2. Leading Local Anesthetics Dyclonine •Rapid onset, medium duration. •Caution: None of special concern. 3. Other Local Anesthetics (Not Recommended) Camphor •Occasionally used but not recommended due to potential toxicity. •Provides a cooling sensation but has no true anesthetic effect. Menthol •Provides cooling relief but is not as effective as standard anesthetics. Phenol •Can numb the area but is less effective and incomplete. 4. Topical Anesthetics for Specific Uses Toothache (Oral use) •First choice: Benzocaine (5–20% concentration) •Common brands: Anbesol, Orajel, Maximum Strength Gel. •Reason: Most effective and safest option with the lowest side effect potential. •Second choice: Benzocaine (5–10% concentration) •Common brands: Anbesol Liquid, Baby Orajel. •Reason: Less potent but still useful if the first choice is unavailable. Sore Throat (Lozenges) •First choice: Dyclonine (2–3 mg) •Common brands: Sucrets, Maximum Strength Sore Throat. •Reason: Effective for temporary pain relief. •Second choice: Benzocaine (5.3 mg) •Common brands: Cepacol, Chloraseptic Cool Mint. •Reason: Good alternative, but less effective than Dyclonine. •Caution: Potential allergic reactions in sensitive individuals. 5. Local Anesthetics for Pain Relief Sunburn, Burns, Ingrown Toenail, Insect Bites/Stings •First choice: Benzocaine (10–20% concentration) •Common brands: Americaine, Solarcaine, Sting Relief. •Reason: Most effective local anesthetic. •Caution: Possible sensitivity reactions. •Second choice: Lidocaine or Dibucaine (1–2.5% concentration) •Common brands: Nupercainal Ointment, Lanacane. •Reason: Good alternative but higher risk of sensitivity reactions. 6. Cold Sores, Canker Sores, Fever Blisters •First choice: Benzocaine (5–20% concentration) •Common brands: Zilactin, Anbesol, Orajel. •Reason: Effective for reducing pain and discomfort. •Caution: Use caution with open sores to prevent irritation. •Second choice: Salicylic Acid (5–20% concentration) •Common brands: Zilactin, Campho-Phenique. •Reason: Not FDA-approved for oral use but used for similar applications. 7. Local Anesthetics for Itch Relief Anal Itch, Vaginal Itch, etc. •First choice: Hydrocortisone (0.5–1% concentration) •Reason: Best for reducing inflammation and itching. •Second choice: Lidocaine or Dibucaine (1–2.5% concentration) •Reason: Effective but higher risk of allergic reactions.
