H2 blockers (also sometimes referred to as acid reducers or H2 receptor antagonists) are available in nonprescription and prescription forms. Prescription forms are stronger than the nonprescription forms.
H2 blockers are usually taken by mouth, although some can also be given as an injection. Two doses (morning and evening) are generally recommended to control both daytime and nighttime symptoms. Doctors sometimes recommend a single dose, taken at bedtime, for people who have difficulty remembering to take their medicines.
