介绍
Cialis 20 Tablet is a prescription medicine to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, which works by relaxing the blood vessels in the penis. This allows for increased blood flow during sexual stimulation, helping to achieve and maintain an erection suitable for intercourse. Cialis is taken on demand and is known for its long-lasting effect—up to 36 hours in some individuals—earning it the nickname “the weekend pill.” Its clinical reliability and well-established safety profile make it a trusted choice among healthcare providers worldwide.
Common benefits include improved erectile function, better spontaneity in intimate relationships, and overall sexual confidence. Users typically report noticeable improvement in erections within 30 to 60 minutes after taking the medication when sexually stimulated. While generally well-tolerated, some individuals may experience mild side effects such as headache, indigestion, back pain, or muscle aches. It’s important to note that Cialis does not induce automatic erections; sexual arousal is required.
一般适应症
Cialis 20mg is primarily indicated for the treatment of erectile dysfunction (also called impotence) in adult males aged 18 and over. It may also be prescribed for benign prostatic hyperplasia (BPH) and combined ED with BPH in some cases. ED affects millions of men globally and can result from various causes including stress, age, lifestyle factors, medical conditions, or medications. Cialis helps restore natural erectile response by enhancing nitric oxide’s effect during arousal.
Many international customers choose to purchase Cialis through DoctorOnCall International, a Malaysia-based licensed online pharmacy, due to its transparent sourcing, government registration, and strong regulatory standards. Ordering from a Malaysia-licensed pharmacy ensures that you receive genuine, quality-assured products at competitive prices, with the added convenience of safe international shipping. Professional pharmacist consultations are also available, ensuring secure and responsible usage.
如何服用
Cialis 20mg should be taken orally with a full glass of water, approximately 30 minutes before planned sexual activity. It can be taken with or without food, although heavy meals may slow its onset slightly. You should never take more than one tablet in 24 hours. Timing flexibility is a key advantage—Cialis has a longer active window than many other erectile dysfunction medications.
It’s best to build a consistent routine based on your lifestyle and sexual needs. Do not split or crush the tablet. Avoid alcohol consumption before taking Cialis, as it may increase the risk of side effects like dizziness. If you miss a dose of once-daily tadalafil (if recommended by your doctor), skip it if it’s almost time for your next dose—do not double up.
剂量信息
Cialis is available in several strengths: 2.5mg, 5mg, 10mg, and 20mg. The 20mg strength is intended for use prior to anticipated sexual activity, not for daily use unless directed by a doctor. For most men, a starting dose of 10mg is sufficient, but your healthcare provider may increase it to 20mg based on efficacy and tolerability.
It is essential to consult a licensed doctor before starting Cialis to receive tailored recommendations. Never self-medicate or adjust your dosage without professional guidance. If overused or taken incorrectly, tadalafil can lead to unwanted side effects or interactions.
