Looking for a minocycline HCl ER coupon? Minocycline hydrochloride extended-release is the generic version of Solodyn, a once-daily oral antibiotic FDA-approved to treat the inflammatory pimples and bumps of moderate to severe acne in people 12 and older. Because a generic is available, it is already an affordable option, but the cash price can vary a lot from one pharmacy to the next. Enter your ZIP above to see today's price, and Rx.com compares more than 60,000 pharmacies so you can find the lowest cost near you.
What is minocycline HCl ER and how does it work?
Minocycline hydrochloride extended-release (ER) is a tetracycline-class antibiotic in a once-daily, extended-release oral tablet. It is the generic equivalent of the brand Solodyn. It is FDA-approved to treat the inflammatory lesions (the red pimples and bumps) of non-nodular moderate to severe acne vulgaris in patients 12 years and older. The dose is weight-based (about 1 mg per kilogram) and it is taken once a day.
It is important to know that this extended-release acne formulation is not the same as regular (immediate-release) minocycline. The ER form has only been studied for up to 12 weeks and is not indicated for treating infections. Immediate-release minocycline is used more broadly for bacterial infections. Always take this medication exactly as your provider directs.
Minocycline HCl ER cost and savings without insurance
Because minocycline HCl ER is available as a generic, it is generally one of the more budget-friendly acne prescriptions, and it is usually much cheaper than paying cash for brand-name Solodyn. Even so, the cash price without insurance can differ widely between pharmacies, which is exactly why comparing before you fill matters.
Rx.com compares prices across more than 60,000 pharmacies so you can spot the lowest price in your area. Enter your ZIP above to see today's price, then bring the coupon to the pharmacy counter. There is no membership fee to compare, and the discount can be used whether or not you have insurance.
Alternatives and related medications
Minocycline is one of several tetracycline-class antibiotics used for acne. If you and your provider are weighing options, related medications include:
- Solodyn — the brand-name version of minocycline ER
- Minocycline — the immediate-release form
- Doxycycline and Doxycycline hyclate — another commonly used tetracycline-class option
- Tetracycline
Which medication is right for you depends on your acne, your history, and your provider's judgment. This is not medical advice, so talk with your provider or pharmacist before switching. You can compare cash prices on any of these on Rx.com by entering your ZIP.
Important safety information
Do not use minocycline HCl ER during pregnancy. Tetracyclines can cause permanent tooth discoloration and can slow bone growth in a developing baby. It should also not be used in children under 8 because it can permanently stain the teeth a yellow-gray-brown color. It should not be used by anyone who is allergic to tetracycline-class drugs, and it is not intended for treating infections.
More serious but less common risks include severe allergic and hypersensitivity reactions (including DRESS), a drug-induced lupus-like syndrome, autoimmune hepatitis, serum-sickness-like reactions, and increased pressure around the brain (pseudotumor cerebri). It can also cause sun sensitivity and sunburn, dizziness or lightheadedness, and, with long-term use, permanent darkening of the skin, teeth, or gums. It may make birth control pills less effective, and rarely causes serious diarrhea (C. difficile). This is not a complete list. Talk with your provider or pharmacist about your full medical history and any side effects you notice.
