Capsaicin is a naturally occurring compound found in chili peppers and is known for its characteristic spicy or “hot” sensation. When used topically, capsaicin has been found to be useful in alleviating pain and inflammation, hence it is a commonly prescribed drug for conditions such as osteoarthritis, neuropathic pain, muscle strains, and post-herpetic neuralgia. Topical capsaicin comes in different preparations such as creams, gels, and patches. It is a non-invasive, targeted therapy for pain that can help patients avoid systemic side effects commonly seen with oral medications.
Capsaicin topical solutions are provided in a concentration of 0.025% to 0.075%. The recommended dosage and frequency of administration depend on the product preparation and the degree of the disease being treated.
Clean and Dry the Area: Apply topical capsaicin only when your skin is clean and absolutely dry.
Apply a Thin Layer: Place only a small amount of cream, gel, or a patch directly to the skin area that aches or hurts. Massage gently to have it absorbed by your skin.
Wash Hands Thoroughly: After application, it is very important to wash your hands properly to prevent accidental contact with your eyes or other sensitive areas. Capsaicin may cause irritation.
Repeat Application: Apply capsaicin several times a day as directed. This may be up to 4 times a day, depending on the product label and the severity of the condition.
It may take days to weeks of regular use before it can be felt that the application of capsaicin is creating its full effect, inasmuch as its pain-relieving effect takes time to gather pace with repeated applications.
Capsaicin is a naturally occurring chemical compound that acts as an analgesic when applied to the skin. The major way of acting for capsaicin is through desensitization of the pain receptors within the skin through depletion of a neurotransmitter called substance P. Substance P acts as a mediator for transmitting pain signals from peripheral nerves to the brain. The repeated application of capsaicin gradually decreases the quantity of substance P present in the nerve endings, and consequently, pain signals reduce in intensity.
Local application capsaicin is typically used for localized pain management. It is very effective to manage the following conditions, among others:
Osteoarthritis: Common arthritis characterized by the breakdown of cartilage in joints. This results in pain and stiffness.
Rheumatoid Arthritis: Autoimmune disorder causing inflammation in the joints.
It is offered in different concentrations between 0.025% to 0.075% and it is given in cream, gel, and patches forms.
Although capsaicin is generally well tolerated, side effects may occur in some users, especially during the initiation period of use when the skin is adapting to the medication.
Burning or Stinging Sensation: The most common side effect is a mild to moderate burning or stinging sensation at the application site. This is usually most pronounced during the first few days of use and usually subsides with time.
Redness or Irritation: Some people may develop redness, irritation, or slight swelling at the application site.
Dry Skin or Peeling: The application area may become dry or may peel off, especially if capsaicin is applied for a long time.
Severe Skin Reactions: Though rare, some people may develop severe skin reactions, including blistering, rash, or severe burning.
If the capsaicin medication is applied topically, here are some necessary precautions and contraindications
Avoid Contact with Eyes and Mucous Membranes: Capsaicin can cause severe irritation if it enters the eyes, nose, mouth, or mucous membranes. It is important to be sure to wash your hands well after applying the drug to avoid accidental contact of these areas.
Do Not Use on Open Wounds, Irritated Skin, Cuts: Capsaicin should not be used on open wounds, cuts, or highly irritated skin since it may enhance irritation or burning.
First Time Use Sensitivity: A low concentration of capsaicin (0.025% or 0.05%) is recommended for first time use to test skin sensitivity.
Gradually increase the concentration based on skin needs.
Pregnancy and Breastfeeding: There is scarce data on the safety of capsaicin in pregnancy or breastfeeding. It is recommended that pregnant or breastfeeding women consult a healthcare provider before using capsaicin.
Use in Children: Capsaicin should be used with caution in children. Always consult with a healthcare provider before using it in pediatric cases.
Capsaicin (topical), used for pain relief in conditions like arthritis, neuropathy, and muscle aches, can interact with other medications and substances, affecting its safety and effectiveness:
The proper dose of capsaicin would depend upon the severity of the condition treated, as well as the formulation to be used.
Cream and Gels: Capsaicin cream and gels are commonly applied 3 to 4 times daily to the affected area. It can start with a low concentration like 0.025% then increased to higher concentrations as tolerated.
Patches: Capsaicin patches, which are generally applied directly to the painful area, for localized pain such as in post-herpetic neuralgia, may be worn for up to 8 hours a day, depending on the product’s instructions.
Overuse or improper application can increase the risk of side effects, so it is essential to follow dosage instructions closely. Do not exceed the recommended daily dosage, as excessive use may lead to severe skin irritation or other adverse effects.
Topical capsaicin products, especially those with higher strengths (for example, 8% capsaicin patches), may need a prescription. However, over-the-counter preparations of lower-strength capsaicin creams are available, usually in the range of 0.025% to 0.075%. The availability of these products without a prescription will depend on the country or region.
It is always advisable to consult a healthcare provider before starting any new treatment to ensure the product is suitable for the condition being treated and to discuss potential interactions with other medications or health conditions.
Capsaicin topical is a medication derived from chili peppers, used to relieve pain by providing a warming sensation that distracts from the pain and by reducing the levels of substance P, a neurotransmitter involved in transmitting pain signals.
Capsaicin works by depleting and preventing the reaccumulation of substance P in peripheral sensory neurons, leading to decreased pain perception.
Capsaicin topical is primarily used to treat:
Capsaicin is applied directly to the skin in the affected area, usually in the form of a cream, gel, or patch. It is typically used several times a day.
Common side effects include:
Serious side effects are rare but may include:
Capsaicin should be avoided in individuals with:
Yes, Capsaicin can be used long-term, but it is recommended to consult a healthcare provider for regular assessment of its effectiveness and potential side effects.
Pregnant or breastfeeding women should consult their healthcare provider before using Capsaicin topical, as safety during pregnancy and lactation is not fully established.
Capsaicin topical should be stored at room temperature, away from heat and moisture, and kept out of reach of children.
If too much Capsaicin is applied, remove the excess with mild soap and water. If excessive irritation or burning occurs, consult a healthcare provider.
Capsaicin topical generally has fewer drug interactions, but always inform your healthcare provider of all medications and products you are using.
Capsaicin topical is usually applied 3 to 4 times daily, but follow the specific instructions provided with the product or by a healthcare provider.
If you miss a dose, apply it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose.
Capsaicin should not be applied to broken or irritated skin, as this may cause additional irritation or pain.
Capsaicin is primarily used for arthritis and neuropathic pain but may also help with other pain types; always consult a healthcare provider for recommendations.
Pain relief may occur within a few days of regular application, but it may take up to two weeks for optimal effects.
Capsaicin can be used with other pain medications; however, it’s best to consult with a healthcare provider for specific recommendations based on your medical history.
Capsaicin topical products are available over the counter at pharmacies, supermarkets, and online retailers.
