As for the negative sides of these medications, the list ofthose that are possible is rather long. However, the fact is that even thoughsome of them are really serious and might endanger the life of the patient, theyare not experienced frequently.
The doctors take into consideration the age of the patient, as well as presence of other conditions or medications that the patient is using,and the dosage is adjusted in order to prevent and avoid possible interactionsor negative effects. Still, even these measures of precaution are not alwaysenough to prevent some of them from occurring. Those that have been reportedmost frequently are pain in the stomach, constipation, drowsiness, nausea and headaches.It might also happen that the patient’s hands or feet will become swollen dueto the water retention, but none of these problems is a reason good enough tostop taking this medication before consulting a doctor. On the other side,medical help is necessary in cases a patient experiences pain in the chestarea, signs that indicate a heart attack, drop in the blood pressure, as wellas symptoms of paranoia, depression or temporary blindness. These problemsindicate that the patient definitely does not respond well to the medication,and its use needs to be stopped.
