Talk to the doctor if the patient is suffering or have ever suffered from any of the following conditions or illnesses: Kidney disease or kidney transplant; renal artery stenosis (narrowing of the blood vessels to one or both kidneys); liver disease; heart trouble; raised aldosterone levels (water and salt retention in the body along with imbalance of various blood minerals); low blood pressure (hypotension), likely to occur if the patient is dehydrated (excessive loss of body water) or have salt deficiency due to diuretic therapy ('water tablet'), low-salt diet, diarrhoea, or vomiting; elevated potassium levels in the blood; diabetes.
Tell the doctor if the patient thinks she is (or might become) pregnant. Telmisartan Actavis is not recommended in early pregnancy, and must not be taken if the patient is more than 3 months pregnant, as it may cause serious harm to the baby if used at that stage (see Use in Pregnancy & Lactation).
In case of surgery or anaesthesia, tell the doctor that the patient is taking Telmisartan Actavis.
Telmisartan Actavis may be less effective in lowering the blood pressure in black patients.
Dual blockade of the renin-angiotensin-aldosterone system (RAAS): There is evidence that the concomitant use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren increases the risk of hypotension, hyperkalaemia and decreased renal function (including acute renal failure). Dual blockade of RAAS through the combined use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren is therefore not recommended.
If dual blockade therapy is considered absolutely necessary, this should only occur under specialist supervision and subject to frequent close monitoring of renal function, electrolytes and blood pressure.
ACE-inhibitors and angiotensin II receptor blockers should not be used concomitantly in patients with diabetic nephropathy.
Children and adolescents: The use of Telmisartan Actavis in children and adolescents up to the age of 18 years is not recommended.
Telmisartan Actavis contains mannitol: If the patient is intolerant to some sugars, consult the doctor before taking Telmisartan Actavis.
Driving and using machines: Some people feel dizzy or tired when taking Telmisartan Actavis. If the patient feels dizzy or tired, do not drive or operate machinery.
