TADALAFIL TABLETS 20MG ( GENERIC CIALIS 20 MG )

What is Tadalafil 20 mg?

Tadalafil Tablets 20 mg (Generic Cialis 20 mg) treat erectile dysfunction (ED) in adult men. Tadalafil is a PDE-5 inhibitor that increases penile blood flow during sexual stimulation, helping achieve and maintain an erection.

• Form: Oral, film-coated tablet

• Strength: Tadalafil 20 mg

• Typical users: Adult men 18+ after medical evaluation

• Not for: Women or anyone under 18

How tadalafil works

Tadalafil blocks PDE-5, preserving cGMP in penile tissue. This relaxes smooth muscle and improves blood flow when sexual stimulation is present.

• Onset: ~30–60 minutes

• Duration: up to 36 hours (varies)

• Food effect: Minimal; can be taken with or without food

Dosage and directions

Use only as directed by a licensed clinician.

• As-needed dosing: 10–20 mg at least 30–60 minutes before sex; do not exceed 1 dose in 24 hours

• Daily low-dose option: 2.5–5 mg once daily for frequent sexual activity (not the 20 mg strength)

• Swallow whole with water. Avoid excessive alcohol (may increase dizziness and lower BP).

Who should not use tadalafil 20 mg

Do not use if you:

• Are allergic to tadalafil or tablet components

• Take nitrates (e.g., nitroglycerin) or riociguat

Tell your clinician before use if you have:

• Heart disease, recent heart attack or stroke, uncontrolled blood pressure

• Severe liver or kidney impairment (dose adjustments or avoidance may be required)

• Eye diseases (e.g., retinitis pigmentosa) or prior sudden vision loss (NAION)

• Blood disorders predisposing to priapism (sickle cell anemia, leukemia, multiple myeloma)

• Anatomical penile deformity (e.g., Peyronie’s disease)

Drug and food interactions

• Contraindicated: Nitrates, riociguat

• CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir/cobicistat) ↑ tadalafil levels—dose changes or avoidance may be needed

• CYP3A4 inducers (e.g., rifampin) ↓ effectiveness

• Antihypertensives/alpha-blockers: additive BP lowering; spacing/monitoring may be required

• Alcohol: enhances hypotension/dizziness

• Grapefruit: may increase levels; avoid

Possible side effects

Serious—seek urgent care:

• Priapism (erection >4 hours)
