Indications
Gravol Long Action Dual Relief is an over counter medication indicated for immediate and extended relief for nausea, vomiting, dizziness, and motion sickness.
Gravol contains dimenhydrinate, which is an antihistamine medication that works by blocking histamine receptors in the body. Histamine is a chemical that the body produces in response to allergies and motion sickness, and blocking its effects can help relieve symptoms such as nausea, vomiting, and dizziness.
The medication uses dual layer technology to provide both immediate and long-lasting relief, with the first layer providing fast-acting relief, and the second layer providing sustained relief for up to 12 hours. Overall, Gravol Long Action Dual Relief works by decreasing the effects of histamine on the body, which can help relieve symptoms associated with motion sickness and other conditions.
Use and Dosage
Gravol Long Action Dual Relief is a chewable tablet to take it by mouth usually with or without food every 4 to 6 hours, depending on the condition being treated. The chewable tablets should be chewed thoroughly before being swallowed.
The recommended dosage for adults is usually one caplet every 8-12 hours, up to a maximum of three caplets per 24 hours, as needed for relief of nausea, vomiting, and dizziness associated with motion sickness or other conditions. Do not take more than recommended or for longer than two weeks without medical supervision.
Use Gravol Long Action Dual Relief exactly as recommended by your doctor or pharmacist. If you are taking the tablet regularly and miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
