What precautions should be taken?

INSIG can cause an imbalance of the electrolyte levels in the blood. This is more likely if you are vomiting a lot, are on a drip, have heart failure, poor kidney or liver function, or are on a salt restricted diet. If you suffer from a dry mouth, thirst, weakness, fatigue, lethargy, drowsiness, restlessness, muscle pains or cramps, low blood pressure, low urine output, stomach upsets or irregular heart beat, see your doctor.

Take care if you are also taking medicine containing digoxin.

If you are on long term therapy with INSIG TABLETS, ensure the electrolytes in your blood are monitored regularly by your doctor.

INSIG should not be used in pregnant or breastfeeding women unless the benefits of treatment outweigh the potential risk to the child. Your doctor or pharmacist can advise you if you are concerned.

INSIG should not be used if you are taking lithium as INSIG can increase the side effects caused by Lithium.

Advise your doctor if you have Sytemic Lupus Erthematosus (SLE) or gout.

Advise your doctor if you are taking any other medicines including strong pain killers and medicine to treat high blood pressure.

INSIG may cause dizziness or drowsiness, do not drive or operate machinery until you are aware how this medicine may affect you.
