Why this happens
Both medicines work by slowing down activity in the central nervous system. When used together, their sedative effects add up (an additive effect), making the side effects much stronger than if you took either medicine alone.
What you should do
Use this combination with caution. Do not drive, cycle, or operate heavy machinery until you know how these medicines affect you. Avoid drinking alcohol, as it will make the sleepiness much worse. If you feel extremely drowsy or have trouble breathing, seek medical help immediately. Your doctor may need to adjust your doses.

Patient picks for Drug interactions

Treatment and medication
Can I take Esomeprazole and Magnesium together?
Taking esomeprazole for a long time (usually more than three months) can lower the levels of magnesium in your blood. This can lead to symptoms like tiredness, muscle spasms, or an irregular heartbeat. Additionally, if you take magnesium as an antacid or supplement at the same time as esomeprazole, it might slightly interfere with how well the medicine is absorbed.

Treatment and medication
Can I take Clarithromycin and Rosuvastatin together?
Taking these two medicines together can significantly increase the amount of rosuvastatin in your blood. This increases the risk of serious muscle damage (rhabdomyolysis), which can lead to kidney problems. Symptoms to watch for include unexplained muscle pain, tenderness, or weakness, especially if you also feel generally unwell or have a fever.
