Intimacy plays an important role in emotional connection and self-confidence, but erectile dysfunction (ED) can quietly disrupt both. Many men experience erection difficulties at some point in life, and while it can feel isolating, ED is actually a very common medical condition. It does not reflect a lack of masculinity or desire, it simply means the body may need medical support.
Erectile dysfunction is defined as the persistent difficulty in achieving or maintaining an erection firm enough for sexual activity. It can occur due to physical causes such as diabetes, high blood pressure, cardiovascular disease, or hormonal changes, as well as psychological factors like stress, anxiety, or performance pressure.
Sildalis is one of the medications prescribed to help manage erectile dysfunction. It is often discussed alongside well-known ED treatments because it combines two established active ingredients used in branded medications. In this article, we’ll explain what Sildalis is, how it works, how it’s taken, potential side effects, safety considerations, and answers to common questions, so you can make informed decisions in consultation with your healthcare provider.
What Is Sildalis, and How Does It Work?
What Is Sildalis?
Sildalis 120mg is a prescription medication used to treat erectile dysfunction in adult men. It is unique in that it combines two active ingredients commonly used in ED treatment:
- Primary medical use: Erectile dysfunction
- Active ingredients: Sildenafil citrate + Tadalafil
- Drug class: Phosphodiesterase type 5 (PDE-5) inhibitors
Sildalis is often positioned as a generic combination alternative to branded ED medications. By combining sildenafil and tadalafil, it is designed to provide both reliable onset and extended duration when used appropriately under medical guidance.
How Does Sildalis Work? (Step-by-Step)
Sildalis 120mg supports the body’s natural erectile response. It does not create sexual desire and does not cause an automatic erection. Sexual stimulation is still required. Here’s how it works:
- Sexual stimulation occurs
Sexual arousal triggers chemical signaling in the body. - Nitric oxide (NO) is released.
During arousal, nitric oxide is released in the penile tissues. - cGMP levels increase
Nitric oxide increases levels of cyclic guanosine monophosphate (cGMP), a chemical messenger. - Blood vessels relax
cGMP helps relax smooth muscles in the blood vessels of the penis. - Blood flow improves
Relaxed blood vessels allow increased blood flow into the penis. - Erection is supported
Improved blood flow helps achieve and maintain an erection during sexual activity.
Sildalis works by inhibiting the PDE-5 enzyme, which normally breaks down cGMP. By slowing this breakdown, Sildalis helps maintain adequate blood flow, but only in the presence of sexual stimulation. It does not increase libido and does not act as an aphrodisiac.
Other Medical Uses (If Applicable)
While Sildalis itself is prescribed for erectile dysfunction, its individual components have additional medical uses:
- Sildenafil is used at different doses to treat pulmonary arterial hypertension (PAH).
- Tadalafil may also be prescribed for benign prostatic hyperplasia (BPH) and PAH at specific doses.
Important notes:
- These conditions require different dosing and strict medical supervision.
- Sildalis for ED should not be used for other conditions unless explicitly prescribed for that purpose.
Always follow your doctor’s instructions regarding the intended use of any medication.
Dosage and Administration
Dosage
Sildalis is available in specific combination strengths depending on the formulation and region.
- Typical formulation: Sildenafil 100 mg + Tadalafil 20 mg (may vary by manufacturer)
- Typical use: As prescribed by a healthcare provider
- Onset of action: Usually within 30–60 minutes
- Duration of effect: May last up to 24–36 hours due to tadalafil’s longer action

Taking more than the prescribed dose does not improve effectiveness and significantly increases the risk of side effects.
