Atorvastatin is usually taken once a day, or with or without food. The tablet should be taken whole with water. The fixed dose of this medication must not be changed without medical consultation with a healthcare provider.

As a rule, atorvastatin is administered:

Initial dose: A usually prescribed amount for most patients is once daily 10 mg to 20 mg.

Dose titration: Depending on the cholesterol results, a more effective dose can be titrated upward, typically in increments of 10 mg to 20 mg at intervals of every 2 to 4 weeks.

Typical dose: For most patients, a typical dose is 20 to 40 mg per day, but ranges between 10 to 80 mg/day.

Maximum dose: The maximum dose recommended of atorvastatin is 80 mg/day.

Take atorvastatin at the same time every day. Its dosing should not be restricted to the consumption of food or without any food, but could be taken in the evening or nighttime as the production rate of cholesterol in the liver is higher during nighttime.

This drug, apart from reducing the LDL cholesterol, can also do the following:

Elevate HDL cholesterol: Atorvastatin can facilitate the removal of cholesterol from the blood, and by doing that, it increases HDL cholesterol levels protecting the arteries

Reduce triglycerides: It reduces the levels of triglycerides, that is the other type of fat in the blood. When their levels start accumulating, it ends up increasing the chances of cardiovascular-related problems.

Stabilize existing plaques: Atorvastatin stabilizes plaques already existing in the arteries, thereby preventing them from bursting open to cause life-threatening blood clots.

Generally, atorvastatin is tolerated well by the body, but like most drugs, atorvastatin has several side effects. Some of the major side effects include:

Myopathy: Muscle Pain or Weakness – A common side effect associated with atorvastatin is muscle pain, tenderness, or weakness. However, in some patients, this could advance to rhabdomyolysis, a serious condition that may ultimately result in muscle breakdown and damage to the kidneys.

Abnormal Liver Enzymes: Atorvastatin causes abnormal elevations in liver enzymes and potentially shows liver damage. This is a transient effect that, after stopping the medicine, may regain normal values; over time, monitoring is required with repeated liver function tests.

Digestive System Disorder: Some patients will experience nausea, constipation, diarrhea, or abdominal pain when administered atorvastatin.

Tiredness: A few patients will become tired or weak during treatment using atorvastatin.

Headache: Headache is one of the most common side effects of the atorvastatin.

Liver Disease: Patients with liver disease or abnormal results in liver function tests should exercise caution when using atorvastatin. Liver enzymes should be monitored at regular intervals during therapy.

Muscle Pain or Weakness. If you experience muscle pain, tenderness, or weakness that cannot be accounted for by a medical condition, you must notify your doctor right away, which can be myopathy or rhabdomyolysis.

Pregnancy and Breastfeeding. Atorvastatin should not be administered during pregnancy and breastfeeding as it can cause damage to the fetus or infant during those stages. Women of childbearing age taking treatment with atorvastatin must use effective contraception.

Interactions with Other Medications: Atorvastatin interacts with a number of other drugs such as some antifungals, antibiotics, HIV drugs and immunosuppressants. 

Grapefruit – Grapefruit can increase Atorvastatin levels in the blood, raising the risk of serious side effects like muscle damage.

Clarithromycin – This antibiotic can increase Atorvastatin’s concentration in your body, which may increase the risk of side effects, especially muscle-related issues.

Cyclosporine – Cyclosporine, used for immune suppression, can raise Atorvastatin levels, leading to an increased risk of muscle pain and liver problems.

Gemfibrozil – Taking Gemfibrozil with Atorvastatin may increase the risk of muscle damage and other serious side effects.

A professional should be consulted to determine appropriate dosage of atorvastatin that will help based on your cholesterol levels and medical history. The common range for an initial dose is between 10–20 mg once a day. Maintenance: 20–80 mg once daily. Maximum: 80 mg per day. Your physician will monitor your cholesterol levels. Regular follow-up appointments and blood tests are necessary to see the response and to rule out any side effects.

Atorvastatin is a prescription-only drug, therefore it can only be prescribed by a doctor. A physician will assess the cholesterol levels and heart health and risk factors for cardiovascular disease before prescribing the atorvastatin. Regular blood tests and check-ups are significant to determine that the medication is working adequately and safely.
