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 Invanz Injection

Invanz injection is an antibiotic used to treat bacterial infections. The generic name of this antibiotic is Ertapenem, which belongs to the antibiotics class called Carbapenems. The antibiotic cures infections by killing the bacteria that cause them. Invanz injection is recommended to treat a variety of severe bacterial infections of the lungs, skin, stomach, pelvis, and urinary tract.

It is also used to treat diabetic foot infections in patients having chronic bone infection and to prevent infections in particular types of surgery. You may have to buy Invanz injection if you are unable to tolerate other antibiotics or if other antibiotics are not able to cure the bacterial infection.

Invanz Side Effects

Some patients may experience side effects or allergic reactions after taking the Invanz injection. You should immediately talk to your doctor if you notice or experience any side effects such as diarrhoea, nausea, vaginitis (in females), and headaches.

Some patients may also experience an allergic reaction after taking Invanz injection. You should immediately notify your doctor about any allergic reaction that you may notice after taking Invanz injection. Some of the allergic reactions of the drug that may occur are: difficulty in breathing, tightness in the chest, swelling of the mouth, tongue, face, or lips, and bloody stools.

Some patients may also experience chest pain, rapid heartbeat, chills, fever, sore throat, redness or swelling at the injection site, severe cramps, or stomach pain. Women may experience unusual vaginal discharge or odor after taking the Invanz injection. These side effects and allergic reactions are serious and need medical attention. You should not take any medications to cure the side effects without consulting your doctor.


You should inform your doctor if you have any allergies or are allergic to Cephalosporins, penicillin, or any amide-type local anaesthetics such as Lidocaine. It is necessary that you inform the doctor before the medication is injected into your muscle as this product also contains inactive ingredients that may cause allergic reactions or other medical problems.

Discuss your medical history with your doctor before taking Invanz. Your doctor will need to know if you have suffered from a head injury, brain disorder, tumor, any stomach or intestinal diseases, or any kidney disease before prescribing Invanz injection. Pregnant women should inform their doctor before they buy Invanz injection to cure bacterial infections.


For patients who are 13 years or older, the dosage is Invanz injection 1 gram once a day. For younger patients, in the age group 3 months to 12 years, dosage is Invanz injection 15mg, twice a day. Dosage should never increase 1g per day. Intravenous infusion of the injection can be taken for up to 14 days and or it be taken as an intramuscular injection for 7 days. Intravenously the injection needs to be infused over a period of half an hour (30 minutes)


The drug may not interact well with other medications you take and can cause serious side effects. Therefore, it is necessary that you tell your doctor about every medication you take. You should not arbitrarily make a decision to start, stop or change the dosage of other medications after taking an Invanz injection in fear of suffering from the side effects. The antibiotic may interact with other drugs such as Probenecid, live bacterial vaccines, and Valproic acid/Divalproate. Invanz may also reduce the effectiveness of hormonal birth control pills.
