Product Details
Viagra 100 mg is labeled as containing sildenafil citrate equivalent to 100 mg sildenafil per tablet. This listing is for a 2-tablet pack. Sildenafil is a PDE5 inhibitor used for erectile dysfunction and supports increased blood flow during sexual stimulation. Sexual stimulation is still required for an erection to occur.
The 100 mg strength is the maximum recommended sildenafil dose and may not be appropriate for everyone. Individual response can vary depending on health conditions, other medicines and tolerability. Follow the directions provided by a licensed healthcare professional and do not take additional tablets because the expected response has not occurred immediately.
Before use, review the supplied product information and check the strength, packaging and expiry date. Sildenafil can interact with some medicines, particularly nitrates, riociguat and certain blood-pressure medicines. Seek professional advice if you are unsure whether sildenafil is suitable for you.
Storage & Handling
Keep the tablets in their original packaging in a cool, dry place away from excessive heat, moisture and direct sunlight. Keep medicines out of reach of children and pets. Do not use tablets that appear damaged, discolored or are past the expiry date shown on the packaging.
