Precautions

This medication should not be used by individuals with allergic reactions or hypersensitivity to any of its components. Additionally, it is recommended that patients taking certain antiviral agents or those who are pregnant or breastfeeding refrain from using this medication. Patients with liver or kidney dysfunction, as well as the elderly, should use this drug with caution. During treatment, various side effects such as heartburn, diarrhea, headache, and dizziness may occur, and if any unusual symptoms arise, immediate consultation with a physician is advised. Long-term use may increase the risk of vitamin B12 deficiency or osteoporosis-related fractures, so regular check-ups are necessary. Furthermore, this medication suppresses gastric acid, which may promote bacterial growth in the stomach, thereby potentially increasing the risk of infections such as enteritis or diarrhea. When taken with other medications, interactions may occur, so it is essential to consult a doctor or pharmacist. Pregnant women should avoid this medication due to potential effects on the fetus, and breastfeeding women should discontinue breastfeeding while taking this drug. Safety in children and adolescents has not yet been established, so use in this age group is not recommended. Caution is required when driving or operating machinery during use, as side effects may impair concentration. The medication should be stored in a safe place out of reach of children, and it is advisable not to transfer it to other containers.
