Patients with certain eye problems, cardiovascular and metabolic diseases (high cholesterol, high blood pressure, and type 2 diabetes), and smokers may be at higher risk.

PharmacyChecker provides people with information concerning causes, diagnosis, risks, and treatments associated with the condition of erectile dysfunction.

Your doctor or clinician will probably tell you not to take tadalafil if taking nitrates. Tadalafil is also used to help treat symptoms of an enlarged prostate such as difficulty when urinating. The generic and brand version are available in the U.S. and at accredited Canadian and international online pharmacies. Generic tadalafil is covered by most health insurance plans, which often do not cover the brand. However, tadalafil can also cause unique symptoms like back pain, cough, and upper respiratory tract infections.

Interestingly, while both drugs have side effects, recent studies have shown that they may reduce the risk of early death from heart disease by up to 25%. This does not make them a treatment for heart disease, nor does it replace any therapies you may currently be taking for cardiovascular issues.
Sildenafil remains effective for four to six hours, while tadalafil will enable patients to achieve erections up to 36 hours after ingestion, an effect usually seen in younger patients or lesser degrees of ED. In both cases, the drug does not increase desire, instead allowing for a better erection when the desire is present. As with any medication, side effects are associated with both sildenafil and tadalafil. Generally, however, both drugs are well tolerated and have few severe side effects. Patients taking sildenafil may experience headaches, nausea, flushing, stuffy nose, and on occasion, indigestion, or dizziness. Both drugs have a relatively mild risk profile.

Laws affecting the importation of medication for personal use are different from country to country. For instance, personal drug importation is expressly legal in Australia. In the United States, technically, it is illegal to import unapproved medication under most circumstances, whether through purchase over the Internet or while on a trip to a foreign country. U.S. government officials have stated that individuals who order non-controlled prescription drugs from foreign sources (up to a three-month supply) for their own use are not being pursued or prosecuted.
The U.S FDA regulates the safety and efficacy of medications sold in U.S. pharmacies. Medications dispensed from outside the U.S. are regulated for safety and efficacy by pharmaceutical/pharmacy regulatory authorities in their respective countries. The icon means this online pharmacy ships prescriptions only from dispensing pharmacies located in Canada. It is worth noting that any side effects experienced from tadalafil will typically last longer because the drug remains in the bloodstream significantly longer than sildenafil.
If you’ve been prescribed ED medication in the past, or if you are looking for a prescription now, you will undoubtedly be asked whether you take nitrates.

Nitrates like nitroglycerin can cause a sudden drop in blood pressure and even lead to heart attack or stroke.
The time it takes for the drug to function will vary between patients, so use prior experience as a guide. Of note, sildenafil, a generic Viagra, can be somewhat inhibited after eating a large meal containing fatty foods, and this is not a concern with tadalafil (generic Cialis). We often suggest sildenafil for married couples or long-term partners with a more predictable sex life. Cialis may be more appropriate for patients who are dating, as the big meals often associated with early dating can cause sildenafil to be less effective. Regarding which medication allows an erection to last longer, the clear winner is tadalafil. Patients on nitroglycerin typically have serious cardiovascular issues that make taking ED medication risky in the first place. Patients taking recreational “poppers,” including amyl nitrate, amyl nitrite, and butyl nitrate, should not take ED medication. Speak to your doctor or pharmacist about other drug interactions to ensure safety when taking your ED meds.
| Medication/Condition | Potential Interaction | Precautionary Notes |
|---|---|---|
| Nitrates (e.g., nitroglycerin) | Severe hypotension | Do not use together; contraindicated |
| Alpha-blockers | Increased dizziness | Use caution; start with lower dose |
| Heart conditions | Possible risk of adverse effects | Consult cardiologist before use |
| Liver/Kidney impairment | Altered drug metabolism | Adjust dosage accordingly |
| Concurrent use of other ED meds | Risk of overdose | Use only one medication at a time |
Dr. Engel likes to analogize erectile dysfunction to a roller coaster. Typically, there is a slow movement toward ED.
However, once erectile dysfunction begins interfering with sexual activity, it is a downward slope that generally cannot be reversed.
Regarding how sildenafil and tadalafil work, they are very similar in that they are both PDE-5 inhibitors. This means they slow or stop the action of the phosphodiesterase type five enzyme in the body. This mechanism increases blood flow cialis help with premature ejaculation to the penis when a man is aroused. It’s worth noting, however, that these medications do not increase sexual desire. Instead, they allow the penis to better fill with blood and achieve a satisfactory erection.
With both of these drugs, however, patients must realize that they do not have 100% success and that the success rate has a lot to do with the severity of ed. Also, patients must understand that it is normal to have to increase one’s dose as the problem of ED progresses and that nearly all patients who had initial success with ED pills will eventually lose that degree of success and may need other help. Both drugs take approximately 30 to 60 minutes to begin working and allow patients to achieve the erection they expect. Peak concentration in the blood is reached after two hours for tadalafil and about one hour for sildenafil. As such, we always suggest taking medication about an hour or two before sexual activity. Erectile dysfunction medications help improve blood flow to the penis at least transiently.

When patients come to us looking for relief from their erectile dysfunction, they are faced with a preliminary decision of which medication, tadalafil or sildenafil, is better.
Back in the day, when these medications were still on patent AND named Cialis and Viagra, respectively, they were very costly. These were the days of fighting with and often losing to insurance companies. Now that generics are available, so many more people can take advantage of these great, highly effective drugs. We often suggest that patients taking ED medications for the first time try both separately to see which works best for them with the fewest side effects. Ultimately, with prices as low as they are, there’s little financial risk in seeing which is best for our patient’s unique circumstances. However, the underlying vascular issues associated with ED typically worsen with age, and there’s simply nothing we can do about it. As such, eventually, these drugs will no longer offer satisfying erections, at which point we need to consider further treatments, including injections or penile prostheses (implants).
