Contact your doctor immediately if you experience severe allergic reactions, such as difficulty breathing, swelling of your face, lips, tongue, or throat, or hives. These symptoms require urgent medical attention.
Seek medical advice if your symptoms worsen or don’t improve after 7 days of taking Aciclovir 400mg tablets, especially if you have a weakened immune system. This is particularly important for herpes infections.
If you develop new symptoms alongside your existing condition, consult your doctor. For example, new rashes, severe headaches, or changes in vision warrant a doctor’s assessment.
Discuss any existing medical conditions or medications you’re taking with your doctor before starting Aciclovir. This includes kidney problems, since Aciclovir is processed by the kidneys.
If you’re pregnant, breastfeeding, or planning a pregnancy, consult your doctor before using Aciclovir. They can advise on the safest course of action.
Children should only use Aciclovir under the strict guidance and prescription of a pediatrician or doctor. Never administer Aciclovir to a child without medical approval.
Report any unusual side effects, such as severe nausea, vomiting, or diarrhea, to your doctor. These could indicate a problem with your treatment.
