Viagra Dosing and Administration are important to comply with. Canadian Health&Care Mall will introduce you the correct administration mode.The tablets are taken orally about 1 hour prior to sexual activity. Before you buy Viagra online, remember that the recommended dosage of the drug is 50 mg. In accordance with efficiency and tolerability of the preparation, the dose can be increased up to 100 mg or decreased to 25 mg. The maximum recommended dosage is 100 mg. The maximum recommended multiplicity of application is 1 time per day.
What happens if I exceed the recommended dosage?
Impaired renal function. In mild and moderate degree of renal insufficiency (Cl creatinine 30-80ml/min) the dose adjustment is not required in severe renal impairment (Cl creatinine).
Violations of the liver. Since the removal of Sildenafil in patients with impaired liver damage (particularly in cirrhosis), the dose of the drug should be reduced to 25 mg.
Viagra and other drugs
- When combined with ritonavir, the maximum single dose of sildenafil should not exceed 25 mg, and the multiplicity of application makes 1 time in 48 hours;
- In a joint application with inhibitors of cytochrome isoenzyme CYP3A4 (erythromycin, saquinavir, ketoconazole, itraconazole), the initial dose of Viagra should be 25 mg;
- To minimize the risk of postural hypotension in patients taking alpha-blockers, the treatment should be started only after the stabilization of hemodynamics in these patients. You should also consider reducing the starting dose of Sildenafil.
Elderly patients. The dose correction is not required.
Overdose
Studies have shown that when patients overdose Viagra they get more clear apparent side effects. 
In this case, the treatment must be used symptomatically. Dialysis is not effective because the active substance is active and rapidly bound to plasma proteins.
Volunteers have conducted a research – they took a single dose 800 mg of the PDE-5 inhibitor. Adverse effects were more common and serious. No specific antidote. In case of overdose, a symptomatic treatment is recommended, often in conditions of an intensive care unit. The matter is complicated by the fact that dialysis (blood purification) in this case is not effective as Sildenafil is tightly bound to plasma proteins and is excreted in the urine.
Any negative impact on the ability to drive is not revealed, but taking possible side effects into consideration, you should pay more attention to a car driving and operations with mechanisms at least for some time after taking Viagra pills.
How to get the best results?
Taking Viagra for men, do not forget the following tips:
- You must be in the mood “for that”: this drug starts working only when you are sexually excited. After each sexual act your erection will pass off, as it usually happens, and occurs if you have a sexual arousal again;
- Things should be done when the time is appropriate: sildenafil works for four hours, you will agree that this is a long time to completely relax, apart from minor things and focus all attention on getting the feeling of satisfaction. Four hours Viagra can help as many times as you need. You should take a pill for 30-60 minutes prior to the scheduled intimacy. You may find out that the drug works faster. One-third of men’s action starts after about 15 minutes. The optimal administration of this preparation is in the prescribed dosage about an hour before sex;
- Be careful with meals: the medicine can help you have an erection regardless of the meal. That means you can quite easily arrange a romantic dinner, during which you discreetly take a stimulant. The only thing we should not forget that if you previously ate a solid meal, the effect may come later, but with the same result;
- Be careful with overdose: the drug helps most men right from the first or second dose. However, some men need more attempts. Do not give up. Sildenafil helps men solve problems with erection. Try to take the medication the next time. Remember that the maximum dose of the drug is 100 mg per day. Viagra can be taken every day without fear of any serious consequences. If the effect of these pills does not satisfy you, consult your doctor. Often the correct selection of the dose changes everything for the better.
