Description
Benzocaine is the only effective ingredient in oral therapy, which can relieve sore throat or solve oral pain caused by problems such as colds, ulcers and teething. It can also be treated with other active ingredients in the mouth, not only to relieve pain in the mouth and throat, but also to protect sensitive areas, provide a soothing coating, or relieve dryness.
Although oral discomfort treatment with benzocaine is used inside and around the mouth, there are other topical benzocaine drugs that can only be used outside the body or outside the body, but not near the mouth or inside the mouth.
For example, benzocaine can be found in vaginal drugs containing more than one type of external analgesic ingredient, or in the treatment of an active ingredient in acne. Benzocaine can also be used as a topical analgesic, which not only relieves skin irritation, pain and itching, but also contains other active ingredients that kill bacteria and prevent infection.
Applicant
Benzocaine is a local anesthetic used for minor procedures involving the throat and mouth, including insertion of a catheter. It numbs affected parts of the body. Benzocaine is only used when needed. If one dose is missing, it will not cause adverse effects except uncomfortable. If you miss a dose of benzocaine, don’t use too much when you use it next time. If too much benzocaine is used, there will be more numbness than usual.
Benzocaine is also used in Viagra to maintain an erection of the penis during sexual intercourse. Sports athletes also have a great demand for benzocaine powder, especially for swimmers and divers. They can also be purchased from open sources such as medical stores, or they can be purchased from a variety of websites that are now on the rise. In addition to lidocaine powder and benzocaine powder, it can be selected from liquid and tablet forms.
