Cialis® Uses, Dosages, and Savings From Canada

What Cialis® Is and How It Works

Cialis is a prescription phosphodiesterase type 5 (PDE5) inhibitor used for erectile dysfunction (ED) and for lower urinary tract symptoms of benign prostatic hyperplasia (BPH). It is supplied as oral tablets in strengths such as 2.5 mg, 5 mg, 10 mg, and 20 mg. Many people choose to buy cialis online for convenience and access to Canadian pricing on brand and generic options.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba, and a licensed pharmacist reviews every prescription before dispensing. We also partner with vetted international pharmacies to supply authentic brand medicines, offering a broad selection at affordable prices.

How Cialis works: sexual stimulation triggers nitric oxide release in penile tissue, which increases cyclic GMP. PDE5 breaks down cGMP. By inhibiting PDE5, Cialis helps maintain higher cGMP levels, which supports increased blood flow and an erection. For BPH, improved smooth muscle relaxation in the prostate and bladder neck can ease urinary symptoms. Cialis tablets are taken either as needed before sexual activity or once daily at a lower dose. The active ingredient is tadalafil, also available as tadalafil tablets in generic form.

Dosage and Usage

• As-needed dosing for ED: Typical starting dose is 10 mg taken at least 30 minutes before sexual activity. Doses may be adjusted to 5 mg or 20 mg based on response and tolerability. Do not take more than once per day.
• Once-daily dosing for ED: 2.5 mg to 5 mg taken at the same time each day. This supports sexual activity at any time after the first few days of consistent use.
• Dosing for BPH or ED with BPH: 5 mg once daily, taken at the same time each day. Benefits on urinary symptoms may appear after 1–2 weeks and can continue to improve over several weeks.
• Renal or hepatic impairment: Lower doses or extended dosing intervals may be recommended. Follow your prescriber’s instructions.
• Food and timing: Cialis may be taken with or without food. Avoid taking more than the prescribed dose in any 24-hour period.
• Missed dose (daily regimen): If a dose is missed, take it when remembered unless it is close to the next dose. Do not double up.
• Alcohol: Limit alcohol to reduce the risk of dizziness or low blood pressure. Heavy drinking can decrease erectile performance.
• Grapefruit: Grapefruit or grapefruit juice can raise tadalafil levels. Ask your prescriber about potential interactions.

• Storage: Store at 20–25 °C (68–77 °F). Excursions 15–30 °C (59–86 °F) are acceptable. Keep tablets dry and in the original bottle or blister.
• Moisture: Keep away from bathrooms and humidity. Close the container tightly after each use.
• Travel: Carry your medication in your hand luggage. Keep it in the labeled pharmacy container for airport screening.
• Heat and cold: Do not leave tablets in a hot car or near a heater. Avoid freezing temperatures.
• Home storage: Store out of reach of children and pets. Check the expiry date before use.

Benefits and Savings

Cialis offers flexibility. As-needed dosing works within about 30 minutes and can last up to 36 hours. The long window supports natural timing. Once-daily tadalafil daily therapy can remove the need to plan around doses. For BPH, Cialis can help reduce urinary frequency, urgency, and weak stream in many patients.

Ordering from Canada can lower your tadalafil purchase costs. You can compare cialis price options by strength, including popular doses such as cialis 5mg and cialis 20mg. Many customers see 60–80% savings versus typical U.S. prices. Generic tadalafil is often less than brand, reducing overall cialis cost.

Buying a larger supply can lower per-month costs, and multi-month packages may be priced more competitively. You can set gentle reorder reminders so you never run out. If you prefer brand over generic cialis online, you can still compare cialis 5mg price and cialis 20mg price across options before checkout. Some customers search for cheap cialis, but be sure you purchase from licensed sources.

Side Effects and Safety

• Headache
• Flushing or warmth
• Indigestion or stomach discomfort
• Nasal congestion
• Back pain or muscle aches
• Dizziness
• Limb or back discomfort
• Nausea

Serious but uncommon events include prolonged erection (priapism), sudden vision loss (including non-arteritic anterior ischemic optic neuropathy), sudden hearing loss, severe dizziness, fainting, or chest pain. Do not use Cialis with any nitrate medication (nitroglycerin, isosorbide) or with riociguat due to dangerous blood pressure drops. Use caution with alpha-blockers; doses may need to be stabilized to reduce hypotension. Ask your prescriber about cardiovascular fitness for sexual activity if you have heart disease, recent stroke or heart attack, or uncontrolled blood pressure.

Onset Time

As-needed Cialis usually begins to work in about 30 minutes, with peak effect around two hours for many users. The window of efficacy can last up to 36 hours. With once-daily dosing, steady effects generally develop after 2–5 days. For BPH, noticeable urinary symptom relief may appear in 1–2 weeks, with continued improvement up to 4 weeks.

Compare With Alternatives

Generic tadalafil provides the same active ingredient as brand Cialis at a lower cost, often improving access and adherence. You can review strengths such as Tadalafil to compare pricing and supply sizes.

Viagra (sildenafil) is another PDE5 inhibitor with a shorter duration of effect, often around 4–6 hours. Some prefer its faster onset, while others prefer the longer window of Cialis. You can compare labeling and options for Viagra®.

For BPH, non-PDE5 alternatives include alpha-blockers (e.g., tamsulosin) and 5-alpha-reductase inhibitors such as finasteride. These differ in onset and side-effect profiles, and they do not treat ED. Some patients use tadalafil together with other BPH therapies under medical supervision.

Combination Therapy

• ED with daily tadalafil: Continue 2.5–5 mg daily and avoid additional as-needed doses unless advised by your prescriber.
• With alpha-blockers: Stabilize the alpha-blocker first at the lowest effective dose. Introduce tadalafil cautiously to reduce dizziness or low blood pressure.
• With 5-alpha-reductase inhibitors for BPH: Tadalafil 5 mg daily may be used alongside finasteride when directed by your prescriber.
• With antihypertensives: Monitor for additive blood pressure lowering. Report symptoms like lightheadedness.
• Avoid: Nitrates and riociguat with any tadalafil dose; potent CYP3A4 inhibitors may require dose adjustments.

Patient Suitability and Cost-Saving Tips

Cialis may be suitable for adult men with ED, and for adults with BPH symptoms such as frequency, urgency, or slow stream. It is not indicated for use in women or children. People with recent heart attack or stroke, severe liver disease, uncontrolled blood pressure, or those taking nitrates should not use Cialis. Those with anatomical penile changes or conditions that predispose to priapism should use caution.

To save on therapy, compare brand and generic cialis medication options before checkout. Consider tadalafil tablets in multi-month supplies to reduce shipping fees and monthly costs. Per-tablet pricing often improves with larger quantities. You can order cialis online or purchase cialis online after your prescriber provides a valid cialis prescription. If you prefer support by phone during office hours, our team can help complete your order.
