Taking amlodipine and citalopram together may increase the risk of developing an abnormal heart rhythm. While both are commonly prescribed together, they can both affect the electrical activity of your heart. In rare cases, this can lead to a serious condition called QT prolongation, where the heart muscle takes longer than normal to recharge between beats. This can cause palpitations, dizziness, or fainting.

Why this happens
Both medications have the potential to affect the 'QT interval' (the electrical timing of the heart). Citalopram is known to cause this effect, especially at higher doses, and amlodipine may occasionally contribute to this or change how the heart responds to electrical signals.
What you should do
For most people, this combination is safe, but you should use caution. Ensure your doctor knows you are taking both. Seek medical help immediately if you feel a sudden fast or pounding heartbeat, severe dizziness, or if you faint. Your doctor may occasionally want to check your heart rhythm with an ECG (heart trace) or monitor your salt levels (electrolytes) through blood tests.

Can I take Ibuprofen gel 10% and Shortec together?
Using ibuprofen gel alongside Shortec (oxycodone) is generally safe, but there is a small risk of increased side effects such as drowsiness, dizziness, or stomach irritation if the ibuprofen is absorbed into the bloodstream in significant amounts.

Can I take Citalopram and Co codamol together?
Taking these two medicines together can increase the risk of a rare but serious condition called serotonin syndrome. It can also make you feel more drowsy or dizzy than usual. Additionally, citalopram may slightly reduce how well the codeine part of the co-codamol works to relieve your pain.
