Cialis 20 mg (Tadalafil)
Cialis contains tadalafil, a long-lasting PDE5 inhibitor best known for erectile dysfunction. Tadalafil is also used daily for symptoms associated with benign prostatic hyperplasia (BPH), and low-dose tadalafil has also been discussed for improving blood flow to the scalp.
Each Thai Anabolics bottle contains 50 tablets with 20 mg tadalafil per tablet.
Cialis Dosage – Keep It Simple
| What Are You Using It For? | Common Dose |
|---|---|
| Erectile Dysfunction – As Needed | 10–20 mg before sex |
| Daily ED Support | 2.5–5 mg daily |
| Prostate / BPH Symptoms | 5 mg daily |
| Hair / Scalp Blood Flow – Off-Label | 5 mg daily |
For Erectile Dysfunction
If you are using Cialis as needed for erectile dysfunction, tadalafil is normally taken before sexual activity.
The standard prescribing information starts at 10 mg and allows the dose to be increased to 20 mg or reduced to 5 mg depending on effectiveness and tolerability.
Since the Thai Anabolics tablet contains 20 mg, one full tablet is the upper commonly prescribed as-needed dose.
Do not take more than one 20 mg tablet within 24 hours.
For Daily Erectile Dysfunction Support
Men who prefer continuous coverage instead of taking Cialis only before sex commonly use a lower daily dose.
The established daily tadalafil dose for ED is 2.5 mg once daily, which may be increased to 5 mg daily.
Daily tadalafil is taken at approximately the same time each day and does not need to be timed around sexual activity.
For Prostate / BPH Symptoms
Tadalafil is also approved for treating the signs and urinary symptoms associated with benign prostatic hyperplasia (BPH).
The established dose for BPH is:
5 mg once daily.
Low-dose tadalafil is frequently discussed for prostate health because it can improve urinary symptoms associated with an enlarged prostate while also supporting erectile function.
It is more accurate to say tadalafil improves the symptoms of BPH rather than simply claiming that Cialis physically shrinks the prostate.
Cialis for Hair and Scalp Blood Flow
Low-dose tadalafil has also attracted attention as an off-label hair and scalp-blood-flow strategy.
Andrew Huberman has discussed low-dose tadalafil as one method of increasing blood flow to the scalp and supporting the environment around hair follicles. Doses around 5 mg per day have been discussed in this context.
However, hair growth is not an approved indication for tadalafil, and the clinical evidence for tadalafil itself as a hair-loss treatment is much less established than the evidence supporting its use for erectile dysfunction and BPH.
When Should You Take Cialis?
For erectile dysfunction, tadalafil can be taken approximately 30 minutes before sexual activity.
Unlike sildenafil/Viagra, tadalafil has a very long duration of action. Erectile-function benefits have been demonstrated for up to approximately 36 hours after a dose.
This does not mean you will have an erection for 36 hours. Sexual stimulation is still required.
For daily use, simply take the dose at approximately the same time each day.
Cialis vs Viagra
| Feature | Cialis / Tadalafil | Viagra / Sildenafil |
|---|---|---|
| Typical Duration | Up to 36 hours | Usually much shorter |
| Daily Low-Dose Option | Yes | Not typically used this way for ED |
| BPH Use | Yes | No standard BPH indication |
| Food | Can be taken with or without food | Heavy meals can affect onset |
The main reason many men prefer Cialis is simple: you do not have to time sex as closely around the tablet.
Can You Take Cialis With Food?
Yes.
Tadalafil can be taken with or without food.
Can You Drink Alcohol With Cialis?
Yes, but don’t overdo it.
Both tadalafil and alcohol can lower blood pressure. Heavy alcohol consumption while taking Cialis can increase the chance of dizziness, headache, increased heart rate and a drop in blood pressure.
A few drinks is very different from heavy drinking. The official tadalafil prescribing information specifically warns about substantial alcohol consumption.
Common Cialis Side Effects
Common tadalafil side effects can include:
- Headache
- Indigestion
- Back pain
- Muscle aches
- Flushing
- Nasal congestion
Most side effects are temporary, but persistent or severe symptoms should be assessed by a medical professional.
Important: Do Not Combine Cialis With Nitrates
Do not use tadalafil with nitrate medications.
This includes medicines containing nitroglycerin, isosorbide dinitrate or isosorbide mononitrate, as well as recreational nitrate drugs commonly called “poppers.”
The combination can cause a dangerous drop in blood pressure.
Tadalafil can also interact with some alpha-blockers, blood-pressure medications and strong CYP3A4 inhibitors, so medication interactions should be checked before use.
