Covid-19 Service Update

At Pharmacy Rx World, 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 6:00 am – 9:00 pm, seven days a 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. Shipments from the United Kingdom and Canada are generally quicker than from other countries.

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: We are now resuming our normal 30-Day Shipping Guarantee. 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.

General Information On Denavir

Denavir is a topical cream used to treat cold sores. This drug fall under the category of drugs known as antivirals. Penciclovir (generic name of this medicine) works by stalling the growth of the virus that causes cold sores and herpes simplex type 1.

Patients should apply this cream as soon as they notice signs of a cold sore. Denavir provides relief from the symptoms of cold sores such as burning, tingling, itching, and pain. It does not cure cold sores or prevent future occurrences.

Side Effects for Denavir

Patients who buy Denavir have reported experiencing a few mild side effects such as rashes, a feeling of numbness or tingling sensation in the area where the cream is applied, change in taste, and mild headache. These symptoms mostly subside within a few days. However, you should contact your doctor if any of the above-mentioned symptoms worsen over time. Denavir is not known to cause any serious side effects.

You are unlikely to experience an allergic reaction while using Penciclovir. With that said, you must seek emergency medical help if you notice any symptoms of an allergic reaction (shortness of breath, wheezing, breathing trouble, hives, or swelling of your lips, face, tongue, or other body parts.

It is possible that this medication may cause side effects that are not listed above. The patient information leaflet that you receive when you buy Denavir should list all the side effects. This is why it is recommended that you go through the patient information leaflet before starting treatment.


Before you use this medicine, let your doctor know if you are allergic to Penciclovir or Famciclovir. Also, talk to your doctor in detail about any other allergies that you have. In addition, inform him or her about your medical history and other medicines that you are using.

Denavir should be applied only on the face and lips. Do not apply this drug near your eyes or inside your nose or mouth, as doing so may cause irritation. If Denavir cream has got into your eye, then you must quickly clean your eye with water.

If you are pregnant, use Denavir only after consulting your doctor. It is unclear if this drug is excreted into breast milk. Lactating women should therefore consult their doctor before using this medicine to treat cold sores.

Denavir Dosage

Depending on your condition and response to treatment, your doctor will determine the right Denavir dosage. This medicine is most effective when it is used at regular intervals. Your doctor will advise you about how often and for how long you must apply this medicine. Do not increase or decrease the Denavir dose on your own. You must store the medicine at room temperature, away from moisture and heat.


You must consult your doctor before using any other topical medicines, especially if you are applying it on the same spot where you are applying Denavir. Also, before you start the treatment, tell your doctor about all the medications that you are taking.
