Why you must avoid medication for migraine, cold and birth-control pills before vaccination

In a Facebook post on Sunday, Thiravat said: “Severe reactions are rare but it is best to reduce the chance of occurrence to as low as possible.”

“One of the severe reactions to Covid-19 is constant inflammation that could result in vasoconstriction, or the narrowing of blood vessels and occurrence of a blood clot. Therefore, recipients should refrain from taking drugs that already cause vasoconstriction, such as medicines for migraine and cold,” he said.

“As for patients who are on cannabis oil or CBD oil, such as the Deja Formula Ganja Oil produced by Department of Thai Traditional and Alternative Medicine which helps reduce inflammation, they can continue taking the drug before vaccination without increasing the dosage,” he added.

Thiravat added that women who use female hormones for birth control or treating of other diseases should stop taking the pill at least 14 days before vaccination.

“These recommendations are also applicable to other vaccines,” he said.

Data from the Department of Disease Control revealed that from April 28 to May 28, over 3.5 million doses of Covid-19 vaccine have been administered in Thailand. About 2.41 million got the first jab and 1.09 million have received both jabs.
