Restoril with antacids and acid blockers
Antacids and acid-blocking medications (PPIs like omeprazole, H2 blockers like ranitidine or famotidine) are widely used and can subtly affect the absorption of medications taken alongside them. For Restoril (Temazepam) at 7.5mg, 15mg, 22.5mg, 30mg, the impact depends on how Temazepam is absorbed and whether gastric pH plays a role.
How antacids affect Restoril
Antacids work locally to neutralise gastric acid; PPIs and H2 blockers reduce acid secretion over hours. Some medications need an acidic stomach for proper dissolution and absorption — for these, co-administration with PPIs reduces effective dose. Other medications absorb fine regardless of pH. Whether Temazepam is pH-sensitive is in the prescribing information. Temazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance.
Practical guidance
According to general pharmacy practice, separating antacid doses from Restoril by 2 hours avoids most direct binding interactions. PPIs and H2 blockers, taken on their own schedule, do not need timing separation but can shift Temazepam absorption over weeks of co-use. The pharmacist confirms whether Restoril at 7.5mg, 15mg, 22.5mg, 30mg is affected.
Frequently asked questions
Can I take antacids with Restoril? ▾
Yes for most users, but separating the doses by 2 hours minimises any direct interaction with Temazepam at 7.5mg, 15mg, 22.5mg, 30mg. Some medications bind to antacid components and absorb less effectively if taken simultaneously.
Will my PPI affect Restoril? ▾
For most Sleep Aids and Hypnotics medications, no clinically meaningful interaction. For pH-sensitive active ingredients, chronic PPI use can reduce absorption of Restoril; the prescriber may consider an alternative or a dose adjustment if this applies to Temazepam.
