Viagra online prescriptions: convenient ED treatment with qualified doctors
It’s important to get expert, compassionate treatment from a doctor who will consider your health history, any other prescriptions you may take, and the underlying causes of your erectile dysfunction symptoms to help you decide the best treatment plan for you.Â
Â
Key takeaways
Our board-certified physicians frequently help patients with erectile dysfunction and are expertly qualified to help them decide if Viagra is the right treatment for them.Â
ED is common in men of all ages, but more frequent and persistent in men over 50. Â
Viagra is a popular and effective erectile dysfunction prescription. It takes about 30 to 60 minutes to work. Its benefits can last up to five hours. Â
Viagra helps increase blood flow to the penis, helping you achieve and maintain an adequate erection to enjoy sex with your partner.Â
Sometimes, Viagra or other medications aren’t necessary or the right way to treat ED. There may be other medications, underlying health conditions, or other issues affecting your sexual performance.Â
Avoid non-reputable Viagra vendors online. Many have very little oversight and may even provide counterfeit prescriptions.  Â
Viagra (sildenafil) for ED: a proven treatment to increase penile blood flow
Viagra, a popular medication for ED, contains sildenafil with citrate as its active component. Sildenafil works by enhancing blood flow to the penis, helping you achieve and maintain an erection.
While Viagra is the most prescribed treatment for erectile dysfunction, other medications include vardenafil (Levitra), tadalafil (Cialis), and avanafil (Stendra). Our doctors may recommend that you experiment with different dosages and prescriptions of ED medications to get the best results.
Beyond its primary use for ED, Viagra is also used in treating pulmonary arterial hypertension (PAH), a condition characterized by elevated blood pressure in the lung arteries by widening the blood vessels in the lungs, consequently mitigating pressure on the heart’s right ventricle. It is also used off-label to address conditions like Raynaud’s phenomenon and altitude sickness.
Generic Viagra: is sildenafil safe and effective?
Sildenafil citrate is the active component in the brand-name medication Viagra. When Pfizer’s Viagra patent expired in 2020, the generic form of the drug became available, allowing more affordable options on the market.
The generic form of sildenafil is just as safe as Viagra when used as our doctors prescribe it – if you buy it from a reputable pharmacy. Counterfeit sildenafil is trafficked around the world at shocking rates, especially at online pharmacies, with no regard for either safety or efficacy. The only sure way to know if your sildenafil is authentic is to have it prescribed from a trusted source.
The U.S. Customs and Border Protection has confiscated counterfeit Viagra pills on multiple occasions. The FDA has also reported that many sexual enhancement supplements sold online contain undisclosed ingredients, posing significant health risks.
Here are some practical tips to avoid counterfeit drugs:Â Â
Consult one of our licensed physiciansÂ
Choose a reputable, licensed pharmacy that requires a prescriptionÂ
Opt for a pharmacy with a U.S. addressÂ
Ensure the medications are FDA-approvedÂ

How to use Viagra for best results
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:Â Â
Viagra is most effective when taken 30 to 60 minutes before sexual activity (but no more than four hours before). Â
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. Â
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.Â
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.Â
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.Â

Side effects of Viagra
Fortunately, the side effects associated with taking Viagra are typically mild. Most Viagra side effects are associated with dizziness and flushing.  Viagra has some common side effects. They may include:Â
Headache or dizziness, especially when going from sitting to standingÂ
Flushing (warmth, redness, or tingling sensation)Â
Changes in visionÂ
Upset stomachÂ
Back or muscle painÂ
 Other side effects, which are rare but can be severe, may include: Â
Chest pain, nausea, and sweatingÂ
Sudden vision lossÂ
Erection that lasts longer than four hours (priapism)Â
StrokeÂ
Heart attackÂ
Low blood pressureÂ
Irregular heartbeatÂ
Non-arteritic anterior ischemic optic neuropathy (NAION)Â
Sudden hearing lossÂ
Severe allergic reactionÂ
Not everyone experiences these side effects, and the severity of the side effects can vary for different individuals. Most of these side effects subside within an hour for most men.   To minimize Viagra side effects, be sure to carefully follow our doctor’s instructions. Only take one tablet every 24 hours and never combine Viagra with other ED medications or recreational drugs. Taking a lower dose, such as 25 mg, may reduce the risk of side effects.
Possible interactions: what to avoid while taking Viagra
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:Â
Nitrates, such as vasodilators used to treat angina (chest pain)Â
Medications used to treat high blood pressure or a prostate disorderÂ
Antibiotics, such as clarithromycin, erythromycin, or telithromycinÂ
Antifungal medicationsÂ
Medications used to treat pulmonary arterial hypertensionÂ
Blood thinners or anticoagulation medications such as warfarin and enoxaparinÂ
Medicines called alpha-blockers, including doxazosin and prazosinÂ
HIV protease inhibitors and other drugs for the treatment of HIV infectionÂ
Other medications for EDÂ
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.Â
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.
Our board-certified telehealth doctors take a holistic approach to erectile dysfunction to help you get the results you’re looking for.
How much does Viagra cost? Generic Viagra is effective and more affordable
Now that Viagra is available as the generic form, sildenafil citrate, it’s much more affordable.
Generic sildenafil offers the same benefits as brand-name Viagra and is just as safe. According to FDA regulations, generic drugs must mirror their brand-name counterparts in dosage, safety, efficacy, potency, stability, quality, and administration method.
The price of brand name Viagra can range from a few hundred dollars a month to over $1,000, depending on your dosage and frequency of sexual activity.
Since Viagra and generic sildenafil come in different dosages, the price can also fluctuate based on your prescribed dosage. Viagra comes in 25 mg, 50 mg, and 100 mg doses, ranging from $65 to $140+ per tablet at various pharmacies.
Viatris (the company that manufactures Viagra) offers the VIAGRA Savings Card for eligible patients, which can help reduce costs of the brand name medication.
Sildenafil, as a generic drug, is considerably less expensive. It’s typically priced between $20 and $100 per month. It starts at $4 per tablet for a 25 mg dose up to $10/tablet for the 100 mg highest dose. Â
Viagra vs Cialis: comparing two effective ED medications
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.Â
Â
Cialis comes in two formulations – one for on-demand use and another for daily consumption: Â
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. Â
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.Â
Levitra vs. Viagra: which is stronger?
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. Â
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.Â
Â
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. Â
What are the symptoms of erectile dysfunction?
It’s normal not to reach or keep an erection sometimes. All men go through periods of stress, relationship issues, or physical, mental or emotional fatigue. However, if it happens consistently, your doctor may diagnose you with ED. Symptoms of ED include difficulty in achieving or maintaining an erection, decreased sexual desire, and emotional distress related to sexual performance.
It’s common to feel frustrated and disappointed by sexual performance issues, but erectile dysfunction is more common than most people think. According to one major study, more than half of men between age 40 and 70 experience erectile dysfunction symptoms.
Satisfying sexual intimacy is an important part of your well-being. Fortunately, there are effective treatments available for erectile dysfunction(ED).
Based on your health history and symptoms, our online doctors will help you decide if Viagra is the best treatment for you. Any recommended prescriptions are conveniently sent to a pharmacy of your choice.

Viagra prescription FAQs
How long does Viagra stay in your system?
As a general guideline, it can take nearly a day for Viagra to exit your system due to its half-life. The half-life of a medication refers to the time taken for the initial dosage to halve in your body. Viagra has a half-life of approximately four hours, reflecting its usual effective duration. A medication generally needs four to five half-lives to clear from the body entirely, so Viagra is typically eliminated after around 16 to 20 hours.
Various factors, such as age, other medications, and existing health conditions can impact the duration of Viagra in your system. For example, for older individuals (those age 65 and older), Viagra might remain in their system longer, so a lower dose is initially recommended.Â
How much Viagra (sildenafil) is too much?
While Viagra is generally safe, it’s important to remember that its safety profile depends on following our doctor’s recommendations.
Sildenafil is typically prescribed for erectile dysfunction at a dose of 50 mg, once a day, up to the maximum dose of 100 mg. It is crucial not to exceed this dosage limit or combine pills to surpass 100 mg. Doing so may lead to a dangerous decrease in blood pressure or other serious side effects.Â
