About Cialis
Cialis (generic name tadalafil) is a prescription tablet used mainly to treat erectile dysfunction (ED) and the urinary symptoms of benign prostatic hyperplasia (BPH). It belongs to the phosphodiesterase-5 (PDE-5) inhibitor class, a group of drugs that improve blood flow to the penis and relax smooth muscle in the prostate and bladder neck. In Singapore the medication is approved for adult men, and it is available in several strengths ranging from 10 mg to 80 mg. Although its primary label focuses on sexual health and urology, clinicians sometimes consider it for other conditions where enhanced vascular response may be beneficial.
What is Cialis?
Cialis is the brand name for a tablet containing the active ingredient tadalafil. First approved by the U.S. Food and Drug Administration in 2003, the product is marketed worldwide by Eli Lilly. In Singapore the drug is listed on the Health Sciences Authority’s register as a prescription-only medicine. Generic versions containing the same amount of tadalafil are sold under various trade names, offering a cost-effective alternative that meets the same bio-equivalence standards set by regulatory agencies.
Pharmacologically, tadalafil is classified as a selective PDE-5 inhibitor. By blocking the enzyme that normally degrades cyclic guanosine monophosphate (cGMP), the drug allows cGMP to accumulate in the smooth-muscle cells of the corpora cavernosa and the lower urinary tract. This biochemical shift translates into prolonged vasodilation and muscle relaxation, which underpin its therapeutic actions.
How Cialis Works
When a man is sexually aroused, nitric oxide is released from nerve endings in the penis. Nitric oxide activates an enzyme that produces cGMP, a messenger that relaxes the smooth muscle surrounding the erectile tissue. In the presence of normal PDE-5 activity, cGMP is rapidly broken down, causing the erection to subside. Tadalafil binds to the catalytic site of PDE-5 and prevents it from hydrolyzing cGMP. The resulting rise in cGMP levels sustains smooth-muscle relaxation, allowing blood to fill the corpora cavernosa and maintain an erection sufficient for sexual activity.
The pharmacokinetic profile of tadalafil distinguishes it from other PDE-5 inhibitors. After oral administration, peak plasma concentrations occur within 2 hours, but the drug’s half-life is about 17.5 hours. This prolonged elimination phase explains why a single dose can support sexual activity for up to 36 hours-a characteristic that has earned the nickname “the weekend pill.” Metabolism occurs primarily via the cytochrome P450 3A4 pathway, with renal and biliary excretion of metabolites modestly delay absorption, but it does not markedly affect overall exposure.
Why Cialis is Used for Sexual Health and Urology Conditions
-
Erectile Dysfunction (ED): The central problem in ED is insufficient arterial inflow or premature venous outflow in the penis. By preserving cGMP, tadalafil restores the balance between inflow and outflow, enabling a reliable erection when sexual stimulation occurs. Large, placebo-controlled trials have demonstrated that men receiving tadalafil achieve successful intercourse significantly more often than those on placebo, with response rates improving across all tested doses.
-
Benign Prostatic Hyperplasia (BPH): Enlarged prostate tissue can compress the urethra, causing urgency, weak stream, and nocturia. Tadalafil’s smooth-muscle relaxant effect extends to the prostate and bladder neck, reducing pressure on the urethra and improving urinary flow. Clinical studies that enrolled men with concurrent ED and BPH reported simultaneous improvements in International Prostate Symptom Score (IPSS) and erection quality, supporting its dual-indication label.
-
Combination of ED and BPH: For men suffering from both conditions, a single medication simplifies therapy. The ability to address sexual function and lower urinary tract symptoms with one tablet avoids polypharmacy and may improve adherence.
Guidelines from the American Urological Association and the Singapore Urological Society list tadalafil as a first-line oral agent for both ED and BPH, reflecting its favorable efficacy-to-side-effect ratio and convenient dosing flexibility.
Off-Label and Investigational Uses of Cialis
Although not approved for these indications, some clinicians explore tadalafil in other vascular-related settings:
-
Pulmonary arterial hypertension (PAH): Small pilot studies suggest that PDE-5 inhibition can reduce pulmonary artery pressure, though larger trials have favored other agents. Off-label use is reserved for patients who cannot tolerate standard therapies and must be supervised by a specialist.
-
Raynaud’s phenomenon: By promoting vasodilation in peripheral vessels, tadalafil may lessen the frequency of digital ischemic attacks. Evidence remains limited to case series, so routine use is not recommended.
-
Female sexual arousal disorder: Early-phase investigations have evaluated tadalafil’s effect on genital blood flow in women. Results are mixed, and the medication is not authorized for this purpose.
Off-label use only under qualified healthcare provider supervision.
Is Cialis Right for You?
Cialis is appropriate for adult men who experience consistent difficulty achieving or maintaining an erection, or who have bothersome urinary symptoms due to BPH. Ideal candidates are generally in good cardiovascular health, as the drug requires adequate blood flow to be effective. Men with uncontrolled hypertension, recent myocardial infarction, or severe heart failure should discuss alternatives with their physician because the vasodilatory effect can impose additional cardiac strain.
Patients taking nitrates (e.g., nitroglycerin) for chest pain must avoid tadalafil, as the combined vasodilation can precipitate profound hypotension. Those using certain antihypertensive agents, alpha-blockers, or potent CYP 3A4 inhibitors (such as ketoconazole) may need dose adjustments or closer monitoring.
Renal or hepatic impairment modestly prolongs tadalafil clearance; clinicians often start at a lower dose in these populations. For men over 65 years, the safety profile remains comparable to younger adults, provided comorbidities are managed.
In summary, if you have no contraindicating cardiovascular conditions, are not using interacting medications, and your primary concern lies within the domains of ED or BPH, tadalafil is a scientifically justified option.
Taking Cialis Effectively
To maximise benefit, ingest the tablet whole with water, preferably at least 30 minutes before sexual activity. Because the drug’s effect persists for many hours, timing can be flexible; some men choose a daily low-dose regimen to maintain steady plasma levels, while others use an on-demand approach. Food does not significantly alter absorption, but a very high-fat meal may delay onset by up to an hour-plan accordingly.
If a dose is missed simply resume the regular schedule. For daily dosing, maintain consistent timing each day to avoid peaks and troughs. Alcohol in moderate amounts does not interfere with the pharmacology, but excessive consumption can exacerbate blood-pressure reductions and impair erection quality.
Adherence improves when the medication is incorporated into a routine-setting an alarm, linking intake to a regular habit (e.g., brushing teeth), or using a pill-organiser can prevent accidental omissions. When traveling, store the tablets at room temperature away from moisture, and keep them in their original blister pack to protect potency.
Understanding Side Effects and How to Manage Them
The most frequently reported sensations-headache, flushing, and mild back discomfort-arise because tadalafil dilates blood vessels beyond the genital region. Headaches reflect cerebral vasodilation, while flushing results from increased cutaneous blood flow. Back or muscle aches are thought to stem from smooth-muscle relaxation in the spine’s vascular supply.
These effects are usually transient, resolving within a few hours. Over-the-counter analgesics (e.g., acetaminophen) can alleviate mild headache or muscle pain. Staying hydrated and avoiding excessive heat exposure may reduce flushing.
More serious concerns, such as sudden vision loss, prolonged erection lasting longer than four hours, or severe dizziness, signal rare but critical complications. If an erection persists beyond that window, prompt medical attention is required to prevent tissue damage. Sudden visual disturbances could indicate non-arteritic anterior ischemic optic neuropathy; immediate ophthalmologic evaluation is warranted.
Should you experience any symptom that feels abnormal or worsening, contact your healthcare provider promptly. They can assess whether the reaction is medication-related or requires a different therapeutic approach.

Frequently Asked Questions
-
How long after taking Cialis can I expect an erection? Peak plasma levels appear within 2 hours, but the drug’s effect can support sexual activity for up to 36 hours. Most men report noticeable improvement within an hour, especially when sexual stimulation occurs.
-
Can I take Cialis with alcohol? Moderate alcohol consumption does not negate the drug’s efficacy, but heavy drinking may lower blood pressure and diminish erection quality. It is safest to limit intake to a standard drink or two.
-
Is daily low-dose Cialis as effective as on-demand dosing? Clinical trials have shown that a 2.5 mg or 5 mg daily regimen provides consistent erectile function without the need for timing each sexual encounter. The choice between daily and as-needed dosing depends on personal preference and lifestyle.
-
Will Cialis cure my erectile dysfunction? Tadalafil treats the physiological component of ED by enhancing blood flow. It does not address underlying psychological or hormonal causes, so a comprehensive evaluation may still be necessary.
-
Can I use Cialis if I have high blood pressure? Men with controlled hypertension often take tadalafil safely. However, those with untreated or severe hypertension should obtain medical clearance before starting therapy.
-
What should I do if I miss a dose in a daily regimen? Skip the missed tablet and continue with the next scheduled dose. Do not double-dose to “make up” the missed amount, as this can increase the risk of side-effects.
-
Is there a risk of dependence on Cialis? Physical dependence has not been reported. Psychological reliance can occur if the medication becomes associated with sexual confidence; discussing expectations with a healthcare professional can mitigate this concern.
-
How does Cialis differ from other ED drugs like Viagra? Tadalafil’s longer half-life grants a wider therapeutic window, allowing more spontaneity. Sildenafil, by contrast, peaks faster but wears off within 4-6 hours. Choice often hinges on personal timing preferences and side-effect tolerance.
-
Can I use Cialis for premature ejaculation? Some physicians prescribe low-dose tadalafil off-label to improve ejaculatory control, based on its ability to prolong the erection phase. Evidence remains limited, so this use should be guided by a specialist.
-
Will I need regular blood tests while on Cialis? Routine monitoring is not required for most patients. Individuals with liver or kidney disease, or those on interacting medications, may need periodic labs to ensure safe drug levels.
