Before taking any medication, including those identified as CPC 835, it is important to understand its properties and potential effects. This information is for general knowledge and should not be considered medical advice. Always consult with a healthcare professional before starting any new medication.
Identifying the CPC 835 Pill
If you find an unfamiliar pill, using its unique imprints can help identify it accurately. The pill with the markings 'CPC 835' is specifically a Diphenhydramine Hydrochloride capsule. The pill is described as a pink and white, capsule-shaped, oblong pill. Diphenhydramine is the active ingredient in several well-known brand-name and generic medications, most notably Benadryl. It is a first-generation antihistamine widely available without a prescription and is not a controlled substance. However, it is crucial to understand its pharmacological effects, uses, and potential side effects before taking it.
What is Diphenhydramine?
Diphenhydramine is an antihistamine that works by blocking the action of histamine, a substance the body releases during an allergic reaction. Histamine causes symptoms such as sneezing, itching, watery eyes, and a runny nose. As a first-generation antihistamine, diphenhydramine is known for its strong sedative properties, meaning it causes significant drowsiness. This sedative effect is why it is also commonly used as a short-term sleep aid. The medication can be taken orally in various forms, including capsules, tablets, and liquids.
Uses of CPC 835 (Diphenhydramine)
Diphenhydramine has several clinical applications due to its antihistamine and sedative effects. The primary uses for the CPC 835 pill include:
- Allergy Relief: It effectively relieves symptoms associated with hay fever and other upper respiratory allergies, such as sneezing, runny nose, itchy throat, and watery, itchy eyes.
- Cold Symptoms: It can help alleviate common cold symptoms, particularly sneezing and a runny nose.
- Insomnia: Due to its sedative properties, it is frequently used as a short-term aid for difficulty falling or staying asleep.
- Motion Sickness: Diphenhydramine can be used to help prevent and treat symptoms of motion sickness.
Potential Side Effects
Like all medications, diphenhydramine can cause side effects. These can range from common and mild to more severe reactions.
Common Side Effects:
- Drowsiness and Dizziness: This is one of the most prominent side effects and a key reason for its use as a sleep aid.
- Dry Mouth, Nose, and Throat: These symptoms are common due to the medication's anticholinergic effects.
- Blurred Vision: Some users may experience temporary blurred vision.
- Upset Stomach: Constipation or other digestive issues may occur.
- Excitability: While it typically causes drowsiness, children may experience the opposite effect, becoming excitable.
Serious Side Effects:
- Vision problems: Seek immediate medical attention for significant vision changes.
- Difficulty urinating: Painful or difficult urination can be a serious side effect.
- Confusion or severe drowsiness: Excessive sedation or mental confusion warrants medical consultation.
- Seizures: Though rare, convulsions have been reported.
Important Safety Information and Warnings
Before taking any medication, especially an over-the-counter one, it is important to be aware of the safety precautions. The FDA has issued warnings regarding high doses of diphenhydramine due to the risk of serious side effects.
- Avoid Alcohol: Combining diphenhydramine with alcohol or other sedatives can significantly increase drowsiness and impair cognitive function.
- Driving and Operating Machinery: Given its sedative effects, patients should not drive or operate heavy machinery until they know how the medication affects them.
- Age Restrictions: Diphenhydramine is not recommended for children under 2 years old, and use in children between 2 and 5 should only be done under a doctor's guidance. Older adults (65 and older) are more susceptible to side effects like dizziness and confusion and should use this medication with caution.
- Pre-existing Conditions: Individuals with certain health issues should consult a doctor before use. These include breathing problems like emphysema or chronic bronchitis, glaucoma, or an enlarged prostate.
- Short-Term Use: The medication should only be used for short-term relief, typically no more than two weeks for insomnia. Long-term use can increase the risk of memory problems and confusion.
- Avoiding Overdose: Many OTC products contain diphenhydramine. Always check labels to avoid taking more than one product with the same active ingredient, as this can lead to an overdose.
Comparison: Diphenhydramine vs. Other Antihistamines
When choosing an antihistamine, comparing first-generation options like diphenhydramine with second-generation alternatives can be helpful. The primary difference lies in their sedative effects.
