Interactions and overdose


The effects of Avodart can change if you take it at the same time as other medications and herbal products. This can increase your risk or serious side effects or may even cause Avodart to not work correctly. Because negative drug interaction is always a possibility, you should always tell your doctor or pharmacist about all products (prescription, non-prescription, and herbal) before you start taking Avodart. Your doctor or pharmacist will then be able to help you prevent or manage interactions by changing how you use your medications or by closely monitoring your progress.

While using Avodart, do not suddenly stop even if you start to see results. Do not change your dosage of this or any other medication either without first consulting your doctor or pharmacist. Keep a list of all the products you use and share that list with your doctor so that he or she can help monitor your use and progress. That way you can reduce your risk of serious medical problems.


If you suspect an overdose of Avodart, immediately contact your nearest poison control centre or emergency room.

  • Medications prescribed to you are for your individual health problems and should not be shared with others.
  • Laboratory and medical tests like prostate exams and prostate-specific antigen-PSA should be performed to monitor your progress and check for side effects. Consult your doctor or healthcare specialist for more details.
  • If you miss taking a dose of Avodart, take it as soon as you remember. If it is nearer to your next dose, skip the missed dose and resume your usual dosing schedule. Do not double your doses of Avodart to try to catch up, this could result in overdose.
  • Always store Avodart at room temperature, and away from light and moisture. Capsules may soften and leak if they are stored at high temperatures. If Avodart capsules start to crack and leak, do not use them.
  • If your skin comes into contact with leaking capsules, wash the area immediately with soap and water.
  • Keep medications away from children and pets by storing them in a specific medicine cabinet rather than just on the bathroom shelf.
  • Do not flush damaged or expired medications down the toilet or pour them down the drain, unless you have been directly advised by your doctor or pharmacist to do so. Properly discard all medications when they are no longer needed and consult your pharmacist or local waste disposal company if in doubt.
