Lightheadedness, dizziness, shakiness, or hunger may happen if your blood sugar is too low. Call your doctor if low blood sugar levels are a problem for you.
- diabetic eye disease with swelling in the back of the eye (macular edema). Tell your doctor right away if you have any changes in your vision. Your doctor should check your eyes regularly.

Call your doctor right away if you have any of the following:
- swelling or fluid retention, especially in the ankles or legs

- unusual tiredness

Talk to your doctor before taking Actos if you have either of these conditions.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
