Simvastatin-Odan: Uses, Side Effects and Dosage

What the medication is used for:

Your physician has prescribed SIMVASTATIN-ODAN to lower the levels of cholesterol and fatty substances called triglycerides in your blood and to reduce the health risks associated with Coronary Heart Disease (CHD).

Elevated cholesterol can cause CHD by clogging the blood vessels (atherosclerosis) that carry oxygen and nutrients to the heart.

If you have CHD or other signs of atherosclerosis such as previous stroke, symptoms of peripheral vascular disease, or diabetes (regardless of the amount of cholesterol in your blood),

SIMVASTATIN-ODAN should lessen the risk of heart attack or stroke.

You can also benefit from taking SIMVASTATIN-ODAN if you have high levels of cholesterol with or without associated high triglycerides (primary hypercholesterolemia, or combined hyperlipidemia)

and homozygous familial hypercholesterolemia (high cholesterol inherited from both parents).

As part of your treatment plan to lower cholesterol, and depending on your health and lifestyle, your physician may recommend a diet to reduce cholesterol and other measures such as exercise and weight control.

What it does:

Simvastatin is one of the class of medicines known as HMG-CoA reductase inhibitors. They inhibit, in other words block, an enzyme that is necessary for the body to make cholesterol. In this way, less cholesterol is produced in the liver. Medicines like this one are prescribed along with, and not as a substitute for, a special diet and other measures. Simvastatin is used to lower the levels of cholesterol [particularly low-density lipoprotein cholesterol (LDL-C)] and fatty substances called triglycerides in your blood.

SIMVASTATIN-ODAN reduces the amount of cholesterol in your blood. Elevated cholesterol can cause CHD by clogging the blood vessels that carry oxygen and nutrients to the heart.

When it should not be used:

Do not take SIMVASTATIN-ODAN if you are:

• allergic to any of its components
• diagnosed with active liver disease

• pregnant or breast-feeding

Before taking SIMVASTATIN-ODAN, tell your physician or pharmacist if you:

• are pregnant, intend to become pregnant, are

  breast-feeding or intend to breast-feed

• have thyroid problems

• regularly drink three or more alcoholic

  drinks daily

• are taking any other cholesterol lowering

  medication such as fibrates (gemfibrozil, fenofibrate), niacin or ezetimibe

• are taking any other medications, including

  prescription, nonprescription and natural health products as drug interactions are possible

• have a family history of muscular disorders

• had any past problems with the muscles

  (pain, tenderness), after using an HMG-CoA reductase inhibitor (“statin”) such as atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (MEVACOR^®), pravastatin (Pravachol) or rosuvastatin (Crestor), or have developed an allergy or intolerance to them

• have kidney or liver problems
• have diabetes

• have undergone surgery or other tissue

  injury

• do excessive physical exercise

• are of childbearing age. Cholesterol

  compounds are essential elements for the development of a fetus. Cholesterol-lowering drugs can harm the fetus. If you are of childbearing age, discuss with your physician the potential hazards to the fetus and the importance of birth control methods.

• become pregnant. SIMVASTATIN-ODAN

  should not be used by pregnant women. If you become pregnant, discontinue use immediately and discuss with your physician.

  You should tell your physician about all drugs that you are using or plan to use, including those obtained without a prescription, while taking SIMVASTATIN-ODAN. You should also tell any physician who is prescribing a new medication for you that you are taking SIMVASTATIN-ODAN.

  Because taking SIMVASTATIN-ODAN with any of the following drugs can increase the risk of muscle problems (see Side effects of this medicine - and what you should do), it is particularly important to tell your physician if you are taking:

  • cyclosporine (immunosuppressant)
  • danazol
  • antifungal agents (such as itraconazole or ketoconazole)
  • fibrates/fibric acid derivatives (bezafibrate and gemfibrozil) (drug to treat lipids problems)
  • the antibiotics (erythromycin, clarithromycin, telithromycin, and fusidic acid [oral or intravenous])
  • HIV protease inhibitors (such as indinavir, nelfinavir, ritonavir and saquinavir)
  • the antidepressant nefazodone
  • amiodarone (a drug used to treat an irregular heartbeat)
  • verapamil or diltiazem or amlodipine (drugs used to treat high blood pressure, angina, or other heart conditions)

It is also important to tell your doctor if you are taking corticosteroids, anticoagulants (drug that prevents blood clots, such as warfarin), digoxin (a drug used to treat heart problems), niacin, or fenofibrate, another fibric acid derivative. Also tell your doctor if you are taking niacin or a niacin-containing product and are Chinese.

Usual Dose:

• Take your medication exactly as your

physician instructed. Do not change the

• dose unless directed by a physician. It is

  usually recommended as a single dose with the evening meal. For adults, your physician may adjust your dose to a maximum of 80 mg a day, given as a single dose in the evening. The 80-mg dose is only for patients who have not reached their cholesterol goal on the 40-mg dose. It is important to continue taking the tablets as instructed. Do not alter the dosage or stop taking the medicine without consulting your physician.

• Carefully follow any measures that your

  physician has recommended for diet, exercise or weight control.

• When taking SIMVASTATIN-ODAN, you

  should avoid consuming very large amounts (over 1 liter daily) of grapefruit juice; however, typical consumption (one 250 mL glass daily) is unlikely to cause any problems.

• When taking SIMVASTATIN-ODAN

  concurrently with cholestyramine or any other resin, an interval of at least two hours should be maintained between the two drugs.

• Keep your appointments regularly with your

  physician so that your blood can be tested and your progress checked at proper intervals.

• Avoid drinking large quantities of alcohol.

• Do not start taking any other medicines

  unless you have discussed the matter with your physician or pharmacist.

• Let your physician know if you suffer a

  severe injury, or severe infection.

• If you have to undergo any kind of surgery,

  tell your physician about the planned surgery; and also inform the physician in charge that you are taking this medicine.

Overdose:

Contact your physician immediately.

In case of drug overdosage, contact a health care practitioner, hospital emergency department or original Poison Control Center immediately, even if there are no symptoms.

Missed Dose:

If you miss taking a tablet at its usual time, take it as soon as possible. But, if it is too close to the time of your next dose: take only the prescribed dose at the appointed time. Do not take a double dose.

Along with its intended action, any medication may cause unwanted effects. Most people do not have any problem when taking this medicine; but if you notice any of the following reactions, check with your physician as soon as possible:

Fever

Blurred vision

Muscle effects

Liver problems (sometimes serious) (See SERIOUS SIDE EFFECTS, HOW OFTEN THEY HAPPEN AND WHAT TO DO ABOUT THEM.)

Some other side effects that may occur, generally do not require medical attention, and may come and go during treatment. But if any of the following persist or become troublesome, do check with your physician or pharmacist:

Constipation, diarrhea, gas, stomach upset, nausea Pain in the abdomen

Headache

Skin rash

Memory loss

Trouble sleeping

Depression

Erectile dysfunction

Breathing problems including persistent cough and/or shortness of breath or fever

Side effects such as myalgia (muscle pain), myopathy (muscle disease with aching or weakness), rhabdomyolysis (a muscle wasting disease), associated tenderness, and rare cases of

rhabdomyolysis leading to kidney failure have been reported with other drugs of this class, known as HMG-CoA reductase inhibitors (“statins”), including simvastatin. This risk of muscle breakdown is greater for patients taking higher doses of simvastatin. This risk of muscle breakdown is greater for older patient (65 years of age and older), female patients, patients with abnormal kidney function and patients with thyroid problems.

As these muscle problems are on rare occasions serious, you should contact your physician promptly if you experience any of the following:

• muscle pain that you cannot explain
• muscle tenderness or muscle weakness

• generalized weakness, especially if you do

  not feel well (i.e., fever or fatigue)

• brownish or discoloured urine

This is not a complete list of side effects. For any unexpected effects while taking SIMVASTATIN-ODAN, contact your physician or pharmacist.

Store your tablets at room temperature (15^oC - 30^oC), in the original package, away from heat and direct light, and out of damp places, such as the bathroom or kitchen.

Keep all medicines out of the reach of children. Do not use outdated medicine.
