Yes, Olmetec® (olmesartan) can cause cough but it sounds like you are being treated for a respiratory infection with an antibiotic and additional medicines to thin your mucus.  If that is so, cough can sometimes last for weeks after an infection and, if a person has asthma, cough can last for months after an infection.  You should consider trying a cough suppressant medicine, one that contains either codeine or dextromethorphan.  If you have asthma, this might be a good time to increase an inhaled steroid, if you are on this medicine, or ask your doctor for a prescription for one of the common inhaled steroids, for example, Flovent® HFA Inhalation Aerosol (fluticasone propionate).

Good luck.
