Zovirax Side Effects: What to Watch For

If you're using Zovirax, which has the active ingredient acyclovir, you're probably looking for clear facts about side effects. This medication is popular for treating viral infections like cold sores and shingles, but like anything, it can cause unwanted effects. Knowing what to expect can give you peace of mind and help you spot problems early.

Most people taking Zovirax experience mild side effects or none at all. Common mild reactions include headaches, nausea, and sometimes an upset stomach. These usually pass quickly and don’t require stopping the medication. Drinking plenty of water can help reduce stomach discomfort and support your body's process of clearing the drug.

When Side Effects Get Serious

Though rare, some serious side effects need immediate attention. Allergic reactions like rash, itching, swelling, or trouble breathing should send you to the doctor right away. Other red flags include unusual tiredness, confusion, dizziness, or changes in how often you urinate, which could signal kidney issues. If you notice symptoms like seizures or severe skin reactions, those are emergencies.

How to Minimize Risks

To keep side effects at bay, follow your doctor’s instructions carefully. Take Zovirax exactly as prescribed—don’t skip doses or stop suddenly unless advised. Stay hydrated, and mention any other medications or supplements you're taking, as some can interact with Zovirax. If you have kidney problems, your doctor may adjust your dose to lower risk.

Remember, not everyone reacts the same way. Some may feel perfectly fine, while others need close monitoring. Don’t hesitate to ask your healthcare provider about your concerns. With the right info and precautions, Zovirax can be effective and safe for managing your viral infection.
