Covid-19 Service Update

At North Drugstore, 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.

Full information about Marquis Paste

General Information on Marquis Paste

Marquis Paste is used for treating equine protozoal myeloencephalitis, or EPM, caused due to Sarcocystis neurona. The medicine is meant to be given to horses.

Active ingredient in the medicine is Ponazuril, and it belongs to the class of anticoccidial or antiprotozoal compounds with activities against different genera of phylum Apicomplexa.

It is given to the horse in the form of an oral paste. It is available in ready-to-use syringes so that its administration is made easier. The medicine works by reaching the parasite’s central nervous system, killing them at any stage of their lives.

Side effects of Marquis Paste

The veterinarian will not recommend you to buy Marquis Paste if your pet has allergy to Ponazuril, or if it is meant for food. Before starting treatment with Marquis Paste, make sure that the horse is not suffering from any other disease such as in-coordination, which has almost same signs as EPM.

Also inform the veterinarian if your horse is pregnant, lactating or breeding, as special adjustments may be needed during or before the treatment.

Because the medicine is not meant for human consumption, you should not give it to your horse if you are going to use it for food. Avoid getting the medicine ingested into your system, as severe reactions may take place. Do not smoke, eat or drink anything while handling the medicine, as it may accidentally get ingested by you.

Some of the side effects associated with Marquis Paste include hives, rashes, diarrhea, blisters, seizures or signs of mild colic. Notify the veterinarian immediately if your horse encounters any of these symptoms, as some adjustments may need to be made.

Some horses may also develop an allergic reaction to the medicine. Signs of an allergy include hives, facial swelling, shock, sudden onset of diarrhea, scratching, cold limbs, coma, seizures or pale gums. Contact the veterinarian at once if your pet encounters any of these symptoms.

Dosage of Marquis Paste

The veterinarian will advise you to give Marquis Paste 5mg per kg of the horse’s body weight once in a day, for 28 days.

Before administering the paste into the horse’s mouth, you need to make sure that there is not remaining feed in the pet’s mouth. Because each paste tube contains multiple doses, you have to measure the dose correctly and ensure that you are giving the right dose to your pet.

Once you have deposited the paste in your horse’s mouth, raise its head immediately for a few seconds so that the paste can be swallowed completely.

Drug Interactions of Marquis Paste

The veterinarian will not recommend you to buy Marquis Paste if your horse is allergic to the medicine, or if you are already giving it other medicines to treat the same condition.

You must also tell the veterinarian about all the prescription and non-prescription veterinary drugs you are giving to your pet at present, including herbal preparations and nutritional or health supplements. Depending on these, the veterinarian will be able to decide whether this medicine is the right product for your pet or not.
