Taking Actos (pioglitazone) can help lower blood sugar, but it also brings side effects some people notice right away and others that show up over time. This page explains the most common issues, the serious risks to watch for, and simple steps you can take to stay safe while on this drug.
Many people on Actos report mild, manageable effects. Weight gain is one of the most common — the drug can increase fat storage and make you retain water. That often shows up as a few pounds gained over weeks to months. Swelling in the ankles or legs (edema) is another frequent complaint. If you feel puffier than usual or your shoes get tight, mention it to your doctor.
Actos can also make low blood sugar (hypoglycemia) more likely when combined with insulin or sulfonylureas. Symptoms include sweating, shakiness, dizziness, or sudden hunger. Learning how to spot and treat low blood sugar is useful if you use other diabetes medicines alongside Actos.
Some risks are less common but more serious. Fluid retention from Actos can worsen or trigger heart failure. If you notice shortness of breath, sudden weight gain (several pounds in a few days), or swollen feet, get medical help right away. People with a history of heart failure usually shouldn’t take pioglitazone.
There’s evidence linking pioglitazone to a small increased risk of bladder cancer, especially after long-term use. If you see blood in your urine, have pain when peeing, or notice unexplained pelvic pain, tell your clinician immediately.
Bone fractures appear more often in some people taking Actos, particularly older women. If you develop new bone pain or break a bone more easily than before, mention it to your provider. Liver injury is rare but possible — watch for yellowing skin/eyes, dark urine, severe nausea, or persistent stomach pain. Doctors often check liver tests at the start and if symptoms appear.
Before you start Actos, tell your doctor about heart disease, bladder problems, a history of cancer, liver disease, or if you’re pregnant or planning pregnancy. Ask how this medicine interacts with other drugs you take.
Practical tips: weigh yourself weekly, check ankles for swelling, report breathlessness or sudden weight gain, and avoid hiding symptoms. If you’re worried about long-term risks, ask about alternatives like metformin, GLP-1 receptor agonists, or SGLT2 inhibitors — your doctor can explain which fits your situation better.
Actos helps many people, but awareness matters. Watch for changes, keep routine checkups, and call your healthcare team if anything feels off.
