Interactions between your drugs

Major

vitamin A tretinoin

Applies to: vitamin a and tretinoin

Using vitamin A together with tretinoin is generally not recommended. Combining these medications may increase the risk of hypervitaminosis A, a condition that stems from excessive vitamin A-related effects. Potentially serious problems that could occur include vision impairment, increased pressure in the brain, high cholesterol/triglycerides, and inflammation of the liver, pancreas, or the rest of the digestive tract. Check your food and medicine labels to make sure you do not consume additional vitamin A in excess of the recommended daily allowance. Talk to your doctor or pharmacist if you are uncertain whether you are getting too much vitamin A. Early signs and symptoms of hypervitaminosis A include inflammation or bleeding of the gums or lips; dry, scaly, itchy, or red skin; hair loss; headache; dizziness; and nausea. You should seek immediate medical attention if you experience potential signs that could indicate increased pressure in the brain (headache, nausea, vomiting, visual disturbances) or liver damage (fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, yellowing of the skin or eyes). It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
