Covid-19 Service Update 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 Cetrotide Injection

Cetrotide Injection (generic name: Cetrorelix) is given to women who are going through certain fertility treatment procedures like controlled ovarian stimulation. Cetrorelix is a GnRH antagonist, which prevents the eggs from being released prematurely from the ovary so that they get enough time to develop appropriately and get released at the right time to encourage pregnancy. You can buy Cetrotide Injection in 0.25mg and 3mg strengths. Cetrotide Injection should not be used by women who are already pregnant.

Side Effects for Cetrotide Injection

Headache, nausea or pain, bruising, swelling, and itching or redness at the injection site are common side effects of Cetrotide Injection, but if any of these conditions become intolerable, you should inform your doctor immediately. Sometimes, you may also experience severe pain, cramping, or swelling in your abdomen, and in such circumstances, you should seek medical help immediately. A minor percentage of female patients who have received Cetrotide Injection may develop OHSS or Ovarian Hyperstimulation Syndrome. Symptoms of this condition include swelling of the legs or hands, severe pelvic pain, pain or swelling in the abdomen, weight gain, shortness of breath, diarrhea, nausea, vomiting, or infrequent urination. If you experience any of these symptoms, you need to stop using Cetrotide Injection and inform your doctor at once. An allergic reaction to this drug may be identified by rashes, severe dizziness, swelling or itching of the face, throat, tongue or lips, and trouble breathing.


Before you buy Cetrotide Injection, you should inform your doctor if you have an allergy to Cetrorelix or if you have a history of kidney disease or any severe allergic reactions. This injection cannot be given to a woman who is already pregnant, and if you become pregnant during treatment, you should inform your doctor promptly. Breastfeeding mothers should also take this injection only if extremely necessary, because its safety for a newborn baby has not been established. As the injection cannot be given to pregnant women, you may need to undergo a pregnancy test one week before starting treatment.

Cetrotide Injection Dosage

You may be given Cetrotide Injection 0.25mg once a day everyday for several days or be asked to take a single dose of Cetrotide Injection 3mg, which is administered subcutaneously. The injection is given in your lower abdomen around 1 inch away from your belly button. After that, an ultrasound will be taken, and if shows that you are ready for ovulation, an hCG injection will be given to you so that the eggs can be matured and released. After this, you may become pregnant within a few days.


While using Cetrotide Injection, you should stop taking any birth control pills that control your hormones or any other hormonal methods of contraception. As you are taking this medicine to get pregnant, you should not use any kind of contraceptive method, which can prevent you from getting pregnant. Other than this, you should inform your doctor about all the medicinal products you are taking at present, including herbal products, health supplements, mineral and vitamin supplements, and prescription or non-prescription drugs.
