Varför detta händer
Doxadura is an alpha-blocker used to lower blood pressure and treat prostate issues. Garlic supplements have natural blood-pressure-lowering properties. When used together, their effects can add up (an additive effect), causing an excessive drop in blood pressure.

Viktiga försiktighetsåtgärder
Tillbaka till innehållFirst-dose hypotension
Doxadura can cause a sudden drop in blood pressure, especially after the very first dose. This may make you feel dizzy or faint when standing up. It is recommended to take your first dose at bedtime to avoid falls.
Kirurgi
Both garlic supplements and Doxadura can increase the risk of bleeding or affect blood pressure during surgery. You must stop taking garlic supplements at least two weeks before any planned surgical or dental procedure.
Cataract surgery
If you are due to have eye surgery for cataracts, you must tell your surgeon you are taking Doxadura. It can cause a complication called 'Floppy Iris Syndrome' which the surgeon needs to prepare for.

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.
