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 Dantrium

Dantrium or Dantrolene sodium is a drug used for curing muscle cramps and tightness caused due to nerve disorders such as cerebral palsy, stroke, injury and multiple sclerosis. Dantrium is a muscle relaxant; it eases stiffness and muscle pain and improves your ability to move. Dantrium is used in combination with other medications to treat high fever caused due to surgery or anesthesia. Dantrolene sodium is used for curing uncommon conditions such as neuroleptic malignant syndrome that causes muscle stiffness, palpitations and high fever.

Side Effects for Dantrium

Dantrium users can experience weakness, dizziness, drowsiness, fatigue, nausea and diarrhea during the initial days when the body is trying to adjust to this drug. You can also experience constipation, headache and slurred speech. The problem should dissipate after few days, but contact your doctor if the problem persists. In rare cases, patients using Dantrium may experience severe side effects like sun sensitivity, dark stools and vomiting, violent mood swings, change in vision, problems swallowing, difficulty urinating, severe constipation, palpitations, seizures and rapid heartbeat. Contact your doctor immediately if you notice the above side effects or experience signs of infection, swelling of the feet/ankles, and breathing problems.


Make your doctor aware of all the medications that you are using, and are allergic to, before you start using Dantrolene. Inform the doctor if you are suffering from disorders such as hepatitis, cirrhosis or suffer from breathing/heart problems like chronic obstructive pulmonary disease. Using Dantrium can make you extremely sensitive to the sun. Therefore, use adequate protection when you move outdoors and avoid sunbathing or visiting tanning booths. Dantrium is not recommended for pregnant women and mothers who are breastfeeding. Dantrium usage can make you dizzy and drowsy. Do not undertake any activity that requires high alertness after using this muscle relaxant.

Dantrium Dosage

Dantrium 25mg, Dantrium 50mg and Dantrium 100mg capsules are available in the market. Doctors may initially start with a small dosage and gradually increase the dose until the right strength for you is found. Therefore, you may buy Dantrium 25mg for 7 -14 days then the dose will be increased to Dantrium 50mg for the next 7 days. If you still do not find relief, then doctors may recommend you to buy Dantrium 100mg. Manufacturers suggest that your daily dose for Dantrium should not exceed 400mg. The right dosage depends on the age and weight of the patient, medical history and your response to the tablet. If you are using Dantrium for curing hyperthermia then the treatment will continue for several weeks.


Inform doctors about all the prescription/non-prescription/herbal/ and vitamin supplements that you are using before you buy Dantrium. Medications containing estrogen can interact negatively with Dantrium. As this drug can make you sleepy, the drowsiness can increase if you are already using medications like antihistamines, sedatives, anti-anxiety medication, anti seizure medications, muscle relaxants, psychiatric medication and other muscle relaxants. Tell your doctor if you are using hormonal medications or birth control pills as well as heart or blood pressure medications before they prescribe Dantrium.
