How To Take
Take Famvir exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Taking more of this medication will not make it more effective. Treatment with Famvir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters). You may take Famvir with or without food. Take this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. To prevent recurrent genital herpes, you may need to take this medicine twice daily for up to 1 year. Follow your doctor's instructions. Lesions caused by herpes viruses should be kept as clean and dry as possible. Wearing loose clothing may help to prevent irritation of the lesions. Store Famvir at room temperature away from moisture and heat.
Get emergency medical help if you have any of these signs of an allergic reaction to Famvir: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
