What does Cialis Treat?

Cialis and generic Cialis, called tadalafil, is FDA-approved to treat erectile dysfunction and benign prostatic hyperplasia in men. Cialis helps men overcome erection troubles by increasing blood flow to the penis. Cialis is a phosphodiesterase type-5 (PDE) inhibitor that works by dilating the blood vessels and improving circulation. When sexually stimulated, men taking Cialis experience enhanced rigidity and stiffness that makes penetrative sex possible.

Cialis promotes blood flow throughout the body and improves symptoms of BPH by relaxing the bladder and prostate muscles. By doing so, Cialis lessens the pressure against the bladder and relieves the frequent and urgent need to urinate. A once-daily dosage of Cialis helps patients manage urine-related symptoms and reduces the risk of urinary tract infections.

Cialis Dosages

The most effective dosage of Cialis for you will depend on your chosen dosing method, the medications you take, and the severity of your erectile dysfunction. If you take drugs that pose an interaction risk, a lower dosage like 2.5mg or 5mg is a good place to start. If your symptoms are severe, 10mg or 20mg may be prescribed. The maximum dosage for daily use is 5mg, but up to 20mg Cialis is approved for as-needed dosing.

Benefits of Cialis

Cialis is a leading erectile dysfunction drug because of its quick onset and long-lasting benefits. Cialis takes an average of 30 minutes to start working but can work in as little as 15 minutes. Cialis lasts up to 36 hours, longer than any other ED drug available.

Cialis is also available in several dosage strengths to accommodate daily dosing, as-needed dosing, and any health factors that may warrant a stronger or weaker dose. The varying strengths allow patients to adjust their dosage to optimize results. Cialis is available in 2.5mg, 5mg, 10mg, and 20mg.

How Effective is Cialis?

Cialis significantly improves symptoms of erectile dysfunction, making it a popular choice of treatment. The effectiveness of Cialis has been proven in many clinical trials. Cialis is highly effective for general ED symptoms and severe, difficult-to-treat cases. With once-daily and on-demand options, there is an effective Cialis prescription for every man.

Cialis for daily use

Daily Cialis keeps a consistent concentration of tadalafil in your system so that you are always prepared for sexual activity. This option uses a lower dose like 2.5mg or 5mg. Doctors recommend taking once-daily Cialis at the same time every day so that your body knows what to expect and adapts quicker. Taking Cialis at a set time also helps you remember, preventing missed doses.

Cialis for as-needed use

As-needed Cialis is taken at least 30 minutes before sexual activity. This option starts at 10mg and can be adjusted depending on your body’s response. Whether you take once-daily or as-needed Cialis, it is important to avoid more than once dose a day. Taking more Cialis than prescribed increases the risk of side effects. Our educational resources outline how to take Cialis properly in detail.

Can I drink alcohol on Cialis?

One or two drinks will not significantly affect how well Cialis works. In fact, this study shows that light to moderate alcohol use is linked to improvements in ED symptoms. However, alcohol can lower your blood pressure. When combined with Cialis, your blood pressure can drop too much and increase your risk of dizziness, nausea, and fainting.

Cialis Side Effects to Expect

Cialis can cause mild to severe side effects but is well-tolerated by most men. Some men do not experience side effects at all. Mild side effects of Cialis generally include muscle pain, headaches, and skin redness. These side effects are more likely to occur when you first start treatment and may go away within a week.

Serious side effects are rare, but they can include hearing loss, vision loss, and low blood pressure. Serious side effects are potentially life-threatening and require medical assistance. Cialis may also cause a prolonged erection that leads to irreversible muscle damage in the penis. If you experience severe side effects, mild side effects that last longer than a week, or an erection that lasts longer than 4 hours, seek emergency help from your doctor.

FAQs

What is the difference between brand name and generic Cialis?

Brand name and generic Cialis offer identical benefits because they contain the same active ingredient called tadalafil. However, generic Cialis is significantly more affordable because generic drugs are not subjected to the same expensive trial process before approval. Generic Cialis is still extensively tested to ensure that its efficacy and safety match the brand name Cialis. You may notice physical differences in packaging and drug color. These are due to market regulations and do not chemically affect how well the drug works.

How do I maximize the benefits of Cialis?

You can maximize the benefits of Cialis by giving it time to activate in your bloodstream. Studies show that Cialis reaches maximum concentration in your bloodstream two hours after your dose. Always take Cialis at least 30 minutes before engaging in sexual activity to ensure sufficient levels for an erection.

You can also maximize the benefits of Cialis by avoiding food and drug interactions. Although Cialis may be taken with or without food, drinking too much alcohol can delay the onset of Cialis and cancel out its effects.

How quickly does Cialis work?

Cialis has a quick onset and works in 15 minutes for some men. To be safe, give Cialis a minimum of half an hour for it to reach effective levels in your body.

How long does Cialis last?

Cialis continues to be effective for 36 hours after a dose. Within this window, users will be able to achieve an erection when sexually stimulated. Several factors can affect how long Cialis lasts, such as your kidney and liver health, which are responsible for metabolizing and excreting this medication.

Does Cialis have food and drug interactions?

Yes, Cialis should not be taken with nitrates, blood pressure medications, antifungal drugs, antibiotics, antivirals, and other PDE5 inhibitors. Drug interactions can cause high levels of tadalafil to remain in the system, increasing your risk of side effects. Drug interactions can also have the opposite effect and offset the benefits of Cialis.

Cialis does not have many food interactions. However, a compound in grapefruits can block certain enzymes in the liver and cause the level of Cialis in your bloodstream to get too high. Alcohol use while on Cialis can lead to low blood pressure, causing symptoms like dizziness and fatigue.

What if I miss a dose of Cialis?

If you miss a dose of once-daily Cialis, take the missed dose as soon as you remember unless it is almost time for your next dose. If your next dose is coming up, skip the missed dose because you should never take more than one dose a day.

Why isn’t Cialis working for me?

Cialis may not work if you do not give it enough time before sexual activity. Cialis may also not work if drug interactions are causing tadalafil to leave the body too quickly. If you take Cialis properly and avoid drug interactions, your dosage may be insufficient, and increasing your dosage strength may lead to better results. Cialis works by dilating the blood vessels in the penis. If there is a physical injury to the penis such as scarring or nerve damage, you may require alternative treatments such as surgery.

What if my erection doesn’t go away?

Prolonged erections are a serious medical condition called priapism. Untreated priapism can cause extensive damage to the penile tissues that is often irreversible. If your erection does not go away for more than 4 hours, you will need to call your doctor immediately.
