Cialis® (tadalafil) tablets for erectile dysfunction and BPH

What Cialis® Is and How It Works

Cialis® is the brand name for tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. It is used to treat erectile dysfunction (ED) and the signs and symptoms of benign prostatic hyperplasia (BPH). Tablets are taken by mouth as needed or once daily. Many people choose to buy cialis online for convenience and cost savings.

YouDrugstore is a licensed Canadian pharmacy based in Manitoba. Orders are reviewed by licensed pharmacists before dispensing, and we offer brand and generic medicines at Canadian prices. You can order online, and our friendly customer-service chat is available during posted office hours for help with your purchase. When supply requires, we may fill through vetted, licensed international partner pharmacies to provide authentic brands, a wider selection, and reliable pricing.

Tadalafil works by blocking PDE5, which increases cyclic GMP in smooth muscle. This relaxes blood vessels and improves blood flow to the penis for ED. In the prostate and bladder, smooth-muscle relaxation can ease urinary symptoms of BPH. For ED, Cialis® can be used as needed or daily. For BPH, it is taken once daily.

Dosage and Usage

Dosing varies by condition and dosing schedule. Follow your prescriber’s directions and the product label.

• ED, as-needed: Start with 10 mg at least 30 minutes before sexual activity. The dose may be lowered to 5 mg or increased to 20 mg based on response and tolerability. Do not take more than once per day.
• ED, once daily: Typical dose is 2.5 mg to 5 mg taken at the same time each day, without regard to sexual activity.
• BPH (with or without ED): 5 mg once daily at the same time each day.
• Hepatic or renal impairment: Lower doses or longer dosing intervals may be needed; prescribers adjust based on clinical status.

Missed dose (daily use):

• If you miss a daily dose, take it when remembered the same day.
• If it is near the next dose, skip the missed dose. Do not double.

Food and alcohol:

• Food does not meaningfully change absorption. You may take with or without food.
• Limit alcohol. Drinking too much can increase dizziness and lower blood pressure.

Storage and travel:

• Store in the original blister at room temperature (15–30°C), dry and away from heat.
• Keep out of reach of children and pets.
• When traveling, pack in hand luggage with the label intact. Avoid hot cars and bathrooms.

Benefits and Savings

Cialis® offers flexible dosing. As-needed use provides on-demand support with a long window of effect. Daily dosing supports spontaneous activity and helps urinary symptoms linked to BPH. Many users value the predictable effect and longer duration compared with some alternatives.

Ordering through YouDrugstore often means meaningful savings versus typical US pricing. Many customers see 60–80% lower costs on brand or generic options, especially when choosing multi-month supplies. Our team can set up gentle reorder reminders so you do not run short.

Side Effects and Safety

Most effects are mild and improve as the body adapts. Seek urgent care for severe reactions.

• Common: Headache, flushing, nasal congestion, dyspepsia, back pain, or muscle aches.
• Less common: Dizziness, vision color tinge, or light sensitivity.
• Serious (seek care): Chest pain, fainting, sudden vision or hearing loss, priapism (painful erection lasting more than 4 hours), allergic reaction with swelling or breathing trouble.
• Drug interactions: Never use with nitrates (for chest pain) or riociguat. Use caution with alpha-blockers; prescribers may adjust dosing and timing. Some CYP3A4 inhibitors or inducers may change tadalafil levels.
• Conditions needing care: Unstable heart disease, recent stroke or heart attack, severe liver disease, severe kidney disease, uncontrolled blood pressure. Discuss risks and benefits with a prescriber before starting therapy.
• Grapefruit: Can increase levels. Avoid or limit while on tadalafil.

Onset Time

As-needed dosing may start to work in about 30 minutes for many users. Peak effect is often reached by 2 hours. The window of effect can last up to 36 hours. With daily dosing, steady blood levels are reached after several days, supporting readiness at any time.

Compare With Alternatives

Generic tadalafil offers the same active ingredient as Cialis® at a lower price point. If cost is your main factor, consider Tadalafil and discuss with your prescriber whether the generic is right for you.

Sildenafil (Viagra) has a shorter duration of action. Many patients find it reliable for a single evening, while tadalafil offers a longer window. Compare features and talk with your clinician about fit. You can review Viagra® for a shorter-acting option.

For BPH symptom control, alpha-blockers and 5-alpha-reductase inhibitors are often used. Finasteride can reduce prostate size over months and may be combined with other agents under medical guidance. See Finasteride if long-term prostate management is being considered alongside tadalafil.

Combination Therapy

Tadalafil may be used with some blood pressure medicines and with BPH alpha-blockers, but timing and doses may need adjustment to reduce dizziness or low blood pressure. Never combine with nitrates or riociguat. People with diabetes, depression, or post-prostatectomy ED may use tadalafil alongside other therapies such as counseling, vacuum devices, or pelvic-floor therapy. Any combination plan should be guided by a prescriber familiar with your health history and current medicines.

Patient Suitability and Cost-Saving Tips

Cialis® is suited for adults diagnosed with ED, BPH, or both. A medical review helps confirm whether on-demand or daily dosing fits best. People with heart conditions or complex medication lists need careful evaluation before starting a PDE5 inhibitor.

Ways to lower out-of-pocket costs include choosing generic tadalafil, selecting a multi-month supply, and syncing refills to reduce shipping costs. You can also sign up for reorder reminders to maintain continuity. Check our current sale for offers and bulk options.
