hi throbbing is an inherent part of migraines i know as a dr and also as a migrainee myself well u are taking losartan so u probably have hypertension as well next time you have a headache have your bp checked high blood pressure in itself is a cause of headache sometimes with throbbing nature second if the frequency of headache increases we can always start prophylactic medications like sibellium 10 once at bedtime third u r taking maxide its a medicine usually prescribed for tension and stress headaches so i would suggest relaxation techniques like meditation and yoga fourth meet your local physician you are taking losartan better drug are now available in the same group like telmisartan and olmesartan an equivalent dose would probably be 40 mg and 20 mg respectively best of luck
