  • NowPatient is worth your time!

    I do not leave reviews, due to time and a rare condition I have. I initially left a message, my call was returned within 2 hours or less. NowPatient offers 4 discount programs. I worked with Jay, he was genuine and wanted to help me all while giving me amazing customer service. Even though I didn't qualify, he gave me some suggestions and tips while encouraging me to follow up with the manufacturer along with other things I could do. This is the real deal, not a scam, and not a waste of your time. Amazing!! Thank you, Jay!

  • Excellent service

    Cannot speak highly enough of the service and assistance I have received from NowPatient. I was dealing with a very kind and helpful clinician who couldn't do enough to assist. He was knowledgeable about the medication being prescribed and the consultation was thorough. There were some hurdles to overcome to receive the medication overseas and nothing was too much trouble. Highly recommend.

    Very good experience - the clinician asked intelligent questions about my insomnia and taught me a lot at the same time. And the medication was dispatched immediately. I’d definitely use them again.
