The drug comes in three different strengths: 10 mg, 20 mg, and 40 mg. Most adults being treated for high
cholesterol start off with lovastatin 20 mg tablets. Depending on how you respond to the medicine, your healthcare provider may increase or decrease your dosage as needed.
The recommended lovastatin dosage for children ages 10 to 17 with high cholesterol is 10 mg or 20 mg once a day. If lovastatin 20 mg tablets are still not effective in lowering your child's cholesterol, his or her healthcare provider may recommend increasing the dose up to a maximum of 40 mg daily.
