Combining Lipitor and St. John's Wort: A Guide to Safe OTC Drug Use
When taking Lipitor (atorvastatin) and St. John's Wort (Hypericum perforatum) together, it's essential to be aware of potential interactions with over-the-counter (OTC) drugs. Lipitor is a prescription medication used to lower cholesterol levels, while St. John's Wort is a natural supplement commonly used to treat mild depression and anxiety. In this article, we'll explore the specific OTC drugs that should be avoided when taking Lipitor and St. John's Wort together.
Understanding the Risks of Interactions
Before we dive into the specific OTC drugs to avoid, it's crucial to understand the risks of interactions between Lipitor and St. John's Wort. St. John's Wort is a potent inducer of cytochrome P450 enzymes, which can increase the metabolism of certain medications, including Lipitor. This increased metabolism can lead to reduced efficacy and potentially dangerous side effects.
OTC Drugs to Avoid
When taking Lipitor and St. John's Wort together, it's essential to avoid the following OTC drugs:
Pain Relievers
* Acetaminophen (Tylenol): Taking acetaminophen with Lipitor and St. John's Wort can increase the risk of liver damage. Instead, opt for non-acetaminophen pain relievers like ibuprofen (Advil, Motrin) or naproxen (Aleve).
Cold and Allergy Medications
* Decongestants (Pseudoephedrine): Decongestants like pseudoephedrine can increase blood pressure and heart rate, which may be problematic when taking Lipitor. Look for decongestants without pseudoephedrine, such as phenylephrine (Sudafed PE) or oxymetazoline (Afrin).
Antihistamines
* Diphenhydramine (Benadryl): Diphenhydramine can increase the risk of drowsiness and confusion when taken with Lipitor and St. John's Wort. Instead, opt for antihistamines like loratadine (Claritin) or cetirizine (Zyrtec).
Antacids
* Magnesium and Aluminum Hydroxide (Maalox): Antacids containing magnesium and aluminum hydroxide can interact with Lipitor, reducing its effectiveness. Opt for antacids without these ingredients, such as calcium carbonate (Tums) or sodium bicarbonate (Alka-Seltzer).
Vitamin and Mineral Supplements
* Vitamin K: Taking vitamin K supplements with Lipitor and St. John's Wort can increase the risk of bleeding. Consult with your healthcare provider before taking vitamin K supplements.
Conclusion
Combining Lipitor and St. John's Wort requires careful consideration of potential interactions with OTC drugs. By avoiding the OTC drugs listed above and consulting with your healthcare provider, you can minimize the risk of adverse effects and ensure safe and effective treatment.
