Simidon – Simvastatin uses, dose and side effects


10 mg, 20 mg, 40 mg film-coated tablets

What Simidon is and what it is used for

Simidone contains the active substance simvastatin and belongs to a group of medicines called statins. These drugs work by reducing the amount of total cholesterol, the “bad” cholesterol ( LDL – cholesterol ), and certain fats called triglycerides in the blood. Simidon also increases the levels of the “good” cholesterol ( HDL – cholesterol ). You should continue with a cholesterol-lowering diet while you are taking this medicine.

Cholesterol is one of several fats found in your blood. Your total cholesterol consists mainly of LDL and HDL cholesterol.

LDL cholesterol is often called the “bad” cholesterol because it causes fat storage in your vessel walls and forms plaque. This plaque storage can eventually lead to a narrowing of your vessels. This narrowing can reduce or block blood flow to important organs such as the heart and brain. Blockage of blood flow can result in a heart attack or stroke.

HDL cholesterol is often called the “good” cholesterol because it helps prevent the “bad” cholesterol from being stored in vessels and protects against heart disease.

Triglycerides are another type of fat in the blood that can increase the risk of heart disease.

Simidone is used for:

  • to lower cholesterol and triglyceride levels in the blood when a low-fat diet and other measures (eg exercise, weight loss) do not give the desired result (primary hypercholesterolemia or combined hyperlipidemia ).
  • to lower hereditary levels of high cholesterol in the blood ( homozygous familial hypercholesterolemia ), in addition to diet and other treatments (eg LDL -apheresis), or when such treatments are not appropriate.
  • to reduce the risk of coronary heart disease if you have atherosclerosis ( arteriosclerosis ) or diabetes, even if your cholesterol levels are normal, as a supplement to your diet and other treatments.

In most people, high cholesterol does not cause immediate symptoms. Your doctor can measure your cholesterol level with a simple blood test. Visit your doctor regularly, monitor your cholesterol levels, and discuss your goals with your doctor.

Simvastatin contained in Simidon may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

Warnings and cautions

Talk to your doctor or pharmacist before taking Simidon.

Tell your doctor:

  • about all your medical ailments, including allergies.
  • if you have high alcohol consumption.
  • if you have or have had a history of liver disease. Simidon may not be the right medicine for you.
  • if you are going to have surgery. Treatment interruption with Simidon may need to be done for a short time.
  • If you are of Asian descent, then another dose may apply to you.
  • if you are taking or in the last 7 days have taken a medicine called fusidic acid (used to treat bacterial infections ) either by mouth or by injection. The combination of fusidic acid and Simidone can lead to serious muscle problems ( rhabdomyolysis ).

Your doctor should take a blood sample before you start taking Simidon, and if you have any symptoms of liver problems during treatment with Simidon. This blood test is taken to check your liver function.

Your doctor may also need to take a blood test to check your liver function after you start taking Simidon.

During treatment with this medicine, your doctor will closely monitor you if you have diabetes or are at risk of developing diabetes. You are more likely to be at risk for diabetes if you have high blood sugar and blood fat levels, are overweight, and have high blood pressure.

Tell your doctor if you have any serious lung disease.

Tell your doctor or pharmacist if you have persistent muscle weakness. 

Additional tests and medications may be needed to investigate and treat this.

Contact a doctor immediately if you experience unexplained muscle pain, sensitivity to pressure, or muscle weakness. The reason for this is that in rare cases, muscle problems can be serious and involve the breakdown of muscles with kidney damage as a result and in very rare cases, deaths have occurred.

The risk of muscle breakdown may be greater for you with high doses of Simidon, especially with a dose of 80 mg. The risk of muscle breakdown is also greater in some patients. Talk to your doctor if any of the following apply to you:

  • you are over 65 years old
  • you have kidney problems
  • you have thyroid problems
  • you or close family members have a hereditary muscle disease
  • you are a woman
