Merlin is certainly available for adults, for example, when used for fever or pain relief, generally 15-20mL per dose, equivalent to 300-400mg of ibuprofen per dose, 3-4 times/day. If used to reduce fever or relieve pain, take it every 6-8 hours and do not take too much. This is because ibuprofen overdose has significant irritating effects on the gastrointestinal tract, like nausea and vomiting, and can even lead to ulcers and bleeding in the gastrointestinal tract. Merlin is a trade name for ibuprofen suspension, which generally contains 20mg of ibuprofen per 1mL of ibuprofen suspension. merlin is mainly used for fever caused by common cold or influenza, but also for relief of mild to moderate pain, such as headache, joint pain, migraine, toothache, muscle pain, nerve pain, etc. Because children often have difficulty swallowing tablets or capsules, they are made into ibuprofen suspension. Ibuprofen suspension is used preferentially in children, but of course it is also available for adults.
