Actigall (Generic Ursodiol): Complete Medication Guide
Key Takeaways
Ursodiol helps dissolve gallstones and protects the liver by increasing bile flow.
Common side effects include diarrhea, nausea, and stomach discomfort, which are usually mild.
Take ursodiol exactly as prescribed, typically two to three times daily with food.
This medication works best for small, uncalcified gallstones and may take months to show results.
Always discuss your liver function and medical history with your doctor before starting treatment.
Actigall (Generic Ursodiol) Overview
Ursodiol is a naturally occurring bile acid used to treat gallstones and protect liver health. It works by reducing the amount of cholesterol produced by the liver and increasing the flow of bile. This helps dissolve small gallstones over time and prevents new ones from forming. Ursodiol is also prescribed to prevent gallstone formation in people losing weight rapidly and to treat certain liver conditions.
The generic version of Actigall contains the same active ingredient as the brand-name drug and works identically in your body. Generic vs Brand Name Drugs explains how generic medications deliver the same therapeutic benefits at lower costs. Ursodiol is available as capsules and is typically taken by mouth with food to improve absorption and reduce stomach upset.
This medication is particularly useful for people who want to avoid gallbladder surgery or who are not candidates for surgical removal. Treatment usually lasts six months to two years, depending on the size and number of gallstones and how well your body responds to therapy.
Side Effects
Ursodiol is generally well tolerated, though some people experience mild gastrointestinal effects. Most side effects decrease over time as your body adjusts to the medication.
Common Side Effects
Diarrhea – The most frequent side effect; occurs because ursodiol increases bile flow and can soften stools.
Nausea – Mild queasiness, usually worse on an empty stomach; taking the drug with food helps reduce this.
Stomach pain or cramping – Mild abdominal discomfort may occur, especially when first starting treatment.
Indigestion – Heartburn or acid reflux can develop; antacids may help if bothersome.
Headache – Mild head pain occurs in some patients but typically resolves without intervention.
Hair loss – Temporary thinning or shedding may occur but usually reverses after treatment ends.
Serious Side Effects
Severe allergic reaction – Rash, swelling of the face or throat, or difficulty breathing require immediate medical attention.
Liver damage – Yellowing of skin or eyes, dark urine, or severe fatigue may indicate liver problems.
Pancreatitis – Severe upper abdominal pain radiating to the back suggests inflammation of the pancreas.
Gallbladder complications – Persistent right upper quadrant pain or fever may signal infection or obstruction.
Severe diarrhea – Watery stools lasting more than a few days can lead to dehydration and electrolyte imbalances.
When to Seek Medical Attention
Contact your doctor if you experience persistent diarrhea lasting more than a week, yellowing of the skin or eyes, dark urine, or severe abdominal pain. These symptoms may indicate your liver or gallbladder needs evaluation. Seek emergency care if you develop signs of a serious allergic reaction, such as difficulty breathing, swelling of the throat, or severe rash.
If you develop new symptoms or feel that your current side effects are worsening, don't wait—call your healthcare provider. They can adjust your dose, recommend supportive treatments, or switch you to an alternative if needed.

Important: Do not skip doses or stop taking ursodiol without speaking to your doctor, even if your gallstones dissolve. Stopping early increases the risk of gallstone recurrence. If you miss a dose, take it as soon as you remember, but skip it if it's almost time for your next dose. Never double up on doses to make up for a missed one. Your doctor will monitor your progress with ultrasounds and blood tests to track how well the medication is working.
Drug Interactions
Ursodiol can interact with certain medications and supplements, reducing its effectiveness or increasing the risk of side effects. Inform your doctor of all medications you take before starting treatment.
Cholesterol-Lowering Drugs (Statins)
Medications like simvastatin and lovastatin may reduce the effectiveness of ursodiol by decreasing bile acid production. Your doctor may adjust doses or monitor you more frequently if you take both medications together.
Antacids Containing Aluminum or Magnesium
These antacids can bind ursodiol in your stomach, preventing proper absorption. Take ursodiol at least two hours apart from aluminum or magnesium-containing antacids for best results.
Bile Acid Sequestrants (Cholestyramine, Colesevelam)
These drugs bind bile acids in the intestines and may reduce ursodiol absorption. Space doses at least two hours apart and inform your doctor if you take both medications.
Estrogen and Hormonal Contraceptives
Estrogen increases cholesterol secretion in bile, which can counteract ursodiol's gallstone-dissolving effects. Discuss contraceptive options with your doctor if managing gallstones is important to your treatment plan.
Cyclosporine and Immunosuppressants
Ursodiol may reduce cyclosporine levels in your blood, potentially decreasing its effectiveness. Your doctor may need to monitor drug levels or adjust doses if you take both medications.
NSAIDs (Ibuprofen, Naproxen)
Long-term NSAID use increases gallstone risk and may work against ursodiol therapy. Use the lowest effective dose for the shortest time possible, and discuss alternatives with your doctor.

Ursodiol works slowly. Most people need treatment for 6 to 24 months before gallstones fully dissolve. Smaller stones dissolve faster than larger ones.
