarrhoea, confusion, severe muscle tightness, fever, and even seizures. Additionally, fluoxetine can slow down how your body breaks down sertraline, leading to a build-up of the drug in your system and increasing the risk of side effects.
