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 Dyrenium

Dyrenium is indicated for patients who are suffering from edema caused due to nephritic syndrome, cirrhosis of the liver, or congestive heart failure. Triamterene belongs to the group of diuretics, which prevent the body from absorbing too much salt. The medicine works by increasing urine production, thus allowing for the extra loss of sodium and preventing the loss of potassium from kidneys. You can buy Dyrenium in the form of oral capsules with 50mg strength. This drug can also be used to reduce blood pressure when taken together with some other drugs.

Side Effects for Dyrenium

Dry mouth, dizziness, blurred vision, constipation, insomnia, and weight gain are some common side effects of the drug, but you need to watch out if you experience difficulty urinating, have a decreased cough reflex, butterfly shaped rashes on the cheeks and nose, swelling on the feet or ankles, joint or muscle pain, vision changes, muscle weakness, feel unusually hot or cold, skin discoloration, or sun sensitivity. Sometimes, Dyrenium may also cause nervous system or muscle related problems like restlessness or a constant need to keep moving, stiff muscles, a shuffling walk, tremors, feelings of anxiety, agitation, or jitteriness, trouble swallowing or drooling, severe cramping or muscle spasms, or mask-like facial expressions. As this drug may sometimes lead to tardive dyskinesia, you should look out for symptoms like uncontrolled lip smacking, tongue thrusting, mouth puckering, or chewing. Triamterene sometimes increases prolactin levels in your body, which can lead to unwanted breast milk, stopped or missed periods, difficulty getting pregnant, enlarged breasts, decreased libido, and an inability to produce sperm (males). If you get a prolonged and painful erection for more than 4 hours, you need to seek medical help immediately.


Before you buy Dyrenium, you should inform your doctor if you have a kidney or liver disease, hyperkalemia, diabetes, heart disease, gout, kidney stones, or if you are using potassium supplements or any other diuretics. As the drug may increase your sensitivity to the sun, you should avoid being exposed to the sun, sunlamps, or tanning booths, and if you need to go out, you should wear protective clothes and apply sunscreen. Dyrenium decreases sweat production, so you should avoid getting overheated due to strenuous activities and hot weather.

Dyrenium Dosage

You may be asked to take an initial dose of 2 Dyrenium 50mg capsules per day, which can be increased as per your medical condition and response to treatment. A daily dose should not exceed Dyrenium 300mg a day. Take the capsules with a full glass of water without chewing, crushing or breaking them.


Some products that may interact with Dyrenium include antispasmodic drugs, anticholinergic drugs, water pills, and drugs that increase dopamine in the body. As this drug may make you dizzy, you should avoid using other products that cause the same effect, including antihistamines, anti-anxiety medications, sleeping pills, muscle relaxants, narcotic pain relievers, and tranquilizers. Some drugs that may increase risks of seizure when taken with Dyrenium include tricyclic antidepressants, tramadol, theophylline, isoniazid and bupropion.
