What is lovastatin?
Lovastatin is used together with diet to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL), to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood).
Lovastatin may also be used for purposes not listed in this medication guide.
You should not take lovastatin if you have active liver disease, or if you are pregnant or breastfeeding.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.
Stop taking lovastatin and tell your doctor at once if you become pregnant.
Before taking this medicine
You should not use lovastatin if you are allergic to it, or if:
you are pregnant or breastfeeding; or
you have active liver disease.
Many drugs can interact and cause dangerous effects. Some drugs should not be used together with lovastatin. Your doctor may change your treatment plan if you also use:

Tell your doctor if you have ever had:

Swallow the tablet whole and do not crush, chew, or break it.
It may take up to 4 weeks before your cholesterol levels improve, and you may need frequent blood tests. Even if you have no symptoms, tests can help your doctor determine if lovastatin is effective.
You may need to stop using lovastatin for a short time if you have surgery or a medical emergency. Do not stop taking this medicine unless your doctor tells you to.
Lovastatin is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow your doctor's instructions very closely.
