ARE TAGAMET AND PEPCID THE SAME THING?
Tagamet (cimetidine) and
Pepcid (
famotidine) are
histamine receptor antagonists used to treat and prevent certain types of
ulcer, to treat conditions that cause the
stomach to produce too much acid, and to treat
gastroesophageal reflux disease (
GERD).
Pepcid is also used to treat
Zollinger-Ellison syndrome.
Both Tagamet and Pepcid are available
over-the-counter (
OTC) and as generics.
Side effects of Tagamet and Pepcid that are similar include
headache,
dizziness,
joint or
muscle pain,
diarrhea,
nausea, or
constipation.
Side effects of Tagamet that are different from Pepcid include drowsiness,
depression, agitation,
breast swelling or tenderness (
in men), or
skin rash.
Side effects of Pepcid that are different from Tagamet include
fatigue, weakness, mood changes,
insomnia,
dry mouth, or vomiting.
Both Tagamet and Pepcid may interact with antacids or ketoconazole.
Tagamet may also interact with antidepressants or blood thinners.
Pepcid may also interact with
alcohol, atazanavir, itraconazole, cefditoren, dasatinib, delavirdine, fosamprenavir, or
aspirin or other nonsteroidal
anti-inflammatory drugs (
NSAIDs).
I don't know what they mean by "interact with" exactly. I see you shouldn't take NSAIDS such as ibuprofen with Pepcid. The generic of Pepcid is famitidone. I take famitidine and it is much stronger than Tagamet so I don't know why they don't recommend that instead.
