Acivir dosage: what you need to know

If you’ve been prescribed Acivir, the most important thing is getting the dose right. Too little won’t work, too much can cause side effects. Below we break down the basic dosing rules, how to adjust for weight or kidney issues, and practical tips to stay safe.

How to calculate your Acivir dose

Acivir is usually given based on body weight. The standard recommendation is 10 mg per kilogram of body weight per day, divided into two doses. Here’s a quick way to figure it out:

• Step 1: Weigh yourself in kilograms. If you only know pounds, divide the number by 2.2.
• Step 2: Multiply that weight by 10 mg.
• Step 3: Split the total into two equal parts for morning and evening.

Example: You weigh 70 kg (about 154 lb). 70 kg × 10 mg = 700 mg total daily dose. Take 350 mg in the morning and 350 mg at night.

If your doctor gave you a different strength (e.g., 250 mg tablets), just round to the nearest whole tablet. Always double‑check the math before you start.

Tips for safe use

Even with the right calculation, a few practical steps keep you on the safe side:

• Take with food. A light meal helps your stomach absorb Acivir without irritation.
• Stay hydrated. Drinking a glass of water with each dose reduces the chance of constipation.
• Watch for side effects. Common issues are mild nausea, headache, or dizziness. If they get worse, call your doctor.
• Adjust for kidney problems. If you have reduced kidney function, your doctor may cut the dose by 30‑50 %.
• Don’t skip doses. Missing a dose can cause the infection to bounce back. If you forget, take it as soon as you remember, unless it’s almost time for the next dose.

Finally, keep a short notebook or use a phone reminder to track each dose. That simple habit can prevent accidental double‑dosing and give you peace of mind.

Remember, the numbers above are general guidelines. Your prescriber knows your medical history and may have tweaked the dose for you. Always follow their specific instructions and ask questions if anything feels unclear.

With the right dose and a few easy habits, Acivir can work effectively while keeping side effects at bay. Stay informed, stay consistent, and you’ll get the best results from your treatment.
