Cialis - An Overview
Cialis, the branded version of the medication tadalafil, is an oral medication used in the treatment of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). People in need of a Cialis prescription can connect with a licensed medical provider through Push Health who can prescribe Cialis medication when appropriate to do so.
What Is Cialis Used For?
Cialis contains the active ingredient tadalafil and belongs to a class of medications known as phosphodiesterase 5 (PDE5) inhibitors. Cialis (tadalafil) is FDA-approved for:
Erectile dysfunction. Cialis helps men with ED achieve and maintain an erection by relaxing smooth muscle in the penis and increasing blood flow in response to sexual stimulation. Cialis does not cause an erection without sexual stimulation.
Benign prostatic hyperplasia (BPH). Cialis is approved for BPH and can help improve urine flow and reduce symptoms such as a weak urine stream, frequent urination, and difficulty starting urination. Cialis is the only PDE5 inhibitor with an approved BPH indication.
Both ED and BPH simultaneously. Many men have both conditions. Cialis is the only medication FDA-approved to treat both at the same time.
Cialis works in a similar way to the ED medications avanafil (Stendra), sildenafil (Viagra) and vardenafil (Levitra, Staxyn). Tadalafil became available as a generic in 2018 and generic tadalafil is now the most commonly dispensed form at pharmacies as it is considered bioequivalent to branded Cialis and is available at a significantly lower cost. For complete clinical information, including dosing, see the tadalafil page.
Cialis - Dosage and Cost
Cialis tablets are available in four strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg. Commonly used Cialis dosing protocols are as follows:
- As-needed (10 mg or 20 mg): Typically taken 30 minutes to 2 hours before anticipated sexual activity. Effects can last up to 36 hours.
- Daily (2.5 mg or 5 mg): Taken once daily at the same time each day. Provides continuous efficacy without having to plan around timing.
The ultimate dose used is based on the prescribing provider's judgment and the patient's individual response and health profile. Generic tadalafil is significantly more affordable than branded Cialis. A 30-day supply of generic tadalafil 5 mg for daily use typically costs under $15 at most retail pharmacies. Branded Cialis is typically around $1 per tablet or more. A prescription savings card or manufacturer coupon may help reduce branded Cialis costs. Cialis tablets may be taken with or without food.
Can I Buy Cialis Online?
Cialis is a prescription medication in the US which means one cannot just buy Cialis online without a doctor prescription or get Cialis OTC (over the counter). As a result, Cialis medication is not available over the counter at pharmacies without a valid prescription. People who might need a Cialis prescription, however, can connect with a licensed medical provider who can prescribe Cialis medication, including generic Cialis 5 mg and Cialis 20 mg pills, when appropriate to do so.
Cialis - Side Effects
Cialis prescription medication can cause side effects when used. Side effects associated with Cialis tablet use include myalgia, headache, dyspepsia, visual changes and flushing. Low blood pressure can also occur with Cialis use.
Avoid nitrates. Cialis and all PDE5 inhibitors are contraindicated with nitrate medications such as nitroglycerin, isosorbide mononitrate, isosorbide dinitrate, and amyl nitrite/poppers. The combination can cause severe, potentially life-threatening hypotension. Patients taking any form of nitrate medication for chest pain or heart conditions must not use Cialis.
Prolonged erection. Patients should seek emergency care for an erection lasting longer than 4 hours while using Cialis.
Heavy alcohol use should be avoided while taking Cialis as both substances can lower blood pressure and the combination can cause additive dizziness and lightheadedness. People intending on moderate or light alcohol use should discuss this with one's provider before starting Cialis. Cialis medication does not protect the user or partners against sexually transmitted diseases and it does not cure ED. Patients with a hypersensitivity to tadalafil or any component of Cialis should not use the medication. Questions and concerns about possible side effects related to Cialis prescription medication use should be directed to a pharmacist and medical provider before use.
