Cialis 20 mg or daily tadalafil
For erectile dysfunction, Cialis 20 mg is an as-needed treatment. Daily Cialis 5 mg follows a different schedule. Start with the dose and schedule on your prescription when comparing tablet prices.
Cialis contains tadalafil, which helps increase blood flow to the penis during sexual stimulation by blocking the enzyme PDE5. It supports an erectile response when you’re sexually stimulated.
The US tablet strengths are 2.5, 5, 10 and 20 mg. A prescriber selects the strength and schedule; the higher-strength tablet isn’t an upgrade to a daily prescription.
| Prescribed use | Dose and schedule | Practical distinction |
|---|---|---|
| As-needed erectile dysfunction | 10–20 mg before sexual activity | 10 mg is the usual starting dose; the prescriber selects it |
| Daily erectile dysfunction | 2.5–5 mg at the same time each day | A lower-dose daily schedule |
| Enlarged prostate symptoms, with or without ED | 5 mg once daily | Treatment for BPH or combined ED/BPH symptoms |
Tadalafil also treats symptoms of benign prostatic hyperplasia, or an enlarged prostate, such as a weak urinary stream and frequent urination. That daily treatment has its own prescription purpose.
Generic Cialis means generic tadalafil. FDA-approved generics provide the same clinical benefit and risks as their brand counterparts and must have the same strength, dosage form and route.
For an oral-tablet prescription, the generic choice keeps that form and prescribed strength.
Generic tadalafil is generally less expensive than branded Cialis.
You can discuss generic tadalafil as a way to lower cost while keeping the strength and schedule on your prescription.
Getting a tadalafil prescription
Yes, you can get a Cialis prescription through an online assessment and then buy Cialis online if treatment is approved. Both branded Cialis and generic tadalafil require a valid US prescription; neither is available over the counter.
If you don’t have a prescription, the assessment commonly starts with a questionnaire about your age, symptoms, blood pressure and health history. Have your current medicine list ready, including prescription drugs, over-the-counter products, supplements and herbal medicines.
A licensed clinician reviews those answers and may follow up by secure message, telephone or video. Review the full medicine list with the clinician or pharmacist, including products taken only occasionally, because interactions can change the treatment choice or dose.
The clinician decides whether tadalafil is appropriate and what to prescribe. Paying for an assessment doesn’t guarantee approval.
You can also discuss treatment with your existing prescriber or a local clinician; an online consultation is one access route, rather than a requirement for using a delivery pharmacy.
Cialis price and total charges
HealthWarehouse lists a Cialis price of about $220 for three branded 20 mg tablets (roughly $74 each), on a retail basis.
No coupon or insurance adjustment is displayed in that listing. These are as-needed tablets, so the quantity has no fixed number of days of supply.
For a lower-cost Cialis option, generic tadalafil is generally less expensive, although the amount you pay depends on the prescribed order. Compare quotes for the same strength and tablet quantity before deciding what you can afford.
The medication charge may be only part of the bill. A visit or subscription can be charged separately, and any fulfillment charge also belongs in the total.
Before payment, get a complete quote that identifies the tablets and quantity, any assessment or recurring charge, and any applicable delivery charge.
For an existing prescription, the useful comparison is the cash price, your insurance price and any eligible discount price for the same prescribed order.
Keep the strength, tablet quantity and brand or generic choice consistent across those quotes. Otherwise, a lower headline amount may be buying a different quantity or product.
If you’re paying for Cialis without insurance, a savings card or online discount may reduce the out-of-pocket charge. Ask the pharmacy which discounts apply and ask your plan about coverage and eligibility before choosing a payment route.
Strength, quantity, pharmacy and brand choice all affect cost, alongside insurance and discount eligibility. A general cost advantage for generic tadalafil doesn't establish the saving on your particular prescription.
Use the complete order total to decide whether a payment route fits your budget, including any recurring service charge that continues between fills.
Tadalafil delivery or local pickup
Home delivery brings prescribed tadalafil to you; local pickup lets you collect it from a pharmacy with stock available. An online Cialis prescription can be sent to a local pharmacy, and same-day pickup depends on that pharmacy’s availability.
If you already have a prescription, have it sent to the pharmacy that will fill it.
If you’re using telehealth, the clinician who assesses you and the pharmacy that fills the order may be separate organizations. Find out which pharmacy will dispense the tablets before selecting fulfillment.
Local pickup can suit someone who wants to collect the order rather than wait for a shipment. The pharmacy still needs the prescription and the prescribed product in stock.
For same-day pickup, the pharmacy needs both your prescription and stock.
Some online services offer Cialis delivery in discreet packaging. Confirm that delivery is available for your order and how it will be packaged if privacy at home matters to you.
Choose between collection and delivery based on the actual fulfillment arrangement, rather than assuming an online assessment automatically includes shipment.
Ask how the pharmacy accepts the prescriber’s order before forwarding documents yourself. Some dispensing pharmacies reject prescriptions faxed or emailed by patients, so the clinician may need to send the prescription directly through an accepted route.
Verify the dispensing pharmacy
Before buying tadalafil online, use FDA BeSafeRx to find your state board of pharmacy license database. Look up the pharmacy filling your prescription. If it isn’t listed, don’t use it.
The name to look up is the pharmacy filling the prescription. A telehealth service may arrange the assessment while another business supplies the medicine. Get the dispensing name so that the database search concerns the organization handling your tablets.
FDA’s safe-pharmacy criteria include requiring a valid prescription, having a US contact presence and making a licensed pharmacist available to answer questions. These give you a way to discuss the prescribed medicine and resolve a problem with the order.
The pharmacy should also provide clear written protections for your personal and financial information. Read those protections before entering health details or payment information, especially when the assessment and dispensing take place through different services.
Unsafe internet pharmacies can sell counterfeit, unapproved or otherwise unsafe medicines outside licensed-pharmacy safeguards. A polished website or a familiar-looking tablet is insufficient reassurance.
Keep the dispensing pharmacy’s details with your order.
When tadalafil works
For as-needed use, tadalafil is usually taken at least 30 minutes before sexual activity and can improve erectile response for up to 36 hours. Sexual stimulation is needed. An erection doesn’t last that whole time.
An effect lasting up to 36 hours doesn't change your prescribed dosing interval.
As-needed tadalafil is usually taken no more often than once every 24 hours. Some prescriptions require longer intervals because of interacting medicines or kidney impairment. Follow the interval on your own prescription even if the timing of sexual activity changes.
The time tadalafil takes to work can vary from person to person.
Taking tadalafil tablets
Swallow conventional tadalafil tablets whole, with or without food. Don’t split, break, chew or crush this formulation; a chewable or another formulation has its own handling directions.
Follow the prescribed dose and interval. Don’t increase the amount or take it more often on your own, and don’t turn an as-needed prescription into a daily schedule.
If a tablet strength seems unsuitable for the directions you were given, have the pharmacist resolve that before taking it.
For daily treatment, take a forgotten dose when you remember unless it’s nearly time for the next one. If the next dose is near, skip the missed dose and continue with the prescribed schedule.
Don’t double up. Never take more than one dose per day to make up for a missed daily tablet.
The missed-dose advice applies to regular daily treatment. For an as-needed prescription, use the prescribed interval and the instructions for sexual activity, rather than borrowing the daily schedule because a planned dose was missed.
Tadalafil interactions
Don’t take tadalafil with riociguat. Cialis interactions can also require a lower dose or a longer gap between tablets, so an existing 20 mg prescription may need to change when another medicine is added.
Don’t combine tadalafil with another tadalafil product or an erectile dysfunction medicine such as sildenafil or vardenafil unless your clinician directs treatment. Discuss grapefruit and grapefruit juice with your clinician too. They can increase side-effect risk.
Alpha blockers and blood-pressure medicines can add to tadalafil’s blood-pressure-lowering effect. For erectile dysfunction, the Cialis label calls for stable alpha-blocker treatment before starting Cialis at the lowest recommended dose.
For BPH, the tadalafil label doesn't recommend combining it with alpha blockers because of blood-pressure risk and insufficiently studied benefit.
With potent CYP3A4 inhibitors such as ketoconazole or ritonavir, the tadalafil label requires lower doses and, for as-needed use, longer intervals. A prescriber needs to reassess a 20 mg order before you use it with either medicine.
Heavy alcohol use adds risk. The tadalafil label gives 5 glasses of wine or 5 whiskey shots as examples of excessive intake; these examples are warnings, not a safe allowance for smaller amounts.
When 20 mg needs reassessment
Kidney or liver disease can change a tadalafil 20 mg prescription, and a known serious tadalafil allergy rules out its use. Tell the clinician about heart disease, blood-pressure problems, previous vision loss, penile abnormalities and conditions that predispose to prolonged erections.
Severe kidney impairment, including dialysis, requires a lower as-needed dose and a longer interval under the tadalafil label. Kidney impairment or liver disease means a 20 mg order needs clinician reassessment; the label doesn't recommend tadalafil for severe liver disease.
Cialis for erectile dysfunction or BPH is not indicated for children and isn't approved for females. Whether it passes into human breast milk is unknown. These product limits should stay separate from tadalafil treatment for other indications.
When tadalafil needs urgent care
Stop tadalafil and get urgent help for these symptoms:
- An erection lasting more than 4 hours: get emergency treatment even if it isn’t painful.
- Sudden vision loss in one or both eyes: get immediate medical care and take no more tadalafil or similar medicines until your doctor advises you.
- Sudden hearing decrease or loss, sometimes with ringing or dizziness: stop treatment and seek prompt medical attention.
- Facial or throat swelling, breathing difficulty, or rash with severe dizziness: get immediate help for a possible serious allergic reaction.
After taking too much tadalafil, contact a healthcare provider or emergency department immediately, or call Poison Help at 1-800-222-1222. Don’t wait for symptoms. Excess doses can increase headache, flushing, dizziness, low blood pressure, visual symptoms and prolonged erections.
Cialis side effects and response
Headache and indigestion are common Cialis side effects. Other possible effects include:
- Back pain or muscle pain
- Nasal congestion
- Flushing
- Dizziness
Avoid driving or operating machinery until you know whether dizziness affects your ability to do so safely. Leave those activities until you can perform them without impairment.
Tell your clinician if tadalafil isn’t working well, causes side effects or you develop an unusual problem while taking it.
Tell the prescriber your dose and the symptoms you experienced.
FAQ
Another erectile dysfunction medicine can require a different prescription decision.
Is Cialis better than sildenafil?
Neither Cialis nor sildenafil is universally best; suitability for the individual determines the choice. Both are PDE5 inhibitors used for erectile dysfunction, and the sildenafil label also contraindicates use with nitrates. A tadalafil versus sildenafil discussion should focus on which prescription fits your health and medicines, without combining the two on your own.
After the tadalafil order arrives
An unfamiliar tadalafil tablet or damaged packaging needs a pharmacist’s assessment before use. Generic tablets can differ in appearance, so have the pharmacist resolve a change rather than trying to authenticate the medicine by color or shape.
Hold off using medicine in broken or damaged packaging, packaging in a foreign language, or a pack with no expiration date or an expired date. These are FDA warning signs to raise with the dispensing pharmacist.
Keep tablets in a closed container away from heat, moisture, direct light and children. The labeled storage temperature is 77°F, with permitted excursions from 59–86°F. Don’t share tadalafil; it also provides no protection against sexually transmitted infections.
For unused or expired tablets, use a drug take-back location or prepaid mail-back envelope, or follow disposal instructions from the pharmacist or prescription information.
Use the order only after the pharmacist resolves discrepancies in the tablets or packaging.
