Patients with bronchial asthma, those using it on inflamed areas with infections, chronic degenerative arthritis patients, pregnant women, nursing mothers, and the elderly should consult with a doctor or pharmacist before use.

Nursing mothers are advised against using this medication as it may be transmitted through breast milk. The elderly are advised to use this drug cautiously as they may be at higher risk of cardiovascular, gastrointestinal, and kidney-related side effects. If severe skin adverse reactions such as red spots, rashes, swelling, blisters, itching, pain, etc. occur, discontinue use immediately and consult a healthcare professional. Rarely, severe allergic reactions like hypersensitivity, angioedema, or asthma attacks may occur, so caution is warranted. This medication is symptomatic relief and should be used along with methods to treat the underlying cause. If used for more than two weeks, reevaluation of therapeutic effects and side effects should be undertaken. Do not apply to the eyes or mucous membranes, and avoid use on damaged or inflamed skin. Refrain from using occlusive dressing, and be cautious as temporary irritation or tingling may occur at sites of skin damage.

Overuse may lead to systemic side effects such as hypotension, renal failure, seizures, gastrointestinal discomfort, and respiratory depression, and appropriate treatment is required in such cases. This drug can affect kidney function, so renal status should be closely monitored when used with diuretics. There is a risk of serious gastrointestinal side effects, such as gastrointestinal bleeding, ulcers, and perforations, particularly when used with anticoagulants like warfarin, as the bleeding risk may increase, so caution is advised.
