Overview of Sildenafil and Tadalafil
| Medication | Brand Name | Typical Dose | Onset Time | Duration |
|---|---|---|---|---|
| Sildenafil | Viagra | 25-100 mg | 30-60 min | 4-6 hours |
| Tadalafil | Cialis | 2.5-20 mg | 30-120 min | Up to 36 hours |
Sildenafil was the first oral ED medication, introduced in the late 1990s. Tadalafil followed, offering a longer-lasting effect. Both are now available as generics, making them more accessible and affordable.
How Do They Work? Mechanism of Action
Both drugs are PDE-5 inhibitors. PDE-5 (phosphodiesterase type 5) is an enzyme that regulates blood flow in the penis. By inhibiting PDE-5, these medications promote increased blood flow during sexual arousal, facilitating an erection.
Onset and Duration of Action
| Feature | Sildenafil | Tadalafil |
|---|---|---|
| Onset of Action | 30-60 minutes | 30-120 minutes |
| Peak Blood Concentration | ~1 hour | ~2 hours |
| Duration of Effect | 4-6 hours | Up to 36 hours |
| Food Interaction | Decreased with fatty meals | No significant effect |
- Sildenafil is best taken on an empty stomach; fatty meals can reduce effectiveness.
- Tadalafil is unaffected by food and ideal for spontaneous intimacy.
Side Effects and Safety Profiles
Both medications are generally well-tolerated. Side effects may differ slightly:

FAQ: Sildenafil vs Tadalafil
What are the side effects of sildenafil and tadalafil, and which is safer?
Both medications are well-tolerated but may cause headaches, flushing, or nasal congestion. Sildenafil can cause vision changes or dizziness, while tadalafil may lead to back or muscle pain. Neither should be used with nitrates or “poppers.” Mega Aid Compounding Pharmacy offers troche-based compounded formulations to help minimize systemic side effects while maintaining effectiveness.
Can compounded ED medications work as effectively as branded Viagra or Cialis?
Yes. Compounded medications prepared by licensed and PCAB-accredited pharmacies like Mega Aid Compounding Pharmacy can be customized in dosage, strength, and delivery form (such as troches or lozenges). These alternatives can provide comparable results with potentially fewer systemic effects, especially for patients sensitive to oral tablets.
How can Mega Aid Compounding Pharmacy help with erectile dysfunction treatment?
Mega Aid Compounding Pharmacy partners with healthcare providers to create personalized, troche-based treatments for erectile dysfunction using active ingredients like sildenafil or tadalafil. Our goal is to improve treatment adherence, minimize side effects, and ensure patient privacy with seamless prescription coordination and direct delivery.
