Generic Viagra Without Prescription

How to buy Viagra online

Viagra is prescription-only medicine. Men who wish to buy Viagra or other ED medicine online from Dr Fox must first read medical information about erectile dysfunction and answer medical questions to check for eligibility. Your information is reviewed by our doctors and, if approved, tablets are despatched from our UK pharmacy. All men with ED should consult their doctor before obtaining treatment online.

Instructions:

Use Viagra as directed by your doctor.

Take Viagra by mouth with or without food. Viagra may not work as quickly if you take it with a high-fat meal.

Viagra is usually taken about 1 hour before sexual activity; however, it may be taken anywhere from 4 hours to a half hour before sexual activity. Talk with your doctor about the best way to take Viagra.

Viagra can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.

Do not take more than the recommended dose or take it more often than once daily, or as directed by your doctor.

If you miss a dose of Viagra and you still intend to engage in sexual activity, take it as soon as you remember. Continue to take it as directed by your doctor.

How does Viagra work?

Viagra works by increasing blood flow to the penis which helps men get and sustain an erection long enough for sex.

The active ingredient in Viagra is sildenafil, which is known medically as a PDE5 inhibitor. Sildenafil inhibits (blocks) an enzyme which regulates blood flow in the penis. PDE5 inhibitors multiply the natural process of arousal and increase blood flow to the penis in situations of sexual stimulation. Sildenafil helps to achieve an erection but relies on natural arousal as a trigger. It, and other PDE55 inhibitors such as tadalafil, vardenafil, and avanafil, support sexual relations when erections are failing.

How to take

The usual first starting dose of Viagra is one 50mg tablet, for men who have not used Viagra before, although men over the age of 65 years would normally start on the lowest dose tablet (25mg).

Viagra works in 30 to 60 minutes after it is taken and usually remains active for 4 hours.

If 50mg strength of tablet is highly effective subsequent doses may be reduced down to one 25mg tablet. If a 50mg tablet is ineffective, or the duration of activity is less than 4 hours, the dose can be increased to one 100mg tablet. Do not take Viagra more than once per day, or more than 100mg dose.

Arousal is required for the treatment to work. Viagra is most likely to be suitable if taken in situations where sexual arousal is expected within an hour or two of taking the tablet. Without sexual arousal there will be no benefit and the effect of the tablet will simply wear off after about 4 hours.

Avoid large meals, meals high in fat, excessive alcohol, and grapefruit as these can affect Viagra's efficacy (effectiveness).

Are there any side effects?

Viagra is remarkably well tolerated and free from significant side effects in the vast majority of men who take it. Viagra increases blood flow which can have adverse affects on other parts of the body, although these are usually mild. Most men who experience side effects carry on using Viagra regardless.

Slightly over 1% of men taking Viagra notice a bluish or yellowish discolouration of their vision. This is not in itself a cause for concern, and usually does not interfere with normal activity. It wears off after a few hours.

The most commonly reported adverse reactions in clinical studies were:

Headache is very common and can be treated with simple painkillers such as paracetamol.

Flushing (redness of the skin, typically over the cheeks or neck).

Indigestion (dyspepsia) - can be treated with indigestion remedies.

Visual disorders/distortion.

Nasal congestion - can be treated with menthol or eucalyptus inhalers, or other decongestant remedies.

Dizziness - if affected it is recommended not to drive or operate machinery.

Storage

Store Viagra at 77 degrees F (25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Viagra out of the reach of children and away from pets.
