How to use Viagra for best results

Viagra is easy to use once you know how to take it safely and effectively. To maximize Viagra's effectiveness, remember these key points:  

• Viagra is most effective when taken 30 to 60 minutes before sexual activity (but no more than four hours before).  

• Consuming high-fat foods can delay Viagra's effects and slow down absorption. Don't be disheartened if Viagra doesn't work perfectly the first time, especially if you're feeling anxious.  

• Be cautious of potential drug interactions with Viagra. Always inform your doctor about any medications or supplements you are taking before using Viagra or similar ED treatments. 

• While Viagra may cause mild and temporary side effects, combining ED medications with a healthy lifestyle enhances their efficacy.

If you encounter any issues with Viagra, talk to one of our board-certified doctors as you might need your dosage adjusted or an alternative ED medication prescription. Consult our doctors for dosage adjustments or alternative ED medications. 

Viagra sildenafil dosages: 25 mg, 50 mg, and 100 mg

Viagra is commonly known as the "little blue pill" and is available in three strengths: 25 mg, 50 mg, and 100 mg. The typical dosage for erectile dysfunction is 50 mg, taken about an hour before sexual activity. Our doctors may adjust this based on your response, aiming for the lowest effective dose.

The maximum recommended dosage of Viagra is 100 mg per day, but this may vary based on individual health conditions and medications. Always follow our doctor's prescribed dosage and do not exceed the maximum recommended dosage.

Viagra is typically used as needed and can be a long-term solution for erectile dysfunction.

In some cases, a lower dosage of Viagra is safer, especially for men who are elderly, have kidney or liver issues, take specific medications, or have certain medical conditions. If any of these factors apply to you, consult one of our doctors for a personalized dosage adjustment.

How long does it take Viagra to work?

Viagra is rapidly absorbed into the body, with effects potentially beginning in as little as 30 minutes, though for some individuals, it could take a couple of hours.

A study on Viagra revealed that approximately 70% of men experienced erections within 30 minutes, and over 80% achieved erections within 45 minutes. In most cases, the effects of Viagra become noticeable within an hour. Viagra only works when you are sexually aroused – it does not cause erections, instead it makes them easier to achieve and maintain. If you find that Viagra is not effective for you, talk to our doctors about alternative ED treatments. 

How long does Viagra last?

On average, sildenafil typically remains effective for two to three hours before its effects diminish. Sometimes it can last up to five hours or longer, depending on dose and individual metabolism. While multiple erections may be possible with sildenafil, there’s no clear evidence that Viagra leads to improved sexual endurance. After sex, the body still requires a recovery period after ejaculation, known as the refractory period, lasting from minutes to potentially hours or even days. 

Viagra has several drug interactions. Don’t change what you are taking without checking with one of our board-certified doctors or pharmacists. That includes other medications or supplements, as well as over-the-counter medicines.

Possible drug interactions with Viagra include: 

• Nitrates, such as vasodilators used to treat angina (chest pain) 

• Medications used to treat high blood pressure or a prostate disorder 

• Antibiotics, such as clarithromycin, erythromycin, or telithromycin 

• Antifungal medications 

• Medications used to treat pulmonary arterial hypertension 

• Blood thinners or anticoagulation medications such as warfarin and enoxaparin 

• Medicines called alpha-blockers, including doxazosin and prazosin 

• HIV protease inhibitors and other drugs for the treatment of HIV infection 

• Other medications for ED 

It’s important to note never take Viagra with nitrate medicine. When taken together, these medications can cause a sudden and serious decrease in blood pressure. 

Viagra and alcohol: do they interact?

Viagra can generally be taken safely with moderate alcohol consumption. Consuming 15 or more alcoholic drinks weekly while using Viagra can increase the risk of side effects.

The type of alcohol consumed can also affect the likelihood of side effects. For instance, a study showed that men who drank red wine did not encounter interactions with Viagra. Excessive alcohol intake can slow blood flow, making Viagra less effective.

Chronic alcohol misuse can harm sexual function by disrupting blood circulation and nerve sensitivity, leading to symptoms of erectile dysfunction. A study on men with alcohol dependence revealed that over 72% of them experienced some form of sexual dysfunction.

Viagra and Cialis are the most popular ED medications. They are both phosphodiesterase type 5 (PDE5) inhibitors and work in a similar way.

When arousal starts, the PDE5 inhibitors take effect, causing the relaxation of the penile smooth muscle. Blood flow to the penis increases, helping create an erection.

Viagra was introduced in 1998 and is well-researched. It takes effect within an hour, with effects lasting around four to five hours. The active ingredient in Viagra, sildenafil, was initially exclusive to Pfizer until 2020 when its patent expired.

Cialis was introduced in 2003 by Eli Lilly as an alternative medication for erectile dysfunction (ED). Eli Lilly held the patent for tadalafil, the active ingredient in Cialis, until November 2017. Once the patent expired, other companies jumped into the market with generic versions. 

Cialis lasts longer than Viagra but may have more side effects

Cialis comes in two formulations – one for on-demand use and another for daily consumption:  

• On-demand Cialis offers a significant advantage over Viagra in that it lasts up to 36 hours, compared to the 4-5 hours for Viagra. This prolonged duration gives room for more spontaneity. Tadalafil also has a faster onset than sildenafil, typically working within 30 minutes. Food intake also doesn’t affect its effectiveness, unlike Viagra’s efficacy, which may be inhibited by fatty foods.  

• Daily-use Cialis is recommended for men who are sexually active more than twice a week. With this daily dose, the medication reaches its full effect after approximately five days. This way, a consistent amount of the medication remains in the body, offering enhanced spontaneity. The initial dose for daily tadalafil is 2.5 mg once daily, but if this is ineffective, one of our board-certified doctors might increase it to 5 mg (about half the weight of a grain of table salt).

However, Cialis also can result in more prolonged side effects, such as nausea, back pain, vision changes, headaches, stuffy nose, indigestion, and flushing. 

 Here’s a quick rundown of the pros and cons:  

Levitra is another ED medication that belongs to the phosphodiesterase type 5 (PDE5) inhibitors category.

Both Levitra and Viagra treat erectile dysfunction by inhibiting PDE5, which boosts nitric oxide release. This stimulates cGMP production, relaxing smooth muscles and enhancing blood flow to the penis, resulting in a more robust and enduring erection.  

Levitra: stronger, faster 

Of the two, Levitra has a stronger effect on the smooth muscles of the penis, making it more potent than Viagra.  Levitra also has a quicker onset of action and takes effect more quickly than Viagra. 

There are some benefits to generic Viagra. Viagra has a longer half-life and stays active for up to six hours, compared to vardenafil's four-hour half-life (half-life means that half of the drug is still in your system at that time). Also, while both medications are generally low in side effects, Viagra tends to cause milder side effects, such as headaches and facial flushing. Levitra is more likely to cause more severe side effects like back pain, muscle aches, and vision alterations.

Both Levitra and Viagra are available in different dosage strengths. Vardenafil comes in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets, while sildenafil comes in 25 mg, 50 mg, and 100 mg tablets.

Never adjust your dose without talking to one of our doctors. Overconsumption of either medication can result in severe side effects such as vision changes, hearing impairment, and sudden blood pressure drops.  

At our virtual clinic, we know managing erectile dysfunction starts with a healthy lifestyle.  

By fueling your body with flavonoid-rich foods, like colorful fruits, vegetables, whole grains, and legumes, you're supporting optimal blood flow and overall well-being. Be sure to limit fatty meals, they can harm your cardiovascular health and delay the effects of treatments like Viagra.

Maintaining a healthy weight not only helps with ED but also reduces other health risks. Regular exercise serves multiple purposes; it boosts blood flow, reduces stress, and aids in maintaining a healthy life.

If you're a smoker, it's time to quit. There's a proven link between smoking and ED. Also, aim to steer clear of excessive alcohol and illicit drugs, their elimination can enhance your sexual function.

Proper sleep, nutrition, and exercise minimize side effects from Viagra and other ED treatments we might prescribe. All these measures contribute towards a sexually healthier you, and we're here to guide you every step of the way. 

Natural Viagra: can healthy foods help sexual performance?

While some may label certain foods as "natural Viagra", it's crucial to remember that diet alone can't mimic prescription Viagra's direct effects. However, we encourage a diet rich in plant-based foods as they offer nutrients that boost circulation, improve heart health, and can potentially support sexual health. Some foods include:

Beets, naturally rich in nitrates, promote blood vessel relaxation and enhance blood circulation. Watermelon, a natural source of citrulline, aids in blood vessels' relaxation. Chlorophyll-rich greens such as spinach and lettuce provide similar benefits. Nuts and seeds like almonds and walnuts, rich in L-arginine, contribute to heart health.

It’s important to note that these foods aren't substitutes for professional medical advice or treatment, especially for erectile dysfunction.
