More about Guanfacine

This medication is used alone or with other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Guanfacine acts in the brain. It decreases certain nerve signals from the brain to the blood vessels and the heart. This causes the blood vessels to relax so that blood can flow more easily and also slows the heart rate. These effects help to lower blood pressure.
Take this medication by mouth with or without food, usually once daily at bedtime or as directed by your doctor. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. It may take several weeks before you get the full benefit of this medication. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Also, you may experience symptoms such as headache, nervousness, agitation, tremor, fast heartbeat, and high blood pressure. To prevent these symptoms while you are stopping treatment with this drug, your doctor may reduce your dose gradually. Ask your doctor or pharmacist for more details. Report any new or worsening symptoms right away. Tell your doctor if your condition does not improve or if it worsens (for example, your routine blood pressure readings remain high or increase).
Dry mouth, drowsiness, dizziness, constipation, tiredness, and weakness may occur. Decreased sexual ability has been reported rarely. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute. To lower your risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if you have any serious side effects, including: severe dizziness, fast/slow heartbeat, fainting, mental/mood changes (such as depression, hallucinations, confusion, thoughts of suicide). A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist. In the US - Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch. In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets. Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Tell your doctor or pharmacist if you are taking other products that cause drowsiness including alcohol, marijuana (cannabis), antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), and narcotic pain relievers (such as codeine, hydrocodone). Check the labels on all your medicines (such as cough-and-cold products, diet aids, nonsteroidal anti-inflammatory drugs-NSAIDs such as ibuprofen for pain/fever reduction) because they may contain ingredients that cause drowsiness or could increase your blood pressure or heart rate. Ask your pharmacist about using those products safely.
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: severe drowsiness, severe dizziness, severe tiredness, very slow heartbeat.

Frequently Asked Questions

We've compiled a list of commonly asked questions for your convenience. If you are unable to find the answer to your question, please contact us for further assistance. It's just one more way UPRx prioritizes your self-care.


If you are one of half of the US population who benefits from taking prescription drugs, then UPRx is for you. We offer cash medication so you can…

• Bypass high insurance copays.
• Order with complete discretion.
• Purchase without insurance policy limitations and restrictions.
• Have access to lower priced medications
• Order your medication without insurance
• Avoid the hassle of going to the pharmacy to fill your prescriptions.

If any of the above sound as awesome to you as they do to us, we can safely say that UPRx is the alternative for you.
In order to fulfill your order we will need a corresponding prescription. However, if you don’t already have one we can help you with that! We have partnered with a third-party Telehealth company, providing online consultations with US licensed doctors, for a $5 fee.
We make it easy! All we require is contact information for your pharmacy or doctor’s office, and we will take care of transferring your prescription over for you. If you do not have an existing prescription, you can talk to one of our online physicians now and they can submit a prescription directly into our system for you.
UPRx.com offers both generic and brand-name prescription medications. The generic versions are generally significantly cheaper than the brand name version of a drug. However, please consult with your doctor to find out which variation of any specific drug is best for you.
With the exception of our products’ pricing and our third- party Telehealth service, the use of our website and services are completely cost-free.
After your order is placed, UPRx will retrieve your valid prescription from your doctor or pharmacy. Once the prescription is confirmed as authorized and corresponding to your order, our participating pharmacy begins to process your order. Depending on the specific drug and location, we can ship out some products as soon as same day, and we commit to shipping out all products within 48 hours of verifying your prescription.
Our site does not support insurance at this time, as we are focusing our efforts on getting you the best cash price. You may not know this, but there are some instances where it’s significantly cheaper to pay cash for a medication rather than to order it through your insurer’s pharmacy benefits program. Here at UPRx, we cut out the middleman and do the negotiating for you- providing you with the same drugs, for less pay.
Nothing should stand in the way of you getting the drugs you need to feel and perform your best. UPRx orders arrive in discreet packaging, because your health is personal, and should remain that way.
UPRx operates under strict HIPAA compliance laws and regulations to ensure that your privacy is paramount.
UPRx is fully registered and operates in multiple locations across the United States of America. Our partner pharmacy, Apogee BioPharm is licensed and operated in all 50 states and territories. At UPRx we are committed to only purchasing locally sourced items and products. When UPRx obtains your medical information while acting on your behalf, we will maintain the privacy and security of that information in accordance with the standards of the HIPAA security regulations.
