What is it?
Viagra Professional is a sublingual formulation of sildenafil citrate marketed for adult men with erectile dysfunction. The tablet is placed under the tongue, where it dissolves and is absorbed directly through the oral mucosa, bypassing the slower gastrointestinal route of conventional tablets. The product positions itself as a faster-onset alternative for users who want a shorter delay between dose and effect. The active molecule and overall safety profile match standard sildenafil products.
Active ingredients
Each Viagra Professional tablet contains 100mg of sildenafil citrate. The selective PDE5 inhibition mechanism is identical to other sildenafil products, but the route of absorption differs. According to product literature, sublingual administration can shorten the time to peak plasma concentration relative to swallowing, which translates into a slightly earlier onset. The chemical structure and metabolic profile of sildenafil itself are unchanged.
Forms and dosages
Viagra Professional is supplied as 100mg sublingual tablets that should be placed under the tongue and allowed to dissolve completely without swallowing. The recommended dose is one tablet approximately 15 to 30 minutes before planned sexual activity, taken without water. Maximum dosing is one tablet per 24 hours. Eating, drinking and smoking should be avoided for several minutes after dosing to allow full mucosal absorption.
Indications
Viagra Professional is intended for adult men with erectile dysfunction. It is not indicated for women, paediatric patients or men without a clinical diagnosis. According to general prescribing principles for sildenafil, the cardiovascular fitness and current medication list of the patient should be reviewed before use. The 100mg-only presentation is not suited to patients who would normally require lower starting doses for tolerability reasons.
How it works
Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood inflow. The sublingual route delivers the molecule directly into systemic circulation through the oral mucosa, avoiding first-pass metabolism in the liver to a partial degree. According to product literature, this can shorten onset of action to 15 to 30 minutes versus 30 to 60 for conventional tablets.
Frequently asked questions
How is Viagra Professional different from regular Viagra? ▾
Both contain sildenafil citrate 100mg and produce the same therapeutic effect. The difference is the route of administration: Viagra Professional is taken sublingually (dissolved under the tongue), while regular Viagra is swallowed whole. Sublingual administration can shorten the onset of action by approximately 15 to 30 minutes, according to product literature, because absorption through the oral mucosa bypasses part of the gastrointestinal route.
How do I take a sublingual tablet correctly? ▾
Place the Viagra Professional tablet under your tongue and let it dissolve completely without swallowing or chewing. Avoid drinking, eating or smoking for several minutes to allow full absorption through the oral mucosa. The recommended timing is 15 to 30 minutes before sexual activity. According to product literature, swallowing the tablet whole reduces the speed advantage of the sublingual format.
Is sublingual sildenafil safer than swallowed sildenafil? ▾
The systemic exposure and overall safety profile are comparable to swallowed sildenafil at the same dose. The sublingual route may slightly reduce hepatic first-pass metabolism, but does not change contraindications such as concurrent use of nitrates or severe cardiovascular disease. According to general prescribing principles for sildenafil, the same medical evaluation should precede use of either form.
Can Viagra Professional be taken with food? ▾
Because the tablet is absorbed through the oral mucosa rather than the stomach, food intake has less impact on its onset of action than with swallowed Viagra. However, eating or drinking immediately after administration can wash the unabsorbed portion into the stomach and reduce the speed advantage. According to product literature, several minutes without food and drink after dosing are recommended.
What contraindications apply to Viagra Professional? ▾
Contraindications match those of all sildenafil products: concurrent use of organic nitrates or guanylate cyclase stimulators is contraindicated due to the risk of severe hypotension. Caution is required in patients with severe cardiovascular disease, recent stroke or heart attack, severe hepatic impairment and known hypersensitivity to sildenafil. According to the prescribing information, full medical history must be reviewed before initiation.
