What is G-Tab M?
G-Tab M is used to treat high blood sugar levels caused by type 2 diabetes. It may be used alone, or in combination with insulin or another oral medicine such as G-Tab M. In type 2 diabetes, insulin produced by the pancreas is not able to get sugar into the cells of the body where it can work properly. Using G-Tab M will help lower blood sugar when it is too high and help restore the way you use food to make energy.. Some people can control type 2 diabetes with diet alone or diet and exercise. Following a specially planned diet and exercising will always be important when you have diabetes, even when you are taking medicines. To work properly, the amount of G-Tab M you take must be balanced against the amount and type of food you eat and the amount of exercise you do. If you change your diet, your exercise, or both, you will want to test your blood sugar to find out if it is too low. Your doctor will teach you what to do if this happens.
G-Tab M is available only with your doctor's prescription.
G-Tab M indications
NIKP-G-Tab M tablet 3 mg is used as monotherapy as adjunct to diet and exercise for the management of type II diabetes mellitus (non-insulin-dependent diabetes mellitus) in patients whose blood glucose levels cannot be controlled adequately by diet and exercise alone.
NIKP-G-Tab M tablet 3 mg also may be used in combination with one or more other oral anti-diabetic agents containing G-Tab M or insulin as adjunct to diet and exercise for the management of type II diabetes mellitus (non-insulin diabetes mellitus) patients whose blood glucose levels cannot be controlled adequately by diet, exercise and oral antidiabetic agent monotherapy.
How should I use G-Tab M?
Use G-Tab M as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take G-Tab M by mouth with breakfast or the first main meal of the day unless your doctor tells you otherwise.
- G-Tab M works best if it is taken at the same time each day.
- Continue to take G-Tab M even if you feel well. Do not miss any doses.
- If you miss a dose of G-Tab M, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use G-Tab M.
Uses of G-Tab M in details
G-Tab M is used to lower the blood sugar levels in type 2 diabetes mellitus when diet, physical exercise and weight reduction alone are not adequate.
G-Tab M description
Each tablet contains the following colourants: G-Tab M 1 mg: Ferric oxide (red); G-Tab M 2 mg: Ferric oxide (yellow) and lake of indigo carmine.
It also contains the following excipients: Lactose, microcrystalline cellulose, sodium starch glycollate, povidone, crospovidone, purified talc, magnesium stearate and anhydrous colloidal silica.
G-Tab M dosage
Always take NIKP-G-Tab M exactly as the physician has prescribed.
The dose depends on the patient's needs, condition and results of blood and urine sugar tests and is determined by the physician. The patient should not take more tablets than what the physician has prescribed.
Usual Starting Dose: 1 mg once daily. If necessary, the physician may increase the dose after each 1-2 weeks of treatment. Max Dose: 6 mg/day.
A combination therapy of G-Tab M + G-Tab M or of G-Tab M + insulin may be initiated. In such case, the physician will determine the proper doses of G-Tab M, G-Tab M or insulin individually.
Inform the physician if the patient's weight or lifestyle changes or in a stressful situation, this may require change in NIKP-G-Tab M doses.
If the patient feels the effect of the medicine is too weak or too strong, do not change the dose, consult the physician.
Missed Dose: If the patient forgot to take a dose, do not take a double dose to make up for forgotten doses.
If treatment is interrupted or stopped, the patient should be aware that the desired blood sugar-lowering effect will not be achieved or that the disease will deteriorate again. Keep taking NIKP-G-Tab M until the physician tells the patient to stop.
Administration: Take NIKP-G-Tab M by mouth, just before or with the 1st main meal of the day (usually breakfast). If the patient does not take breakfast, take NIKP-G-Tab M as prescribed by the physician. It is important not to leave out any meal when the patient is on NIKP-G-Tab M.
Swallow the tablet whole with at least ½ glass of water. Do not crush or chew the tablets.
G-Tab M interactions

What other drugs will affect G-Tab M?
Drug-Drug Interactions: Increased blood glucose lowering effect of G-Tab M can occur when NIKP-G-Tab M tablet 3 mg is taken with:
Oral antidiabetics, injectible antidiabetics (eg, GLP-1 agonists, insulin), ACE inhibitors, allpurinol, androgens (male sex hormones: eg, anabolic steroids), fenfluramine, antibiotics (eg, chloramphenicol and tetracyclines), anticoagulant (eg, coumarin derivatives), anti-depressants (eg, fluoxetine, fluvoxamine), guanethidine, cyclophosphamide, ifosfamide, trofosfamide, azole antifungals (eg, fluconazole, miconazole), β-blockers (eg, propranolol), disopyramide, clarithromycin, CYP450 2C9 inhibitors, fenyramidol, fibrates, histamine H2-antagonists, MAOIs, NSAIDs (eg, azapropazone, oxyphenbutazone, para-aminosalicylic acid, phenylbutazone, salicylates), pentoxifylline, quinolones, sulfonamides, tritoqualine, uricosuric (eg, probenecid, sulfinpyrazone) and herbs with hypoglycemic properties.
Decreased blood glucose lowering effect of G-Tab M can occur when NIKP-G-Tab M tablet 3 mg is taken with: Rifampicin, phenytoin, nicotinic acid, diazoxide, barbiturate, corticosteroids, CYP2C9 inducers, diuretics (eg, acetazolamide and thiazide diuretic), epinephrine (eg, adrenaline), glucagon, oestrogens, progestogens, thyroid, isoniazid, laxatives (after protracted use), phenothiazines and sympathomimetics.
Either increased or decreased blood glucose lowering effect of G-Tab M can occur when NIKP-G-Tab M tablet 3 mg is taken with: Clonidine, reserpine and H2-receptor antagonists.
The effect of coumarin derivatives may be potentiated or weakened when coumarin derivatives are taken with NIKP-G-Tab M tablet 3 mg.
Drug-Food Interactions: Both acute and chronic alcohol intake may increase or decrease the blood glucose lowering action of G-Tab M unpredictably.
Others: The signs of adrenergic counter-regulation to hypoglycemia may be reduced or absent due to the influences of sympatholytics eg, β-blockers, clonidine, guanethidine and reserpine. β-blockers decrease glucose tolerance which may lead to deterioration of metabolic control in patients with diabetes mellitus Additionally, β-blockers may increase the tendency to hypoglycemia due to impaired counter-regulation.

What are the possible side effects of G-Tab M?
The following serious adverse reactions are discussed in more detail below and elsewhere in the labeling:
- Hypoglycemia
- Hemolytic anemia
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Approximately 2,800 patients with type 2 diabetes have been treated with G-Tab M in the controlled clinical trials. In these trials, approximately 1,700 patients were treated with G-Tab M for at least 1 year.
Table 1 summarizes adverse events, other than hypoglycemia, that were reported in 11 pooled placebocontrolled trials, whether or not considered to be possibly or probably related to study medication. Treatment duration ranged from 13 weeks to 12 months. Terms that are reported represent those that occurred at an incidence of ≥5% among G-Tab M-treated patients and more commonly than in patients who received placebo.

| G-Tab M N=745 % | Placebo N=294 % | |
| Headache | 8.2 | 7.8 |
| Accidental InjuryInsufficient information to determine whether any of the accidental injury events were associated with hypoglycemia |
Hypoglycemia
In a randomized, double-blind, placebo-controlled monotherapy trial of 14 weeks duration, patients already on sulfonylurea therapy underwent a 3-week washout period then were randomized to G-Tab M 1 mg, 4 mg, 8 mg or placebo. Patients randomized to G-Tab M 4 mg or 8 mg underwent forced-titration from an initial dose of 1 mg to these final doses, as tolerated. The overall incidence of possible hypoglycemia (defined by the presence of at least one symptom that the investigator believed might be related to hypoglycemia; a concurrent glucose measurement was not required) was 4% for G-Tab M 1 mg, 17% for G-Tab M 4 mg, 16% for G-Tab M 8 mg and 0% for placebo. All of these events were self-treated.
In a randomized, double-blind, placebo-controlled monotherapy trial of 22 weeks duration, patients received a starting dose of either 1 mg G-Tab M or placebo daily. The dose of G-Tab M was titrated to a target fasting plasma glucose of 90–150 mg/dL. Final daily doses of G-Tab M were 1, 2, 3, 4, 6 or 8 mg. The overall incidence of possible hypoglycemia (as defined above for the 14-week trial) for G-Tab M vs. placebo was 19.7% vs. 3.2%. All of these events were selftreated.
Weight Gain
G-Tab M, like all sulfonylureas, can cause weight gain.
Allergic Reactions
In clinical trials, allergic reactions, such as pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions, occurred in less than 1% of G-Tab M-treated patients. These may resolve despite continued treatment with G-Tab M. There are postmarketing reports of more serious allergic reactions (e.g., dyspnea, hypotension, shock).
Laboratory Tests
Elevated Serum Alanine Aminotransferase (ALT)
In 11 pooled placebo-controlled trials of G-Tab M, 1.9% of G-Tab M-treated patients and 0.8% of placebo-treated patients developed serum ALT greater than 2 times the upper limit of the reference range.
Postmarketing Experience
The following adverse reactions have been identified during post-approval use of G-Tab M. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
- Serious hypersensitivity reactions, including anaphylaxis, angioedema, and Stevens-Johnson Syndrome
- Hemolytic anemia in patients with and without G6PD deficiency
- Impairment of liver function (e.g. with cholestasis and jaundice), as well as hepatitis, which may progress to liver failure.
- Porphyria cutanea tarda, photosensitivity reactions and allergic vasculitis
- Leukopenia, agranulocytosis, aplastic anemia, and pancytopenia
- Thrombocytopenia (including severe cases with platelet count less than 10,000/μL) and thrombocytopenic purpura
- Hepatic porphyria reactions and disulfiram-like reactions
- Hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH), most often in patients who are on other medications or who have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone
- Dysgeusia
- Alopecia

What is the most important information I should know about G-Tab M?
G-Tab M is not suitable for the treatment of insulin-dependent (type I) diabetes mellitus (eg, for the treatment of diabetics with a history of ketoacidosis), of diabetic ketoacidosis, or of diabetic precoma or coma. G-Tab M must not be used in patients hypersensitive to G-Tab M, other sulfonylureas, other sulfonamides, or any of the excipients (risk of hypersensitivity reactions).
No experience has been gained concerning the use of G-Tab M in patients with severe impairment of liver function and in dialysis patients. In patients with severe impairment of renal or hepatic function, a changeover to insulin is indicated, not least to achieve optimal metabolic control.
Use in pregnancy & lactation: To avoid risk of harm to the child, G-Tab M must not be taken during pregnancy; a changeover to insulin is necessary. Patients planning a pregnancy must inform their physician and should changeover to insulin. Ingestion of G-Tab M with the breastmilk may harm the child. Therefore, G-Tab M must not be taken by breastfeeding women. Either a changeover to insulin or a complete discontinuation of breastfeeding is necessary.
