Before taking Viagra, it is essential to discuss all possible effects, risks, and interactions with your doctor or pharmacist.
The same guidelines for use and safe practices apply to generic Viagra in the same way they do for the branded medication, and you can be assured that the availability of generic Viagra means it has also been approved by Health Canada. The vast majority (upwards of 80%) of men who order Viagra online or have their prescription filled in their local pharmacy receive the intended benefit of the medication, and this is also true for those choosing a more affordable alternative in generic Viagra. Take VIAGRA exactly as prescribed by your healthcare professional. The correct dose for each patient will depend on their condition and response. It is recommended to take your daily dose of VIAGRA approximately one hour before you and your partner intend to have sex.
Swallow the tablet whole with a glass of water, and before you buy Viagra be aware that taking more than one dose daily is inadvisable as it greatly increases the risk of severely low blood pressure. Similarly, be aware when your order Viagra online that the time it takes to see the effects of VIAGRA varies from person to person. It normally takes between 30 minutes to 1 hour, and this tends to be true for generic Viagra as well. Patients may notice the medication takes longer to work after a heavy meal. VIAGRA takes effect more quickly when taken on an empty stomach. Common side effects – The following are common side effects of Viagra; other side effects may also occur. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.

In a lower-dose formulation (marketed as Revatio), sildenafil is also used to treat Pulmonary Arterial Hypertension (PAH), a serious condition involving high blood pressure in the lung arteries, for which it is taken regularly, multiple times a day. Viagra (sildenafil) is a Phosphodiesterase-5 (PDE5) inhibitor that functions as a crucial aid in the natural erection process, specifically requiring sexual stimulation to be effective. When a man is sexually aroused, his body produces cyclic Guanosine Monophosphate (cGMP). This chemical signals the blood vessels in the penis to relax and widen, resulting in increased blood flow and an erection. Seek immediate medical attention or call emergency services if you experience any of the following: • A sudden decrease or loss of hearing, sometimes with ringing in the ears and dizziness.
Most are minor and temporary, however, but some may be serious and require medical attention. Speak to your doctor or other trusted healthcare professional immediately if you do not feel well on Viagra. Common and less common side effects are: Abnormal vision (blurred vision, seeing shades of colors differently than before, or sensitivity to light) Decreased or double vision, or in extreme cases, blindness Prolonged, painful, or inappropriate erection of penis (priapism) Redness, burning, or swelling of the eye Other medications can alter the effects of Viagra, and the use of certain other drugs while taking it is not recommended. These potential drug interactions will be detailed in the medication guidelines provided with your prescription. Be sure to ready them in full and seek immediate attention of if you do not feel well while taking the medication – even if you are not taking other medications at the same time.
When used appropriately, VIAGRA is a safe and effective means of treating ED in men. Before taking this medication, be sure to consult your doctor or healthcare professional to confirm it’s right for you. IMPORTANT NOTE: The information provided above is for general awareness and educational purposes only. It is not intended to diagnose, treat, or replace professional medical or veterinary advice. Always consult your physician, pharmacist, or veterinarian regarding the safety, suitability, and proper use of any medication for yourself or your pet. • A sudden decrease or loss of vision in one or both eyes. • Chest pain or other symptoms of a heart attack (like pain spreading to the jaw or shoulder) or stroke, especially during sexual activity. • Priapism: An erection that is painful or lasts for more than four hours.
The PDE5 enzyme is typically present to break down cGMP, thereby terminating the erection. By inhibiting the PDE5 enzyme, sildenafil prevents the rapid degradation of cGMP, thereby prolonging the chemical signal for blood vessel relaxation. This action ensures increased and sustained blood flow to the penile tissues, making it easier to both attain and maintain a firm erection during sexual activity. Take Viagra exactly as prescribed by your doctor, following the instructions in the product monograph in Canada. Consult your doctor for personalized guidance and safe use. This can cause permanent damage to the penis if not treated right away.

VIAGRA may be taken with or without food. The recommended dose for most patients is a 50mg dose approximately 1 hour before sexual activity. Some will find they can take it as soon as 30 minutes before sex and have it take effect in time, while others will find they are best taking it up to 4 hours before sex. The dosage could be upped to 100mg or decreased to 25mg depending on how your respond to the medications and based on your doctor’s recommendations. The maximum dose is once a day, and more detailed information regarding dosage will be found in the printed guidelines for taking the medication included with your purchase when you order Viagra online or pick up your prescription in the pharmacy.
VIAGRA may not be right for some men, and most often because certain medical conditions prevent the individual from be able to take this medication. Patients should discuss the following medical conditions with their healthcare professional before taking branded or generic Viagra. Be aware before your buy Viagra that it may be necessary to discuss any of the following medical conditions: If you are taking any nitrate medication Heart attack, stroke or a history of heart conditions Penile abnormalities, including curved penis and or birth defects Conditions causing thickened blood or slower blood flow, including leukemia, multiple myeloma (tumors of the bone marrow, or polycythemia), sickle cell disease, and thrombocythemia (blood problems) Caution – under no circumstances should men increase their dose without consulting with their healthcare professional. While VIAGRA helps most patients with correcting their erectile dysfunction issues, there is the possibility of unwanted side effects when taking it. All medicines have a possibility of side effects and Viagra in Canada is no exception. Viagra should not be used under the following conditions: • A known hypersensitivity or allergic reaction to sildenafil or any of its ingredients. • The risk of severe, life-threatening hypotension (dangerously low blood pressure).
o Nitrates (e.g., nitroglycerin, isosorbide dinitrate, or isosorbide mononitrate) include: Recreational drugs known as "poppers" (alkyl nitrites). Tell your doctor about your medical conditions, past and present, before starting Viagra.
This is crucial because certain conditions can affect whether Viagra is right for you. These conditions may include, but are not limited to: • Anatomical deformity of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease), as this increases the risk of a prolonged erection (priapism).
