Tandemact is used for the treatment of type 2 (non-insulin dependent) diabetes mellitus. This is the diabetes that usually develops in adulthood.
Tandemact helps control the level of sugar in your blood when you have type 2 diabetes by increasing the amount of insulin available and helping your body make better use of it.

Important information about some of the ingredients of Tandemact:
This medicinal product contains lactose monohydrate. If you have been told by your doctor that you have intolerance to some sugars, contact your doctor before taking Tandemact.
Always take Tandemact exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The usual dose is one tablet taken once daily shortly before or with the first main meal. Tablets should be swallowed whole with some liquid. If necessary your doctor may tell you to take a different dose.
If you have the impression that the effect of Tandemact is too weak, talk to your doctor.
If you are following a special diet for diabetes, you should continue with this while you are taking Tandemact.
Your weight should be checked at regular intervals; if your weight increases, inform your doctor.
In clinical trials in which pioglitazone was compared to other oral anti diabetic medicines or placebo (dummy pill), a higher number of bone fractures was seen in women (but not in men) taking pioglitazone. Your doctor will take this into account when treating your diabetes.
Some patients with long-standing type 2 diabetes mellitus and heart disease or previous stroke who were treated with pioglitazone and insulin experienced the development of heart failure. Inform your doctor as soon as possible if you experience signs of heart failure such as unusual shortness of breath or rapid increase in weight or localised swelling (oedema).
Your doctor will ask you to have blood tests periodically during treatment with Tandemact.
If you take more Tandemact than you should:
If you accidentally take too many tablets, or if someone else or a child takes your medicine, talk to a doctor or pharmacist immediately.
If you forget to take Tandemact:
Try to take Tandemact daily as prescribed. However if you miss a dose, just carry on with the next dose as normal. Do not take an extra tablet to make up for the one you missed.
If you stop taking Tandemact:
Do not stop taking Tandemact without first discussing it with your doctor or pharmacist.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
