Zacin 0.025% Cream

Zacin 0.025% Cream is a prescription-only topical medicine used for the symptomatic relief of osteoarthritis joint pain. Its active ingredient is capsaicin, a naturally occurring substance derived from chilli peppers.

Unlike oral painkillers that circulate through the entire body, Zacin is applied directly to the skin over the painful joint, allowing for targeted relief with a lower risk of systemic side effects like stomach irritation.

Capsaicin works through a unique process of "desensitisation." It targets a chemical in your body known as Substance P, which is responsible for transmitting pain signals from the peripheral joints to the brain.

• Initial Action: When first applied, capsaicin stimulates the release of Substance P, which may cause a temporary warm or burning sensation.
• Pain Relief: With regular use, capsaicin depletes the local stores of Substance P. Without this chemical, the nerves can no longer send strong pain signals to the brain, leading to a significant reduction in the sensation of arthritis pain.

To get the most benefit from Zacin, it must be applied consistently:

1. Pea-sized amount: Apply a small amount of cream to the affected joint (e.g., knee, hand, or hip).
2. Rub in well: Gently massage the cream into the skin until it is fully absorbed.
3. Frequency: Use the cream 3 to 4 times daily. Space doses by at least 4 hours.
4. Hand Hygiene: Wash your hands thoroughly with soap and cold water immediately after application. If you are treating your hands, wait 30 minutes before washing them.
5. Avoid Heat: Do not apply Zacin immediately before or after a hot bath or shower, as this can intensify the burning sensation.

Zacin is not an "instant" painkiller. Because it relies on depleting Substance P over time, it may take 1 to 2 weeks of regular application to notice a reduction in pain. It is important to continue using it as directed, even if you do not feel immediate relief.

The most common side effect is a warming, stinging, or burning sensation at the application site. This is a direct result of how the medicine works and usually diminishes after the first few days of regular use.

• Common: Redness, stinging, or a "heat" sensation.
• Inhalation: If you accidentally inhale the vapours (e.g., from your hands), it may cause coughing or sneezing.
• Serious: If you experience severe skin irritation or blistering, wash the area with cold soapy water and consult a healthcare professional.

Do not use Zacin 0.025% Cream if you:

• Are allergic to capsaicin or any of the other ingredients in the cream.
• Have broken, irritated, or inflamed skin on the area to be treated.
• Are under 18 years of age.

Speak to your prescriber before use if you are pregnant or breastfeeding.

Q: How long does Zacin take to work? Zacin is not an instant pain reliever. Because it works by gradually depleting the body's pain-signalling chemicals, it may take between 1 to 2 weeks of regular, three-times-daily application before you notice a significant reduction in pain.

Q: Why does the cream feel hot on my skin? The "heat" is caused by capsaicin stimulating the local nerve endings. This is normal. To manage this, avoid applying the cream to broken skin and stay away from hot baths or direct sunlight immediately after application.

Q: Can I use Zacin with other arthritis medications? Yes. Because Zacin is a topical treatment with very little absorption into the bloodstream, it can generally be used alongside oral anti-inflammatories like Naproxen or Ibuprofen. Always list all current medications during your online consultation.

Q: What should I do if I get the cream in my eyes? If accidental contact occurs, rinse the eyes immediately with plenty of cold water. If irritation persists, seek medical attention.
