Sildalis (Sildenafil 100 mg + Tadalafil 20 mg) Tablets

Sildalis is the one tablet in our erectile dysfunction lineup that puts two active PDE5 inhibitors into a single dose: 100 mg of sildenafil and 20 mg of tadalafil together. That single fact changes the buying decision more than anything else about this listing. Instead of choosing between a sildenafil-only medicine and a tadalafil-only medicine, a customer looking at Sildalis must consider the safety implications of receiving both ingredients at once compared with a single-ingredient alternative such as Viagra, Levitra, or Stendra.

Because Sildalis combines two PDE5 inhibitors at doses each normally taken alone, it is not a routine starting option. Below, we compare Sildalis with relevant single-ingredient alternatives, explain how the combination acts in the body, and walk through package sizes, pricing, access, safety, ordering, and shipping for customers in the United States.

Sildalis vs. Viagra, Levitra, and Stendra: Comparing Your Options

Every PDE5 inhibitor works on the same basic pathway, but the four products below differ in active ingredient, typical onset, and duration. Those differences matter when comparing a tablet that combines sildenafil and tadalafil with a single-ingredient option.

Sildalis vs. Levitra

Levitra contains vardenafil alone, a PDE5 inhibitor with an onset and duration profile broadly similar to sildenafil. Choosing between Sildalis and Levitra involves comparing a single, well-understood ingredient with simultaneous exposure to sildenafil and tadalafil in one tablet. A qualified clinician can help determine whether any PDE5 inhibitor is appropriate in light of current medicines, blood pressure, and cardiovascular health.

Sildalis vs. Stendra

Stendra is a brand of avanafil, a single PDE5 inhibitor known for a comparatively fast onset. We do not currently stock the Stendra brand itself, though we carry Avana for customers considering avanafil rather than the two active ingredients in Sildalis. Individual response and adverse effects can differ, so speed of onset should not be the only selection factor.

Sildalis vs. Viagra

Viagra contains sildenafil citrate alone, with 100 mg representing the maximum recommended single dose for erectile dysfunction under its US labeling. Sildalis contains the same amount of sildenafil plus 20 mg tadalafil, so previous experience with Viagra does not establish that the combined tablet will be safe or suitable.

What Makes Sildalis Different

The defining feature of Sildalis is its combination of two timing profiles. Sildenafil commonly begins working within about 30 to 60 minutes and may remain effective for roughly 4 to 6 hours, while tadalafil may take longer to reach its full effect and can remain active for up to 36 hours. Putting both ingredients in one tablet creates a longer period of combined drug exposure, but it may also increase blood-pressure-lowering effects and other adverse reactions. Superior efficacy or safety compared with properly selected single-ingredient treatment has not been established.

Our Sildalis tablets are manufactured by RSM Enterprises Pvt. Ltd. and supplied at one strength: 100 mg sildenafil plus 20 mg tadalafil per oral tablet. These are the maximum recommended as-needed doses of the individual ingredients when each is used alone for erectile dysfunction, which is why the combination should not be treated as a routine first dose or added to another PDE5 inhibitor.

How Sildenafil and Tadalafil Work

Sildenafil and tadalafil are both phosphodiesterase type 5 (PDE5) inhibitors. They inhibit the enzyme that breaks down cGMP in smooth muscle, supporting increased blood flow into erectile tissue in response to sexual stimulation. Neither ingredient produces an erection without stimulation, and combining them does not create a separate or doubled biological mechanism; it exposes the same pathway to two chemically different inhibitors.

Food matters more for sildenafil than for tadalafil. A high-fat meal can delay sildenafil absorption and reduce its peak concentration, while tadalafil absorption is not meaningfully affected by food. This does not provide an established administration regimen for Sildalis, however. There is no established self-dosing schedule for this fixed combination, and it should not be taken with any other sildenafil-, tadalafil-, vardenafil-, or avanafil-containing medicine. A qualified clinician should assess whether its ingredients are appropriate before use.

Sildalis Package Sizes and Value in the US

We offer Sildalis in nine package sizes, from 10 pills up to 360 pills, all at the same 100 mg sildenafil plus 20 mg tadalafil strength. This lets customers compare quantities without switching strengths. Comparing the total price and price per pill across package sizes is the simplest way to assess whether a smaller order or a larger supply makes more sense for a given budget.

Prices are listed in US dollars, and checkout accepts Visa, Mastercard, American Express, Discover, Apple Pay, Google Pay, and cryptocurrency, including Bitcoin and USDT. Customers who buy Sildalis online in larger package sizes may see a lower per-pill cost than at the smallest 10-pill size. That potential value should be weighed against suitability, expected use, storage, and the benefit of seeking clinical advice before committing to a larger quantity.

Ordering Sildalis in the United States: Access and Regulatory Context

Access to erectile dysfunction medicines in the United States can involve cash payment, private insurance, Medicare, Medicaid, employer plans, federal medicine regulation, and state-specific pharmacy rules. Sildenafil and tadalafil are each authorized as ingredients in separate FDA-approved medicines, but the sildenafil-and-tadalafil combination in Sildalis is not authorized for human medicinal use in the United States. That ingredient-combination status is separate from the strength and package quantities offered on this page.

Our current prescription requirement for this product should be confirmed with our support team before checkout. State boards of pharmacy regulate pharmacy practice separately from FDA medicine regulation, so local requirements and access routes may differ by state. US customers may also encounter different coverage and cash-purchase arrangements at chain pharmacies, independent community pharmacies, and mail-order or online pharmacies.

Practical Use and Storage

There is no established US dosing regimen for this fixed sildenafil 100 mg and tadalafil 20 mg combination. Do not infer a suitable dose from the individual labeling of either ingredient, split or repeat doses without professional advice, or combine Sildalis with another erectile dysfunction medicine. Tadalafil remains in the body substantially longer than sildenafil, so overlapping exposure can continue into the following day even after the more noticeable sildenafil effect has declined.

• Ask a qualified clinician to review cardiovascular health, blood pressure, kidney and liver function, and all current medicines before use.
• Avoid a heavy, high-fat meal when discussing timing, because it can delay absorption of the sildenafil component.
• Do not add sildenafil, tadalafil, vardenafil, avanafil, or another PDE5 inhibitor.
• Store tablets at room temperature between 68°F and 77°F, away from moisture, heat, and direct light.

Interactions, Adverse Effects, and Safety Precautions

US labeling for sildenafil and tadalafil advises against combining either medicine with another PDE5 inhibitor because the safety and efficacy of such combinations have not been studied and additive effects may increase the risk of significant hypotension or priapism. Common adverse effects associated with the individual ingredients include headache, flushing, indigestion, nasal congestion, dizziness, back pain, muscle aches, and visual changes. Combining the ingredients may increase the frequency or intensity of some reactions.

Important interaction guidance includes:

• Nitrates and nitric oxide donors - combining these with sildenafil or tadalafil can cause a dangerous, sudden drop in blood pressure.
• Guanylate cyclase stimulators such as riociguat - these are contraindicated with PDE5 inhibitors because of the risk of symptomatic hypotension.
• Alpha-blockers and other blood-pressure medicines - these may add to blood-pressure-lowering effects and cause dizziness or fainting.
• Strong CYP3A4 inhibitors, including certain antifungal and HIV medicines, can raise sildenafil or tadalafil exposure; strong inducers may reduce exposure.
• Alcohol and grapefruit products - heavy alcohol use can worsen dizziness and hypotension, while large amounts of grapefruit may increase drug exposure.

Seek urgent medical help for chest pain, fainting, a severe allergic reaction, sudden loss of vision or hearing, or an erection lasting more than four hours. A person who develops chest pain after taking a PDE5 inhibitor should tell emergency personnel when it was taken and must not self-administer nitrate medicine.

Who Should Avoid Sildalis or Seek Medical Advice First

Sildalis must not be used with nitrates, nitric oxide donors, or riociguat, and it should be avoided by anyone with known hypersensitivity to sildenafil, tadalafil, or any tablet ingredient. Sexual activity itself can place strain on the heart, so people who have been advised to avoid sexual activity because of cardiovascular risk should not use an erectile dysfunction medicine without specialist guidance.

• Adults already using any sildenafil-, tadalafil-, vardenafil-, or avanafil-containing product should not add Sildalis.
• Sildalis is not intended for children, and its adult-strength combination is unsuitable for pediatric use.
• Safety in pregnancy and breastfeeding has not been established for this sildenafil-and-tadalafil combination.
• Anyone with cardiovascular disease, a recent stroke or heart attack, uncontrolled or unusually low blood pressure, severe liver impairment, significant kidney impairment, retinal disease, bleeding disorders, or a condition that predisposes to priapism should seek medical advice first.
• Anyone who experiences dizziness or visual changes should not drive or operate machinery until they know how the medicine affects them.

Clinical review is also important for people taking alpha-blockers, multiple blood-pressure medicines, strong CYP3A4 inhibitors, or medicines that may otherwise affect cardiovascular stability. Depending on individual risks, a clinician may favor a lower-dose, single-ingredient PDE5 inhibitor rather than simultaneous exposure to two maximum as-needed doses.

Product selection should account for current medicines, previous response, desired timing, and professional advice rather than duration alone.

Shipping and Delivery Across the United States

The United States spans enough distance and climate variation, from dry Southwest heat to Gulf Coast humidity and freezing northern winters, that shipping times and parcel handling can differ depending on the destination. We therefore treat all delivery times as estimates rather than guarantees. When you order Sildalis online with us, you can choose tracked Express shipping, generally estimated at 4 to 7 days, or Standard shipping, generally estimated at 14 to 21 days, with free shipping available above the qualifying order value shown at checkout.

Based on our experience with previous deliveries to cities such as San Diego, Nashville, Jacksonville, El Paso, and New York, many orders arrive within these ranges, although rural addresses, severe weather, carrier disruptions, and last-mile conditions can extend delivery time. Express shipping may be preferable when timing matters. After delivery, bring the parcel indoors promptly and keep the tablets away from excessive heat, humidity, and freezing conditions; they should be stored between 68°F and 77°F.
