Fastac Fast Acting Pain Killer is a topical analgesic formulated to provide rapid relief from muscular and joint pain. It contains Diclofenac (1.16% w/w), a non-steroidal anti-inflammatory drug (NSAID) known for its effectiveness in reducing inflammation and alleviating pain. The inclusion of Linseed Oil (3% w/w) helps to soothe and nourish the skin while enhancing the absorption of active ingredients. Menthol (5% w/w) provides a cooling sensation that helps to distract from pain and reduce discomfort, promoting a feeling of relief upon application. Methyl Salicylate (10% w/w), commonly known as wintergreen oil, acts as a counterirritant, increasing blood flow to the affected area and further easing stiffness and soreness. Fastac Fast Acting Pain Killer is ideal for use in conditions such as arthritis, sprains, strains, backache, and sports injuries. It is designed for external use only and should be applied gently to the affected area, avoiding broken or irritated skin. With its synergistic blend of ingredients, Fastac offers quick, targeted relief, helping users regain mobility and comfort without the need for oral painkillers. Always follow the recommended dosage and consult a healthcare professional if symptoms persist.
