itraconazole user desperately need help

I have been using itraconazole for a month and my doctor told me that my treatment will last for 6 months or more.

I was told to go to take a blood test for itraconazole level but there is no Lab offering this test at all.

I also need to know what foods and medications to avoid.

1. Medications (Stomach medication should be avoided and yes! I tried to take stomach medication one hour prior taking itraconazole. I can confirm that they are in conflict) But what other medication that I should avoid?

2. I was told that I must not have dairy products 2 hours before and after taking itraconazole. Is it true? What other foods that I should avoid?

3. Alcohol must be avoided.

4. I am also concern about the side effects.

Please help. Thank you.

We are not medical professionals, so are unable to help you. May I recommend you re-read the leaflet that will have co e with your medication, as it may answer some of your questions, and also speak to your Pharmacist. They have a wealth of knowledge on medication, and side effects. Hope you get your answers.



I thought someone may be able to share their experience.

I am seeing the doctor this Wednesday and I shall ask about the blood test.

Thank you.

Hello .stomach meds should be avoided if possible.been on itraconazole for over 12months and nobody has ever mentioned dairy produce. As for alchohol? Dont know dont drink myself. And sideeffects can vary. But the do subside after i while i found.


There are labs in the UK that can test your blood levels of itraconazole. The one I am familiar with is here at the National Aspergillosis Centre and there are full contact details at - you can guide your doctor to it! It is an NHS service.

Itraconazole should not be taken at the same time as an antacid and I see you know that - I can't think of any other common drug that will cause a problem though we know that grapefruits should also be avoided.

I don't know what the advise about not taking milk is about (all warnings are noted here unless they are referring to one research paper that featured a child being treated with ringworm. It is suggested that whole milk might enhance uptake or efficiency but the evidence is slim.

It is always best to avoid alcohol when taking medication as it plays havoc with doses!

A list of the possible side effects are given in the leaflet above. These can be kept to a minimum by carefully controlling blood levels. All too often people put up with severe side effects when in fact there is a problem with too high dose - always refer side effects to your doctors for advice.

I hope that helps
