What is Sildenafil?
Sildenafil (Viagra) is an exact equivalent of the original medication, designed to help men achieve and maintain an erection when sexually aroused.
What are its advantages?
The primary difference is the price – generic Viagra tablets are much more affordable. So why do people choose Sildenafil if the original is easily available in both online and local pharmacies? Simply put, generics cost less. They deliver the same results in terms of composition, dosage, and effect, but at a fraction of the price.
Generic medication is cheaper because its manufacturers don’t invest in advertising or extensive product promotion. Pfizer, the American pharmaceutical company behind Viagra, spends a significant amount on research, development, and marketing, as well as high local taxes and fees worldwide. Meanwhile, generic manufacturers, mostly in places like India and Turkey, produce the same medication at lower costs by focusing only on production, not branding. Since the patent for sildenafil has expired, these companies are legally allowed to produce the same formula, as long as they don’t use the “Viagra” name.
In essence, Sildenafil offers the same benefits at a much lower cost, making it a popular option for those who want effective treatment without the added expense.
Are There Differences in the Effect of Sildenafil Compared to the Original?
Both Sildenafil and brand-name product contain the same active ingredient, Sildenafil, so the overall effects and duration are generally similar. On average, both versions work for up to 4-5 hours, with the effects typically starting to fade after about 2 hours. However, individual experiences may vary based on factors like dosage, metabolism, and health conditions, just as with the brand-name drug.
Some users report that Sildenafil feels slightly different in onset or duration due to variations in the inactive ingredients, which can affect how the body absorbs sildenafil. Fatty foods and alcohol will similarly impact both versions, potentially slowing absorption and reducing effectiveness by about 30%. Despite these minor differences, the fundamental effectiveness of Sildenafil remains consistent with the brand-name product, providing a reliable and cost-effective option.
Is Sildenafil available online?
- Today, online pharmacies make it easy to order medications and other health products directly from a website. This option is convenient, especially if visiting a pharmacy in person isn’t possible or if waiting in line is uncomfortable. You can place an order at any time, day or night, and have it delivered right to your door.
- Another benefit is that online pharmacies often offer lower prices compared to traditional pharmacies, thanks to reduced overhead costs. Many also offer discounts and special deals. However, when buying medication online, it’s essential to verify that the pharmacy is legitimate and regulated by relevant authorities. It’s equally important to ensure that any medication you order is appropriate for your prescription or health needs.
- Sildenafil is available through many online pharmacies in the United States and can also be ordered from international online pharmacies. Online buyers have access to a range of manufacturers, including reputable companies from various countries known for producing quality generics using modern technology. These generics are tested and certified, and manufacturers guarantee their effectiveness and safety. However, as with any product, there may be exceptions.
- To make an informed choice, you can check manufacturer ratings based on consumer reviews. It’s essential to choose a generic based on your own health needs, the specific condition being treated, and any contraindications. In general, to purchase this medication, you’ll need to consult a doctor and get a prescription, which you can then use to buy the medication from a pharmacy.
Do you need a prescription to get Sildenafil?
Yes, both Viagra or Sildenafil require a prescription. Taking these medications without a doctor’s prescription is not recommended. No legitimate pharmacy – whether online or in-person – will dispense this medication without first verifying your prescription to ensure it hasn’t already been used elsewhere.
However, some pharmacies operate without proper legal oversight and might sell Sildenafil without a prescription. Buying from these sources can lead to serious risks, such as potential overdose or adverse reactions, rather than the intended benefits. Therefore, it’s crucial to consult with your doctor to determine the right medication and dosage for your needs, ensuring safe and effective results.
A treatment plan should always be developed by a healthcare provider, who will consider factors such as age, current health condition, other existing conditions, and medications you’re already taking. For instance, certain heart medications may interact negatively with sildenafil, so those with heart conditions must consult a doctor before use.
Doctors may advise against using Sildenafil due to factors like specific health conditions or intolerance to certain components in the drug. Additionally, issues related to reproductive, circulatory, or cardiovascular health can lead to contraindications. To gain the most benefit from this medication, ensure you have consulted a professional to confirm it is safe and appropriate for you.
How to get a prescription for Sildenafil
To get a prescription for medication, you’ll need to schedule an appointment with a doctor. During the visit, the doctor will assess your condition, provide recommendations, and, if necessary, write a prescription so you can purchase the required medication from a pharmacy.
Keep in mind that prescription requirements may vary by location. In some regions, prescriptions must be issued on paper, while others accept electronic prescriptions. In the United States and Canada, doctors typically provide electronic prescriptions, which can be filled at any pharmacy.
What side effects should be considered?
Before you start taking Sildenafil, you should pay attention to the following possible side effects:
- Headache: some patients may have a headache after taking Sildenafil. This is usually temporary and goes away on its own.
- Redness of the face: some men may experience redness of the face caused by vasodilation.
- Runny nose: some patients may experience nasal congestion after taking Viagra.
- Indigestion: Some men may experience stomach discomfort, nausea, or vomiting.
- Muscle pain: some patients may have muscle pain or discomfort in the muscles.
However, it is worth noting that these side effects are usually temporary and disappear on their own. If the side effects become too unpleasant or prolonged, you should consult your doctor for advice.
It is worth remembering that the medication itself has a great effect on the kidneys, just like alcohol. When combined, a large load will be placed on the body. Not only the kidneys but also the heart will suffer, and tachycardia, dizziness, and shortness of breath may begin. With long-term use of Sildenafil, problems in the cardiovascular system may begin.
