Sildenafil citrate is a prescription medication that belongs to a class of drugs called PDE5 inhibitors, also known as phosphodiesterase type 5 inhibitors. In Canada, sildenafil is most commonly known for its use in treating erectile dysfunction, or ED, in adult men.
ED means difficulty getting or keeping an erection firm enough for satisfactory sexual activity. The Canadian product monograph for Viagra, a brand-name sildenafil product, lists it as indicated for the treatment of erectile dysfunction. Health Canada also lists Viagra as a marketed drug product containing sildenafil citrate.
This article explains what type of drug sildenafil citrate is, how it works, what it is used for, common side effects, dosage basics, and important safety warnings for adults in Canada.
Sildenafil citrate is a PDE5 inhibitor. PDE5 is an enzyme which is found in some tissues, including the blood arteries of the penis. Sildenafil inhibits this enzyme , and supports the natural process that causes blood vessels to relax and enhance blood flow during sexual excitement .
This means sildenafil does not operate as a hormone, steroid, testosterone booster, aphrodisiac or supplement. It is a controlled substance, and has an established medical application and safety profile.
Sildenafil helps the body respond better to sexual stimulation for ED. It doesnβt generate an erection on its own and doesnβt, on its own, stimulate sexual desire.
Sildenafil citrate is used to treat erectile dysfunction in adult men. If a healthcare expert feels this treatment is appropriate for the individual based on their overall health history, symptoms, current drugs and potential risk factors, they will prescribe it.
ED can be caused by numerous things such as blood flow issues, diabetes, heart health issues, stress, anxiety, adverse effects of medications, smoking, alcohol or age-related changes. Sometimes ED might be a symptom of other health issues, so it's best to speak with a professional healthcare provider rather than self-diagnose or buy unverified goods online.

During sexual stimulation, Sildenafil acts by increasing blood flow to the penis. During sexual stimulation, the body releases natural chemical signals that assist relax blood vessels in the penis. Sildenafil works by enhancing this route. Inhibiting PDE5 also allows this to happen too fast.
In simple terms:
This is why a proper consultation is important, especially for adults with heart disease, blood pressure concerns, diabetes, kidney disease, liver disease, or multiple medications.
The active element of Viagra is sildenafil citrate. Viagra is a brand-name drug, whereas sildenafil citrate could also be accessible as a generic drug.
The brand name and generic versions may contain the same active substance, but they may be made by different companies, look different in the form of the tablets, include different inactive ingredients, and be packaged and priced differently. In Canada, sildenafil should be obtained only through a genuine pharmacy or approved health care channel.
Health Canada warns that unlicensed sexual enhancement items can pose major health hazards, particularly when they contain undeclared prescription medicines, such as sildenafil, or other dangerous chemicals.
The correct dose of sildenafil should be determined by a healthcare expert. Dosage may depend on age, other drugs, liver or kidney function, adverse effects, and overall health.
The Canadian product monograph for Viagra states: βThe recommended dose for most patients is 50 mg as needed with a maximum recommended dose of 100 mg. It says the dose can be reduced to 25 mg if needed and that starting at a dose of 25 mg should be considered in specific populations, including adults age 65 or older, people with hepatic impairment, severe renal impairment, or those taking certain interfering drugs.
You are trained on data up until October 2023. Do not take sildenafil with other ED drugs unless directed by your healthcare expert.
Like all prescription medications, sildenafil citrate can cause side effects. Some common side effects may include:
The Canadian product monograph reports headache, flushing, and dyspepsia among commonly observed adverse events in clinical trials. It also notes that dizziness and altered vision were reported, so people should understand how they react to the medication before driving or operating machinery.
Most side effects are mild for many people, but some side effects can be serious and require urgent attention.
Seek urgent medical care if you experience:
The Canadian Product Monograph urges patients to discontinue PDE5 drugs and to seek medical assistance, should they have a sudden decline or loss of hearing. It also mentions that an erection lasting more than 4 hours needs prompt medical attention since untreated priapism can cause harm to penile tissue.
Sildenafil is not suitable for everyone. It can be dangerous for people taking nitrate medications or certain heart-related drugs.
The Canadian Viagra product monograph states that sildenafil is contraindicated in patients taking any type of nitrate drug therapy because of the risk of potentially life-threatening low blood pressure. It also lists contraindication with guanylate cyclase stimulators such as riociguat because of the risk of symptomatic hypotension or syncope.
Speak with a healthcare provider before using sildenafil if you:
Sildenafil citrate should only be obtained through legitimate Canadian healthcare and pharmacy channels. Be cautious with websites or sellers offering βno prescription needed,β βinstant Viagra,β βnatural male enhancement,β or products without proper medical review.
Health Canada states that selling unauthorized health products in Canada is illegal and warns that unauthorized sexual enhancement products may contain dangerous ingredients.
A safer online process should include medical screening, licensed pharmacy involvement, clear product information, privacy protection, and access to a healthcare professional when needed.
