01The basics
What Zionova Cialis is
Cialis is the brand name for tadalafil, a PDE5 inhibitor used to treat erectile dysfunction (ED). It’s nicknamed “the weekend pill” because a single dose can work for up to 36 hours, far longer than sildenafil (Viagra). Each Zionova tablet contains 50 mg of tadalafil, with 50 tablets per bottle.
That 50 mg strength is two and a half times the highest dose approved in Canada (20 mg). This page explains what that means, who shouldn’t take tadalafil at all, and the one interaction that can be life-threatening: 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
An erection depends on blood flow. When you’re aroused, nerves release nitric oxide, which raises a messenger called cGMP. cGMP relaxes the smooth muscle in the penis so blood can flow in. The enzyme PDE5 breaks cGMP down; tadalafil blocks PDE5, so blood flow is easier to start and keep.
- It needs arousal. Tadalafil doesn’t cause an erection on its own, and it doesn’t raise your sex drive.
- It lasts a long time. Its half-life is about 17.5 hours, which is why one dose can work for up to 36 hours, and why side effects can linger just as long.
- Food doesn’t slow it down. Unlike sildenafil, tadalafil works about as well after a meal as on an empty stomach.
04Half-life
Half-life, in plain numbers
A half-life of about 17.5 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
- 17.5 h
- About 97% gone
- 3.6 days
- Levels level out with regular use after
- 2.9 days–3.6 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. For ED taken as needed, the usual starting dose of tadalafil is 10 mg, at least 30 minutes before sex, adjusted to 5 or 20 mg depending on how well it works. The maximum is 20 mg once a day. A low daily dose of 2.5–5 mg is another option. Lower doses are used for people with kidney or liver problems and for those taking drugs that raise tadalafil levels.
One Zionova tablet is 50 mg, two and a half times that maximum. Doses above 20 mg add little benefit but more side effects. Ask a pharmacist whether these tablets can be split accurately.
Talk to a doctor before use, especially if anything in the lists above applies to you.

07Risks
Side effects and risks
Most side effects are mild, but they become more likely as the dose goes up.
Common side effects
Headache, flushing, indigestion, a stuffy nose, and back or muscle aches that can start 12–24 hours after a dose. They usually fade within a day or two.
Never mix with nitrates
Tadalafil with any nitrate, including nitroglycerin sprays, tablets or patches for chest pain and “poppers” (amyl nitrite), can drop blood pressure to dangerous levels. Because tadalafil lasts so long, wait at least 48 hours after a dose before any nitrate.
Low blood pressure
Tadalafil lowers blood pressure slightly. With alcohol, alpha-blockers (such as tamsulosin or doxazosin) or other blood pressure medication, it can cause dizziness or fainting. Stand up slowly.
Erection lasting over 4 hours
This is called priapism. It’s rare, but it’s a medical emergency that can permanently damage the penis. Go to the nearest emergency department; don’t wait it out.
Vision or hearing changes
Stop taking it and get medical help right away for sudden vision loss in one or both eyes, or sudden hearing loss or ringing in the ears.
Don’t use it if you
Take nitrates or riociguat, have been told your heart isn’t healthy enough for sex, recently had a heart attack or stroke, have very low or uncontrolled high blood pressure, have severe liver or kidney disease, or are under 18.
08Interactions
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 knowLong half-life
Tadalafil lasts much longer than sildenafil; leave at least 48 hours after the last tablet before any nitrate.
09Safety
Before you take it
ED is often an early sign of heart disease, diabetes or low testosterone, so it’s worth a check-up even if a pill solves the problem.
- Heart: chest pain, getting short of breath on stairs, or a known heart condition
- Blood pressure: know your numbers; many pharmacies have a free blood pressure machine
- Medications: nitrates, alpha-blockers, blood pressure drugs, and drugs that raise tadalafil levels, such as ritonavir, ketoconazole or clarithromycin
- Grapefruit: grapefruit and its juice also raise tadalafil levels
- Bloodwork worth asking for: fasting glucose or A1C, cholesterol and testosterone
10Tips
Getting the best results
- Take it at least 30 minutes before sex; many people take it a few hours ahead.
- You still need arousal. Foreplay matters more than timing.
- Keep alcohol light. Heavy drinking makes ED worse and raises the chance of dizziness.
- Never take more than one dose in 24 hours, and don’t combine it with Viagra or another ED medication.
- Store it at room temperature, away from moisture.
If tadalafil doesn’t help after a few tries at a proper dose, more isn’t the answer. See a doctor, since ED can have causes a pill won’t fix.

13Questions
Common questions
How long does Cialis last?
Tadalafil can work for up to 36 hours after a dose. It doesn’t keep you erect that whole time; it makes it easier to get and keep an erection when you’re aroused.
Cialis or Viagra: which is better?
Neither is stronger; they work the same way. Sildenafil (Viagra) lasts about 4–6 hours and works best on an empty stomach. Tadalafil lasts up to 36 hours and isn’t affected by food. The best one is the one that fits your routine with the fewest side effects.
Can I drink alcohol with Cialis?
A drink or two is usually fine. Heavy drinking lowers blood pressure further, makes headaches and dizziness more likely, and makes erections harder to get.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is Cialis legal in Canada?
Tadalafil is a prescription drug in Canada (it’s on Health Canada’s Prescription Drug List). It isn’t a controlled substance.
