Taking Reishi mushroom alongside atorvastatin may increase the risk of side effects, particularly those affecting the liver or muscles.

Why this happens
Both atorvastatin and Reishi mushroom are processed by the liver. Reishi contains compounds that may interfere with the liver enzymes (specifically CYP450 enzymes) responsible for breaking down atorvastatin.

Additionally, both substances can individually affect liver function, potentially leading to an additive effect on liver enzymes.
What you should do
You should consult your doctor or pharmacist before combining Reishi mushroom with atorvastatin. If you decide to take both, be alert for signs of liver issues (such as yellowing of the eyes or skin, dark urine, or upper stomach pain) or unexplained muscle pain, tenderness, or weakness. Your doctor may wish to monitor your liver function more closely through routine blood tests.

Treatment and medication
Can I take Apixaban and Naproxen together?
Taking apixaban and naproxen together significantly increases your risk of serious bleeding. This includes internal bleeding, such as in the stomach or brain, which can be life-threatening. Signs to watch for include coughing up blood, vomit that looks like coffee grounds, black or tarry stools, or bruising that happens very easily.

Treatment and medication
Can I take Iron and Levothyroxine together?
Taking iron supplements at the same time as levothyroxine can significantly reduce the amount of thyroid hormone your body absorbs. This can lead to an underactive thyroid (hypothyroidism), causing symptoms like tiredness, weight gain, feeling cold, and dry skin.
