- hypersensitivity (severe allergic reaction). Tell your healthcare provider if you have an allergy to any other antibiotic, especially penicillin antibiotics (Pfizerpen, Pen VK, Amoxicillin, Augmentin, Zosyn, Unasyn, Timentin, Nallpen, Bicillin LA), before starting this medication. Tell your healthcare provider about any signs or symptoms of hypersensitivity, which include the following:
- chest pain
- swelling of the face, eyes, lips, tongue, arms, or legs
- difficulty breathing
- seizures. Tell your healthcare provider if you have ever had a seizure before starting this medication. Report any signs or symptoms of seizure activity, which can include the following:
- falling or fainting
- seeing bright lights or spots
- hearing sounds that are not there
- superinfection. Prolonged use can lead to the growth of dangerous organisms that are resistant or unresponsive to this medication. Take Merrem for the duration prescribed by your doctor.
- thrombocytopenia. This is a condition in which your blood has a lower than normal number of blood cell fragments called platelets. It is more likely to occur if you have kidney problems while taking Merrem. Tell your healthcare provider right away if you have the following signs and symptoms of thrombocytopenia:
- mild to serious bleeding
- purple, brown, and red bruises (purpura)
- small red or purple dots on your skin (petechiae)
- prolonged bleeding, even from minor cuts
- bleeding or oozing from the mouth or nose, especially nosebleeds or bleeding from brushing your teeth
- abnormal vaginal bleeding (especially heavy menstrual flow)
- blood in the urine or stool or bleeding from the rectum. Blood in the stool can appear as red blood or as a dark, tarry color. Taking iron supplements also can cause dark, tarry stools.
- headaches and other neurological symptoms. These problems are very rare, but you should discuss them with your doctor.
- diarrhea. Diarrhea is a common problem caused by antibiotics, and it usually ends when the antibacterial is stopped. Even after starting treatment with antibiotics, some patients can develop watery and bloody stools (with or without stomach cramps and fever) as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, contact your doctor, as this may be a sign of an infection of the bowels.
- Clostridium difficile (C. difficile) associated diarrhea. Some antibiotics can kill the “good” bacteria in the colon leading to a growth of C. difficile bacteria. This “bad” bacterium can cause diarrhea and other digestive problems, and these problems may even occur 2 months after the last dose. Extra caution for this side effect is advised in the elderly population. Tell your healthcare provider if you experience any or all of the following symptoms:
- watery diarrhea (at least three bowel movements per day for two or more days)
- loss of appetite
- abdominal pain or tenderness
Merrem can also cause headache and drowsiness. Do not drive or operate heavy machinery until you know how this medication affects you. Do not take Merrem if you are allergic to Merrem or any of its ingredients.
