About Galvus (Vildagliptin)
Galvus (Vildagliptin) is an antidiabetic drug manufactured by the company “NOVARTIS PHARMA, AG” (Switzerland). The medicine is intended for the treatment of type 2 diabetes mellitus in adults. No data are available on the safety of Galvus in children.
Galvus can be used as monotherapy (in adults inadequately controlled by diet and exercise alone and for whom metformin is inappropriate due to contraindications or intolerance) or in combination with other pharmaceutical products (such as metformin, sulfonylurea or thiazolidinedione). A triple therapy (vildagliptin + sulfonylurea + metformin) is permissible. Galvus is also indicated for use in combination with insulin when diet, exercise and a stable dose of insulin don’t provide a desired therapeutic effect.
Composition And Active Ingredients
Galvus is an antidiabetic drug that contains the active substance vildagliptin. The drug also contains such inactive ingredients as microcrystalline cellulose, lactose anhydrous, sodium carboxymethyl starch and magnesium stearate. Galvus is available in the form of 50 mg tablets.
Do I Need A Prescription
Galvus is subject to medical prescription. Patients be monitored closely during the treatment. When prescribing Galvus, the doctor must provide the patients with the information on the safe and efficient use of this drug.
To ensure the effectiveness and safety of treatment with Galvus, always follow the dosage prescribed by your doctor. The health specialist determines the drug dosage individually for each patient taking into account the severity of diabetes and the presence of risk factors (such as liver or kidney failure, old age or alcohol abuse).
How To Take Vildagliptin
You must take Galvus during meals strictly according to the doctor’s recommendations. The recommended dose for adults is:
- 1 pill in the morning and evening (50+50 mg per day) in monotherapy or in combination with metformin, thiazolidinedione, metformin + sulfonylurea/insulin;
- 1 pill in the morning (50 mg per day) in combination with sulfonylurea (to reduce the risk of hypoglycemia).
Never exceed the maximum recommended dosage, as it can cause a number of side effects and negatively affect your health.
The daily dose of the drug shouldn’t exceed 100 mg (2 pills). In patients with renal diseases, the recommended dose of Galvus is 50 mg once daily. The same doses are prescribed to the patients with type 2 diabetes.

What If I Miss A Dose
If you miss a dose of Galvus, don’t take a double dose to make up for a forgotten pill. Take the missed dose as soon as you remember. However, if it’s almost time for your next dose, skip the dose you missed and take your next dose at the usual time.
Information regarding overdose with vildagliptin is limited. Therefore, we will focus on a study in patients given Galvus for 10 days. According to the results of these studies, 400 mg of Galvus caused muscle pain, mild and transient paraesthesia, fever, edema and a transient increase in lipase levels in some patients. At 600 mg, one patient experienced edema of the feet and hands, as well as increases in:
- creatine phosphokinase;
- aspartate aminotransferase;
- C-reactive protein;
After discontinuation of the drug, all the above-mentioned symptoms disappeared without medical intervention.
In case of an overdose, supportive care is recommended. Vildagliptin can’t be removed by hemodialysis. Therefore, you should carefully monitor the drug dosage. In case of overdose, contact your doctor immediately and follow his/her instructions.
Interaction With Other Products
As any other drug, Galvus (Vildagliptin) may interact with other drugs and substances. More information on this is given below.
It is strongly recommended to reduce alcohol consumption while taking Galvus (Vildagliptin). Excessive drinking can cause extremely low blood sugar levels, which will make you feel worse (and in extreme cases- cause serious health problems). Other side effects are also possible. Therefore, patients with type 2 diabetes who take vildagliptin must not abuse alcohol.
Vildagliptin has a low potential for interactions with co-administered medicinal products. Since vildagliptin is not a cytochrome P (CYP) 450 enzyme substrate and doesn’t inhibit or induce CYP 450 enzymes, it is not likely to interact with active substances that are substrates, inhibitors or inducers of these enzymes.
Results from studies conducted with pioglitazone, metformin and glyburide have shown no clinically relevant pharmacokinetic interactions. Clinical studies performed with healthy volunteers taking Galvus in combination with digoxin and warfarin have shown no clinically relevant pharmacokinetic interactions. Drug-drug interaction studies in healthy volunteers were conducted with amlodipine, ramipril, valsartan and simvastatin.
In these studies, no clinically relevant pharmacokinetic interactions were observed after co-administration with vildagliptin. Combined use of vildagliptin and an ACE inhibitor increases the risk of angioedema. You also need to consider that a number of active substances such as corticosteroids, thyroid drugs, thiazides and sympathomimetics, reduce the glucose-lowering effect of vildagliptin. Therefore, any mixing of pharmaceuticals must be performed under the strict supervision of a certified physician.
What Side Effects Are Reported With Galvus?
Like all medicines, Galvus can cause side effects, although not everybody gets them. Practice shows that some side effects go away over time as the patient’s body gets used to a new drug.
Note: Always carry some form of sugar you can eat during the treatment. If you have symptoms of hypoglycemia (cold sweat, cold pale skin, tremor and anxiety), you need to eat something sweet or drink fruit juice to stabilize your blood sugar.
