Shake the suspension well before measuring a dose. To ensure that you get a correct dose, measure the liquid form of acyclovir with a special dose-measuring spoon or cup, not with a regular tablespoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one. Take all of the acyclovir that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated.
Store acyclovir at room temperature away from moisture and heat.
Take the missed dose as soon as you remember. However, if it is almost time for your next regularly scheduled dose, skip the missed dose and take the next one as directed. Do not take a double dose of this medication unless otherwise directed by your doctor. Seek emergency medical attention. Avoid letting infected areas come into contact with other people.
