Learn about Sildenafil (Generic Viagra)

Sildenafil is the leading treatment for erectile dysfunction, and it's the generic version of brand-name Viagra. Sildenafil gives you all the benefits of Viagra, simply packaged as a generic drug. Sildenafil is highly effective, comes with minimal side effects, and is safe to take daily. Like most generic versions, sildenafil is more affordable, helping you overcome your bedroom troubles without breaking the bank.

Sildenafil works best when you take it 30 to 60 minutes before sex. By giving it enough time to work, you'll be maximizing the benefits. Sildenafil lasts up to 4 hours, giving you plenty of time for enjoyment. During this time, you'll only get an erection when you're aroused.

Eating lighter meals or taking sildenafil on an empty stomach gives you the best results. Although sildenafil can be taken with food, keep in mind that heavy, high-fat meals can delay how long it takes to work.

A drink or two probably won't hurt, but alcohol can reduce the effectiveness of sildenafil. You'll want to avoid consuming too much alcohol as this interaction can cause low blood pressure and dangerous complications.

The cost of sildenafil may vary based on dose and quantity, but one thing is for sure—Mail My Meds offers the most affordable prices around. Choosing generic over brand name already helps you save big. We also offer fast and secure delivery to ensure you get consistent results.

Sildenafil may cause side effects such as dizziness, nausea, muscle aches, and flushing. Other commonly reported side effects include headaches and nasal congestion.

Avoiding grapefruit and grapefruit juice helps lower your risk of adverse effects. Do not take sildenafil with nitrates, as doing so may result in a sudden blood pressure drop.

Common questions about Sildenafil (Generic Viagra)

Sildenafil is the generic version, and Viagra is the brand name. Both meds achieve the same beneficial results for men struggling with erectile dysfunction. Sildenafil and Viagra use the same active ingredients, making these two drugs equally effective.

The main differences between sildenafil and Viagra are the appearance and cost. Brand-name Viagra will sport the iconic blue diamond shape, while sildenafil pills may not be instantly recognizable. Still, sildenafil and Viagra accomplish the same results, just with different branding.

Sildenafil and Viagra are widely counterfeited online. Due to its popularity, many sites sell fake sildenafil, often mislabeling herbal supplements as sildenafil or adding excessive amounts of sildenafil in their herbal products.

Taking counterfeit medications can seriously harm your health, which is why it's extremely important to use a safe online service like Mail My Meds.

Sildenafil is available by prescription only, so avoid any pharmacy selling it over the counter. To safely buy sildenafil online, always use a pharmacy such as Mail My Meds that requires a valid prescription.

You can also work with your healthcare provider to confirm an online pharmacy's legitimacy. We also advise you to read the website's privacy policy to ensure your financial and medical information is handled safely.

Sildenafil works together with your sexual arousal process to enhance erections. Let's first take a look at how an erection takes place to fully understand how sildenafil works.

Getting in the mood causes a chain reaction. First, the body releases nitric oxide, which produces cGMP that relaxes the blood vessels and increases blood flow to the penis. Then, an enzyme called PDE5 kicks in and breaks down the cGMP, stopping the erection. Sildenafil blocks this enzyme and lets more cGMP build up, resulting in more blood flow to the penis for longer, which means stronger hard-ons every time you take a pill.

Most men start at 50 mg and find that it's the perfect dosage. Those who need a stronger dose can go up to 100 mg, although even 25 mg is effective enough for lots of men.

To prevent side effects, avoid taking more than one tablet a day. If you're taking other medications, let your doctor know so that you can be prescribed the appropriate dose to avoid drug interactions.

It's a good thing you asked. Sildenafil is prescription-only, and there's a reason. Being a powerful medication, there's the potential that sildenafil may be misused or overused as an OTC drug. If you find OTC sildenafil online, it's not legitimate and will likely contain ingredients that have not been approved by the FDA.

For safe and approved sildenafil, you'll want to use a reputable online service like Mail My Meds. We always require a verified prescription for sildenafil, and our team of licensed medical professionals ensures your prescription is tailored to your needs.

Sildenafil does have a few interactions you should avoid. The main medications to avoid while taking sildenafil are nitrate-related drugs and alpha-blockers. Drugs containing nitrates are often used for chest pain, while alpha-blockers are generally prescribed for high blood pressure. These types of drugs lower your blood pressure, but so does sildenafil. Taking them together can cause a dangerous drop in your blood pressure, which can cause you to feel dizzy and even pass out.

We also advise that you avoid grapefruit-related products and alcohol while taking sildenafil. Grapefruit is known to affect how your body absorbs sildenafil, and alcohol can reduce sexual function, even in men without ED. By avoiding such interactions, you'll ensure sildenafil works consistently and reliably.

When it comes to getting the most out of your sildenafil tablets, timing is (almost) everything. You'll want to always take your dose at least 30 minutes before having sex, which gives the body enough time to absorb the medication and put it to use. Because sildenafil is used as needed, planning ahead ensures peak performance when the moment calls for it.

Additionally, don't let food and drug interactions spoil the fun. Taking sildenafil on an empty stomach is best. If you have to eat, go for a lighter meal because high-fat meals can delay sildenafil's onset. Finally, taking more than prescribed is never a good idea. Always follow your prescribed dosage guidelines to maximize the benefits of sildenafil.
