Karbis Side Effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. It is important that the patient is aware of what these side effects may be.
Patients must be advised to stop taking Karbis and to seek medical help immediately if they have any of the following allergic reactions: difficulties in breathing, with or without swelling of the face, lips, tongue and/or throat; swelling of the face, lips, tongue and/or throat, which may cause difficulties in swallowing; severe itching of the skin (with raised lumps).
Karbis may cause a reduction in number of white blood cells. The resistance to infection may be decreased and tiredness, an infection or a fever may be noticed. If this happens, advise the patient to contact a doctor. Blood tests may occasionally be done to check whether Karbis has had any effect on the blood (agranulocytosis).

This may make the patient feel faint or dizzy; Changes in blood test results: an increased amount of potassium in the blood, especially if the patient already has kidney problems or heart failure. If this is severe, the patient may notice tiredness, weakness, irregular heart beat or pins and needles; Effects on how the kidneys work, especially if the patient already has kidney problems or heart failure. In very rare cases, kidney failure may occur.

In children treated for high blood pressure, side effects appear to be similar to those seen in adults, but they happen more often. Sore throat is a very common side effect in children. Runny nose, fever and increased heart rate are common in children.
