Promethazine Hydrochloride Tablet (Generic)

What is Promethazine Hydrochloride Tablet (Generic)

What it does

• Blocks histamine to calm allergy symptoms like sneezing, hives, and itching.
• Acts as an antiemetic to help settle the stomach and reduce motion sickness.
• Has a sedating effect that can support rest when symptoms keep you up at night.

What to expect

• Many people notice drowsiness. That is normal with first-generation antihistamines.
• Relief of nausea and motion sickness tends to feel like a settling of the stomach and less dizziness.
• For allergies, you may notice fewer sneezes, less runny nose, and reduced itching.
• Avoid driving or operating machinery until you know how you respond. Some folks feel more slowed or groggy than others.

Who should not use it?

• Do not give to children under 2 years old due to severe breathing risks.
• Older adults can be more sensitive to confusion, dry mouth, constipation, and falls. Ask your prescriber if a lower dose or a different option makes sense.
• Talk to your provider first if you have asthma, COPD, sleep apnea, glaucoma, trouble urinating due to an enlarged prostate, bowel blockage, liver problems, or seizure disorders.

Important safety notes

• Combining with other medicines that make you sleepy can be risky. That includes opioids, benzodiazepines, sleep medicines, some muscle relaxers, and alcohol. The combo can slow breathing.
• This is an antihistamine from the phenothiazine family. It can cause dry mouth, blurred vision, constipation, dizziness, and thickened mucus. Stand up slowly to avoid lightheadedness.
• Not everyone should use it for sleep. If insomnia is the main issue, ask your clinician about safer long-term options.
• If you feel unusually short of breath, very confused, extremely drowsy, or develop a rash or swelling, get medical help.

How to use it wisely

• Take exactly as prescribed. Do not take extra for faster relief.
• For motion sickness, your clinician may advise taking it before travel. Follow the timing they give you.
• Avoid alcohol. It can significantly increase drowsiness and slow your reaction time.
• If you are pregnant, planning to become pregnant, or breastfeeding, ask your healthcare professional about the pros and cons for your situation.
