Safety measures for antihistamine as sleep aid

Please make sure that you educate yourself before taking prescription sleep aid like antihistamine. Its side effects if possible and the interactions with the other drugs you are taking. Start in small doses and increase gradually as what your doctor prescribes you. Monitor your body's reaction and any side effects that you may encounter. Try not to take it every day but rather irregularly to increase its effectiveness and decrease its side effects. Last, it is always important to consult your doctor first and ask for his advice.
