Individuals currently taking MAO inhibitors or who have discontinued them within the last 2 weeks, including antidepressants, antipsychotics, mood stabilizers, and anti-Parkinson agents, should consult a doctor before using this medication. Those with a history of allergies or who have previously experienced allergic reactions to medications should seek professional advice before using this medication. It is important for individuals with high blood pressure, heart disease, diabetes, thyroid disease, or glaucoma to consult a doctor before use. Pregnant women or those who may become pregnant should consult healthcare providers before using this medication. Smokers or those with respiratory conditions such as asthma, chronic bronchitis, emphysema, or prolonged cough lasting more than a week should definitely consult a doctor before use. This medication contains an ingredient called propylene glycol, which requires caution for those with allergies. If symptoms such as rash, redness, swelling, irritation, or itching occur during use, discontinue use immediately and consult a healthcare provider. If symptoms do not improve after 3 days of use, consult a professional. Always follow the prescribed dosage and administration guidelines without fail, as excessive use can worsen nasal congestion. This medication is for nasal use only and should not be used in the eyes or ears. To prevent contamination, it is advisable to avoid shared use. Do not use for more than 7 days, and as it may cause drowsiness, caution should be taken when driving or operating machinery. It is safe to avoid alcohol while using this medication. When used in children, supervision by an adult is necessary. Due to the presence of benzalkonium chloride, which can cause bronchospasm or nasal mucosal irritation, caution is advised with long-term use. Keep this medication out of reach of children and store in a cool, dry place away from direct sunlight. To maintain quality, it is crucial not to transfer it to another container.
