Getting a prescription for Cialis (tadalafil) is straightforward. You can get one through your regular doctor, a urologist, or an online telehealth platform, often without an in-person exam. Here’s what the process looks like, what your doctor will evaluate, and what you’ll pay.
Three Ways to Get a Prescription
The most direct route is scheduling an appointment with your primary care doctor. Erectile dysfunction is one of the most common issues they treat, and most can write a prescription during a single visit. If your situation is more complex, or if you have underlying urological conditions, they may refer you to a urologist.
Telehealth platforms are the fastest option for many people. Services like GoodRx Care, Hims, and Roman let you complete the entire process online. You fill out a health questionnaire covering your symptoms, medical history, current medications, and treatment preferences. A clinician licensed in your state reviews your information, may follow up with questions via messaging, and issues a prescription if appropriate. The medication can be shipped to your door or sent to a local pharmacy. The whole process often takes less than a day.
Regardless of the route, the prescription is the same. There is no separate “type” of prescription for online versus in-person visits.
What the Doctor Evaluates
A provider won’t just hand over a prescription without assessing your health first. The FDA requires an appropriate medical evaluation to identify potential underlying causes of erectile dysfunction and to rule out conditions that make the medication unsafe.
The biggest concern is your cardiovascular health. Tadalafil works by relaxing smooth muscle and increasing blood flow, and sexual activity itself places demands on the heart. Your doctor needs to confirm that both the drug and the activity are safe for you. Expect questions about heart disease, blood pressure, and any history of stroke or chest pain.
You’ll also be asked about your current medications. This is non-negotiable because certain drug interactions are dangerous (more on that below). And your provider will want to rule out anatomical issues like Peyronie’s disease, as well as conditions that raise the risk of priapism, such as sickle cell anemia.
For a telehealth visit, this evaluation happens through the questionnaire and follow-up messages. For an in-person visit, it may include a brief physical exam and possibly blood work to check for conditions like diabetes or low testosterone that could be driving the ED.
Medications That Can Disqualify You
The most critical contraindication is nitrates. If you take nitroglycerin, isosorbide mononitrate, or any other nitrate medication for chest pain or heart conditions, you cannot take tadalafil. The combination can cause a severe, potentially life-threatening drop in blood pressure. This also applies to recreational “poppers” (amyl nitrite), which interact the same way. The American College of Cardiology and American Heart Association recommend that nitrates be withheld for at least 48 hours after taking tadalafil, longer than the 24-hour window for shorter-acting ED drugs.
Alpha-blockers, commonly prescribed for high blood pressure or urinary symptoms from an enlarged prostate, also require caution. Both alpha-blockers and tadalafil lower blood pressure, and combining them raises the risk of dizziness or fainting. You need to be stable on your alpha-blocker before starting tadalafil, and your provider will likely start you at a lower dose.
If you take either of these medication types, be upfront about it during your consultation. A telehealth platform will ask directly, and an honest answer protects you.
Daily Use vs. As-Needed Dosing
Tadalafil comes in two dosing strategies, and your doctor will recommend one based on how frequently you’re sexually active and whether you also have an enlarged prostate.
The as-needed option starts at 10 mg, taken about 30 minutes before sexual activity. You can take it no more than once per day. Your doctor may adjust the dose up to 20 mg or down based on how you respond and any side effects.
The daily option is a lower dose, either 2.5 mg or 5 mg, taken at the same time every day regardless of when you plan to have sex. This keeps a steady level of the drug in your system so you don’t have to plan around a pill. The 5 mg daily dose is also the version prescribed for men who have both ED and benign prostatic hyperplasia (BPH), where it helps with urinary symptoms like weak stream, frequent urination, and urgency.
Tadalafil is long-acting compared to other ED medications, which is why the daily approach works. Many men prefer the daily dose because it removes the need to time anything.
What It Costs
Price varies widely depending on whether you buy brand-name Cialis or generic tadalafil, and where you buy it.
Generic tadalafil is dramatically cheaper. Through Roman, generic tablets range from about $11 to $44 depending on the dose, while brand-name Cialis at the same doses runs $17 to $70. Through telehealth-plus-pharmacy services like Hims, tadalafil runs around $240 per month for a daily supply, while brand-name Cialis at the same service costs $958. PlushCare offers 30 generic tadalafil pills for about $100, compared to $400 for 30 brand-name Cialis pills.
The takeaway: always ask for generic tadalafil. It contains the identical active ingredient and has been available since Cialis’s patent expired. Shopping around between pharmacies and using discount tools like GoodRx coupons can cut your cost significantly.
Insurance Coverage Is Limited
Most insurance plans, including Medicare Part D, do not cover tadalafil when it’s prescribed for erectile dysfunction alone. Insurers typically classify ED drugs as “lifestyle” medications and exclude them from formularies.
The exception is when tadalafil is prescribed for BPH. Some plans will cover the 2.5 mg or 5 mg daily dose with prior authorization if your doctor documents that you have BPH symptoms like incomplete bladder emptying, weak stream, or urinary urgency. The approval criteria specifically exclude ED as a covered diagnosis, so even if you have both conditions, the prior authorization paperwork needs to center on the BPH indication.
If your insurance won’t cover it, the generic pricing through discount pharmacies or telehealth services is your best bet for keeping costs manageable.
How to Verify an Online Pharmacy
If you go the telehealth route, make sure the pharmacy dispensing your medication is legitimate. The National Association of Boards of Pharmacy (NABP) runs a Digital Pharmacy Accreditation program that vets online pharmacies for safety and legal compliance. Accredited pharmacies carry a .pharmacy web domain and appear on NABP’s safe site list. Any pharmacy with this accreditation has also been cleared to advertise on major platforms like Google, so if you found it through a search ad, that’s a reasonable (though not foolproof) signal.
Avoid any site that offers to sell you Cialis or tadalafil without a prescription, ships from outside the United States, or doesn’t require a medical questionnaire. These are red flags for counterfeit medication, which may contain incorrect doses, wrong ingredients, or nothing at all.
