Patient picks for Drug interactions
Treatment and medication
Can I take Acetaminophen and Levocetirizine together?
Taking paracetamol (acetaminophen) and levocetirizine together is generally considered safe. There are no known major interactions between these two medicines. However, both can occasionally cause drowsiness or tiredness in some people. If you experience these side effects, they may be slightly more noticeable when taking both medicines at the same time.
Treatment and medication
Can I take Atorvastatin and Magnesium together?
Taking magnesium antacids at the same time as atorvastatin can lower the amount of the statin medicine that your body absorbs. This might make your cholesterol treatment less effective.
