Cialis® Tablets for Erectile Dysfunction and BPH

Cialis® is a prescription tablet used to treat erectile dysfunction and the urinary symptoms of benign prostatic hyperplasia. This page helps you learn how it works, how to use it, and how to access Canadian pricing. Ordered from Canada and shipped to the US, your package arrives as US delivery from Canada. Many patients also look for ways to manage the overall cost without insurance.

What Cialis® Is and How It Works

Cialis® contains tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. In erectile tissue, it blocks the PDE5 enzyme, helping nitric oxide increase cyclic GMP levels. This relaxes smooth muscle and improves blood flow to support an erection with sexual stimulation. In the prostate and bladder, it relaxes smooth muscle, which can ease urinary symptoms of BPH.

CanadianInsulin is a prescription referral service. We verify your prescription with your clinic, and licensed Canadian pharmacies dispense your order.

The medicine is for adult men diagnosed with erectile dysfunction or BPH. It does not treat low desire and is not approved for women or children. Cialis works with or without food and can be used either as needed for sexual activity or once daily depending on the indication and plan set by your prescriber.

Who Cialis® Is For

Cialis is indicated for adult men with erectile dysfunction. It is also indicated for men with urinary symptoms due to benign prostatic hyperplasia. For men who have both ED and BPH, a daily Cialis regimen may be used for both conditions.

Men taking nitrate medicines for chest pain must not use tadalafil because of the risk of a sudden, dangerous blood pressure drop. Avoid use with guanylate cyclase stimulators such as riociguat. People with recent stroke, recent heart attack, unstable angina, uncontrolled blood pressure, severe liver disease, or severe kidney disease may not be candidates. Discuss cardiac safety and sexual activity with a clinician if there is a history of heart disease. For more background on urinary symptoms, review our guide to Benign Prostatic Hyperplasia.

Dosage and Usage

Follow the directions on your prescription label. Typical regimens include:

• As-needed ED use: 10 mg taken prior to anticipated sexual activity. The dose may be lowered to 5 mg or raised to 20 mg based on effectiveness and tolerability. Do not take more than once per day.
• Once-daily ED use: 2.5 mg to 5 mg taken at the same time each day, without regard to timing of sexual activity.
• BPH (with or without ED): 5 mg taken once daily, at about the same time each day.

Take the tablet with a glass of water. Sexual stimulation is required for ED benefit. Do not split or crush tablets unless your prescriber instructs otherwise. Avoid taking more than directed.

Strengths and Forms

Cialis is supplied as film-coated oral tablets. Commonly available strengths include:

• 2.5 mg tablet
• 5 mg tablet
• 10 mg tablet
• 20 mg tablet

Availability of specific strengths may vary.

Missed Dose and Timing

For once-daily dosing, if a dose is missed, take it when remembered if it is not close to the next dose. If it is near the time for the next dose, skip the missed dose. Do not take two doses at once.

For as-needed dosing, take only before sexual activity as directed. Do not take more than one dose in a 24-hour period.

Storage and Travel Basics

Store Cialis tablets at room temperature. Keep the bottle tightly closed, protected from moisture, and away from heat. Keep out of reach of children and pets. When traveling, carry your medicine in your hand luggage, with the original label visible for security screening. Do not store in a bathroom or other high-humidity location.

For online orders, your checkout is encrypted.

Benefits

When used as directed, Cialis helps improve erectile function. As-needed dosing can work in as little as 30 minutes for many patients and may last up to 36 hours. This longer window can reduce time pressure around intimacy. Daily dosing is an option for men who prefer readiness any day of the week.

For men with BPH, tadalafil can reduce urinary frequency, urgency, and weak stream. The once-daily dose is simple to follow. Taking the medicine with or without food adds convenience.

Side Effects and Safety

• Headache
• Indigestion or stomach upset
• Back pain
• Muscle aches
• Flushing
• Nasal congestion
• Dizziness

Most effects are mild and tend to lessen over time. Rare but serious reactions include an erection lasting more than 4 hours (priapism), sudden vision loss (possible NAION), sudden hearing decrease or loss, severe allergic reaction, or fainting. Chest pain during sexual activity requires immediate medical attention. Combining tadalafil with nitrates or certain blood pressure drugs can lead to unsafe hypotension. Limit excessive alcohol, which may increase dizziness or blood pressure drops.

Drug Interactions and Cautions

Do not use Cialis with any form of nitrate (nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, or recreational nitrates). Avoid use with guanylate cyclase stimulators such as riociguat. Use caution with alpha blockers for prostate or blood pressure; your prescriber may separate timing or adjust therapy. Tadalafil can enhance the blood pressure–lowering effect of antihypertensives.

Strong CYP3A4 inhibitors (for example, ketoconazole, itraconazole, ritonavir, and clarithromycin) can increase tadalafil levels and may require dose adjustments or avoidance. Strong CYP3A4 inducers (for example, rifampin, carbamazepine, phenytoin) can reduce effectiveness. Grapefruit or grapefruit juice may increase tadalafil exposure. Discuss kidney or liver problems with your clinician, as dosing limits can apply.

What to Expect Over Time

With as-needed use, some men notice improved erections after the first dose, especially when taken at least 30 minutes before sexual activity. Benefits may persist up to 36 hours. With once-daily dosing, steady levels build over several days. For ED, daily regimens may take a few days of consistent use for best effect. For BPH, urinary symptoms often improve over days to weeks.

Response varies by dose, other medicines, meal timing, and health factors. If the starting dose is not effective or causes side effects, clinicians often adjust within the approved range.

Compare With Alternatives

Other PDE5 inhibitors may suit different preferences. Sildenafil offers a shorter window of action and is widely used. If you wish to compare brands, review Viagra® with your clinician to see which option fits your needs. For urinary symptoms of BPH, an alpha blocker may be considered. Your prescriber may discuss whether a selective agent such as Tamsulosin Cr could be appropriate, alone or alongside other therapies when safe.

Pricing and Access

Canadian pricing can lower the overall Cialis cash price compared with many local options. You can buy Cialis online from Canada through CanadianInsulin, with prompt US delivery from Canada. Many patients browse by strength to estimate total cost, such as Cialis 5mg cost, Cialis 10mg price, and Cialis 20mg price. Some shoppers look up Cialis 20mg price US shipping to plan refills. Others compare tadalafil online Canadian pricing to understand options. People sometimes research tadalafil cost out of pocket and how to purchase Cialis online using a valid prescription.

Availability and Substitutions

Availability can change. If a requested strength is not available, your prescriber may recommend an alternative strength or a different approved therapy. Do not switch medicines or doses without professional guidance.

Patient Suitability and Cost Saving Tips

Candidates include adult men with diagnosed ED, BPH, or both conditions, who are not using nitrates or guanylate cyclase stimulators. Those with significant cardiovascular disease or severe hepatic or renal impairment need individualized guidance. Cialis is not for use in women, children, or anyone without a prescription. Do not share this medicine with others.

To manage costs, consider multi-month supplies if appropriate. A 60- or 90-day fill can reduce per-dose costs and cut down on pharmacy fees. Set up refill reminders so you do not run out on travel days. Keep a photo of your prescription and your pharmacy label for easier reorders. Ask your clinician whether a daily or as-needed regimen fits your goals and budget.
