Solodyn Overview - Patient Information: Side Effects
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: sunburn (sun sensitivity), muscle pain, difficult/painful swallowing, change in the amount of urine, pink urine, brown/gray tooth discoloration, blue/gray/brown discoloration of the skin/lips/tongue/gums, numbness/tingling of the hands/feet, unusual tiredness, stopping of menstrual periods, new signs of infection (e.g., fever, chills, persistent sore throat).
Tell your doctor immediately if any of these rare but very serious side effects occur: hearing changes (e.g., ringing in the ears, decreased hearing), easy bruising/bleeding.
Tetracycline drugs such as minocycline may rarely cause a serious increase in pressure inside the skull (intracranial hypertension-IH). The risk of this side effect is greater for women of childbearing age who are overweight or who have had IH in the past. If IH develops, it usually goes away after minocycline is stopped; however, there is a chance of permanent vision loss or blindness. Get medical help right away if you have: persistent/severe headache, vision changes (such as blurred/double vision, decreased vision, sudden blindness), persistent nausea/vomiting.
This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (fungal infections). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, skin lesions/sores, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, new or worsening swelling/pain in the joints, swollen glands, loss of appetite/weight loss, chest pain, fast/irregular heartbeat, severe stomach/abdominal pain, yellowing eyes/skin, dark urine.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
