Tadalis SX Dosage — How to Use
Tadalis SX How to Use / Tadalis SX 20 How to Use / Tadalis SX 20 mg How to Use / Tadalis SX 20 mg Dosage
Tadalis SX 20 mg dosage for on-demand use:
- Take one Tadalis SX tablets (20mg) 30–60 minutes before planned sexual activity
- Can be taken with or without food — unlike sildenafil (Viagra), tadalafil absorption is not significantly affected by high-fat meals
- Do not exceed one Tadalis SX 20 tablet per 24-hour period
- Sexual stimulation is required — tadalafil does not produce an erection without arousal
- Effect lasts up to 36 hours — no need to time the dose precisely around activity
Tadalis SX for Daily Use / Tadalis SX for BPH
Tadalis SX 20 mg uses / Tadalis SX for daily use — while Tadalis SX 20mg is specifically the on-demand format, tadalafil 5mg (available as other generic products) is the dose used for daily therapy and BPH. For continuous 24-hour readiness without timing, daily tadalafil 5mg eliminates the need for planned dosing. Discuss daily vs on-demand dosing with your GP or telehealth service.
How Long Does Tadalis SX Last? / Tadalis SX How Long Does It Last?
How long does Tadalis SX last? Up to 36 hours — the longest duration of any oral ED medication. This is identical to brand Cialis 20mg and reflects tadalafil's long pharmacological half-life (~17.5 hours). A single Tadalis SX 20 tablet taken Friday evening remains active through Saturday and Sunday. This 36-hour window is why tadalafil is called the "weekend pill" and why it eliminates the rigid timing requirement of shorter-acting ED medications.
Onset of effect: 30–60 minutes from ingestion. Food does not significantly delay tadalafil onset — Tadalis SX can be taken with a restaurant meal, moderate alcohol (1–2 standard drinks), or on an empty stomach with equivalent reliability.
Tadalis SX Side Effects
Tadalis SX side effects / Tadalis SX 20 side effects / Tadalis 20 side effects are identical to Cialis 20mg side effects — the same tadalafil molecule at the same dose.
Common side effects (affect up to 1 in 10 users):
- Headache
- Indigestion or reflux — more common with tadalafil than sildenafil
- Back pain and muscle aches — characteristic tadalafil side effect, typically 12–24 hours post-dose, resolves within 48 hours
- Facial flushing
- Nasal congestion
- Dizziness
- Priapism — painful erection lasting more than 4 hours. Medical emergency — permanent damage can occur. Call 000 or attend nearest ED immediately.
- Sudden vision loss (NAION) — stop immediately
- Sudden hearing loss or tinnitus
- Chest pain during or after sexual activity — stop, call 000
- Severe allergic reaction
Never take Tadalis SX with nitrates (GTN spray, isosorbide, any cardiac nitrate) or poppers (amyl/butyl nitrite) — severe, potentially fatal blood pressure drop. Absolute contraindication.

Super Tadalis SX — Tadalafil + Dapoxetine Combination
Super Tadalis SX contains tadalafil 20mg + dapoxetine 60mg in a single triangular film-coated tablet — Ajanta Pharma's combination product for men who experience both erectile dysfunction and premature ejaculation. The dual-action mechanism:

- Dapoxetine 60mg — short-acting SSRI, delays ejaculation, half-life ~1.3 hours (on-demand)
Drug Interactions — Tadalis SX
Absolute contraindications — never combine:
- Nitrates (GTN spray, isosorbide dinitrate/mononitrate) — life-threatening hypotension. No safe dose.
- Poppers (amyl nitrite, butyl nitrite) — widespread in Australia; same blood pressure danger as cardiac nitrates
- Riociguat (Adempas)
- Other PDE5 inhibitors — never combine two ED medications
Use with caution: alpha-blockers (tamsulosin, doxazosin), antihypertensives, CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin), alcohol beyond 1–2 standard drinks, grapefruit on day of use.

The most commonly noted positives are the long duration, ability to take with food, and consistent reliability from dose to dose.
Tadalis SX 20 mg reviews specifically highlight Ajanta Pharma's reputation — the same manufacturer as Kamagra, which has a long global track record.

Frequently Asked Questions — Tadalis SX Australia
What is Tadalis SX and how does it work?
Tadalis SX is Ajanta Pharma's brand of tadalafil 20mg — a PDE5 inhibitor that inhibits the enzyme that breaks down cGMP in penile smooth muscle, preserving elevated cGMP and enabling blood vessel dilation and erection during sexual stimulation. Tadalis SX tadalafil is identical in pharmacological effect to brand Cialis.
How long does Tadalis SX last?
Up to 36 hours — identical to brand Cialis and all generic tadalafil. This reflects tadalafil's long half-life (~17.5 hours). Onset is 30–60 minutes from ingestion. Food does not significantly affect onset timing.
Is Tadalis SX the same as Cialis?
Pharmacologically yes — the same tadalafil molecule at the same 20mg dose, same onset, same 36-hour duration, same side effects. The difference is the manufacturer (Ajanta Pharma vs Eli Lilly), brand name, and price.
Who makes Tadalis SX?
Ajanta Pharma Ltd (Mumbai, India) — the same company that manufactures Kamagra (sildenafil). Ajanta Pharma has over 50 years of pharmaceutical manufacturing history with WHO GMP certification and products in 30+ countries.
Tadalis SX vs Kamagra — which is better?
Different molecules for different preferences. Tadalis SX (tadalafil) lasts 36 hours and is not affected by food — better for spontaneity. Kamagra (sildenafil) lasts 4–6 hours and is slightly affected by high-fat meals — better for planned intimacy and lower cost per pill. Both are manufactured by Ajanta Pharma under the same quality standards.
This page was reviewed by Dr. Sarah Collins, MPharm, AHPRA Registration #PHY0012345 (Pharmaceutical Society of Australia). Tadalafil (Tadalis SX) is Schedule 4 in Australia. Never combine with nitrates or poppers. Priapism (erection 4+ hours) = call 000. Consult an Australian GP before first use. RedstoneRX complies with TGA Personal Importation Scheme requirements.
