Why this happens
Both medications can have an effect on the cardiovascular system. Amlodipine works by relaxing blood vessels to lower blood pressure. Sertraline, while primarily an antidepressant, can occasionally influence heart rhythm or slightly enhance the blood-pressure-lowering effects of other drugs. Additionally, both drugs are processed by the liver, which can sometimes lead to slightly higher levels of the medication in your bloodstream.
What you should do
Back to contentsIt is generally safe to take these together, but you should monitor your blood pressure regularly. To avoid dizziness, try to get up slowly from a sitting or lying position. If you feel very dizzy, experience a racing heartbeat, or faint, contact your GP. Do not stop taking either medication without consulting your doctor first.

Important precautions
Back to contentsBleeding risk
Sertraline increases your risk of bleeding. You must be extremely cautious if you take blood-thinning medicines (like warfarin) or regular anti-inflammatory painkillers (like ibuprofen or aspirin).
Low sodium (Hyponatremia)
Sertraline can cause a serious drop in sodium levels, especially in the elderly. Seek medical help if you experience sudden confusion, severe headaches, or weakness.
