How should I take guanidine (Guanidine HCl)?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor.

Your doctor may occasionally change your dose to make sure you get the best results from this medication.

Guanidine can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. Your urine may also need to be tested. It is important that you not miss any scheduled visits to your doctor.

Store guanidine at room temperature away from moisture and heat.
