For your acidity and indigestion, you can try an over-the-counter antacid or a proton pump inhibitor like Omeprazole (20 mg daily before breakfast) for short-term relief, alongside avoiding spicy foods. For early ejaculation, behavioural techniques (like the pause-squeeze method) or over-the-counter desensitising sprays can help. Prescription medications, such as Dapoxetine or certain daily SSRIs, are highly effective but require a clinical evaluation. Since some medications can interact or worsen stomach issues, please consult a healthcare professional or a urologist for a safe, personalised prescription plan.
