Promethazine is a commonly prescribed antihistamine drug used in the treatment of allergies and asthma.
Promethazine works by suppressing the central nervous system and has many other medical uses. Promethazine is typically used for nausea and vomiting caused by certain medical conditions (like post-operative nausea, or after/during certain surgery). It can also be used to treat allergic symptoms like runny nose, rash, and itching. Promethazine side effects include:
Promethazine overdose can cause death. Promethazine side effects are most common in people with underlying medical conditions, so if you’re not taking medications but have severe allergies or asthma, it’s important to seek medical attention immediately. Also, because the drug has side effects, people on promethazine usually take one or more other medications to treat their conditions. Because of this, the dosage of the drug can become irregular, so it can be hard to maintain a consistent dose. Promethazine side effects are the result of this unpredictability. If your symptoms continue after you’ve been taking promethazine, consult your doctor right away.
Promethazine side effects can also occur if you stop taking the drug. As mentioned earlier, the drug can have unpleasant side effects if you stop taking it.
One of the first symptoms to show up when you stop taking promethazine is headaches. This is because the drug decreases the amount of dopamine that is produced in the brain.
Another symptom of reduced dopamine is insomnia. With fewer amounts of dopamine in the brain, people may sleep more, or not at all. As long as there are still enough levels of dopamine in the brain to produce an adequate level of sleep, the problem should go away.
In some cases, you may notice that your vision may get worse while taking promethazine. This is because the drug is blocking the receptors that allow the brain to absorb the chemicals that cause blurry vision. This problem may last a few weeks. Once the receptors are blocked, your eyesight will return to normal.
Promethazine side effects can also occur if you have a heart attack. The drug stops a heart from beating. This can cause a heart attack in people who are already at risk of having heart problems. Because of this, you may experience chest pain, dizziness, or fainting spells while you’re taking promethazine.
When you stop taking promethazine, it can cause your urine to become darker than normal.
It’s because the drug stops a person’s body from producing a chemical that helps it process urine. In a few days, your urine will turn a light yellowish color.
Keep in mind that even if you think you’re safe on promethazine, you may still develop promethazine side effects. Talk to your doctor or pharmacist about taking a different type of medication or stopping your treatment.
A number of people have had bad results with promethazine. These include depression and psychosis. If you’re taking the drug, talk to your doctor about your concerns.
In most cases, the promethazine side effects you experience won’t cause you any problems. However, if they do, then talk to your doctor as soon as possible.
One of the most common side effects of promethazine is anxiety. It’s usually more serious in people who take the drug on a long-term basis. Other common side effects include stomach aches, nausea, vomiting, diarrhea, and drowsiness. If you’re experiencing one or more of these symptoms, you should talk to your doctor right away.
Remember that if you do experience any of these problems from promethazine, speak to your doctor right away. It can be very serious and you’ll need to get help as quickly as possible.
