Covid-19 Service Update

At Medix Pharmacy, the health and safety of our customers and staff is our highest priority. Due to the worldwide Covid-19 pandemic affecting us all, there have been some changes within our industry in general, and in our company specifically, that we want to make our customers aware of.

Call Center

Our current call center hours of operation are 6AM – 9PM every day, seven days per week. If you are experiencing increased hold times or are calling outside of these hours, please leave us a message or send us an email and we will get back to you as soon as we can. Due to increased demand on telephone networks worldwide, you may experience some intermittent connection problems. If this happens our agents will call you back.


We are currently seeing delays in our regular shipping times. Our normal shipping time averages 1 - 2 weeks. Shipments may now take an additional 2 – 4 weeks or more to arrive, depending on the source country of your order.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

These are industry-wide delays and are mainly occurring due to disruptions in local postal delivery in the countries where our customers live. They are temporary, and we thank the shipping and delivery personnel who are working hard for all of us during this global crisis.

Please Note: As these types of shipping delays are not within our direct control, we are temporarily adjusting our regular Shipping Guarantee from 30 days to 60 days. We will provide updates as the situation changes.

Our Commitment

If you have any questions about any changes in our service please do not hesitate to contact us. Our staff are working tirelessly to ensure the timely fulfillment and delivery of all orders. The health of our customers and staff is our highest priority and we remain committed to providing service at the highest level.

We thank you for your support in these challenging times.
