Your kidneys remove Neoformin from your body. If your kidneys don’t work well, you’ll have higher levels of Neoformin in your system. This raises your risk of lactic acidosis.
If you have mild or moderate kidney problems, your doctor may start you at a lower dosage of Neoformin.
If you have severe kidney problems or are 80 years old or older, Neoformin may not be right for you. Your doctor will likely test your kidney function before you start taking Neoformin and then again each year.
Surgical or radiologic procedures
If you plan to have surgery or a radiology procedure that uses iodine contrast, you should stop taking Neoformin 48 hours before the procedure.
These procedures can slow the removal of Neoformin from your body, raising your risk of lactic acidosis. You should resume taking Neoformin after the procedure only when your kidney function tests are normal.
1) Insulin Resistance
Insulin resistance is one of the major factors contributing to the development of type 2 diabetes but is also observed in PCOS and as a side effect of HIV therapy .
Neoformin improved insulin sensitivity in cell-based and animal studies and decreased the effects of insulin resistance in diabetic patients .
Moreover, a clinical trial of 25 HIV patients with lipodystrophy, a condition in which the body is unable to generate fat tissue, showed that Neoformin reduced the risk of abnormally high insulin levels in the blood .
A small trial on 10 people showed that Neoformin improved insulin sensitivity produced by exercise .
In insulin-resistant rats, the combination of Neoformin and electroacupuncture increased insulin sensitivity through the activation of an enzyme that mediates insulin’s activity ( GLUT4 ) .

Nausea, vomiting, stomach upset, diarrhea, weakness, or a metallic taste in the mouth may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. If stomach symptoms return later (after taking the same dose for several days or weeks), tell your doctor right away. Stomach symptoms that occur after the first days of your treatment may be signs of lactic acidosis.
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.
Neoformin does not usually 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 of your other diabetes medication(s) needs to be lowered.
Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, 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 about the reaction right away. Low blood sugar is more likely if you drink large amounts of alcohol, do unusually heavy exercise, or do not consume enough calories from food. 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).
Stop taking this medication and tell your doctor right away if this very serious side effect occurs: lactic acidosis (see Warning section).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any of the following symptoms of a serious allergic reaction: 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.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.

Lactic acidosis is a rare but dangerous side effect of Neoformin, occurring in an estimated 1 in 30,000 people who take the drug.
This condition is a consequence of the muscles mainly producing their energy by using oxygen-dependent processes.
During strenuous or prolonged activity, the body can need more oxygen than is available, so the cells switch to anaerobic, or oxygen-lacking, processes.
Anaerobic glucose breakdown produces lactic acid, which breaks down further into lactate. The liver then processes lactate into glucose.
Lactate levels can rise during extended exercise or strenuous activities, as the body needs oxygen to help clear it. When lactate does not clear from the bloodstream quickly enough, it can build up, increasing blood and muscle acidity.
When lactate levels are too high, lactic acidosis occurs. Neoformin slows the rate of lactate uptake by the liver, as does alcohol.
The risk of developing lactic acidosis while on Neoformin alone is quite rare. However, when a person takes Neoformin alongside alcohol, the risks increase significantly.
The U.S. Food and Drug Administration (FDA) issued a black box warning on Neoformin packaging about lactic acidosis. They have listed alcohol use disorder as a risk factor for developing this dangerous complication while on Neoformin.
Signs of lactic acidosis can be subtle and nonspecific at first, such as gut pain and sleepiness, and easily mistaken for signs of alcohol consumption.
Severe lactic acidosis has intense symptoms that are quick to appear, however.
Lactic acidosis can be life-threatening. If symptoms occur, people should seek medical attention immediately.
Warning signs of lactic acidosis include:
- cramping or pain, particularly around the gut
- fast or shallow breathing
- fluttering heartbeat
- general discomfort
- muscles seizures
- intense weakness
- decreased appetite
- low blood pressure
- high pulse rate
What Is Neoformin and How Does It Work?
Neoformin is a drug approved by the U.S. Food and Drug Administration as a prescription medication to treat diabetes. This medication is used to decrease hepatic (liver) glucose production, to decrease GI glucose absorption and to increase target cell insulin sensitivity. This medication is a treatment indicated as an adjunct to diet, exercise, and lifestyle changes such as weight loss to improve glycemic (blood sugar) control in adults with type 2 diabetes. Many patients with type 2 diabetes will eventually need to take insulin by injection. Neoformin does not cause weight gain.
Immediate action required: Call 999 or go to A&E if:
- you get a skin rash that may include itchy, red, swollen, blistered or peeling skin
- you're wheezing
- you get tightness in the chest or throat
- you have trouble breathing or talking
- your mouth, face, lips, tongue or throat start swelling
You could be having a serious allergic reaction and may need immediate treatment in hospital.
These are not all the side effects of Neoformin.
For a full list, see the leaflet inside your medicines packet.
You can report any suspected side effect to the UK safety scheme.
10 to 80 years unless normal renal function establishedInitial and maintenance dosing of Neoformin should be conservative in patients with advanced age due to the potential for decreased renal function in this population
Controlled clinical studies of Neoformin did not include sufficient numbers of elderly patients to determine whether they respond differently from younger patients
What other drugs will affect Neoformin?
Many drugs can interact with Neoformin, making it less effective or increasing your risk of lactic acidosis. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all your current medicines and any medicine you start or stop using.
8. Cautions with other medicines
There are some medicines that interfere with the way Neoformin works.
If you're taking any of the following medicines, your blood sugar levels may need to be checked more often and your dose adjusted:
- steroid tablets, such as prednisolone
- tablets that make you pee more (diuretics), such as furosemide
- medicines to treat heart problems and high blood pressure
- male and female hormones, such as testosterone, oestrogen and progesterone
- other diabetes medicines
Some women might need a small adjustment in their Neoformin dose after starting contraceptive pills. That's because contraceptive pills change how your body handles sugar.
