Brief Answer:
Can produce serious side effect

Detailed Answer:
Hello,

Welcome and thanks for your query.
Diltiazem increases the level and effect of Simvastatin by its effect on liver and intestinal enzymes. Therefore the side effects of Simvastatin will be more and it is not advisable to take a high dose of simvastatin and diltiazem CD together.

Do get back to me if you have more queries.

take care,

Dr XXXXXXX

My daily Simvastatin dose is only 20 mg. At this relatively low level is 120 mg of Dilitiazem daily still a problem?
