| PRECAUTIONS |
Physician's dietary recommendations should be followed while using gliclazide. They will enhance gliclazide's efficacy.
There are certain drugs, which may increase or decrease gliclazide hypoglycemic effect. The physician must be informed about the drugs the patient are taking so that he can adjust the dosage, if necessary.
Certain drugs have the potential to increase gliclazide's hypoglycemic effect, e.g.
- Non-steroidal anti-inflammatory drugs (in particular, aspirin)
- Antibacterial sulfonamides, coumarin anti- coagulants, MAOIs, beta-blockers, perhexiline maleate, chloramphenicol, clofibrate, and miconazole tablets.
- Administration of alcohol may also increase the hypoglycemic effect of gliclazide.
Some drugs, on the contrary may, reduce gliclazide's effectiveness, e.g.
- Barbiturates, corticosteroids, thiazide diuretics and oral contraceptives.
High doses or a low-carbohydrate or unbalanced carbohydrate diet may lead to an excessive decrease in blood sugar (hypoglycemia). Hypoglycemia is manifested by a feeling of malaise, sweating, pallor, hunger pangs, increased heart rate.
In this case:
* Some sugar should be taken and physician should be informed.
* Caution is needed in the elderly or those with hepatic and renal insufficiency because of the hazard of hypoglycemia.
