Can I take Tripitor (atorvastatin) and Benadryl (diphenhydramine) together at night?
Tripitor is atorvastatin, a cholesterol medicine. Benadryl is diphenhydramine, an antihistamine used for allergy symptoms and sometimes for sleep. For most people, taking atorvastatin and diphenhydramine at the same time is usually not a direct “can’t-take-them-together” interaction. They work in different ways and are not known to have a common, serious drug-drug interaction.
That said, the practical issue is whether Benadryl is a good choice for you at night, not whether it can be combined with Tripitor.
What should I watch for when taking Benadryl at night?
Benadryl can cause drowsiness, dizziness, and slowed reaction time. It can also worsen confusion in older adults and may lead to next-day grogginess. If you have glaucoma, trouble urinating (such as prostate enlargement), certain breathing conditions (like COPD/asthma), or you fall frequently, Benadryl may be riskier.
If you plan to use Benadryl mainly to sleep, many clinicians prefer other options because diphenhydramine can cause more side effects than newer allergy/sleep approaches.
Does Benadryl affect cholesterol meds or sleep differently with Tripitor?
There’s no typical reason diphenhydramine would reduce Tripitor’s cholesterol effect, and Tripitor doesn’t usually change how Benadryl sedates you. The main concern is Benadryl’s sedation and side effects.
Could this be unsafe if I’m also taking other medicines?
The answer can change if you also take other sedating drugs, such as:
- alcohol
- opioids
- benzodiazepines (like lorazepam or alprazolam)
- sleep medications
- some anxiety or muscle-relaxing medicines
Combining sedatives can increase risks like extreme drowsiness, falls, and breathing problems.
Safer timing: should I separate them or take them together?
If you take both at night, taking them together is generally not a known interaction issue. Still, if Benadryl makes you very sleepy or dizzy, taking it at the time you go to bed (and being cautious about getting up during the night) is important. Follow your prescriber’s or pharmacist’s instructions for each medication.
When to get medical advice urgently
Seek urgent care or call emergency services if you have trouble breathing, swelling of the face/lips, severe confusion, fainting, or severe dizziness after taking Benadryl.
Quick questions so I can tailor the safest answer

2) How old are you?
3) Are you using Benadryl for allergies or for sleep?
4) Any other meds (especially pain meds, anxiety meds, or sleep meds) or alcohol tonight?
