We consider the effect of a doubly charged Higgs boson ({Delta}{sup {minus}{minus}}) on several processes. We find that the effective Hamiltonian that is normally used to interpret the results of muonium-antimuonium oscillation experiments also describes the {ital t}-channel exchange of a {Delta}{sup {minus}{minus}}. A limit on the existence of the {Delta}{sup {minus}{minus}} is extracted from the most recent muonium oscillation result. The effect of {Delta}{sup {minus}{minus}} exchange on high-energy Bhabha scattering is discussed, and a limit is extracted from the published cross sections of several experiments at the SLAC and DESY storage rings PEP and PETRA. The case of a nondiagonal coupling of the {Delta}{sup {minus}{minus}} to the charged leptons (nondiagonal in lepton flavor) is considered. A limit is extracted from the result of the most recent search for the rare decay {mu}{r arrow}3{ital e}. Finally, a coupling-independent limit is extracted from a recent measurement of the process {ital e}{sup +}e{sup {minus}}{r arrow}4 leptons at PETRA.
