Dear Customer, Thanks for providing quick additional information.
I can understand your concern.
Well, most likely you are experiencing side effects from Acyclovir. Having Black, tarry stools after finishing course of Acyclovir has been found in some persons.
Having heartburn, nausea are also side effects of this medication.
A black stool caused by food, supplements, medication, or minerals is known as "false melena".
This can also occur due to blood coming from the upper part of the gastrointestinal (GI) tract. It can occur with gastric ulcers or gastritis and /or GERD(gastro esophageal reflux disease).
As you have any other rleated symptoms, so most likely it is due to side effect of Acyclovir and would disappear by its own.
A clinical evaluation is necessary for precise diagnosis.
Please get it clinically evaluated from your doctor.
Good luck and Take care.
Please let me know how I can be of further assistance.
