Benzocaine
Benzocaine is a surface local anaesthetic used in gels for mouth pain and sore spots; PockDose lists it as Mucopain, a 20% tube.
Benzocaine is a numbing agent that works only at the surface. It is an ester-type local anaesthetic: it blocks sodium channels in nerve endings so they stop passing pain signals to the brain. It barely soaks past the skin or the lining of the mouth, which is why it suits sore patches on the surface and cannot replace the deeper numbing a dentist uses.
Where benzocaine turns up
Mouth gels for ulcers and gum soreness are the best-known form. Benzocaine is also in lozenges and throat sprays for sore throat, in creams and sprays for sunburn, insect bites and minor skin irritation, and in some haemorrhoid products. The numbness fades as the drug is cleared from the spot, which takes a short while, and nothing about the gel repairs the sore underneath.
The benzocaine listing at PockDose
There is one: Mucopain, a 20% benzocaine gel in tubes, listed for mouth pain, minor mouth irritation and sore throat. Benzocaine is the only active ingredient in Mucopain. The tubes come in several pack sizes, so the choice here is how many tubes to order rather than which strength.
Who should take care
People who are sensitive to other ester anaesthetics (procaine, tetracaine) or to PABA, a compound found in some sunscreens, can react to benzocaine as well. Benzocaine can also lower the effect of sulfonamide antibiotics when used on large areas.
The most important risk is methaemoglobinaemia, a rare condition where the blood carries too little oxygen. It is most often reported in infants and young children, in smokers, and in people with asthma, bronchitis, emphysema or heart disease. The signs are pale, grey or blue skin, lips or nail beds, shortness of breath, headache, fast heartbeat and fatigue, appearing within minutes to two hours of use. That calls for urgent treatment. For this reason benzocaine gels are not for teething babies or children under 2.
The common effects are milder: a sting or burn where it goes on, redness, itching and the numb feeling itself. A widespread rash or swelling of the face or tongue points to an allergic reaction.
Is Benzocaine available to order in Hong Kong?
Benzocaine can be ordered online from PockDose with delivery to Hong Kong, which lists Mucopain in a 20% tube. Orders arrive in plain, unbranded packaging, and nothing on the outside reveals what is inside.
How are Benzocaine prices shown?
Mucopain is priced per pack: its page lists every strength and pack size with the current price in HKD or your chosen currency.
Do I need a prescription to order Benzocaine?
PockDose does not ask you to upload a prescription when you order benzocaine. See the ordering FAQ for details.
Is benzocaine the same as lidocaine?
No, they are different anaesthetics. Benzocaine is an ester that works on the surface and is mostly used in gels and lozenges. Lidocaine is an amide that also works deeper and is used in injections. Benzocaine is more likely to cause skin allergy.
Why is benzocaine not used for teething babies?
Benzocaine on the gums of a baby or child under 2 carries a risk of methaemoglobinaemia, and it gives little lasting relief because saliva washes it away. Cold teething rings or a clean cold cloth are the common alternatives.
Can benzocaine be used on skin as well as in the mouth?
Yes, it appears in creams and sprays for sunburn, insect bites and minor skin irritation. The product here is a gel made for sore spots in the mouth, so keep it to that use.
