Unlike general anesthetics, local anesthetics like Lidocaine and Tetracaine work by numbing one particular area. They do not produce unconsciousness. They are applied topically, and they stop the nerve endings from sending back pain signals to the brain. They can be useful during surgeries or medical procedures where the person could become uncomfortable by the pain of the treatment.
These anesthetics may be re-applied over the course of the procedure to maintain numbness, and overdose on these drugs is rare. When used properly as a topical medication, these medications are safe and can be used in tandem with general anesthetics to protect the patient from pain. These drugs are usually given by a medical professional, but prescription forms of the drug can be taken home by a patient as well. In these cases, they are most often given as creams and patches.
Lidocaine and Tetracaine can be a valuable resource for anyone suffering from skin conditions or other painful issues. They can numb the area while painkillers set in, or be used throughout the day to prevent pain. If your doctor has prescribed a Lidocaine and Tetracaine patch/cream, be sure to follow all their given instructions on how to use it.
This drug may have side effects beyond the initial numbness. Many of these may go away the longer you use this drug, as your body gets used the medication and you learn to ignore them. If you experience any side effects that persist into your daily life and make your regular routine difficult, talk to your doctor. They may be able to give you additional medications or tips on how to cope with the side effects.
Most side effects do not require medical attention, but anything unusual or painful should be reported back to your doctor. Here are some of the most common side effects. Please note that this list is not exhaustive, and there is a chance you will experience things not on this list. If you have questions about this drug and its side effects, speak to your doctor or pharmacist to get more information.
These side effects are normal, and you may not experience them at all. Many patients report little to no side effects when using topical Lidocaine and Tetracaine.
Some side effects may be a sign that something is wrong with your treatment. If you experience any of the following side effects, contact your doctor as soon as possible. They may be symptoms of an allergic reaction to this drug. If you believe your life is in danger at any point, get medical help immediately. Allergic reactions are not to be taken lightly, and you should always assess the risk of allergies when using a drug for the first time.
Be sure to wipe off any cream and take off any patches if you experience these side effects. Do not attempt to re-apply the cream/patch on another part of the body, because that will cause the allergic reaction to occur elsewhere.
Any additional side effects that resemble allergic reactions (swelling of the face/mouth, trouble breathing), should also be monitored and reported back to a medical professional. With topical medications, these symptoms are less likely, but they should never be ruled out. During the first week of your treatment with this drug, keep a list of all potential side effects. Be sure to mention any unusual ones to your doctor during your next visit. While many people are able to use Lidocaine and Tetracaine without issue, some people react adversely to this drug.
This drug may be used differently depending on whether or not you're using the cream or the patch. In any case, follow your doctor's instructions when using this drug. If you think you might need to increase/decrease your dose, be sure to mention this before any surgery/procedure begins. The doctor will apply the patch or cream about 10-15 minutes before the procedure. If you still have feeling after 30 minutes, tell your doctor.
Avoid touching your face or eyes after you've had contact with this drug. The drug may carry over and cause numbness in those areas, and rubbing at your face when it's numbed can cause damage. Do not touch the numbed area or scratch at it while it is numb. This may cause damage you won't feel until the drug has worn off.
If you need to take home this drug at any point, your doctor may give you an information leaflet or the manufacturer's information on this drug. Be sure to read it over before you leave, and ask them about anything you don't understand. Talk to your pharmacist if you have further questions about how this drug is used.
This drug may interact with other medications on your prescription list. It may also have interactions with over the counter drugs and herbal remedies, so always mention those to your doctor when listing your taken medications.

If it is necessary that you take both drugs, your doctor may lower your dose of one or both medications.
As a local anesthetic, Lidocaine and Tetracaine do not interact heavily with many medications. However, an anti-rhythmic medication called Amidodarone does interact heavily with Lidocaine. Avoid taking this medication if possible or discuss alternative drugs with your doctor. If you only need to take Lidocaine and Tetracaine for a short period of time, you should be able to re-start your medication once your Lidocaine prescription ends. There might be other interactions not listed here, so be sure to go over all possible interactions with your doctor before administering this medication.
All drugs come with risks, so be sure to assess any that apply to you carefully. Your doctor may go over these risks with you, so be sure to ask questions and mention any relevant conditions.

Tell your doctor right away if you experience allergy symptoms like swelling, redness, rash, or blistering of the skin. An allergic reaction can become serious if left untreated, so make sure your doctor knows about any existing allergies to Lidocaine/Tetracaine or related medications.
Do not touch your face, eyes, or the affected area after the drug has been administered. You may accidentally hurt yourself while you are numbed.
