Take nitrates, such as nitroglycerin or isosorbide mononitrate (Monoket) Take riociguat (Adempas) or other sGC stimulators You’ve probably heard of Viagra being commonly referred to as “the little blue pill”, and its distinctive blue colour is synonymous with the treatment of erectile dysfunction (ED). Sildenafil, the active ingredient in Viagra, is manufactured in a variety of colours, but most commonly in either blue or white.
- Sildenafil tablets are often stored in their original packaging to avoid contamination.
- Use only the amount prescribed; more does not mean better results.
- Sildenafil helps improve erectile function but doesn’t increase libido.
- The tablets are designed for rapid and effective absorption.
- Always inform your doctor about existing health conditions before use.
- Some brands of sildenafil are marketed as "white tablets" for easy recognition.
- The medication can cause a mild increase in blood flow to other body parts.
- Avoid caffeine or heavy meals before taking sildenafil for better results.
- The safety and efficacy of sildenafil are supported by numerous clinical trials.
- Never take expired sildenafil tablets, as their safety can’t be guaranteed.
- Regular blood pressure checks are recommended when using sildenafil long-term.
But does the colour and shape of your pill make a difference in the effectiveness of the treatment? When Viagra was first approved as a treatment for ED in 1998, it was marketed as “the little blue pill”. The small, blue, diamond-shaped pill was patented by Viagra, meaning that both its appearance and active ingredient were exclusive to Viagra and couldn’t be copied by other manufacturers. After Pfizer’s patent for Viagra expired in 2013, sildenafil (the active ingredient in Viagra) was made more widely available for manufacturing by other companies. Nowadays, many manufacturers continue to make sildenafil as a blue-coloured pill, but it also comes in a variety of other shapes and colours, and is sometimes manufactured as a white pill. This is commonplace, and, as with many types of generic medication, you may find that the appearance of your pills sometimes changes each time you order them.
