Hi Dr.,
I am a big fan of your site. I get to read your new posts everyday by subscribing to your RSS feeds. My question is, given that I take 1 tablet of 1mg Propecia everyday, will it interact with other supplements or even certain food?
For example, here’s a list of supplements that I take daily (i take throughout the day, separate times):
1. vitamin b complex and biotin
2. vitamin c
3. vitamin e
4. multi vitamin
5. omega complex
6. co-q10
7. methatione (gluthatione)
Or how about foods:
1. coffee
2. green tea w/ honey
3. soy milk
4. fiber (like wheat bread, fruits)
Just wondering if trying to be health by consuming these will counteract w/ Propecia or vice-versa? Hope this is a valid inquiry.
I have been getting these sorts of questions quite frequently lately. The supplements and foods you’re consuming shouldn’t have any negative interaction with Propecia. The only interaction I can think of with food is with grapefruit, which causes problems for a variety of medications.
The following 16 drugs are listed as having a moderate interaction with finasteride (Propecia): bosentan, diltiazem, diltiazem/enalapril, efavirenz, efavirenz/emtricitabine/tenofovir, fluconazole, fluvoxamine, itraconazole, nefazodone, nelfinavir, posaconazole, rifapentine, saquinavir, sirolimus, tacrolimus, and voriconazole. And there’s 1 drug that has a mild interaction: terazosin. These are the generic names, and for a more complete list (including brand names) see Drugs.com.
