Viagra and additional oral medicine for erectile dysfunction

By Mayo Clinic Staff The first line of treatment for erectile dysfunction is frequently oral medicines. These drugs perform well and have few adverse effects for the majority of men who struggle to maintain an erection strong enough for intercourse (erectile dysfunction).

Oral drugs such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis), and avanafil (Standard) work to treat erectile dysfunction by boosting the effects of nitric oxide, a substance your body naturally generates that relaxes the penile muscles. As a result of the increased blood flow, you can respond to sexual stimulation by getting an erection.

Differentiating oral medicines

Each oral drug has a somewhat different chemical composition even though they all function in a similar fashion. These insignificant variations have an impact on how each prescription functions, including how quickly it takes action and wears off as well as any potential side effects. These elements, together with any additional medical issues you may have and any drug interactions, will be taken into account by your doctor.

Viagra, or sildenafil. One hour prior to having sex, take this drug on an empty stomach for best results. If you suffer from mild to moderate erectile dysfunction, it remains effective for at least four to five hours.

Vardenafil (Staxyn, Levitra). This medicine can be taken with or without food and is most effective when taken an hour prior to intercourse. It could not absorb as quickly if you eat a meal that is high in fat.

If you have mild to severe erectile dysfunction, vardenafil will work for at least four to five hours. A more recent medicine formulation that dissolves on the tongue might function more quickly than a pill that you swallow.

Cialis is tadalafil. This drug should be consumed one to two hours prior to having intercourse, with or without meals. For up to 36 hours, it works. It can be consumed either in a little daily dose or a bigger quantity if required.

Standard (Avanafil). Depending on the dosage, this medicine may be taken with or without food 30 minutes prior to sexual activity. It might last for six hours.

The American College of Physicians advises making the decision depending on your preferences, including the cost, simplicity of use, duration of the drug's benefits, and adverse effects because both medications are similarly effective. Sildenafil, vardenafil, and tadalafil are all available in generic form.

The majority of guys who take oral erectile dysfunction drugs don't have any issues with side effects. When side effects do materialize, they may comprise:

Flushing Headache Indigestion

A blue tint to the eyesight, sensitivity to light, or impaired vision are some examples of visual alterations.

Rarely, more severe side effects can develop, such as:

loss of eyesight or hearing. Following the use of one of these drugs, some men experienced an unexpected loss of hearing or eyesight. It is unclear, however, whether vision or hearing loss was a direct result of using the medicine or was brought on by a pre-existing illness. Seek immediate medical assistance if you're taking an oral erectile dysfunction prescription and experience a sudden loss of hearing or vision.

an erection that does not spontaneously disappear. This uncommon ailment, known as priapism, can be excruciatingly painful and calls for medical attention to prevent penile injury. If your erection lasts longer than four hours, you should consult a doctor right once.

Online purchase of oral erectile dysfunction drugs

Online frauds abound, and erectile dysfunction treatments are big business. If you do purchase prescription drugs online:

Verify the legitimacy of an online pharmacy. If there is no phone number for the pharmacy, the rates appear too good to be true, or you are told a prescription is not required, never order pharmaceuticals from an online pharmacy. Some unlawful businesses sell potentially harmful or inefficient counterfeit copies of prescription drugs. If you're in the United States, you may find out if an online pharmacy has a valid license by contacting the National Association of Boards of Pharmacy.

Make sure the prescription and dosage are correct. Make sure the drug you order and receive in the mail is the precise one your doctor ordered, both in terms of dosage and type.

Don't fall for the "herbal Viagra" con. Never take any drugs that advertise as the "herbal" or over-the-counter replacement for an oral erectile dysfunction drug. These aren't a good substitute, and some of them include dangerous ingredients.
