Taking magnesium (especially as an antacid) at the same time as solifenacin may slow down how quickly your body absorbs the solifenacin. This could potentially delay how well the medicine works for your bladder symptoms. Additionally, both substances can affect how your bowels work; solifenacin often causes constipation, while some forms of magnesium can cause diarrhoea or, conversely, certain antacids can worsen constipation.

Why this happens
Magnesium-containing antacids can increase the pH level in the stomach and physically bind to other drugs, which slows down the rate at which solifenacin enters the bloodstream. There is also a minor 'pharmacodynamic' overlap where both drugs affect the digestive system in opposite or unpredictable ways.
What you should do
You can usually take both, but it is best to space them out. Try to take your solifenacin at least 2 hours before or 4 to 6 hours after taking a magnesium supplement or antacid. If you notice your bladder symptoms are not being controlled as well as usual, or if you suffer from severe constipation, speak with your pharmacist or doctor.

Taking indapamide and ramipril together can cause your blood pressure to drop too low, especially when you first start the combination. This can make you feel dizzy, lightheaded, or faint. It can also put extra strain on your kidneys.

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.
