Contact your doctor immediately if your cold sores worsen despite using Zovirax cream. This includes increased pain, swelling, or spreading of the sores beyond the initial area.
Signs Requiring Immediate Medical Attention
- Fever exceeding 101°F (38.3°C). Swollen lymph nodes near the affected area. Development of a new sore, particularly if it’s significantly different from previous outbreaks. Signs of a secondary bacterial infection like increased pus or redness. Cold sores lasting longer than two weeks. Severe pain or discomfort that interferes with eating or drinking.
If you experience any of these symptoms, seek medical attention promptly. Early intervention can prevent complications.
When to Schedule a Follow-Up Appointment
Schedule a check-up with your doctor if:
Cold sores recur frequently, more than six times a year. You are pregnant, breastfeeding, or have a weakened immune system. Zovirax cream is not improving your symptoms after a week of consistent use, following the prescribed instructions. You have concerns about the application or side effects of the cream.
Remember, these guidelines serve as a general recommendation. Individual needs vary; consult your healthcare provider for personalized advice.
