I just downloaded this app, of course I put it to the test, just from what I know, and I can honestly say, it's very informative, gives you all the information you'll need. Easy to use, I haven't been through everything it offers, but so far, so good.
Btw, I don't usually even take the time to write these things, I thought this one was worth doing though, and the fact it's for me.

This helps you to understand what the side effects are of your medication(s), especially if you're trying to conceive and want to know what medications you can take and not take as well as in general! Thank 🙏🏼 for this app!

Not complete enough

I purchased the ad free version of this app so that I could access important interaction information regarding an antidepressant medication that I take. This app had zero information available beyond a simple description of the drug. This app may be adequate for people taking the most common drugs only, but I would question its comprehensiveness regarding interactions for anything because some drugs are left out. I simply trashed it after 5 minutes of use.

Developer Response ,

Thank you for your feedback. We're sorry to hear that the app was not helpful for you. As we are always looking to add new sources, it is possible that more medications, and more information about each medication, will be added in the future.
