Take Levoxyl exactly as it was prescribed for you. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Levoxyl is taken by mouth.
Levoxyl works best if you take it on an empty stomach, 30 to 60 minutes before breakfast. Follow your doctor's dosing instructions and try to take the medicine at the same time each day.
Swallow the tablet whole, with a full glass (8 ounces) of water. The Levoxyl tablet may dissolve very quickly and could swell in your throat.
When giving Levoxyl to infants and children who cannot swallow tablets the tablets may be crushed. Place the freshly crushed tablet in a small amount (5 mL to 10 mL or 1 to 2 teaspoonfuls) of water and immediately give the medicine by spoon or dropper. Do not store the mixed medicine or mix it with foods that decrease the absorption of levothyroxine, such as soybean-based infant formula.
It may take several weeks before your body starts to respond to levothyroxine. Keep using Levoxyl even if you feel well. You may need to use for the rest of your life.
You may need frequent medical tests. Tell any doctor, dentist, or surgeon who treats you that you are using .
Store at room temperature away from moisture and heat.
Do not share Levoxyl with another person, even if they have the same symptoms you have.
