What is the dosage and how should it be used?
Ranitidine comes as a tablet, an effervescent tablet, effervescent granules, and a syrup to be taken by mouth.
Take ranitidine exactly as your doctor has prescribed it for you. Do not use more of the medication than recommended nor longer than prescribed.
Take each ranitidine tablet with a full glass of water.
The ranitidine effervescent tablet or granules must be dissolved in water before taking each dose. Tablets or granules should not be chewed, swallowed whole, or dissolved on the tongue.
Place the Zantac 150 mg Efferdose tablet in a full glass (6 to 8 ounces) of water. Allow the tablet to completely dissolve, then drink the entire mixture.
Place the Zantac 25 mg Efferdose tablet in at least 1 teaspoon of water. Allow the tablet to completely dissolve, then drink the entire mixture. If you are giving this medicine to a child, you can place this mixture in a medicine dropper or syringe before giving it to the child.
Ranitidine granules should be mixed with 6 to 8 ounces of water before drinking.
To be sure you get the correct dose, measure the liquid form of ranitidine with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one. Ranitidine syrup may be given to an infant or child by medicine dropper or oral syringe.
Do not stop taking ranitidine without asking your doctor. It may take up to 8 weeks for an ulcer to heal.
