1. Why am I taking Mersyndol Forte?
Mersyndol Forte contains three active ingredients,
- paracetamol,
- codeine phosphate hemihydrate, and
- doxylamine succinate.
Paracetamol is an analgesic (pain-relieving medicine) and antipyretic (lowers body temperature). Codeine phosphate hemihydrate is a potent analgesic that helps to relieve pain. The body must convert codeine into morphine before it can provide pain relief. Doxylamine succinate is an antihistamine which can help to relieve tension and nausea associated with pain. This may be especially useful in the treatment of tension headache, migraine and period pain.
Mersyndol Forte is used for the short-term management of severe pain for which other treatment options have failed, are not recommended, not tolerated or are otherwise inappropriate to provide sufficient management of pain. This may include toothache and other dental pain, pain from injury or surgery, or headache pain.
