Since Stamlo Beta (which contains amlodipine and atenolol) is a prescription-only medication, he will need a consultation with a healthcare provider to get a new prescription for his 30-day supply. Even though he has taken this medication safely for four years, regular evaluations are important to monitor his blood pressure and ensure the treatment remains safe and effective. I recommend scheduling a quick in-person or telehealth appointment with his doctor, who can easily review his health and issue the refill prescription.
