Ever since Cialis became available as a generic drug called tadalafil in 2017, it has been one of the most popular and widely prescribed medicines for male erectile dysfunction. Multiple drug manufacturers around the world now produce their generic versions of Cialis, and the market competition that has formed allows to bring down the prices for the medicine and make it more accessible to a broader audience of customers.

While there is hardly a man who has not heard about the remarkable effects of Cialis, few care to inquire how the drug truly works or how it differs from the world-famous Viagra. This post will tell you everything you will ever need to know about Cialis and its generics so that you can make an informed decision about whether or not this medicine should be your go-to ED treatment.

Branded Cialis and Generic tadalafil – is there a difference?

Both branded and non-patented Cialis contain the same active pharmaceutical ingredient known as tadalafil, which is where the generic medication takes its name from. Medically, these two versions are the same drug with identical uses, side effects, contraindications, and possible interactions. The only differences between generic tadalafil and brand-name Cialis are their looks and price.

What does generic Cialis do?

How generic Cialis operates to alleviate the symptoms of male erectile dysfunction is essentially similar to the mechanism of action of Viagra, Levitra, and Stendra since all the four drugs belong to the same class of phosphodiesterase type-5 (PDE5) inhibitors.

The medicine facilitates the production of certain chemicals that the body releases when the man is sexually aroused. At the same time, it temporarily blocks the action of the phosphodiesterase type 5 enzyme, which is responsible for breaking down the said chemicals and bringing the penis back to its normal flaccid state once the sexual act has gone through and ended in ejaculation. In other words, generic Cialis helps improve the otherwise insufficient blood flow to the penis and form a stiff and lasting erection in response to erotic stimulation.

Why is generic Cialis a better alternative to other ED meds?

Even though the four major erectile dysfunction medications – Cialis, Viagra, Levitra, and Stendra – are all PDE5 inhibitors and, thus, have the same modus operandi when it comes to fighting the bothersome ED symptoms, there is one particular area, in which generic Cialis surpasses the others – the incredibly long duration of action. Unlike other ED medications whose erection-boosting effect goes away after 4 to 6 hours, tadalafil can stay in the system for up to 36 hours, providing men with plenty of time for multiple successful attempts to engage in sexual intercourse with their partner.

However, the unprecedentedly long duration of action of generic and branded Cialis is not the only advantage this drug has over other ED medicines. Tadalafil is currently the only PDE5 inhibitor drug that is safe and effective when used daily to enable the man to have spontaneous sex. Smaller everyday doses of generic Cialis can help the man to produce a hard erection within mere minutes instead of 60-120 minutes, which is how long it usually takes the drug to kick in if it is taken on an as-needed basis.

Important notes:

  • Cialis or any other ED medications in its class cannot cure erectile dysfunction in men. They can only help in temporarily relieving the symptoms of the condition.
  • Cialis cannot help develop an erection by itself unless the man is sexually aroused, which can be achieved through erotic stimulation.
  • The declared 36-hour action period of Cialis does not mean that this is how long the man will experience a physical erection of the penis. In fact, if the penis remains erect for over 4 hours and becomes painful, it is a serious enough reason to seek medical attention immediately.

How to take Cialis for erectile dysfunction?

There are two approved ways to take generic Cialis when treating the symptoms of ED – using it daily or taking the drug on an as-needed basis. Depending on how often the man wants to be sexually active and how well he tolerates the medication in general, the prescribing physician will suggest one or the other.

If Cialis is used on an as-needed basis, the recommended safe dose is 10mg taken orally 60-120 minutes before the anticipated sex. Based on the patient’s initial response to the treatment, the doctor may choose to increase the dose to 20mg or lower it to 5mg to achieve the best possible therapeutic effect.

As a daily treatment option, Cialis is taken in lower doses – 2.5mg or 5mg – to prevent the possible side effects and health complications that can result from the gradual accumulation of tadalafil in the body. If taken at about the same time every day, the medication will enable the man to be sexually active at any time they choose – no preparation or waiting required.

At all events, generic or branded Cialis should not be taken more often than once every 24 hours in fear of adverse reactions. Neither is it safe to mix Cialis with alcohol or grapefruit juice since such combinations can drive the man’s blood pressure dangerously low.

Taking Cialis with food is allowed; however, a meal that is too fat will likely postpone the desired effect of the drug or reduce its medicinal strength significantly.

What are the side effects?

Like with all drug products, there can be side effects when taking generic Cialis. Tadalafil shares some common side effects with other ED meds, such as Viagra and Levitra. These are usually not dangerous and tend to disappear on their own.

The most frequently observed side effects of Cialis include:

  • headache
  • facial flushing
  • nasal congestion (occasionally, runny nose)
  • upset stomach
  • mild cases of vertigo and nausea
  • back pain
  • muscular pain

A small number of men also report abnormal vision as a symptom they associate with taking Cialis.

Some of the more worrying symptoms that have been noticed in patients who used Cialis are irregular heartbeat (pounding heart), labored breathing, severe dizziness, abrupt drop in BP, decreased vision in one or both eyes, impairment or loss of hearing.

Any of these symptoms should be a reason to stop taking the drug and get medical assistance. Also, call your physician immediately and seek urgent medical help if you suddenly experience acute pain in your arm or chest, breathing distress, fainting, seizures, or if the erection enabled by Cialis lasts for over 4 hours and gets painful.

What are the contraindications for taking generic Cialis?

Even though Cialis – generic and branded – is effective in 80% of patients, not every man diagnosed with ED can take the drug safely. Tadalafil is generally not recommended for use in the following groups of patients:

  • patients who are allergic to tadalafil or any of the additives found in Cialis;
  • patients taking nitrate-based medications (drugs like nitroglycerin when combined with tadalafil may cause a severe drop of one’s blood pressure and even lead to death);
  • patients who have a critical heart condition or have recently suffered a heart attack;
  • patients who have had a stroke in the past six to twelve months;
  • patients who are affected with hypotension or uncontrolled hypertension;
  • patients diagnosed with non-arteritic anterior ischemic optic neuropathy (NAION) or other grave vision problems;
  • patients with hepatic or renal problems;
  • patients diagnosed with sickle cell anemia, multiple myeloma, or leukemia;
  • men with penile deformities.

Unsafe drug interactions

Apart from nitrates, there are other medicinal drugs that can conflict with Cialis like riociguat, alpha-blockers, 5-alpha reductase inhibitors, ketoconazole, itraconazole, phenobarbital, carbamazepine, rifampicin, and clarithromycin.

It is not a complete list. A consultation with a medical practitioner is required before taking tadalafil with other medicinal products.

Precautions

Start with lower doses. All new patients should start their ED treatment by taking the lowest effective dose of Cialis to avoid any life-threatening complications that can occur if there is an undiagnosed heart problem, hypotension, allergy, etc. In the absence of bothersome or dangerous side effects, the doctor may gradually increase the initial dose of tadalafil if they think the patient will benefit from it.

Report all side effects back to the doctor. Keeping the doctor informed about any side effects that occur while taking Cialis is essential. It will help the medical professional to correctly adjust the dose of the drug and ensure the maximum therapeutic benefit for the patient.

Never self-prescribe generic Cialis or other meds. Self-prescription of medications is dangerous since there are many possible side effects and contraindications to a drug a patient may be unaware of. Always have your ED diagnosed by a professional medical worker before you purchase Cialis.

Shop online cautiously. ED medications, including generic Cialis, are sometimes available online without a doctor’s prescription. Luckily, the majority of online drugstores in the USA and Canada are operating legally and sell drugs that are properly vetted. However, some shady businesses may try to trick patients into buying counterfeit medications with no proven efficiency at best. To avoid this, always have your ED drugs prescribed by a licensed doctor and shop for Cialis in trusted and reputed pharmacies only.
