01The basics
What Viagra by Genetix Pharma is
Genetix Pharma’s Viagra contains sildenafil citrate, 30 mg per tablet with 50 tablets per bottle. Sildenafil was the first erectile dysfunction pill, and generic versions have been sold in Canada for over a decade.
At 30 mg, each tablet sits between the 25 mg and 50 mg doses used in practice, a gentler option for men who get side effects at 50 mg. The essential safety point is the same as any ED pill: never combine it with nitrates.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.
03How it works
How it works
Sildenafil blocks PDE5, the enzyme that breaks down cGMP. With more cGMP, blood vessels in the penis relax more easily during arousal.
- Starts in 30–60 minutes, slower after a fatty meal.
- Lasts about 4–6 hours, with a half-life of about 4 hours.
- Needs arousal; it doesn’t raise libido.
04Half-life
Half-life, in plain numbers
A half-life of about 4 hours means half of what is in the body is gone after that time, then half of the rest, and so on. For a tablet this is mostly about how fast the liver clears it; food and the person change it a little.
- One half-life
- 4 h
- About 97% gone
- 20 h
- Levels level out with regular use after
- 16 h–20 h
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. The usual sildenafil dose is 50 mg about an hour before sex, adjusted between 25 mg and 100 mg, no more than once a day. A 25 mg start is used for people over 65, with liver or severe kidney problems, or on drugs that raise sildenafil levels.
One Genetix tablet is 30 mg, near the low end of that range. Talk to a doctor before use.

Add to cart08Risks
Side effects and risks
A lower dose usually means fewer side effects, but the serious interactions don’t change.
Common side effects
Headache, flushing, stuffy nose, indigestion and, occasionally, a blue tint to vision.
Never with nitrates
Nitroglycerin or “poppers” with sildenafil can cause a dangerous blood pressure drop. Wait at least 24 hours after a dose.
Dizziness
Alpha-blockers, blood pressure medicines and alcohol add to sildenafil’s effect on blood pressure.
Priapism
An erection lasting over 4 hours needs emergency care.
Vision or hearing loss
Sudden loss of vision or hearing means stop and get help right away.
Don’t use it if you
Take nitrates or riociguat, have unstable heart disease, recently had a heart attack or stroke, have very low blood pressure, retinitis pigmentosa, or are under 18.
09Interactions
Interactions
Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.
- SeriousNitrates and poppers
Nitroglycerin sprays and patches, isosorbide tablets and amyl or alkyl nitrite “poppers” combined with a PDE5 inhibitor can drop blood pressure to a dangerous level. Never mix them.
- SeriousRiociguat (Adempas)
The same dangerous fall in blood pressure. Not to be combined.
- CautionAlpha-blockers and blood-pressure medicines
Tamsulosin, doxazosin, terazosin and similar drugs add to the drop in pressure, causing dizziness or fainting when you stand up.
- CautionKetoconazole, ritonavir, clarithromycin, grapefruit
These block the enzyme (CYP3A4) that clears PDE5 inhibitors, so blood levels can climb several-fold.
- Good to knowAlcohol
Lowers blood pressure further and makes erections harder to get, which defeats the purpose.
- Good to knowTiming
Leave at least 24 hours after sildenafil before any nitrate.
10Safety
Before you take it
- Medications: nitrates, alpha-blockers, and drugs that raise sildenafil levels (ritonavir, ketoconazole, clarithromycin)
- Other ED drugs: don’t combine with Cialis, Supermans or similar
- A check-up: ED can be an early sign of heart disease or diabetes
11Tips
Getting the best results
- Take it about an hour before sex, ideally on an empty stomach.
- Give it a few tries before judging it.
- Limit alcohol.
- One dose per 24 hours.
