After taking Tenoha-M 1000 mg, the sponge-like or tablet-shaped material seen in the vomit is most likely the outer shell or undissolved part of the tablet. This medicine is available in a prolonged-release form, which means it slowly releases the medicine in the body over several hours. After the active medicine is absorbed, the empty tablet shell may remain and can sometimes appear in the vomit or stool. This may look like a soft sponge, a gel-like mass, or even a partly intact tablet. In many cases, this is normal and does not mean the medicine has failed to work. However, if vomiting occurs soon after taking the tablet, the body may not have absorbed the full dose. Occasional vomiting may also occur due to stomach irritation, especially if the medicine is taken on an empty stomach. Take the tablet after food and swallow it whole without crushing or chewing. If vomiting happens repeatedly, blood sugar becomes uncontrolled, or you frequently notice whole tablets coming out, please consult your doctor for further advice.
