Taking 800 mg of acyclovir can cause various side effects, although not everyone experiences them. The severity and frequency vary depending on individual factors like overall health and other medications taken.
Common Side Effects
- Headache: A relatively frequent side effect. Staying hydrated and using over-the-counter pain relievers, as directed, can often help manage this. Nausea and Vomiting: These are also common. Taking acyclovir with food can sometimes lessen these symptoms. If vomiting is severe or persistent, consult your doctor. Diarrhea: Drink plenty of fluids to prevent dehydration. Fatigue: Rest is crucial. Avoid strenuous activity until you feel better.
Less Common but Serious Side Effects
While less common, some side effects require immediate medical attention:
Severe allergic reactions: These can manifest as skin rash, difficulty breathing, or swelling of the face, lips, or tongue. Seek immediate medical help if you experience any of these. Kidney problems: Acyclovir can, in rare cases, affect kidney function, especially in individuals with pre-existing kidney issues or those taking other nephrotoxic drugs. Your doctor should monitor your kidney function if you have such risk factors. Neurological effects: These are uncommon but can include confusion, tremors, seizures, or hallucinations. If you notice any unusual neurological changes, contact your physician immediately.
Medication Interactions
Acyclovir can interact with certain medications. Always inform your doctor of all medications, supplements, and herbal remedies you are taking.
When to Contact Your Doctor
Contact your doctor if any side effects are severe, persistent, or worsen. Don’t hesitate to reach out with concerns, even if they seem minor.
