If you experience any of the more serious side effects listed above (e.g. strong dizziness, vomiting, chest pain, numbness of limbs, etc.), we strongly recommend that you refrain from sexual activity. Less serious side effects, such as mild to moderate headache, indigestion or facial flushing don’t call for abstinence – but you can definitely consider making the intercourse less physically challenging, if your partner don’t mind doing all the work.Effects of Viagra on Blood Pressure: Single oral doses of sildenafil (100 mg) administered to healthy volunteers produced decreases in sitting blood pressure (mean maximum decrease in systolic/diastolic blood pressure of 8.3/5.3 mmHg). The decrease in sitting blood pressure was most notable approximately 1–2 hours after dosing, and was not different than placebo at 8 hours. Similar effects on blood pressure were noted with 25 mg, 50 mg and 100 mg of Viagra, therefore the effects are not related to dose or plasma levels within this dosage range. Larger effects were recorded among patients receiving concomitant nitrates [see Contraindications (4.1)]. foods for ed Carcinogenesis
Physicians should consider whether their patients with underlying NAION risk factors could be adversely affected by use of PDE5 inhibitors. Individuals who have already experienced NAION are at increased risk of NAION recurrence. Therefore, PDE5 inhibitors, including Cialis, should be used with caution in these patients and only when the anticipated benefits outweigh the risks. Individuals with "crowded" optic disc are also considered at greater risk for NAION compared to the general population; however, evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including Cialis, for this uncommon condition.

In volunteers with severe (CLcr <30 mL/min) renal impairment, sildenafil clearance was reduced, resulting in approximately doubling of AUC and Cmax compared to age-matched volunteers with no renal impairment [see Dosage and Administration (2.5), and Use in Specific Populations (8.6)].Alcohol is another chemical that dilates blood vessels. According to the NIH, neither Viagra nor Levitra strengthened the hypotensive effects of alcohol. However, when it’s mixed with substantial amounts of alcohol, Cialis could lead to potential low blood pressure symptoms when you stand up. These symptoms include dizziness and headache. The NIH also points out that Cialis and Levitra, when taken with alcohol, do not lead to a change in the levels of alcohol or the drug in the blood.
There are limited data from the use of tadalafil in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3). As a precautionary measure, it is preferable to avoid the use of CIALIS during pregnancy. how to get viagra online
