Physicians worldwide recommend 25 mg blue colored Viagra to be administered not more than once in 24 hours time. The pill is to be taken half an hour before sexual interaction and it manifests its erection effects for about four hours. Apply sufficient sexual stimulation to evoke erection accelerating effect of the drug. Higher doses might be followed after the 25 mg dose which are 50 mg and 100 mg doses. Do not take Viagra if you previously suffered from hepatic, renal or kidney problems. The chief reason for this restriction is that drug administration in such diseased conditions could lead to impaired metabolism of the drug and thus a suspected condition of drug toxicity is highly likely. Alcohol is to be avoided when using the drug and other nitrates containing medications are to be avoided since co-administration of both could reinforce hypotension and a subsequent circulatory shock might ensue.
