How SEX affects the body
Can I have Viagra and Sildenafil?
It is the same thing. Sildenafil is the active substance of Viagra, while Viagra is the commercial name. There are also generics of sildenafil available. Teva’s generic Viagra has launched already in December 2017 in the United States. Pfizer recently started to sell the new generic version of Viagra. Not only the generic is cheaper than the original drug but it is also easy to buy over the internet from legitimate UK pharmacy’s. Thus stopping any awkward face to face conversations.
The legend of the blue pill remains but generic alternatives can be used with the same effects, administering the same medicine (sildenafil) but with some extra money in the pockets of the patients.
So, how many strengths of Viagra/Sildenafil are there?
The original Viagra comes in three concentrations: 25, 50 and 50 mg.
For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, VIAGRA may be taken anywhere from 4 hours to 0.5 hours before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.4
For Sildenafil tablets, it is the same.
I take 50 mg of sildenafil. What happens?
Immediately after ingestion of one tablet, Sildenafil starts to absorb into the body.
Sildenafil has a rapid onset of action.
Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. When sildenafil is taken with a high-fat meal, the rate of absorption is reduced, with a mean delay in Tmax of 60 minutes and a mean reduction in Cmax of 29%.7
Pharmacokinetic studies have supported the suitability of single oral doses of sildenafil for an as-needed and on-demand treatment for erectile dysfunction. In healthy volunteers, sildenafil doses are absorbed rapidly, with maximum plasma concentrations achieved within a median time of 1 h (range 0.5–2 h) after dosing.
The terminal half-life of sildenafil is 3–5 h.
In a two randomised, double-blind, placebo-controlled, two-way crossover studies were conducted in men with erectile dysfunction of no known organic cause, sildenafil proved to be an effective oral treatment for erectile dysfunction that produces a penetrative erection as early as 12 min and for most patients, within 30 min after dosing, and a duration of action lasting at least 4 h.8
The volume of distribution and clearance characteristics of sildenafil resulted in an apparent terminal half-life ranging from 3 to 4 h. The half-life of sildenafil provides for an appropriate duration of therapeutic effect and also prevents drug accumulation with chronic once-daily use.
In a 4-year study, only 3.8% of the men had 1 or more adverse events that led to changes in dosing. Of the 47 events that were documented during the study period, headache and dyspepsia were most common (10 events each), followed by rhinitis (6 events), flushing (5 events), abnormal vision (4 events), dizziness (3 events), and 1 report each of mild palpitations, moderate tachycardia, diarrhea, nausea, myalgia, hypertonia, respiratory disorder, conjunctivitis, and photophobia. Of the few cardiovascular events determined by the investigator to be treatment-related (4 cases of mild flushing and 1 each of moderate flushing, mild palpitations, and moderate tachycardia), only 1 led to permanent discontinuation of treatment. In this case, the man experienced mild flushing with the first dose of sildenafil 100 mg but continued therapy after a dose reduction. Two other cardiovascular events led to temporary discontinuation (mild flushing and moderate tachycardia), and the remainder were addressed with a change in dosing. 9
So, how often can I take Sildenafil?
The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity.
You can take one tablet daily if you’re in the mood for love.
Sildenafil usually should not be taken more than once.
You should not take sildenafil every day if you do not intend to have sex every day. Sildenafil does not have a cumulative effect, which means that the active substance is not accumulated in the tissues of your penis even if you take it daily. Thus, you will not have better or constant erections just because you ingested more Sildenafil “in advance”.
Sildenafil/Viagra just does not work that way.
We strongly recommend taking a pill only on those days on which you intend to have a sexual intercourse.
Is it safe?
Yes, Viagra is a safe drug. Safety was proven in a number of clinical studies. Sildenafil was administered to more than 9500 patients aged 18-87.4
The safety of Viagra has not been studied and therefore is contraindicated in the following groups: a patient with severe hepatic impairment, a patient with hypotension (blood pressure <90/50 mmHg), a recent history of stroke and known hereditary degenerative retinal disorders such as retinitis pigmentosa.
The most common adverse reactions include a headache, flushing, dyspepsia, nasal congestion, dizziness, nausea and altered vision.
As dizziness was reported in clinical trials, it is better not to drive or to manipulate any operating machinery immediately after taking Viagra.
From all the drugs belonging to the class of PDE5 inhibitors, Viagra is preferred if you want to minimize side effects as it gets out of your system faster.
Contraindications
Consistent with its known effects on the nitric oxide/cGMP pathway, Sildenafil was shown to potentiate the hypotensive effects of nitrates, and its administration to patients who are using organic nitrates, either regularly and/or intermittently, in any form is therefore contraindicated. After patients have taken sildenafil, it is unknown when nitrates, if necessary, can be safely administered.
Sildenafil is contraindicated in patients with a known hypersensitivity to any component of the tablet.
Precautions
You cannot take any other PDE5 inhibitors on the same day when administering sildenafil, as there are risks related to overdosing. Please be careful when taking Cialis or tadalafil. You must wait 48 hours for wash-out before taking sildenafil. Consult our doctor for any additional questions related to any drug interactions.
Please also consider your degree of cardiac risks associated with the sexual activity.
If you are in the case of co-administering substances known to lead to symptomatic hypotension (blood pressure <90/50 mmHg), do not take Viagra.
If using alpha- blockers, you should address to your doctor prior to taking Viagra.
Sildenafil or Viagra cannot be administrated with nitric oxide donors or nitrated in any form (Nitroglycerin Isosorbide, Nitroprusside, Amyl nitrite or amyl nitrate). Nitrate esters are commonly used in the treatment of angina pectoris, or “chest pain”, myocardial infarction, and congestive heart failure. The combination of nitrates and Viagra can lead to a dangerous fall in your blood pressure.10
Also, do not take nitrate-containing medicines up to 24 hours after you take Viagra.
If you are not certain, it is better to ask the doctor or the pharmacist.
Do not take Viagra if you are taking riociguat used to treat high pressure in the lungs and high pressure in the lungs secondary to blood clots, as their hypotensive effects may be increased by Viagra.
If you have a severe heart problem if you suffered a stroke or heart attack, or if you have a severe liver problem, it is better to refer to your doctor or pharmacist.
A regular use of sildenafil can affect me in any way?
A regular use of the drug helps a patient to be successful in the intimate sphere. Once again, we want to assure all men that even the long and frequent reception of Viagra can have absolutely no negative impact on their body.
What if I experience a problem?
If any unpleasant effects appear, please address directly to our pharmacy and to our doctor at phone number 0161 707 6800.
Viagra is the ideal oral treatment with plenty of advantages: great compliance in administration, a reasonably short time of action onset, reliable efficacy, good tolerability, high selectivity for the site of action, lack of central nervous system effects, rapid absorption that yields prompt onset of action and a plasma half-life that produces an appropriate duration of action while avoiding accumulation upon repeated once-daily use.
Still, we advise to report us any unusual reaction or any unusual effect.
And, to take sildenafil exactly as your doctor tell you to.
Also, if you feel the tablets are too strong for you, your dose may be reduced.
Please let us know if this is the case.
So, what should be my real expectations after taking Viagra for the first time?
Viagra will not make your penis larger and neither won’t decrease premature ejaculation. It will, however, decrease your refractory time, the time required to achieve a subsequent erection after ejaculation. And it will allow a firmer erection with less stimulation and will make possible a few more erection during the interval of 4-5 hours postdose. And the good news is that you can order it online. An evaluation from our pharmacist is necessary to confirm if Viagra/sildenafil is the appropriate medicinal product for you.
In summary…
The definition of erectile dysfunction can be different for every guy. Also, the treatment can be different depending on a lot of factors.
Remember, this medicine is for you. Do not share it with others.
Being a Viagra patient for the first time, you may experience unwanted effects. They are transitory and often improve as your body adjusts to the new medicine.
If you have any questions related to this medicine, please write us or call the number
