Por que isso acontece
Vitamin B2 and Vitamin C are both water-soluble vitamins that are processed by the body in different ways. They do not compete for absorption in the gut, nor do they interfere with how each other is broken down or removed from the body. They have complementary roles in supporting the immune system and energy production.

Precauções importantes
Voltar ao conteúdoCálculos renais (oxalato)
High doses of vitamin C can increase the amount of oxalate in your urine, which significantly raises the risk of developing kidney stones, especially if you have had them before.

If you have a G6PD deficiency (a genetic enzyme condition), high doses of vitamin C can cause your red blood cells to break down (haemolysis).

It is best to avoid or strictly limit alcohol when taking these vitamins. Alcohol can interfere with the absorption of Vitamin B2 and Vitamin C in the gut and increases the rate at which your body flushes them out, making the supplements less effective. Combining alcohol with any medicine also increases the risk of liver strain.

Can I take Lisinopril and Potassium together?
Taking lisinopril and potassium supplements together can cause the levels of potassium in your blood to become dangerously high (a condition called hyperkalaemia). While your body needs potassium for your heart and muscles to work, too much of it can lead to serious heart rhythm problems or even cause the heart to stop. Symptoms of high potassium can include muscle weakness, tingling sensations, or palpitations, but often there are no symptoms until the level is very high.

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.
