What is a generic medication?
Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication. In other words, generic medications have the same pharmacological effects as their brand-name counterparts. Over half of all prescribed medications are for generic medications.

Metformin ER Overview
Metformin is used with a proper diet and exercise program and possibly with other medications to control high blood sugar. Metformin ER is used in patients with type 2 diabetes. 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. Metformin works by helping to restore your body's proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver makes and that your stomach/intestines absorb.
Metformin ER Warnings
Rarely, too much metformin can build up in the body and cause a serious (sometimes fatal) condition called lactic acidosis. Lactic acidosis is more likely if you are an older adult, if you have kidney or liver disease, dehydration, heart failure, heavy alcohol use, if you have surgery, if you have X-ray or scanning procedures that use iodinated contrast, or if you are using certain drugs. For some conditions, your doctor may tell you to stop taking Metformin ER for a short time. Ask your doctor or pharmacist for more details. Stop taking Metformin ER and get medical help right away if you have any symptoms of lactic acidosis, such as unusual tiredness, dizziness, severe drowsiness, chills, blue/cold skin, muscle pain, fast/difficult breathing, slow/irregular heartbeat, or stomach pain with nausea/vomiting/diarrhea.
How to Use Metformin ER
Read the Patient Information Leaflet if available from your pharmacist before you start taking metformin and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take Metformin ER by mouth as directed by your doctor, usually once daily with the evening meal. Drink plenty of fluids while taking Metformin ER unless otherwise directed by your doctor. Do not crush or chew Metformin ER. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. The Dosage of Metformin ER 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). To reduce your risk of side effects (such as upset stomach), your doctor may direct you to start Metformin ER at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Take Metformin ER regularly in order to get the most benefit from it. Remember to use Metformin ER at the same time each day. If you are already taking another diabetes drug (such as chlorpropamide), follow your doctor's directions carefully for stopping/continuing the old drug and starting metformin. Check your blood sugar regularly as directed by your doctor. Keep track of the results, and share them with your doctor. Tell your doctor if your blood sugar measurements are too high or too low. Your dosage/treatment may need to be changed.
Metformin ER Precautions
Before taking Metformin ER, tell your doctor or pharmacist if you are allergic to metformin; or if you have any other allergies. Metformin ER may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using Metformin ER, tell your doctor or pharmacist your medical history,severe breathing problems (such as obstructive lung disease, severe asthma), blood problems (such as anemia, vitamin B12 deficiency), kidney disease, liver disease. Before having surgery or any X-ray/scanning procedure using iodinated contrast, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). You may need to stop Metformin ER for a short time for the surgery/procedure. Ask your doctor or dentist for instructions before your surgery/procedure. You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely. Limit alcohol while using Metformin ER because it can increase your risk of lactic acidosis and developing low blood sugar. High fever, "water pills" (diuretics such as hydrochlorothiazide), too much sweating, diarrhea, or vomiting may cause dehydration and increase your risk of lactic acidosis. Stop taking Metformin ER and tell your doctor right away if you have prolonged diarrhea or vomiting. Be sure to drink enough fluids to prevent dehydration unless your doctor directs you otherwise. It may be harder to control your blood sugar when your body is stressed (such as due to fever, infection, injury, or surgery). Consult your doctor because increased stress may require a change in your treatment plan, medications, or blood sugar testing. Older adults may be a greater risk for side effects such as low blood sugar or lactic acidosis. During pregnancy, Metformin ER should be used only when clearly needed. Discuss the risks and benefits with your doctor. Your doctor may direct you to use insulin instead of Metformin ER during your pregnancy. Follow your doctor's instructions carefully. Metformin can cause changes in the menstrual cycle (promote ovulation) and increase the risk of becoming pregnant. Consult your doctor or pharmacist about the use of reliable birth control while using Metformin ER. Metformin passes into breast milk in small amounts. Consult your doctor before breast-feeding.
Metformin ER Misdose
If you miss a dose of Metformin ER, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.
Metformin ER Interactions
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar, such as dizziness, hunger, or sweating, are unaffected by these drugs. Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Metformin ER Side Effects
What are Metformin ER side effects?
Side effects are physical, mental or emotional symptoms which occur in addition to or outside of the desired effect of a therapeutic treatment such as an over-the-counter or prescribed drug or medication. Side effects from Metformin ER may occur at the beginning or at the end of treatment and may also depend on the length of time an individual remains on the treatment. Side effects, also known as adverse effects, are generally more likely to occur when starting treatment. Individuals may also experience side effects from Metformin ER as a result of an interaction with other medications.
Side Effects of Metformin ER
The side effects of Metformin ER may vary in number and intensity for many different reasons. Factors such as age, weight, gender and ethnicity may influence the side effects of Metformin ER. Also, an individual’s state of general physical health and seriousness of the disease or illness as well as an increase or decrease in dosage may lead to side effects. Further, side effects from Metformin ER may also occur as a result of an interaction with certain herbal supplements, foods or drinks.
Prescription drug side effects can be serious and may cause patients to stop the treatment. However, when side effects from the use of a prescription drug, such as Metformin ER, do occur a patient should consult their physician. A physician may prescribe an additional treatment in order to control the symptoms or an adjustment in the dosage may be made. In addition, changes to diet, exercise or other lifestyle activities may help to lessen the side effects of Metformin ER.
By understanding side effects and the factors which may influence the occurrence of side effects patients are empowered to take an active role in their care.
