sitagliptin-simvastatin oral Warnings
sitagliptin-simvastatin oral Uses
This product contains 2 medications: sitagliptin and simvastatin. Sitagliptin is used with a proper diet and exercise program to control high blood sugar in people with type 2 (non-insulin-dependent) diabetes. Sitagliptin works by increasing levels of natural substances called incretins. Incretins help to control blood sugar by increasing insulin release, especially after a meal. They also decrease the amount of sugar your liver makes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke.
Sitagliptin should not be used to treat people with type 1 diabetes (insulin-dependent diabetes).
Simvastatin is used along with a proper diet to help lower "bad" cholesterol and fats (such as LDL, triglycerides) and raise "good" cholesterol (HDL) in the blood. It belongs to a group of drugs known as "statins." It works by reducing the amount of cholesterol made by the liver. Lowering "bad" cholesterol and triglycerides and raising "good" cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks.
In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.How to use sitagliptin-simvastatin oral
Read the Medication Guide provided by your pharmacist before you start using sitagliptin/simvastatin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once daily in the evening.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Chinese patients taking niacin may require lower doses of simvastatin. Ask your doctor for more details.
The usual maximum dose for the simvastatin in this medication is 40 milligrams a day. If you have been instructed by your doctor to take more than 40 milligrams of simvastatin, continue on that same dose. However, promptly talk with him or her about the risks and benefits of your higher dose.
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of serious side effects will increase.
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
Take this medication regularly to get the most benefit from it. Remember to take it at the same time each day. It is important to continue taking this medication even if you feel well.
It is very important to continue to follow your doctor's advice about diet and exercise. For the treatment of high cholesterol/triglycerides, it may take up to 4 weeks before you get the full benefit of this drug.
Tell your doctor if your condition does not improve or if it worsens (such as blood sugar levels remaining high or increasing).
sitagliptin-simvastatin oral Side Effects
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
A very small number of people taking simvastatin may have mild memory problems or confusion. If these rare effects occur, talk to your doctor.
This drug may infrequently cause muscle problems (which can rarely lead to very serious conditions called rhabdomyolysis and autoimmune myopathy). Tell your doctor right away if you develop any of these symptoms during treatment and if these symptoms persist after your doctor stops this drug: muscle pain/tenderness/weakness (especially with fever or unusual tiredness), change in the amount of urine.
This medication may rarely cause liver problems or disease of the pancreas (pancreatitis). If you notice any of the following rare but serious side effects, stop taking this medication and tell your doctor right away: yellowing eyes/skin, dark urine, severe stomach/abdominal pain, persistent nausea/vomiting.
Although sitagliptin by itself usually does not cause low blood sugar (hypoglycemia), low blood sugar may occur if this drug is prescribed with other diabetes medications. Talk with your doctor or pharmacist about whether the dose(s) of your other diabetes medication(s) needs to be lowered. Drinking large quantities of alcohol, not getting enough calories from food, or doing unusually heavy exercise may also lead to low blood sugar. Symptoms may include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, headache, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor immediately about the reaction. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medication(s).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
