1️⃣Nitrates (Most Important)
Do NOT combine with:
Nitroglycerin
Isosorbide dinitrate / mononitrate

2️⃣ Excessive Alcohol
Avoid heavy drinking (more than 4–5 drinks).
Risks include:

Increased risk of fainting
Moderate alcohol (1–2 drinks) is usually tolerated, but caution is advised.

Vardenafil
Avanafil
Reason: Increased risk of side effects without added benefit.
4️⃣ Alpha-Blockers (Unless Medically Supervised)
Examples:

Risk: Additive blood pressure lowering effects.
5️⃣ Certain Blood Pressure Medications
Use caution with:
Strong antihypertensives
Multiple BP-lowering drugs together
Medical supervision is recommended.
6️⃣ Grapefruit & Grapefruit Juice
Grapefruit can interfere with tadalafil metabolism and may:
Increase blood levels
Raise the risk of side effects
7️⃣ CYP3A4 Inhibitors (Advanced Users)
Use caution with:
Ketoconazole
Itraconazole
Clarithromycin
Ritonavir
These can increase tadalafil concentration in the body.
