Dosage/Direction for Use
In principle, the dosage of Amaryl is governed by the desired blood sugar level. The dosage of glimepiride must be the lowest which is sufficient to achieve the desired metabolic control. Treatment with Amaryl must be initiated and monitored by a doctor.
Amaryl must be taken at the times and in the doses prescribed. Mistakes, e.g. forgetting to take a dose, must never be corrected by subsequently taking a larger dose. Measure for dealing with such mistakes (in particular forgetting a dose or skipping a meal) or situations where a dose cannot be taken at the prescribed time must be discussed and agreed between doctor and patient before-hand. A doctor must be notified immediately if the dose taken is too high, or an extra dose has been taken.
The initial and the maintenance doses are set based on the result of regular checks of glucose in blood and urine. Monitoring of glucose levels in blood and urine also serves to detect either primary or secondary failure of therapy. Initial dose and dose titration: The usual initial dose is 1 mg Amaryl once daily. If necessary, the daily dose can be increased. Any increase should be based on regular blood sugar monitoring, and should be gradual, i.e. at intervals of one to two weeks, and carried out stepwise, as follows: 1 mg-2 mg-3 mg-4 mg, and-in exceptional cases-8 mg.
Dose range in patients with well controlled diabetes: The usual dose range in patients with well controlled diabetes is 1 to 4 mg Amaryl daily. Only some patients benefit from daily doses of more than 6 mg.
Distribution of doses: Timing and distribution of doses are decided by the doctor, taking into consideration of the patient's current life-style. Normally, a single daily dose of Amaryl is sufficient. This dose should be taken immediately before a substantial breakfast of if none is taken immediately before the first main meal. It is very important not to skip meals after taking Amaryl.
Secondary dosage adjustment: As the control of diabetes improves, sensitivity to insulin increases; therefore, glimepiride requirements may fall as treatment proceeds. To avoid an excessive reduction in blood sugar (hypoglycaemia) a timely dose reduction or of Amaryl therapy must be considered.
A dose adjustment must also be considered whenever the patient's weight of life-style changes, or other factors causing an increased susceptibility to hypoglycaemia or to an excessive increase in blood sugar levels (hyperglycaemia) arise (see Precautions).
Duration of treatment: Treatment with Amaryl is normally a long-term therapy. Changeover from other oral antidiabetics to Amaryl: There is no exact dosage relationship between Amaryl and other oral blood-sugar-lowering agent. When substituting Amaryl for other such agents, the initial daily dose is 1 mg; this applies even in changeovers from the maximum dose of another oral blood sugar lowering agent. Any Amaryl dose increase should be in accordance with guidelines given previously in Initial dose and dose titration.
Consideration must be given to the potency and duration of action of the previous blood-sugar-lowering agent. It may be necessary to interrupt treatment to avoid additive effects which would increase the risk of hypoglycaemia. Use in combination with metformin: Whenever blood sugar levels cannot be controlled adequately with the maximum daily dose of either Amaryl or a metformin-containing antidiabetic alone, both medicines may be used concomitantly. In such cases, the dose of the established medicine remains unchanged. Treatment with the additional medicine is started at a low dose, which-depending on the desired blood sugar level-may then be increased gradually up to the maximum daily dose. Combined treatment should be initiated under close medical supervision.
Use in combination with insulin: Whenever blood sugar levels cannot be controlled adequately with the maximum daily dose of Amaryl, insulin may be given concomitantly. In this case, the current dose of Amaryl remains unchanged. Insulin treatment is started at a low dose, which is subsequently increased stepwise according to the desired blood sugar level. Combined treatment should be initiated under close medical supervision.
Long term efficacy should be monitored by measurement of HbA1c levels, for example every 3 to 6 months. Short term administration of Amaryl may be sufficient during periods of transient loss of control in patients usually controlled well on diet and exercise. There is limited information available on the use of Amaryl in renal insufficiency. Patients with impaired renal function may be more sensitive to the glucose-lowering effect of Amaryl.
Administration: Amaryl tablets must be swallowed without chewing and with sufficient amounts of liquid (approx. ½ glass).
