Promethazine

Promethazine is an antihistamine medication with a sedating effect, making it helpful for promoting sleep.

Antihistamines block histamines from attaching to receptors in the body. This prevents them from causing allergy symptoms, such as a runny nose, itchy eyes, and sneezing. However, antihistamines can also block histamines from attaching to receptors in the brain. As the chemical is involved in regulating sleep and wakefulness, this action causes drowsiness and aids restful sleep.

Promethazine can cause a number of side effects, including drowsiness, dizziness, dry mouth, blurred vision, and constipation. In rare cases, it can also cause more serious side effects, such as seizures, heart problems, and liver damage.

Promethazine should be used cautiously. It’s typically prescribed for short-term use and in limited supply. It should be taken as needed, rather than daily, to help reduce any risk of psychological dependence on promethazine.

Promethazine is available in tablet form with strengths of 10mg, 20mg, and 25mg. The dose depends on the condition it is being used to treat. For short-term insomnia, a dose of 25mg to 50mg at night is typically recommended.

Promethazine should only be taken as prescribed. The recommended adult dose for promethazine to aid sleep is 25 to 50 milligrams taken orally at bedtime.

Follow these guidelines:

• Take the medication exactly as prescribed.

• Do not exceed the recommended dosage.

• Take promethazine shortly before bedtime to maximise its effects.

• Swallow tablets whole with water.

• Avoid alcohol and any other drugs with sedative properties while using promethazine.

• Use promethazine for sleep when necessary and prescribed. Short-term use is recommended.
