Doctors prescribe Daonil (Daonil) to treat diabetes type 2 which does not respond to dietary measures and which generally only occurs in adults. The tablets lower the sugar content in your blood if this is too high.

Why have I been prescribed Daonil?

  • Doctors prescribe Daonil (Daonil) to treat diabetes type 2 which does not respond to dietary measures and which generally only occurs in adults. The tablets lower the sugar content in your blood if this is too high.

How does it work?

  • Daonil stimulate the release of insulin from the pancreas which increases glucose uptake and reduces the amount in the blood.

When and how do I take it?

  • Unless your doctor has told you differently, take your tablets with or immediately before breakfast or the first main meal of the day.
Swallow them with a glass of water.
  • A physician should be consulted in the event that a dose has not been taken at the prescribed time, a meal has been skipped or an extra dose has been taken.
  • It is very important not to skip meals after the tablets have been taken.
  • What’s the dose?

    The usual dose to take is 5mg daily, but your doctor may advise you to increase this by weekly adjustments with 2.5mg or 5mg Daonil until your blood sugar is under control.

    Could it interact with other tablets?

    Daonil may react with the following drugs:

    • Insulin and other oral antidiabetics
    • ACE inhibitors
    • anabolic steroids and male sex hormones
    • chloramphenicol
    • coumarin derivatives
    • cyclophosphamide
    • disopyramide
    • fenfluramine
    • fenyramidol
    • fibrates
    • fluoxetine
    • ifosfamide
    • MAO inhibitors
    • miconazole
    • para-aminosalicyclic acid
    • pentoxifylline
    • phenylbutazone
    • azapropazone
    • oxyphenbutazone
    • probenecid
    • quinolones
    • salicylates
    • sulfinpyrazone
    • sulfonamides
    • sympatholytic agents such as beta-blockers and guanethidine
    • clarithromycin
    • tetracyclines
    • tritoqualine
    • trosfosfamide

    Weakening of the blood-glucose-lowering effect and, therefore, raised blood glucose levels may occur when taking other drugs, including:

    • Acetazolamide
    • barbiturates
    • corticosteroids
    • diazoxide
    • diuretics
    • epinephrine and other sympathomimetic agents
    • glucagon
    • laxatives
    • nicotinic acid
    • oestrogens and progestogens
    • phenothiazines
    • phenytoin
    • thyroid hormones
    • rifampicin

    H2-receptor antagonists, clonadine, and resperine may lead to either potentiation or weakening of the blood-glucose-lowering effect.
    Under the influence of drugs such as beta-blockers, clonidine, guanethidine, and resperine, the signs of hypoglycaemia may be reduced or absent.
    Daonil may increase cyclosporine plasma concentration and potentially lead to its increased toxicity.
    Both acute and chronic alcohol intake may potentiate or weaken the blood glucose lowering action of Daonil in an unpredicted fashion.
    Daonil may either potentiate or weaken the effect of coumarin derivatives.
    Bosentan: An increased incidence of elevated liver enzymes was observed in patients receiving Daonil concomitantly with bosentan
    Herbal supplements should be used with caution and only after informing your doctor first.

    • Tell your doctor if these are bad or if they last for a long time. If you feel ill after taking the tablets, or notice anything unusual or unexpected, tell your doctor.
    • It is important that you know what to do and what symptoms to expect when low blood sugar (hypoglycaemia) occurs as this is a common side effect.

    • speech and visual disorders
    • aphasia
    • tremor
    • paresis
    • sensory disturbances
    • dizziness
    • helplessness
    • loss of self-control
    • delirium
    • cerebral convulsions
    • somnolence and loss of consciousness up to and including coma
    • shallow respiration and bradycardia

    In addition, signs of adrenergic counter-regulation may be present such as sweating, clammy skin, anxiety, tachycardia, hypertension, palpitations, angina pectoris and cardiac arrhythmias.

    In rare cases your liver may be affected by this medicine making you feel nauseous or you may notice your skin or eyes appear yellowish. In other rare cases you may feel generally weak or faint, breathless on exertion, with a fast heartbeat. You may look very pale or notice some bruising.

Be sure to tell your doctor about any of these symptoms.

    Can I drink alcohol while taking it?

    • Alcohol should be avoided while taking Daonil as it can affect the blood glucose levels in an unpredictable fashion.
