Long-lasting relief

Excellent! This product works very well and offers great value. Initially, I used the regular tablets, which only lasted a few hours. These slow-release versions provide relief for up to 12 hours, reducing the need for more tablets. They contain guaifenesin, an expectorant that helps alleviate phlegm and sinus headaches. It's important to note these are not the DM version, which includes a cough suppressant. I avoided the DM variant due to potential interactions with other medications. I find these tablets comfortable to swallow and effective against sinus headaches.
