Although it’s not a household name, Promethazin is a great medication that has many different uses. Promethazin is what is known as an antihistamine and anti-emetic drug. It blocks the effects caused by the naturally produced histamine in your body. It has many uses but it is mostly used to counter allergies like allergic rhinitis and hay fever. And when a person had symptoms of allergy like a runny nose, hives and skin rashes they are usually given Promethazin. Another common use for Promethazin is to combat motion sickness; travelers all over the world use this with great success. Dizziness and nausea after surgery are also treatable with Promethazin. In the past it was used as an anti-psychotic although it is hardly ever used for that purpose now.
It’s a prescription drug in the United States but in the United Kingdom and Switzerland it is available over the counter. Its brand names include Phenergan, Romergan, Prothiazine, Avomine, and Atosil. Because of its success and popularity there are many more brands that carry Promethazin.
Promethazin has negligible side effects. Dry mouth, dizziness, fatigue, constipation, and blurred vision are some side effects that affect users of this drug. Nothing extreme and nothing that lasts more that a few hours. More elderly users may encounter a bit of confusion when they take Promethazin. In extremely rare cases some seizures may occur, if this happens be sure to go to your doctor immediately.
When using Promethazin avoid drinking alcohol as it may make the side effects more severe. Also make sure you tell your doctor all the medications you are taking because they may interact badly with Promethazin, and don’t start taking new medication while on Promethazin without clearing it with your doctor first. Some medications that react badly with Promethazin are anxiety medications like Valium and Xanax, anti- depressants and narcotic pain medications. Also if you have liver conditions, seizure problems, high blood pressure, urination problems or glaucoma you should tell your doctor. Conditions like these affect the dosage of Promethazin given by your doctor.
Promethazin is also dangerous for pregnant women. Inform your doctor if you’re pregnant or if you plan to be so he can prescribe a different medication. And this drug also passes through a mother’s breast milk, so if you are on it it’s best to feed your child through the bottle.
Don’t forget that while taking Promethazin you should always follow the dose prescribed by your doctor. There’s no need to take this medication with food, just a tall glass of water.
