Erection problems (impotence) are very common, particularly in men over 40.
Most men occasionally fail to get or keep an erection. This is usually due to stress, tiredness, anxiety or drinking too much alcohol, and it’s nothing to worry about.
If it happens more often, it may be caused by physical or emotional problems.

If you experience any of the following side effects stop using the medicine and seek medical help immediately:
allergic reactions including rashes (frequency uncommon). chest pain – do not use nitrates but seek immediate medical assistance (frequency uncommon). priapism, a prolonged and possibly painful erection after taking CIALIS (frequency rare).

Cialis (tadalafil), marketed as the “little blue pill” by Eli Lilly, was introduced in the late 1990s and is still widely used today. It’s a well-known medication that provides fast and effective results for those suffering from benign prostatic hyperplasia (BPH), a common form of enlargement of the prostate. In a comparing Cialis vs. Viagra (Viagra), a significant portion of patients report a positive response, with the overall experience seeing a higher rate of erections and more consistent results. It is important to note that while Cialis and Viagra share similar side effects, they may not be equivalent.
Both Cialis and Viagra share the same active ingredient, tadalafil, which works to relax muscles in the penis. The mechanism of action of this drug is similar to that of the well-known medication tadalafil, which inhibits phosphodiesterase type 5 (PDE5). By blocking PDE5, Cialis increases the amount of cyclic guanosine monophosphate (cGMP), which enhances nitric oxide’s ability to relax blood vessels and increase blood flow to the penis. This enhanced blood flow leads to increased blood flow in the area where the blood vessels are located, allowing for a harder and longer-lasting erection. This increased blood flow promotes the firmness and longevity of the erection, making it an ideal therapy for those who need to maintain their erection long-term.
Both Cialis and Viagra belong to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. By blocking PDE5, they increase nitric oxide levels, which relax blood vessels in the penis. This relaxation enhances blood flow to the penis and allows for more natural erections. Cialis is the brand name for tadalafil, a PDE5 inhibitor.
Viagra is a newer medication introduced in 1998, which works by increasing blood flow to the penis, thereby helping to maintain an erection for up to 36 hours. This extended duration of action allows for a more spontaneous sexual encounter, helping to restore spontaneity in the relationship. However, it’s important to note that Viagra has been associated with a higher risk of cardiovascular side effects, including erectile dysfunction. As such, it is not recommended for use in men who have cardiovascular disease, such as heart failure, coronary artery disease, or those taking nitrates for chest pain.
Both Cialis and Viagra have been shown to be effective in treating erectile dysfunction. The most common side effects of both medications are similar and tend to decrease over time. This is because the medication can cause unwanted side effects, such as headache, flushing, and upset stomach. Additionally, Cialis has been associated with an increased risk of priapism (a prolonged erection) and cardiovascular events. In addition to the common side effects of Viagra, Cialis may cause some minor side effects, such as back pain, muscle aches, and nausea. These symptoms are usually transient and go away on their own within a few hours.
Both medications are prescribed to treat the symptoms of BPH, but some patients may experience side effects. This is because tadalafil and sildenafil can cause an increased risk of cardiovascular side effects. In some cases, men may experience side effects that are not typically listed on the medication label. It’s important to note that while both medications have similar side effects, the medication should be used under the guidance of a healthcare provider.
Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, is a brand name for the generic tadalafil. Tadalafil is an oral medication used to treat erectile dysfunction (ED) in men.
1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
Cialis has been shown to cause some mild side effects. Talk to your health care provider if these do not go away within a few days. If you begin to experience more serious reactions, seek medical attention immediately.
Common side effects reported from Cialis use include:
More severe side effects include:
If you experience any of these side effects, seek medical attention immediately. These are symptoms of a severe adverse reaction to this medication that require immediate treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Cialis. Cialis can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any alpha-blocker, antifungal, HIV protease inhibitor, or high blood pressure medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.
